Problem Solution
Sleep/Hibernation Mode
The computer enters sleep
mode unexpectedly. Check that the battery is charged.
If the processor overheats, the computer will automatically enter
sleep mode to allow the computer to cool and to protect the pro-
cessor 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).
The critical low-battery er-
ror message appears, and
the computer immediately
turns off. Connect the AC adapter to the computer, or replace the battery
with a fully charged one.
The computer does not
return from sleep mode,
or the sleep indicator stays
on and the computer does
not work. 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 system
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.
