If you do not find your problem here, see Chapter 2. The following section only
describes problems that might negate the need to refer to the more
comprehensive information in Chapter 2.
Display problems
When I turn on the compu-
ter, nothing appears on the
screen. • If the screen is blank, make sure that:
- The battery is installed correctly.
- 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 again for confirmation.)
- The memory is installed correctly.
• 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 the original factory contents using OneKey
Recovery. If you still see only the cursor on the
screen, have the computer serviced.
