Solution: If a power-on password is set, press any key to display the
power-on password prompt, and then type the correct password and press
Enter. If the power-on password prompt does not appear, the brightness level
might be set to minimum brightness. Adjust the brightness level by pressing
the Fn+Home keys. If the screen still remains blank, make sure that:
v The battery pack is installed correctly.
v The ac adapter is connected to the computer and the power cord is plugged
into a working electrical outlet.
v The computer power is on. (Turn on the power switch again for
confirmation.)
If these items are properly set, and the screen remains blank, have the
computer serviced.
Problem: When I turn on the machine, nothing appears on the screen, but I
hear two or more beeps or a continuous beep while starting up.
Solution: If you are using Ethernet:
v Make sure that the Ethernet cable is connected firmly.
v Contact your network administrator.
If the screen is still blank, and the beeps do not stop, have the computer
serviced.
Problem: When I turn on the machine, only a white cursor appears on a
blank screen.
Solution: Reinstall your operating system, and turn on the computer. If you
still see only the cursor on the screen, have the computer serviced.
Problem: My screen goes blank while the computer is on.
Solution: Your screen saver or power management may be enabled. Move the
TrackPoint or press a key to exit the screen saver, or press the power switch to
resume from standby or hibernation.
Problem: The DOS full-screen looks smaller.
Solution: If you use a DOS application that supports only 640x480 resolution
(VGA mode), the screen image might look slightly distorted or appear smaller
than the display size. This is to maintain compatibility with other DOS
applications. To expand the screen image to the same size as the actual screen,
start the ThinkPad Configuration Program and click LCD; then select the
Screen expansion function. (The image might still look slightly distorted.)
