Responding to Low Battery Conditions
The computer generally will notify you when you are reaching a low battery
condition by the following actions:
Four short beeps per minute (unless battery warning is disabled)
The battery low warning is automatically disabled when the AC Adapter
is installed on the notebook, regardless of the charge condition of the
battery pack.
If the AC adapter is not plugged in within three minutes of a detected
battery low condition, the notebook enters Suspend mode (if low battery
suspend is specified in setup). When the notebook enters Suspend
mode, it issues one beep, saves contents of RAM to disk and powers
down the unit.
The Notebook returns to the normal operating mode when the power
switch is activated. The unit then recovers RAM information from the
hard drive and restores the unit to its previous "On" condition.
