Troubleshooting
If you do not find your problem here, see Chapter 3. The following section
only describes problems that might prevent you from accessing the
comprehensive information in Chapter 3.
Display Problems
Problem:
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 42.
Solution:
If a user password is set, press any key to display the user
password prompt; then type 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. (Turn on the Power button again
for confirmation.)
If these items are properly set, and the screen remains blank,
have the computer serviced.
Problem:
When I turn on the computer, nothing appears on the screen,
but I hear two or more beeps.
Solution:
Make sure that the memory card is installed correctly. If it is, but
the screen is still blank, and you hear five beeps, have the
computer serviced.
Problem:
When I turn on the computer, only a white cursor appears on a
blank screen.
Solution:
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.
