3.1.5 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 Sleep Manager utility to reserve hard disk space for the
hibernation function.
• Use the AC adapter whenever possible so that the battery is reserved
for on-the-go computing.
• Keep the battery pack in the notebook 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 Setup. See sections 6.1.
• 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 500 times when used as
directed. Excess recharging decreases battery life.
• Take care of your battery pack and AC adapter. See sections 1.2.2
and 1.2.3 for details.
