Display problems
When I turn on the
computer, nothing appears
on the screen.
• If the screen is blank, make sure that:
- The battery is installed correctly.
- The AC power 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
again for confirmation.)
• If these items are properly set, and the screen remains
blank, have the computer serviced.
When I turn on the
computer, only a white
cursor appears on a blank
screen.
• Restore backed-up files to your Windows
environment or the entire contents of your hard disk
to its original factory contents using the Lenovo
OneKey Recovery system. If you still see only the
cursor on the screen, have the computer serviced.
