Battery-low warning
You never have to worry about battery power as long as you ar e using the AC
adapter. However, when you operate the computer on battery po w er, pay extra
attention to the warning beeps and the power indicator on the display panel.
The following signals indicate a ba ttery-low condition:
• The buzzer generates four short beeps every minute, if you enabled the
Battery-low Warning Beep para meter in the BIOS Uti lity.
• The power indicator flashes at regular intervals until battery power is
depleted.
When you receive a battery-low w arning, you have around two minutes to save
your work. If you do not connect the AC adapter within this period, the computer
enters Hibernation m ode if the Sleep Upon Battery-low paramete r in BIOS Utility
is enabled and the fo llowing conditions exis t:
• The Hibernation file created by Sleep Manager is present and valid. See
“Sleep Manager” on page 74.
• There is enough battery power left to save system information onto the hard
disk.
Otherwise, the compute r en ters Standby mode.
Warning ! Connect the AC adapter to the computer as soon as possible. Data
is lost when computer power is cut off during Standby mode.
The following table shows the recommended course of action to take when you
encounter a battery-low condition.
