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 and the
computer does not beep while starting up.
Note:
If you are not sure whether you heard any beeps, turn off the computer;
then turn it on again, and listen again. If you are using an external monitor,
See "Computer Screen Problems" on page 57.
If a user password is set, enter the correct password and press Enter.
If the user password prompt does not appear, the brightness level
might be set to minimum brightness. Adjust the brightness level by
pressing Fn +
If the screen still remains 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.)
