How to increase your Dell laptop battery life time
Dell Latitude D830 battery life time can be increased or decreased depending on the applications and tasks that you have your laptop doing. This article will tell you how to increase your Dell Latitude D830 battery life time.
Dell Latitude D830 battery life time can be increased or decreased depending on the applications and tasks that you have your laptop doing. For example, if you are playing a DVD movie, much power is being used, shorter time will your Dell Latitude D830 battery be used. If you are burning a CD-R/CD-RW or playing a full screen 3D video game, much power is being used. All these things take more power and in effect lessen the amount of time that you have in “portable” mode.
It is best to try to plug the laptop into the wall if possible in these situations. Remember that you can also get car power adapters for your laptop; this will charge your Dell Latitude D830 battery and power your laptop while you are on the road. Programs that take little power (giving you longer laptop battery life) include word processing programs like Microsoft Word or Corel Word Perfect, Microsoft Excel, Microsoft Access, Outlook Express, Internet Explorer, AOL, CompuServe, or any similar programs. Even the colors displayed on your screen can affect your Dell Latitude D830 battery life. Lighter colors take more power to produce. External connections such as USB Mice, USB Scanners, Memory Cards, Zip Drives, etc. all take more power from your precious Dell battery life. Keep these things in mind when power is of the essence.
Here are some tips to extend the life of your laptop battery:
1. Power down the display
Lowering the brightness may give you as much as an extra hour of runtime. And to increase even more the lifetime of your laptop battery lower the screen resolution and color depth. This will decrease the workload on the GPU, thus extending the battery runtime.
To change this settings follow the steps below:
2. Turn off unused devices
Many new notebooks provide a hard-wired On/Off switch for the Wi-Fi radio for this reason.
To save even more power go to the Control Panel, select System-->Hardware-->Device Manager, and disable the following items: Ethernet adapter, infrared transceiver, and Bluetooth radio . You should do this beacause having Bluetooth enabled and not using it actually consumes quite a bit of power.
3. Decrease hard drive activity
Defragmenting your hard drive regularly will decrease the frecuency with which your hard disk has to spin, therefore the dell inspiron E1505 battery will last longer. This is due to the fact that defragmentation optimizes the placement of the data on the drive and when a program makes a request for certain data it can be found more quickly.
To defragment your hard disk follow the steps in this article.
Another way to decrease hard drive activity is to set your paging file to a fix value, and this value should be around 1.5 times the amount the RAM you have installed on your computer.
To set the paging file go to the Control Panel and click through System -> Advanced -> Performance Settings -> Advanced -> Virtual Memory Change.
4. Disable startup items
Startup items are programs that load into memory every time Windows boots up and cause other open applications to spill over virtual memory and adds to the CPU load, shortening battery runtime. Here is how to remove some of them that are not necessary.
5. Condition the battery
Battery memory is where the dell inspiron b120 battery becomes conditioned to run for less time than it is designed to run. Say for example, you run your computer on latitude d830 battery for an hour and then you plug it back in to let it recharge. The battery will become conditioned to run only an hour before it runs out of juice.
To correct Battery Memory problems, you must completely drain the dell battery and recharge it. To completely drain your dell xps m1330 battery, you must go into your Windows Control Panel and select Power. Then you must turn Power Management Off. Next, you must go into your BIOS and make sure that if there is a power management setting there, that you turn it off as well. In most cases, once you are inside the BIOS, you will highlight Power Management and press Enter. Then locate the item Hibernation at Critical Battery, and by using the Minus sign, change the setting to Off. Once these steps have been completed, then use your Escape key to return to the top level menu, and select Save Settings and Exit.
Once you have completed turning off the power management in both the BIOS and the Operating System, you must unplug the computer, turn the computer on and let it run until it completely runs out of electricity. Then you should charge the battery for 12 hours. At the end of the charging cycle, then run the computer again until the inspiron e1505 battery is dead, and then charge the battery for 12 more hours. You should repeat this process four times, before returning the computer to its original power management settings.
A great little tip to keep in mind is that if you do keep your laptop plugged in for an extensive period of time REMOVE the battery. Let it discharge and give it a break. This will extend your battery life quite a bit.
Another way to condition your battery is to keep it cool. It's best to use (and especially charge) your batteries at room temperatures. Extreme conditions can drain your battery quickly.
