Preserving BTRY Life in DELL notebooks

All DELL Notebooks 

** Keep track of how much power is left in your battery to avoid unexpected system shut down
or data loss.

** Reduce the brightness of the screen to the minimal readable level. Dell notebooks have
keyboard buttons that allow you to do this easily.

** Put your computer to sleep or standby mode whenever you are not actively using it.

** Remove peripherals when not in use. External hard drives, CD-ROMs, zip drives, modems,
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.

** The faster your computer works, the quicker it uses up the supply of power. The heavy
workload like 3D applications, playing CD's/DVD's while working on battery consumes more
power, which shortens battery life. The fact that battery life varies so significantly depending
on the particular mix of applications running on a portable system is one of the main reasons
that the actual battery life seen by end users can vary from the estimates published.

** Deep-discharge the battery every few weeks for optimum performance. Deep-discharge
occurs when your Dell notebook is used on battery power until the charge is at 0% (the system
will automatically go into hibernation). At this point, attach the AC adapter and charge to
100%. Partial charge or discharge causes a lack of uniformity of activated chemicals in the cell,
and may cause performance degradation.
