Solving computer problems 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 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.) A password problem Problem: I forgot my password. Solution: If you forgot your power-on password, you must take your computer to an IBM authorized servicer or marketing representative to have the password canceled. If you forgot your hard disk password, IBM will not reset your password or recover data from the hard disk. You must take your computer to an IBM authorized servicer or an IBM marketing representative to have the hard disk drive replaced. Proof of purchase is required, and a fee will be charged for parts and service. If you forgot your supervisor password, IBM will not reset your password. You must take your computer to an IBM authorized servicer or IBM marketing representative to have the system board replaced. Proof of purchase is required, and a fee will be charged for parts and service. A power switch problem Problem: The system does not respond, and you cannot turn off the computer. 18 ThinkPad® G40 Series Service and Troubleshooting Guide
