Trying to diagnose MCE

HCorb — Fri, 09 Oct 2015 13:15:24 GMT

I am getting repeated lockups/reboots on a laptop. I'm seeing these MCE errors logged:

What hardware component is giving this error?

I have tried to update the system BIOS, which has not helped.

I have run memtest, which showed no errors.

Are there any utilities available to help troubleshoot/diagnose this issue?

The machine is a Dell Latitude D830 laptop.

It was running the A15 BIOS, but is showing the same behavior with the A17 BIOS.

I am currently running Ubuntu 14.04.3 LTS

I can boot it to Windows 7 for troubleshooting/diagnostics.

Thanks,

Harland

Also, I'm not sure what part of the MCE log is important.

I tried running the processor diagnostic tool, it reports everything is okay.

My laptop is still spontaneously locking up and rebooting.

I would contact DELL* support if you have exhausted all other possibilities.
