External Diskette Drive Problems

The diskette drive in-use
icon on the external
diskette drive stays on. If there is a diskette in the drive, verify that:
– The external-diskette-drive connector is firmly attached to the computer.
– The diskette contains the necessary files to start the system.
– There is nothing wrong with your application program.
– There is nothing wrong with the diskette. Try a backup copy if you have
one.
– The diskette is inserted correctly (label up and metal-shutter end first) in
the diskette drive.
If the preceding items are correct, have the computer serviced.
If there is no diskette in the drive, have the computer serviced.
Problem Action
The screen is blank. Verify that:
The power cord for the external monitor is plugged into a working electrical
outlet and into the external monitor.
The external monitor is turned on and the brightness and contrast controls
are adjusted.
The signal cable for the external monitor is plugged into the external-monitor
connector on the computer. Some signal cables might not fit into the
external-monitor connector because of the connector type.
The external monitor (CRT or Both ) is selected as the display
device using the Fn key function (see page 20) or the ThinkPad Features
program (see page 29).
After verifying the preceding items, turn off the computer; then turn it on.
If the external monitor remains blank, run the display tests described in the
instructions supplied with the external monitor. If the tests show the external
display is OK, have the computer serviced.
