WHEA_UNCORRECTABLE_ERROR on HP Zbook Power G7

[mbdylan]

We've been having an issue with several ZBook Power G7 Mobile Workstations where they will experience a BSOD with the reason being WHEA_UNCORRECTABLE_ERROR.  The BSOD screen sits at 0% and no dump file is created. These laptops are running a custom in-house Windows 10 image and have been experiencing the issue since we initially received them, which was a few months ago now. However, not all of the laptops are experiencing the issue, and we also use the same image on other HP laptops with no issues. We've tried updating driver versions and the BIOS, ran HP hardware diagnostics, and various other steps that are suggested to troubleshot this particular WHEA error, but we've had no success in determing the cause. We've suspected faulty hardware but none of the diagnostic tests are failing. I'm just curious if anyone else has experienced a similar issue with the Zbook Power G7s and if there was a solution. Thanks!

Hi Ub6424,

My apologies for the delayed response here. The system SKU for all three of the notebooks that we looked at is 3F8A9US#ABA. Of these three, one had a BIOS version of 1.07 (HP T75 Ver. 01.07.00, 11/4/2021) and the other two had a BIOS version of 1.08 (HP T75 Ver. 01.08.00, 1/12/2022). However, we've tested various BIOS versions with these systems going all the way back to 1.05, but the issues continue to occur with all of these versions.
