Thinkpads have very good advanced diagnostics. If you don't have
manuals telling you how to access them, check out IBM's website (even a
google site:ibm.com ) using your machine number (the four-digit IBM
number not the sales dept's Z61M. You should be able to find the
service manual for it which will tell you how to run the advanced
diagnostics.
It is those diagnostics that IBM will run to determine a warranty claim.
The manual tells them which FRUs to swap out until the diagnostics tell
them that the machine is good.
Good luck.
Doug.

Thanks for this suggestion. I downloaded the manual but I don't have
the diagnostics program. However, the problem seems to have gone away at
present. I'll phone the UK support team on Monday and discuss it with
them.

Hi Anthony,
The diagnostics are already in the thinkpad's bios. The manual should
just tell you how to access it. Remember, its the service manuals you
want, not the customer's troubleshooting manual. You'll know you have
the right one if somewhere they tell you to change the system board,
which isn't a usual customer activity :)
For example, I have a Thinkpad 600E with a dead screen and hard drive
(lightening strike while I was using it in a tent when the tent got
hit). To run the diagnostices on it:
Press and hold F1 while powering on the computer.
Click on test to get the basic diagnostics
Run those tests
Press Ctrl-A on the basic diagnostics screen to get the Advanced
Diagnostics
Click on Exit or press Esc to go to the keyboard advanced diags.
Run those.
Click on Exit again and you get the full advanced diagnostics menu.
Select a device or select All Devices.
That's the same keystrokes (minus the mouse action) as they were on my
IBM 486, on which I needed a separate Advanced Diags. disk. I would
guess that the basic key sequence would be the same on your Thinkpad.
Good luck.
Doug.

This is the manual I got. Unfortunately, i seems that the Z61M only has
a HD diagnostic program. It tells me to download more stuff to test
other things from their download drivers site but I can't see anything
relevant there.

OK, managed to run the program down to earth (PC Doctor DOS) so I'll
see if it works for me.

Thinkpads do NMIs and SMIs for system management. It is likely something
stupid, thay you should not worry much about. Try disabling "pci bus power
saving", see if that helps. If it does, just reenable it and ignore the
warning.

I tried this but the error message still appears. However, I now have
more information.
1. It does not seem to occur with Ubuntu, only with Sid (actually,
Sidux). And not every time either; about 1 in 3.
2. I ran the PC Doctor program downloaded from the Lenovo site. This
shows no errors except for the parallel port, but this machine has no
parallel port. I've therefore disabled the parallel support in the BIOS
but I don't know if that will make any difference.
3. I rang Lenovo support, who predictably said it was a Linux problem,
not a hardware problem.
As everything else is working correctly I think I shall have to ignore
it for the moment, unless or until something else happens.
