I just received a used W520 with Nvidia 2000M gpu. I am running W7 and thought I would do a burn in and see what I found especially since the unit seems to have taken a hit during shipping.

I ran Passmark Burn-in Std and after about 15 minutes it gave me a fail screen. The event log listed 22 times that 90C was exceeded (93C max) on one of the CPU cores. GPU stayed at about 66C.

In the event log just before the test stopped it noted "GPGPU ops for intel HD graphics family: 1163.24 billion."

It is not clear to me exactly what caused the test failure. My guess is that the high temperature errors eventually shut down the test and this message is a GPU status message? Am I correct?

To get the temp down of course I need to open it up, clean and replace cpu paste.

I am excited to have a machine that will run Sketch UP a bit quicker and cleaner but want to make sure this machine is stable before I retire the T60p.
Any other suggestions for testing before it gets put into service?

Thanks,

Yep, sounds like a classic case of BSOD due to temp caused by insufficient cooling. Reapplying thermal pasted and giving everything a good clean to ensure airflow will typically solve the problem.

Opened up the machine, blew it out and reapplied the thermal paste. Dropped temperature about 25 deg C. Also ran Furmark and it ran steady at 85C for 30 minutes.

Passed all tests. I will try Prime95 and see how it does, but looks pretty solid.
