Diagnosing problems

If you have a problem with your computer, you can test it by using
PC-Doctor for Windows. To run PC-Doctor for Windows, do as follows:
1. Click Start.
2. Move the pointer to All Programs (in Windows other than Windows XP,
Programs) and then to PC-Doctor
3. Click PC-Doctor.
4. Choose one of the tests, from either Device Categories or Test Scripts.
Attention
Running any tests may take up to several minutes or longer. Make sure
you have time to run the entire test; do not interrupt the test while it is
running.
The System Test of the Test Scripts runs some tests of critical hardware
components, but it does not run all of the diagnostic tests in PC-Doctor for
Windows. If PC-Doctor for Windows reports that all of the tests in the System
Test have been run and that it has found no problems, consider running more
of the tests in PC-Doctor for Windows.
If you are preparing to contact IBM for support, be sure to print the test log
so that you can rapidly provide information to the help technician.

Troubleshooting

If you do not find your problem here, refer to your on-board help system,
