HP Omen 15 - BSOD on Windows 11

[GregOmen]

Earlier this year I swapped my old laptop battery for a new one (non OEM), it involves unscrewing the back but it is relatively easy.  It ran fine.

I then updated the OS to Win 11 about a week after installing the new battery, to be honest I was perfectly happy with Win 10 but MS keep bugging me with pop ups to update to it for free so I went ahead - this was the beta version.  Once updated I started getting lots of blue screens, and to this day I still get them.   I missed the ten day time period to roll back to Windows 10, so was stuck with 11.

I have tried everything to fix it besides completely wiping my PC and starting again.  I even swapped back in my original old battery and I didn't get any blue screen for weeks, and was convinced I had fixed it, but then it started happening again!

I set up minidump to save the error log, and this worked for a while, but now even that tells me that it can't write to minidump because of an error.  I tried turning off anti-virus in case it was preventing the error log to be written, but that didn't work.

Have tried updating all latest drivers.  My BIOS is V.12 from 2020 and it seems like there should be a later one but there is no option to select Windows 11 for my model on the HP support site, just for Win10, so I just don't know.  Running "update drivers" in Device Manager suggests I have the latest BIOS.

The Event Viewer will always come up with a critical Kernel Power error (41) as the BSOD cause - "The system has rebooted without cleanly shutting down first.  This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. "

When it reboots, before it hits the BIOS I get a message saying it can't find the OS.  So I press F10 to get into the BIOS, save and then continue, and it loads the OS as normal.  I have run all the hardware diagnostics and they have all passed - RAM & SSD.  

I strongly suspect it is a power management issue.  Frequently I can get crashing when I connect up the charger, but this also happens when there is no charger connected!  It also seems to happen more when I'm watching YouTube (which is power hungry), or strangely, when I'm on Outlook.  It does not seem to happen if I'm using Word or just browsing the internet.

So I'm in a bit of a rock and hard place at the moment, I'm half thinking the update to Windows 11 and the blue screens were more of a coincidence and that in fact changing the battery to a non-OEM battery may have damaged something, and yet it can run fine for days, then decide to crash repeatedly.  Very frustrating!
