This appears to be a software issue ...
I appreciate your trying to help but I think you are mistaken, plus you don't have the same type of laptop as the rest of us do you? Yours has the Quadro NVS 140M graphics correct? That is not the same system being reported with these problems and is therefore probably irrelevant to this particular issue. Another question, do you even have two sticks of RAM? That is another specific element of this issue. If you don't have two sticks of RAM then you're in the wrong place because this issue is specific to that configuration.
I have been communicating back and forth with Lenovo and doing what I can to gather information on this issue for a couple months now, and I have not seen anything that would lead me to believe it was a software issue. I could be wrong of course, but...
Just to recap some of what we have seen so far:
- There is a specific issue to the T61P with Quadro FX 570M graphics, do not confuse this with other crashing issues the T61's have had. The particular issue I speak of is crashing / locking up / BSOD's etc. while running 3D-intensive applications such as games and 3D graphics tests, 3D rendering, CAD, etc. The issue also specifically covers running 2 sticks of memory, and most users have reported the ussue when using 4 gigs of RAM. There have been a few reports of this issue with 3 + 1 gigs of RAM as well.
There have been other T61 issues such as freezing when on battery power, random power-off while doing simple tasks, etc. These cross over into other models as well and most likely are a separate issue.
- We have reports from users with this issue in Vista 64 bit, vista 32 bit, XP, and even Linux. Operating system is not a common thread.
- The issue affects people with and without Turbo Memory. Turbo memory is not a common thread. There are OTHER issues with turbo memory crashes. Do not confuse those issues with this one. You can't lump all issues together into one. Just because some turbo memory drivers are buggy doesn't mean that explains every crash, especially since several of us don't even have turbo memory and still get the crash.
- The issue completely disappears if you remove 1 stick of RAM. The crashes go away completely and the programs that were crashing before now work fine. This, combined with the problem's persistance across different OS's, tend to suggest a hardware issue.
- A clean install of Windows doesn't solve the problem. I and several others have tried that. It makes no difference. Clean install, latest drivers, etc. No difference.
- At one point I collected more specific information from several other users from different forums who were having these same issues. I stopped keeping track because the numbers have grown, there are so many of us now. Here's some information I collected. I'm not posting people's names here for privacy reasons.
Vista 32 bit, Vista 64 bit, XP 32 bit, and Linux were all on the list of operating systems having this problem.
Some of the types of ram reported with this crash:
2 x G.SKILL F2-5300CL5D-4GBSA
2 x Lenovo FRU 40y7735
2 x 2gb Crucial DDR2 667mhz RAM
2 x Lenovo 2GB (didn't know FRU)
1 2gb stick of Lenovo RAM (Hynix) + 1 2gb stick of Crucial RAM (Micron)
2 2gb sticks of OCZ DDR2 667mhz RAM
4gb Lenovo (came with laptop, didn't know FRU)
4gb Lenovo (came with laptop, didn't know FRU)
All users who reported their BIOS version had the latest one, v1.22-1.06
Many different graphics driver versions were reported, practically every version in existance including Lenovo's latest and various Laptopvideo2go versions. There wasn't a common thread for graphics driver version.
3 users reported they had turbo memory, 3 reported they didn't have it, so this wasn't a common thread.
Resolutions reported:
8 users reported no resolution found yet
2 users reported SOLVED: Sent to depot, depot replaced planar card
1 user reported SOLVED: Sent to depot, depot replaced planar card and CPU
Some of the problem descriptions given:
3D graphics programs crash, but machine passes memtest86 and PC wizard system tests. Sometimes machine powers itself off during games. Also got error "NMI: Parity check/Memory parity error"
MAYA and other 3D programs crash, but machine passes memtest86
3D graphics programs crash, but machine passes memtest86
When running workbench multisim 10.0, the system will completely power off. Machine doesn't feel like it's very hot. Machine shuts down any time it is under very heavy use.
Any 3D intensive program causes machine to crash
Any 3D intensive program causes machine to crash
Any heavy performance stress on the system causes it to crash. Problem persists with 1 1gb lenovo RAM stick + 1 2gb Lenovo RAM stick, or with 2 2gb sticks
Any heavy performance stres on the system causes random crashes, but machine passes memtest86 and PC wizard system tests
3D graphics programs crash, but machine passes memtest86 EVEN WHEN RUN OVERNIGHT
Games cause the machine to crash in both Windows and Linux
Games cause machine to crash. Also got error message "NMI: Parity check/Memory parity error"
Comments added by some users:
Most common error is "nvlddmkm.sys has stopped responding". Problem persists with 2 2gb sticks OR with 1 2gb stick and 1 1gb stick. Removing 1 stick of RAM makes problem disappear

Removing 1 stick of RAM makes problem disappear
When he contacted IBM tech support in Canada, they told him the fix was a new motherboard but he didn't want to send it in.
Removing 1 stick of RAM makes problem disappear
Removing 1 stick of RAM makes problem disappear. Machine was later repaired at depot. Depot replaced CPU and planar card, and also noted: "Bios/Embedded Controller updates prescribed on IBM support page were performced on your machine to ensure reliability and preformance efficiency"
He says after having his planar replaced, the machine works PERFECT and he can't make it crash no mattery what he tries.
Disabling PowerMizer appeared to make problems go away
Removing 1 stick of RAM makes problem disappear, ALSO running with 2 512meg sticks of Lenovo RAM makes problem disappear
Removing 1 stick of RAM makes problem disappear, ALSO running 2 1gb sticks of RAM or 1 2gb and 1 1gb stick seems to work fine
Removing 1 stick of RAM makes problem disappear
In sum, we haven't gotten anywhere, the issue is still a mystery. Did someone say Lenovo said they can't recreate the problem? Last I heard from them regarding my repair case was that their engineer ran 3DMark06 on my laptop which was having this issue, and it didn't crash, so he said "I couldn't reproduce the issue". That seemed like a somewhat half-hearted attempt, especially considering that 3DMark06 was not one of the programs that I had listed as causing me crashes. I have not heard any updates from them about testing since then, but I was assured they are trying to find the issue. I later found out this engineer was not in fact running the test on my laptop which was known to have issues. How did I know this? Because the laptop was at my house. They accidentally shipped it back to me instead of to the testing engineers. I don't know what machine he was using for testing. It is possible he was using a machine that didn't even have this issue to begin with.
I'm as hopeful as the rest of you that Lenovo will come up with a fix for this, but at the same time, we have to think about what we are going to do if they don't.
