Screen Problems
When I turn on the computer, nothing
appears on the screen.
If the screen is blank, make sure that:
• The AC adapter is connected to the
computer and the power cord is plugged
into a working electrical outlet.
• The computer power is on. (Press the
power button 6 seconds to force the power
off, and power it on again.)
If these steps are properly followed
and the screen remains blank, have the
computer serviced.
My screen goes blank while the computer
is on.
Your power management is enabled. Do
one of the following to resume from sleep
mode:
• Press any key on the keyboard for 2 to 3
seconds.
• Press the power button.
• Press the windows key.
Sleep Problems
The critical low-battery error message
appears, and the computer turns off.
The battery power is getting low.
Connect the AC adapter to the computer.
The computer enters sleep mode
immediately after Power-on.
Make sure that the battery is charged.
The operating temperature may be too
hot. Move to a cooler environment and try
to wake the computer.
The computer does not return from sleep
mode and the computer does not work.
If your computer is in sleep mode, connect
the AC adapter to the computer then press
the power button.
