If you do not find your problem here, see Chapter 2. The following section only
describes problems that might prevent you from accessing the comprehensive
information in Chapter 2.
Display problems
When I turn on the computer, nothing appears on the screen.
Note:
If you are using an external monitor, see “Computer screen problems” on
page 49.
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.
