Optimizing Battery Life
This section helps you get the most out of battery operation.
Optimizing battery life prolongs the charge/recharge cycle
and improves recharge efficiency. Follow these suggestions
to optimize and maximize battery power:
❑
Purchase an extra battery pack.
❑
Use the PhDISK utility to reserve hard disk space for the
Hibernation function. See “PhDISK” on page 73.
❑
Use the AC adapter whenever possible so that the
battery is reserved for on-the-go computing.
❑
Keep the battery pack in the computer powered by the
AC adapter. The constant trickle charge maintains the
battery level to eliminate the battery self-discharge
effect. The charge-in-use function also charges the
battery pack.
❑
Disable the parallel and serial ports if no devices are
connected to these ports. You can do this through the
Setup Utility. See “Advanced” on page 89.
❑
Eject the PC card from the card slot when not in use,
since the PC card draws extra power.
❑
Store the battery pack in a cool, dry place. The
recommended storage temperature for battery packs
ranges from 10 to 30 degrees C. The higher the storage
temperature, the faster the battery pack self-discharges.
❑
The batteries can be recharged about 300 times when
used as directed. Excessive recharging decreases
battery life.
❑
Take care of your battery pack and AC adapter. See
“Care and Maintenance” on page xix of the preface.
