Lenovo ThinkPad completely freezes randomly

[nicofin]

Hi everyone,

 

I'm tearing out what's left of my hair due to issues with my Lenovo ThinkPad E14 Gen 6. The laptop is just a few months old, has Intel Core Ultra 5 125U, integrated graphics, one 16GB DDR5-5600MHz memory chip, 512GB M.2 SSD, and runs Windows 11 Pro. The problem is that maybe once a week or so, it freezes. No warning signs, no triggers, the display doesn't go blank, it just freezes, doesn't respond to anything, not even the power button, unless I press it for a few seconds. It has done this a few times during Teams conferences, so I first thought it could be related to Windows or Teams, but once I started trying to diagnose the issue, the freezing also occurred while it was booted from the USB stick and running MemTest86. I don't have the pro-version of MemTest86, so it only does four passes, but I've ran it six times, and once it froze, five times passed without problems.

 

Windows Event Viewer shows nothing abnormal, the only error message is after the reboot where the error is just that the computer didn't shutdown correctly. I've kept AIDA64 stability test running for a few hours, didn't freeze during that. Did a few hundred passes with LinX using almost the entire memory, leaving about 2GB for Windows, no errors and time and Gflops stable. No issues, and with all tests I kept HWiNFO running in the background, and temperatures remained stable at under 60 degrees C. Nothing abnormal. So far the only diagnostics/stability program that has given any kinds of errors has been OCCT. If I put the VRAM test into 100%, it gives VRAM errors, but if I keep it at the default 80%, it doesn't. This might well be due to the integrated GPU using shared memory.

 

This is my business computer so it hasn't been overclocked or tampered with in any way, and everything's (Windows, drivers, etc.) up-to-date. And as mentioned, I haven't found anything that'd trigger the freeze. The last time it happened I didn't even notice it for a while. I was passively watching a lecture using Teams, there was a 10min break, it happened to freeze during the break. I just kept wondering why the lecture doesn't continue, then noticed the clock had frozen on system tray, and then that nothing responded, so had to keep the power button pressed. And it has also frozen while running MemTest86, so it's likely not related to OS or a driver conflict. My next step is likely to try MemTest86+, which apparently can run indefinitely and not just four passes, so I could keep it running and see when it freezes, but it might be an hour, five days, or more than a week. The only thing I know is that it has happened almost ten times, so something isn't right.

 

I'd naturally really appreciate some advice on what diagnostics programs or other solutions I could try next to figure out the problem, but I'd also appreciate recommendations for stress tests that might perhaps trigger the freeze. After all, the computer's still under warranty, so although I'm obviously curious what's wrong, it would be enough for me to find a way to demonstrate that something is wrong so I could send it for warranty repair.

 

If anyone has any suggestions, I'm grateful and all ears, and if anyone wants more info or test results or something, I'll gladly provide everything. Thank you.

Any update on this ? Lately facing same issue on my Thinkpad E14 Gen 6 (Intel Core Ultra 5 125H)

It freezes up randomly but only when it is idle for long and not when it is in use.
