this Dell laptop battery is a nightmlare. i bought 2 defective ones in a row and now dell will only refund one of them. the first one didn’t charge at all. after 2 weeks, the second one doesn’t charge past 5% of its capability. Dell will not refund me for the first one because their agents never connected me to the right # after I purchased the second one. Now i am over the 21 days. Dell has problems.

This battery only lasts a few months when I checked the price for a replacement I got shocked. I will try other batteries not from dell and check quality and price, maybe I can get the same performance as the oem but without wasting more money.

Saving my laptop battery life methods

We all like quests… right?? Well, mine has to do with getting the most out of my Sony VGP-BPS9 on my aging laptop. Aging that includes the power-providing battery. I already have a head start on this with my laptop specs. It is a Dell Inspiron 700m Battery . It is also based on the Centrino platform, which was Intel’s first major play into laptop powersaving. Included within are an arsenal of powerful components that use minimal power (at the time).

My specific laptop was based off of the Carmel platform. It includes an Intel Pentium M 1.6GHz processor with variable speeds ranging from 600MHz to 1.6GHz, the Intel 2200BG wireless networking card, and the (unfortunately) low-powered 855 Chipset which includes Intel Extreme Graphics 2. Also included is a 12.1″ widescreen LCD Powerful Dell Inspiron 6400 Battery, which I am sure uses less power than some of the larger screens out there.

I already had low power-consumption in mind when I installed Slackware (started with 10.2). I installed cpufreq-utils and cpufreqd which allowed me to adjust my processor speed depending on certain power conditions. I also purchased a larger battery (on this model the Dell Latitude D830 Battery is in the back, so the larger one extends further out the back). The original was a 4-Cell that provides 2200mAh. I replaced that with an 8-cell that provides 4400mAh of power. When the battery was new it provided a whooping 5 hours of battery life. Sadly batteries will dwindle and the power it is capable of putting out will shorten over time.

So to get to the point of my quest, Dell Inspiron 1525 Battery was to get the maximum life out of my laptop. The reason was that I was getting ready to go on leave. I currently am stationed at Ramstein Air Base in Germany, and flight times back to the states are kinda long. So I wanted to be able to use my laptop for as long as possible while I was flying (partially due to the fact that I can’t sleep on planes, even when assisted with sleep medication). So with the help of Google, I was able to come up with the following.

First things first, I found I needed to re-compile my kernel. This will be distro-specific, due to different distros compiling kernels different ways. Mine will all be based off of Slack 12.1 which is the version I was running at the time with my Dell Latitude D630 Battery. The biggest reason for me, was to included tickless-support, which basically only wakes up the processor when there is something for it to do.

Next was to get a program called PowerTOP (PowerTOP needs certain things built into the kernel, the items needed are listed on their site). It is developed by Intel and is used to show what is causing your processor to wake from its low power state. The other benefit it gives is it will tell you some information on how to use less power Dell Latitude D520 Battery, such as disabling Bluetooth, or setting a lower scan rate for your wireless. It provides hotkeys so you can change these directly in the program without exiting. It also provides the actual commands that it uses to change these. This way you can make them into a script (like I did).

Some of the functionality it wants to change may not be beneficial for everyday use of a laptop (like disabling Bluetooth). So if you want some of these to run everytime you run your laptop you could add them to your system startup with Dell Inspiron 1721 Battery, which in Slackware is under /etc/rc.d/rc.local (distros vary in their startup procedures, so yours may be different). For other times (like when on a plane and you don’t want any wireless devices running) you can make a specific script for it that you run when needed.

Another tool worth mentioning is laptop-tools. This is a script that will run in the background and whenever the laptop starts using the battery, it automatically will provide powersavings. There is a detailed article about what it does here.

Now come the common sense items. People should realize these, but lets face it… everyone has brain-farts.

• Dim your laptop screen to the lowest level still viewable. The higher the brightness of your LCD screen, the more power your backlight will consume.


• Don’t use your Dell Inspiron 1420 Battery CD/DVD drive. It uses a lot of power to spin a disc. Their are plenty of tutorials to convert your dvd’s to a file on your hard drive.


• Don’t use external devices. Even an external mouse or usb drive will use additional power.


• Depending on your distro you may want to consider using a different window manager. Some window managers have a lot of programs running in the background that will take up processing power and in turn use more of your battery. While I normally run KDE 4, I use windowmaker when I am trying to save power.


• Disable 3D acceleration in your Dell C1295 Dell KD476. Again, this will use unnecessary processing power. You can do this in your /etc/X11/xorg.conf file by commenting out the Load dri and glx modules. Just put a # in front of them.


• Disable any unused services. If you won’t be using your webserver or database software, there is no reason to be running those in the background. You can add any of these to your powersave script.


• Disable any unused hardware. You can do this by removing the modules. If you won’t be using usb, then remove it. Some of the devices you may want to consider disabling are: firewire, pcmcia slot, bluetooth, wireless, card readers, and more this can saved Dell Inspiron E1705 Battery life.


• The more obvious one is, if possible, buy a larger battery. This will be dependent on the laptop, because some laptops do not have any larger batteries available. Worst case, buy a new one to replace your aging battery.

Unfortunately I don’t have an amount of extra Dell Latitude D820 Battery life this gave me, but I did lower my wake-ups from idle per second by more than 400 wake-ups. And this is just when I am using KDE4. With switching to windowmaker I was able to lower the total amount to 40-60 wake-ups per second. Granted, when I am running my video player that number does go up, but the lower the number of wake-ups the less power your processor will consume.

How to prolong digital cameras battery life

At present, digital cameras have been widely used. How to extend Acer battery life, 7 kinds of methods introduced here:

(A) Less flash. Flash power consumption is the largest in the Kodak and Dell KD476 battery Dell Y9943 battery automatic mode and PASM mode, the flash can be turned off (scene mode exception).

(B) Turn off auto-zoom. Camera’s default setting is continuous AF zoom, which is the camera around the scene on a continuous zoom, in the setting menu will be a continuous zoom into a single, the icon for the Dell G761battery Dell G5260 battery AF.

(C) Reduce image editing times in the camera . Applications readers up in the computer editing view pictures, if we did not have the camera to edit view pictures, would be able to save half of the electricity.

(D) a change in image format. According to their Latitude D630 Battery actual needs, the pictures taken will be transferred as far as possible into the low-storage format. This camera can speed up time to write disk, naturally a power-saving.

(E) Viewfinder LCD screen when you minimize the use of multi-use Latitude D830 Battery EVF viewfinder.

(Vi) to reduce the number of zoom. Telephoto lens to narrow the disparity is indeed a lot of power Yo!

(7) in the setting menu to switch off Latitude D820 Battery unnecessary switches.

Jack hopes that help you.
