Use this procedure as a starting point for problem identification.
1. To begin troubleshooting, perform the following steps:
a. Remove all diskettes and discs from the drives.
b. Turn off the computer and wait a few seconds.
c. Turn on any attached devices; then, turn on the computer.

or the operating system to be displayed.
Is either the Windows desktop or the first screen of your application
program displayed?

diagnostic testing is required. Go to “Running the IBM Enhanced Diagnostics
program” on page 66 and run the diagnostic programs. If you are unable to
run the diagnostic programs or if the diagnostic programs do not detect an
error, go to “Device troubleshooting charts” on page 48.
2. You have an unreadable display or an error message is displayed.
Is an error message displayed?

then return here.
Is the error message in this table?

your application program.

3. Go to “Device troubleshooting charts” on page 48. Find the symptom that best
describes the problem, and take the appropriate action. If the problem
persists, have the computer serviced.
