Power 3-7
• 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.
3.1.6 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 notebook on battery power,
pay extra attention to the warning beeps and the indicator light on the
display panel. The indicator flashes when the battery power is low.
The following signals indicate a battery-low condition:
• The buzzer generates four short beeps every minute, if you enabled
the Battery-low Warning Beep parameter in Setup
• The status indicator flashes at regular intervals until battery power is
depleted
When you receive a battery-low warning, you have around three minutes to
save your work. If you do not connect the AC adapter within this period, the
notebook enters hibernation mode if the Sleep Upon Battery-low parameter
in Setup is enabled and the following conditions exist:
• There is enough battery power left to save system information onto the
hard disk.
• The reserved disk space for saving these data is larger than the
combined system and video memory size (Sleep Manager).
