2.1.62.1.6 Battery-low WarningBattery-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 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:
q The buzzer generates four short beeps every
minute, if you enabled the Battery-low
Warning Beep parameter in Setup
q The status indicator flashes at regular
intervals until battery power is depleted
When you receive a battery-low warning, you have
around two minutes to save your work. If you do
not connect the AC adapter within this period, the
computer enters hibernation mode if the Sleep
Upon Battery-low parameter in Setup is enabled
and the following conditions exist:
q The hibernation file created by Sleep Manager
is present and valid. See section 5.1.
q There is enough battery power left to save
system information onto the hard disk.
Otherwise, the computer enters standby mode.
