Z61 Series Service and Troubleshooting Guide
→ 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.
If you hear 4 cycles of 4 beeps each, the Security Chip has a problem.
Have the computer serviced.
→ Reinstall your operating system, and turn on the computer. If you
still see only the pointer on the screen, have the computer serviced.
→ Your screen saver or power management may be enabled. Touch the
TrackPoint or the touch pad, or press a key to exit the screen saver, or
press the power switch to resume from standby or hibernation mode.
→ If you use a DOS application that supports only 640×480 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 enable the Screen expansion function. (The image might
still look slightly distorted.)
