Sudden Thermal Error

HP Recommended
Elitebook 840 G6
Microsoft Windows 10 (64-bit)

My EliteBook got forcefully hybernated, supposedly due to overheat. The notebook standing on my desk, so should have enough ventilation.

At startup, the notebook shows a BIOS message that something was wrong with HPSureRun.

Could there something wrong with the HW?

 

Update: it happend again.

 

Event Viewer entries:

Problem happens every 2 hours although laptop is under no load and feels it has normal temperature.

https://h30434.www3.hp.com/t5/Notebook-Operating-System-and-Recovery/HP-ZBook-15u-G6-hibernates-due-...     describes the same problem. User solved that by downgrading BIOS again.  Is there a supported way to do a downgrade?

Downgrading several versions of BIOS didn't help. Unfortunately I could go back to the previously installed version as it's not possible to downgrade when a USB-C driver dwongrade was packaged in the BIOS update.

Looks like the problem was finally solved by deinstalling HP Sure Run and reinstaling the latest version again. Laptop is now running stable for days.   Will monitor and report about the progress

Update after one month at 8th July: Laptop still runs without hibernating. 👍
