Problem:
The computer does not return from standby mode, or the standby
indicator stays on and the computer does not work.
Solution:
If the system does not return from standby mode, it may have entered
standby or hibernation mode automatically because the battery is depleted.
Check the standby indicator.
v If the standby indicator is on, your computer is in standby mode.
Connect the ac adapter to the computer; then press Fn.
v If the standby indicator is off, your computer is in hibernation mode or
power-off state. Connect the ac adapter to the computer; then press
power button to resume operation.
If
the system still does not return from standby mode, your system may
stop responding and you cannot turn off the computer. In this case, you
need to reset the computer. If you have not saved your data, it may be
lost. To reset the computer, press and hold the power button for 4 seconds
or more. If the system is still not reset, remove the ac adapter and the
battery.
