Troubleshooting
Problem
The critical low-battery error
message appears, and the
computer immediately turns
off.
The computer does not return
from sleep mode, or the sleep
indicator stays on and the
computer does not work.

If the processor overheats, the computer will automatically
enter sleep mode to allow the computer to cool and to protect
the processor and other internal components. Check that the
computer is properly ventilated and not hot to the touch.
Check the sleep mode settings. The computer enters sleep
mode (the sleep indicator turns on) immediately after Power-
on self-test (POST).
Connect the AC adapter to the computer, or replace the bat-
tery with a fully charged one.
Check the sleep indicator light to confirm that your system
is in sleep mode. If it has turned off, your computer has
gone into hibernation mode. Press the power button to exit
hibernation mode.
Check that the battery is charged. A depleted battery will
cause the computer to automatically enter hibernation mode.
If the battery is depleted, connect to AC power and press the
power button to exit hibernation mode.
If the system still does not return from sleep mode, your sys-
tem has stopped responding. Reset the computer by pressing
and holding the Power button for 4 seconds or more. Unsaved
data may be lost.
If the computer fails to reset, unplug the AC adapter and
remove, then reinsert, the battery.
