apple ipad score well on battery life (2)

“If you’re mainly a Web surfer, note-taker, social-networker and emailer, and a consumer of photos, videos, books, periodicals and music… this could be for you,” Mossberg said.”If you need to create or edit giant spreadsheets or long documents of Lenovo thinkpad r61 battery , or you have elaborate systems for organizing email, or need to perform video chats, the iPad isn’t going to cut it as your go-to device,” he wrote.

Pogue, who wrote a review for techies and one for “everybody else,” highlighted shortcomings versus laptops.”The bottom line is that you can get a laptop for much less money with a full keyboard of Sony VGP-BPS8 battery , DVD drive, USB jacks, camera-card slot, camera, the works,” he wrote.Mossberg said the device was “wicked fast,” but had “annoying limitations.”

“For instance, the email program lacks the ability to create local folders or rules for auto-sorting messages, and it doesn’t allow group addressing. The browser lacks tabs. And the Wi-Fi-only version lacks GPS,” he said. Both noted iPad’s support for the popular Flash video technology thinkpad t60 battery and questioned consumers’ willingness to carry another device along with their laptop and phone.

“If people see the iPad mainly as an extra device to carry around, it will likely have limited appeal,” Mossberg said. But they admired iPad’s speed and ease of use. “The iPad is so fast and light on Lenovo 3000 n200 battery , the multi-touch screen so bright and responsive, the software so easy to navigate, that it really does qualify as a new category of gadget,” Pogue said, adding it would appeal to less tech-savvy users.

Dell XPS M1730 battery problems:

Thats maybe the dell mainboard and adapter probelm : Just last night I started receiving a message saying, “The AC Power Adapter Type cannot be determined. Your system will operate slower and the battery will not charge. Please connect a SONY VGP-BPS8 230W AC Adapter or Higher for Best Results”.

Customers Rating :

Doesn’t hold much charge, maybe an hour (when it was NEW). Now that it is a year old, it holds ZERO charge. If I unplug my computer, the battery holds no charge and the computer crashes immediately. Poor quality, poor value.

The battery that came with my M1730 is so weak my computer shuts down 10 sec after I unplug it. I did not use the battery much – always plugged in. The price is absolutely ridiculous for something that only lasts a year and provides 1 hour of power.

In the end the xps m1730 battery is a new battery as sony Sony VGP-BPS8 VGP-BPS9 VGP-BPS9/B VGP-BPS13.There maybe some replacement in the market, you can select a cheap replacement for your OEM battery when you long working with battery. As the frequent “long time discharging” can damage your OEM battery.

why laptop battery suddenly stop discharging

Maybe we all face this situation : Some times we should travel to some place as the business or holiday. You know the 12 hours or more journey time is too wearily. So we like enjoy ourself with our laptop to watch movie or play game. Suddenlly the Dell Latitude D620 Battery stop dischargging in the 70% power state or more. You maybe very confuse about this : maybe some problem with my laptop or my laptop dead. In fact most of them are caused by the temperature or the over-Current.

Most laptop batteries have the protection circuit. When the laptop battery temperature is too high or discharge current is too large, out of laptop battery protection circuit action standards. Thus causing the Dell Latitude D630 Battery power automatically stop discharging and force the issue.

The most common situation is that laptop battery is running at full speed . The Dell Inspiron 710m Battery current is too large to result in automatic protection. For example, from the drive to capture the contents of DVD discs into the mobile hard disk, when a large number of both host and peripheral power consumption, is likely to make current standards of protection beyond the battery. D0 not panic in that case. You only used to disconnect peripherals and wait about 10 minutes, then you can reboot the machine.

There is also a common situation : using the battery in a hot environment and high-load operation, , so that the ambient temperature plus the heat generated by the battery self-discharge Dell xps m1530 battery protection circuit may exceed the preset temperature, which is particularly high frequency P4 machines in high-temperature environment may occur after high-speed operation.

Encountered such a situation should remove the batteries placed in a cooler place (remember not to put refrigerator frozen!), After half an hour should be back to normal. High temperature for the lithium Dell TC030 Dell PC764 battery damage is relatively large, less than a last resort and should be avoided in high-temperature environment and high-load operation.

Choose suitable software for you laptop

As with a desktop machine, it’s easy to end up paying more than you need for a package because it’s been buffed up with bloated software. You will, however, need an operating system, and the overwhelming majority of laptops use Microsoft Windows in some guise Inspiron 6400 Battery. Linux hasn’t really made inroads into the portable market as yet, and thus Windows XP Home or Professional will more than likely be bundled in.

Some leave it at that, others will include one or more of the following: DVD playback software (useful, but not that expensive to buy), anti-virus package (never to be sniffed at), some form of office package (if it’s Microsoft Office, that accounts for much of the price at hp compaq 6510b battery, while the likes of Ability Office barely dent it) and CD/DVD burning software (the bundled stuff is generally quite limited, but enough to do what the majority of people need it to do).

If a portable machine goes awry, it costs a great deal more to fix than a desktop PC Dell Inspiron 5100 Battery. For that reason it’s worth looking into warranty packages, although don’t instantly snap up the one that your retailer is offering you. Shop around some third party services and see if you can get a better deal.

Hopefully, all of that has given you some useful pointers as to what to look out for. The usual rules should apply when you do finally go shopping though: research your purchase carefully, ask as many questions of your retailer as you need and make sure you pick the machine you want Toshiba PA3535U-1BRS, not the one they want to sell you. Oh, and don’t forget to check out the machines we’ve tested at IT Reviews.

Where is Laptop using heat come from?

We are using the notebook for some time. Weoften found that notebook slowly get hot after using for a while, especially the bottom of laptop. The situation occur frequently in Summer. Where is laptop using heat come from?

When the machine overheating, some harm reasult happend: laptop system halted, restart, and even laptop parts burn (espacilly laptop battery). Which laptop part produce such a large amount of heat? Here I will give us a presentation.

As the desktop CPU’s power consumption and heat is very large. It can not be used in notebook as Dell WW116 , so mobile processors is specifically designed for notebook. Many notebook CPU processor power consumption are over 20W, particularly in the mobile Pentium 4 processor. Though there are a lot of technology tips make notebook average energy consumption low, but the peak is still very high (more than 30W) when using. Many of these energy consumed will come into heat dissipation. Therefore we should always check the clearance of xps m1730 battery CPU fan air vents. Make sure there are no stolen goods block the air vents, that cause the heat can not dissipate. If the notebook CUP silicone hardening, we should replace it in time.

First, the XPS M1530 Battery notebook cooling heat is mainly come from the CPU working heat. But CPU heat is not the all. And the early CPU processor heat is not very large. Just use some simple passive cooling method that can satisfy the cooling needs of the machine. That is the heat sink cooling as we usually known. However, as the continuing escalation of CPU processors, while in the Pentium processor century, the processor’s cooling is the big problem.

Secondly, the graphics card heat is also a large proportion. Early graphics cards heat is not large, but now a lot of high-end machines such as Inspiron E1505 Battery Inspiron E1705 Battery often configure the ATI Mobility Radeon HD4750 or GeForce GT240M such a good graphics card, so the heat also increase a lot.

Finally, there is some other hot parts, such as memory, hard drives, laptop battery, are also a number of laptop heat source.

How to charge your laptop battery properly?

During the the process of notebook using, we need no to deliberately charge the Inspiron 6400 Battery to 100% state or fully discharged laptop battery to automatic shutdown protecting. The correct way is that charge the battery in 20% state and stop charging in 98% . If the machine has the power calibration procedure, when the battery standard-by time significantly reduced. Then calibrate the battery in time to active the protection circuit performance.

For early notebook batteries as Dell XPS M1730 Battery (Ni-MH Ni-MH or Ni-Cd Ni-Cd), really need to fully charge and discharge in order to maintain good battery capacity. But for the lithium battery is not necessary even it may damage the battery.

In fact the lithium batteries has a little memory effect. The lithium VGP-BPL9 battery materials is very sensitive to the conditions as temperature, the use of frequency and so on. The battery will be aging after used for some period time (standby time reduced). The natural wear and tear is an important reason, and inadequate maintenance is another important reason.

A well-designed lithium batteries have a very good protection circuit to prevent excessive charge and discharge.As over-charging and discharging of the Sony VGP-BPL8A battery will be the rapid reduction activity. Under the protection of protection circuit, the user fully charge and discharge the battery several times, in fact, impossible to achieve had “full” level.

Sometimes WINDOWS show that ThinkPad T61 Battery capacity is 20% or more, you can use 30 minutes. But after used 10 minutes or less the machine suddenly automatically shut down. The reason is that the battery has been aging, the battery protection circuit can not monitors the battery real capacity. In the normal battery depletion, the protection circuit original parameters have been unable to properly reflect the actual situation of the battery

So power calibration procedure is to correct the benchmark protection circuit parameters to accurately reflect the actual capacity of the IBM ThinkPad R61 Battery. This correction process will often take two or three complete charge and discharge. As previously mentioned, fully charge and discharge will reduce the battery activity. It is not frequently used, usually once a month.

Microcontroller Control Software Design

The key is to balance the control of the module parameters of the Dell Inspiron 6400 Battery voltage collection and trigger pulse output FET and battery status to determine the control software to achieve a balanced charge and discharge at the same time should also be able to realize the battery overcharge, over discharge instructions to protect the other When the battery of VGP-BPS12 temperature exceeds its operating temperature range can also be a timely manner to protect the output instructions.

Experiment and result analysis

With the two lead-acid VGP-BPS8, VGP-BPS8A batteries do 12V/4Ah comparative experiments, before the experiment, respectively, the battery discharges to the voltage is not balanced, and then use the module to do a balanced two-way balanced charge and discharge experiments, test the initial conditions the same. The experimental results shown in Figure 4,5, can be seen from the diagram in the absence of a balanced case, the charge and discharge of the latter, the battery voltage difference between the more and more, while the two-way balance of modules in the process of charging and discharging effectively narrowed 2 between the VGP-BPS9, VGP-BPS9/B battery voltage, particularly in the charging and discharging the battery too late to avoid the charge and over-discharge, protect the battery pack.

In the future, PHS mobile phone charger can be universal.

“At present, the alliance has not raised objection to the implementation of standards manufacturers, so we are on schedule the implementation of the standard expressed optimism about the prospects.” Yesterday, China’s fixed and wireless terminals stakeholders Secretariat of the VGP-BPS9/S, VGP-BPS9A/B League told this newspaper.

Notebook battery fully charge and discharge error

Notebook computer equipped with the original battery, after a period of time after use, there will inevitably be the case of standby time. Some users said: “depth with repeated charge-discharge method, be able to resume the performance of the battery, thereby extending the battery life.

To a correct understanding of this issue, start a notebook about the type of Sony battery used. As we all know, in 1995, before the production of notebook computers are basically used to power nickel-cadmium batteries. In the use of such batteries, if not the correct way of charging and discharging, the battery will have a “memory effect”, thereby reducing the battery’s actual capacity, the elimination of this “memory effect” is the best way to repeatedly charge and discharge depth manner. With the emergence of nickel-hydrogen batteries, battery capacity has improved significantly, but the “memory effect” did not completely eliminate the shortcomings.

In recent years, lithium-ion batteries in notebook computers has been rapidly increasing, largely as a result of lithium-ion batteries have been the elimination of the “memory effect” problem, it is used repeatedly to restore the depth of Dell inspiron 1545 battery charge-discharge performance of the method is not applied. But why lithium-ion battery capacity or the will to reduce the problem? Have a fundamental reason for this situation is used in notebook computers and the original lithium-ion battery in the built-in battery management systems.

Battery Management: At present, in notebook computers, almost all adopted the “battery management” and “charge-discharge control” of two chip-level management systems. The “battery management chip” placed in the notebook computer itself, the chip registers in the memory of the computer used in the capacity of lithium-ion Inspiron 1545 battery, operating temperature, ID serial number, charge-discharge state, the cumulative number of charge-discharge and other important information. In the use of these data, the need to constantly refresh the actual situation. The battery built-in “chip control charge and discharge” the most important role is to monitor and control the battery charge and discharge the entire process and be documented.

Charge: Lithium-ion rechargeable battery the whole process is divided into “fast charge constant-current” and “reduced charge constant current” two stages. The so-called “constant current fast charge” means charge has just begun, the charge current and charge voltage to follow a fixed battery terminal voltage gradually increased until they reach their nominal voltage of the charging method. When the inspiron 630m battery terminal voltage has reached the standard value, the controller will automatically turn into “reduced charge constant current” phase, when the charging voltage will no longer continue to rise, while the charge current to follow the battery capacity is rising gradually diminishing, and eventually reach zero, so they all completed a KD476 GD761 battery charging process.

At the same time, the charge generated by the process of charging voltage, current and time data curves will be recorded in the VGP-BPS8 battery’s “charge-discharge control chip” of the memory. “Battery management chip” is through access to th

ese data, calculated by the sample data such as battery capacity, which is, in Battery Information in numerical Wh read.

Fixed: After repeated charging and discharging the Dell Inspiron 1520 Battery after use, its built-in chip in the charge-discharge data will of course be changed. If at this time “battery management chip” has no chance to re-read the newer, more complete data, it calculated the battery capacity will not be accurate of course, to the user the feeling seems to be reducing the capacity of the Dell Latitude D820 Battery, and the fact that the actual capacity of the battery has not really reduced. Some bring their own brand of rechargeable laptop management software working principle, the process is in charge refresh “charge-discharge control chip” memory of the data, thus ensuring the “battery management chips,” the correctness of calculations.

A close look if you have the use of laptop manuals, will be found that “a month in the use of computer time, should make a full fujitsu battery charge and discharge operation” note. Its main purpose is to use the depth of charge and discharge the way to amend the charge and discharge control chip register data in the curve so that the battery charge control and battery nominal capacity and the actual situation, as a result the correct value of the battery capacity.

Electric cars

Electric cars can not be a 2020 high-volume mainstream product, according to Boston Consulting Group, recently wrote an article about car laptop battery, and through Dave Guilford Automotive News written by a published study.

The main reason is the hybrid did not become widespread dissemination is due to the huge cost of the Dell Inspiron 6400 Battery. In the hybrid vehicle lithium-ion battery current price is 1,000 yuan to 1,200 yuan per kilowatt-hour. Vehicle manufacturers can not achieve their long-term costs per kilowatt-hour objective of 250 hours.

Today’s prices mean that the present 20 million kilowatt hours of electric car Dell Latitude D620 Battery cost about 20,000 yuan. While the prices may drop to 8,000 by 2020 will not be low. Consumers want to have a three-year cost recovery period to purchase an electric compared to internal combustion engines, Mosquet said.

In 2020, the annual report, 26 percent, in the main vehicles sold in developed markets will have some form of Dell XPS M1730 Battery power. This would translate into about 14 million.

However, the study is expected, the vast majority – about 110,000 – will be the sale of hybrids only about 1.5 million electric vehicles annually. Some on-board rechargeable Dell Inspiron E1505 Battery means to account for another 1.5 million electric vehicles, the report said.

Mosquet said that there may be legitimate reasons, such as development covers the sharp rise in oil prices, the possibility of electric vehicles. As well as the electric part of the annual 1.5 million units can be used for dell inspiron 1520 battery manufacturers and a number of car manufacturers profitable, he said.

But Mosquet said that car manufacturers should be cautious: “We are now saying is be careful.”

The report assumes that the cost of batteries and electric in hybrid electric vehicles purchase price. It does not include the Dell Inspiron E1405 Battery may actually be leased, often to exchange the possibility of this has been a variety of businesses, including a better place to propose.

What’s wrong with my Compaq Evo N610c ?

Recently,I donn’t know why my Compaq Evo N610C Battery struck. So I tried to search through google for any specific answers to my problem but to no avail. I reiterate thatI’d appreciate any suggestions on how to get my Battery Pack operating correctly again.This is going to be a very long post so please bare with me. I’ll start from the top.

I bought a Refurbished Compaq Evo N610c Laptop about 6 months ago,of course including the stupid Compaq N610C battery. It was working fine until about a month ago when I noticed that the AC Adapter cable started to make a funny noise whenever I plugged it in. After having a closer look at the AC Adapter, I found that there was a crack in the middle of the power pack which is exactly where the noise was coming from. But by the time I noticed that there was something wrong with the AC Adapter, the laptop would not turn on from the mains or the battery.

So I went and bought a replacement AC Adapter from batterymag.co.uk. It arived here and the laptop now started to work from the mains again. But now, it will not turn on from the battery. This is now my next problem.

The new AC Adapter recognises and charges the battery – the orange light turns on when I connect the AC Adapter to the mains and the vgp-bps13 is connected to the Laptop. However, whenever I try to turn the Laptop on from the Battery (without the AC Adapter connected), it makes a very weird and loud noise. It will boot up Windows from the battery and then 5 minutes later, the Laptop just turns off by itself.

I’ve had a look at the Control Panel under Power Options in Windows and it says there that the battery is 100% charged but the current power source is “AC power”. This doesn’t make sense because the AC Adapter is not connected to the Laptop and it’s not connected to a mains socket.

Now I’m thnking that maybe my Battery is the problem. So I went and bought a spare Battery from laptopbatterymag.com. It arrived here, I tried it and noticed similar erratic bahaviour. It would turn on from the battery, it doesn’t make any noise but the Laptop turns off by itself after about 15 minutes of continous use. And again during this time, Windows shows the battery as 100% charged and the current power source as ‘AC Power’. The AC Adapter is not even connected to the Laptop or the mains so I can’t see why it’s thinking that the Battery power is the AC Power.

What am I supposed to do now? Is there something wrong with my laptop? Is there anything at all that I can do to fix this myself? Like cleaning the battery contacts or is there something more sinister going on here?


I’m at a loss at what to do next and I would greatly appreciate your help with this.I have a bit of experience with PC building so if it’s just a case of taking the old one out and putting the new one in then that shouldn’t be a problem. However, I can’t do any soldering – just haven’t got enough experience. I’m more familiar with cables and connectors.

Oh and if you’ve managed to get this far, many thanks for reading the entire post.

Dell XPS M1730 Review

The XPS M1730 is Dell's new 17-inch high-performance gaming notebook, the replacement for the aging M1710 (dell latitude d600 battery). It is based on the latest Intel Santa Rosa platform and features cutting-edge Nvidia GeForce SLI graphics.

Before I start this review I would like to thank Dell for sending us a test unit.

Our test unit specifications are as follows:

• Windows Vista Home Premium


• Intel Core 2 Extreme X7900 (2.8GHz/4MB L2/ 800MHz FSB)


• 17-inch WUXGA display


• Dual Nvidia GeForce 8700M-GT in SLI (256MB each)


• Dual 200GB 7200RPM Hitachi drives in RAID 0 (striped data)


• 2GB DDR2-667 RAM in dual-channel


• Intel Wireless WiFi Link 4965AGN wireless


• Integrated Verizon Wireless Mobile Broadband


• 8X DVD Burner


• 9-cell battery

Build & Design

A simple glance at the M1730 (apple powerbook g4 battery )establishes that this notebook is not for those who do not want to show off. There is no other notebook like this on the market. For starters, the M1730 (dell latitude d620 battery)is absolutely enormous; its weight starts at 10.6 pounds and is two inches thick.

Dell chose an intimidating design scheme for their flagship notebook. The visible exterior has a deep glossy black surface with a 'hydrographic' design pattern. The intricacy of the design can best be seen in a well-lit room. The back of the lid deserves special attention – two clear plastic windowed areas on the sides have a color background that is illuminated by the LED lights; our test unit has the Smoke Grey panels. The XPS M1730 (gd761)is also available with Sapphire Blue, Crimson Blue, and Bone White. In the center of the lid is a large shiny Dell logo illuminated by a bright white LED backlight. The lid is an instant attention-grabber and the most visually striking part of the M1730 (dell inspiron e1505 battery)in this reviewer's opinion. The speakers in the front of the machine are illuminated by LED lights as is the touchpad and its buttons. While the LED lights on the back of the lid do not change colors, the ones on the front can. All the colors in the rainbow are available (more or less) and each speaker as well as the touchpad can be individually controlled via the Dell QuickSet software. The keyboard is LED backlit and visually impressive. This is the first machine I have ever tested with a backlit keyboard and I would like to see more notebooks implement this feature. It is useful in low light scenarios and for those late-night gaming sessions.

The build quality of the M1730 (dell xps m1530 battery )is impressive, as it should be for the price. The chassis feels as solid as high-end competing notebooks from Sager and Alienware. There is zero flex in the palmrest or surrounding area, although the area beneath the display does not feel as solid as the aforementioned surfaces. Pressing on the back of the lid did not affect the display. The undersides of the notebook are made from magnesium and add to the build quality of the machine. In addition, they also help with heat dissipation. Moving to the top of the notebook, there is one display latch in the center of the display and it is solid. Its gunmetal color is a smart match for the black and gray exterior. The lid closes with a reassuring 'click' and holds secure. The front of the M1730 is angled nicely when the lid is closed; the M1730 ibm battery may be big, but it is also sleek. Its front end almost looks like it was aerodynamically designed. The gaps between the various parts on the notebook are evenly spaced and everything fits together well, which shows attention to detail.

Overall I am more than impressed with the level of build quality and the exterior appearance of the XPS M1730 battery. The flashy looks are a selling point of the XPS M1730 (dell latitude d820 battery)– buy this machine to get noticed.

Display

The 17-inch glossy 1920 x 1200 pixel widescreen display that came on our test unit is the only option for the M1730 (ibm t60 battery ). WUXGA is the highest resolution available on a notebook. This display is fantastic; for starters, it is the brightest single-lamp 17-inch display I have seen on a notebook. The high contrast makes colors pop off the screen; blacks are deep and whites are bright and pure. Viewing angles are excellent; the side-to-side angles are near perfect and there is minimal distortion from above and below. The picture is crystal clear and there is no distortion or graininess. Light leakage is minimal, with only a small amount coming from the bottom of the display.

Speakers

The M1730's stereo speakers are located at the front of the notebook below the palmrest area. Two small speaker cones can be seen through the speaker grills; they visibly pulse when playing music at elevated levels. For notebook speakers, the M1730's are wonderful. Treble is respectable and while bass is a bit lacking, it is still noticeable which is not something that can be said about many notebook speakers. Sound is detailed; I could hear bullet shells hitting the ground in games and picks hitting guitar strings in acoustic music. Overall, Dell has equipped the M1730 (dell d630 battery)with two competent stereo speakers which suffice for playing music and games.

The M1730 has two headphone jacks located on the left side, which allows two people to tune into a movie or other audio.

Processor and Performance

I had high expectations for the fully-loaded review unit Dell apple ibook g4 battery sent us. The Core 2 Extreme X7900 a1189 is a rare and special processor in that it will not work in most Santa Rosa notebooks; its TDP is higher than most notebooks’ cooling solutions can handle. The standard Core 2 Duo mobile processor has a 35W TDP in comparison to the X7900's 44W. A heavy-duty heatsink is needed to handle its high heat output.

The real advantage to the Intel Extreme processors is their unlocked multiplier, so overclocking is simple. I ran each benchmark that involved scoring the processor twice; the first time with the processor at its stock 2.8GHz clockspeed, and the second time overclocked to 3.4GHz via the BIOS. The maximum overclock is 3.4GHz. Dell allows the end user to set 2.8GHz (stock), 3.0GHz, 3.2GHz, and 3.4GHz via the BIOS, but they recommend that the machine be run with 2.8GHz.

Testing notes: Prior to testing, I defragmented the hard drive and did a Windows Update. I installed the latest Nvidia drivers (169.04) for the video cards. All frames per second (FPS) benchmarks were done with FRAPS.

Gaming Benchmarks

Gaming is what the XPS M1730 is all about, so the gaming aspect of this notebook deserves a lot of focus. As such, we've broken this aspect of the notebook out into a separate article, the XPS M1730 Gaming Benchmarks can be viewed here.

Heat & Noise

The M1730 a1012 has one of the largest cooling solutions I have ever seen on a notebook. The entire backside of the machine is essentially one giant vent. There are two large-diameter fans in the bottom of the notebook which force outside air into the notebook. During normal use the notebook is nearly silent; the fans come on in intervals and usually do not stay on for more than a minute. It takes a skilled ear to hear the fans even with no background noise. In a silent room, a quiet movement of air can be heard when the fans turn on. While gaming the fans are always on, but again, they are extremely quiet. I noticed that in games that make use of the Ageia PhysX card such as Unreal Tournament 3, the left-most vent jets out warm air and slightly more noise is made. I should note that when the system is overclocked, the fans are locked at full blast which IS noisy. I do not recommend running this machine overclocked due to the noise level.

The M1730 a1022 has a full-size keyboard with separate number pad. It is LED backlit which is a handy feature in a dark or low-light area. The overall feel of the keyboard is not as high quality as the rest of the machine in this reviewer's opinion; the keys feel thin and I do not feel that the keyboard is as solid as it should be. There is an ample amount of flex when slightly more than average pressure is used. On the plus side I like the way the keyboard sounds and most keys are in their normal positions.

Touchpad

The M1730's touchpad has a high-end feel to it. Tracking is reliable and precise enough for most uses. The touchpad buttons feel solid and make a satisfying 'click' noise. The only potential downside to the M1730's a1039 touchpad is its relatively small size; I would not mind if it were a bit larger.

Input & Output ports

Wireless

The M1730 comes with an Intel Wireless WiFi Link 4965AGN wireless card as standard equipment, which supports 802.11a, b, g, and n wireless formats. I had no trouble connecting to wireless networks and it held wireless signals well, even through walls. Oddly enough the M1730 does not come with Bluetoth wireless as standard equipment and our evaluation unit did not have a module installed. It did however have Verizon Wireless Mobile Broadband WAN built in, which worked beautifully. I was able to connect to the Internet over the fast EV-DO network within seconds. I measured download speeds around 1 Mbit/second and upload speeds approaching 700kbps. Built-in WAN can be a handy feature but its usefulness on the M1730 is debatable, since this is the type of machine that will spend most of its life on a desk.

Battery

The battery in the M1730 a1060 serves as more of an Uninterruptable Power Supply (UPS) than anything else. Running with the screen brightness at full while surfing on Verizon wireless WAN, I measured 56 minutes of life. With the screen dimmed and the wireless turned off, battery life improved by about 20 minutes. Consider for a moment how much power this notebook consumes; Dell's regular Inspiron 17-inch notebook achieves almost 3 and a half hours of life with the same battery. With dual hard drives, dual video cards, and an Extreme processor, it is no wonder that the M1730 cannot stay unplugged for long. Anyone buying this notebook is probably not concerned with battery life so I do not view it as a con.

Power Adapter

There are few notebooks that get a mini-review of their power adapter, but the M1730 a1078 is one of those special notebooks. Most will be shocked by the sheer size of this brick. It is so large because it needs to provide over 200 watts of power; the standard notebook power adapter provides 65 or 90 watts. The M1730's adapter weighs several pounds by itself. Its power cord is about twice as thick as the standard Dell power cord. I liked the blue power LED Dell put into the brick; most of the time they are green.

Operating System & Software

The M1730 is available with Windows XP Professional different versions of Windows Vista; ours came with Vista Home Premium 32-bit. I find it rather odd that such an expensive machine does not come standard with Vista Ultimate. I was most surprised at the amount of bloatware pre-installed; there is as much on here as there is on a traditional Inspiron notebook. It took a good half-hour to rid the system of unwanted software.

Customer Support

Dell XPS systems come with special service as part of the price premium. According to Dell apple macbook pro battery , the majority of service calls are answered within 2 minutes. The M1730 comes standard with a 1-year limited warranty and 1 year of XPS warranty support. In-home service is also standard.

Conclusion

Dell has respawned its flagship XPS gaming notebook into an even bigger and more powerful beast. The M1730 is one of the fastest gaming notebooks on the market and is certainly the flashiest. The M1730 is the most attention-grabbing notebook I have seen to date; its exterior appearance is sleek and intimidating. Taking the M1730 to a LAN party is sure to get one recognized. Dell has done a wonderful job with the M1730 inside and out; the software support may not be perfect at the moment but the hardware is all there, which is what counts.
