2 Operating on battery power 34
• 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 port if no devices are connected to this port.
You can do this through the BIOS Setup Utility. See “Others” on
page 71.
• Eject the PC Card from the slot when it is not in use, since the PC
Card draws extra power. See “Ejecting a card” on page 44.
• Store the battery pack in a cool, dry place. The recommended
storage temperature for battery packs ranges from 10 to 30
degrees Celsius. The higher the storage temperature, the faster
the battery pack self-discharges.
• The batteries can be recharged about 400 times when used as
directed. Excessive recharging decreases battery life.
• Take care of your battery pack and AC adapter. See “Taking care
of your computer” on page iv of the preface.
Battery-low warning
You never have to worry about battery power as long as you are using
the AC adapter. However, when you operate the computer on battery
power, pay extra attention to the battery gauge on the status LCD.
Warning! Connect the AC adapter to the computer as soon
as possible. Data is lost when computer power is cut off
during Standby mode.
