Troubleshooting the Computer Screen (LCD)
Why did the computer screen (LCD) go blank?
 Your computer screen may go blank if the computer has lost power or is in a power saving mode (Standby or
Hibernate).
 Make sure the computer is plugged into a power source and is on. The power indicator on the computer will
be on if the computer is on.
 Make sure the battery is inserted properly and is charged.
 If the computer is in LCD (Video) Standby mode, press any key to activate the computer screen.

How do I change the video resolution on the TV screen?
