Tips for conserving battery power on notebook PCs

You can manually change the power consumption of your notebook PC and conserve HP 510 battery power.

• Reduce the brightness of the screen to the minimum readable level. Use the Fn and F7 or F8 keys to adjust the brightness.
• Remove peripherals when not in use. External hard drives, CD-ROMs, Zip drives, PC cards, and other peripheral devices can draw power from your battery even when they are not in active use. Disconnect them when you have finished using them.
• Reduce the speed of your processor. The faster your computer works, the more quickly it uses up the supply of power. By cutting down on processor speed, you can extend the charge of your battery. Methods to reduce processor speed vary from model to model, and your manual should provide instructions for doing so.
• Turn off the Wireless On-Off button when it is not in use. If your notebook has one, press the Wireless On-Off button so that the light turns off.

Battery care practices

HP G60 Battery cells suffer gradual, irreversible capacity loss over time. Such aging occurs more rapidly as temperature and discharge loads increase. Here are some suggested ways to minimize the capacity loss for your battery.

• Store Li-Ion batteries between 20C and 25C (68F and 77F) with 30% to 50% charge.
• Do not leave batteries exposed to high temperatures for extended periods. Prolonged exposure to heat (for example, inside a hot car) will accelerate the deterioration of Li-Ion cells.
• Remove the battery if the notebook will be stored (turned off and not plugged into AC power) for more than 2 weeks.
• Remove the HP G62 battery if the notebook will be plugged into AC power continuously (via a wall adapter or docking station) for more than 2 weeks.

Note: Recommendations for battery use and storage are covered in the HP User Guides for each model.

Dell XPS M1530 battery customer ratings

Owerhouse of a battery. Charge lasted far longer than the 6 Cell I had prior. I still liked the look of my computer even though this battery was bigger (More bigger than inspiron 1520 1720 9cells battery). The extra weight was not a problem (I am female and not very big.)

It Made my computer (XPS M1530 Laptop) so hot I had to return it and buy the 6 Cell. I could feel the heat off the touch pad and where I place my left hand when typing (where the hard drive is located.)

ConsThis battery is nothing special. Yes it is 9 cells but the poor quality of the battery counteracts the fact that it has 2 extra cells as 9cells latitude D620 battery and latitude D820.

I called tech help who did verify that the battery has more "mass" therefore would be hotter. I was surprised by this because what I had read here had me thinking it would be cooler than the 6 cell. It wasn't. Too bad it was neat.

In all , this 9 Cells XPS M1530 battery is more powerful than 6 Cells XPS M1530 battery, also it become more hotter than 6 cells..
