T61p Freezing (with possible solution)

This might be useful to someone...

Symptoms: My laptop seemingly randomly froze on at least a daily basis whereby it was still responding to input but it was impossible to do anything in Vista. Neither the Start Menu or Task Manager could be opened to shutdown the machine so a hard power-off was required. Also leaving the computer for 1+ hours failed to do anything.

My Solution: I think this was being caused by ESET Smart Security. Removing this software has given me three days freeze free. Performance and Reliability Monitor indicate that ekrn.exe was crashing.

Why post here: This only happens on my Thinkpad. The same software is running on my Dell 510m with Vista without any problems. I have aso never had any problems with it on any other machine.

If this solves anyone elses problem please post here so I can feed it back to ESET.

Unlikely, we use ESS on all of our thinkpads in office, zero crashes thus far.

Thanks ryengineer, I'll give it a few more days to see if it remains freeze free and if so I'll reinstall ESS.

But are your office machines running Vista?

I was also having a lot of freezing issues with my T61 with Vista Home Premium. It would freeze up 5+ times per day but only while on battery power. As long as it was plugged in it was fine.

I initially thought it must be some software I had installed but re-loading Vista so I had a completely clean PC did not help at all. It was also inconsistent in that I might go for days without a freeze and then it would freeze constantly.

After installing every possible Lenovo software update I could find and removing and re-installing the memory, I have not had a freeze in weeks. Strangely, re-seating the memory the first time actually left my PC more unstable but for some reason, the second time seemed to make a large improvement in stability.

Yes.

I would also try memtest86 to check your ram. I had very similar symptoms on t43 with bad memory.
