WIN32K_POWER_WATCHDOG_TIMEOUT

[tdh1987]

Hi

 

Today we've just started receiving BSODs on 5 of our 25 Latitude 3510s. We've been using them for about a month without issue. I fear the rest will follow over the coming days.

 

The stop code: WIN32K_POWER_WATCHDOG_TIMEOUT

 

It occurs shortly after waking the laptop from sleep.

 

There have been no recent driver or windows updates applied to the batch of 25.

 

If you disable 'sleep' and use 'hibernate' instead everything runs as expected.

 

We're using Windows 10 LTSC 2019 Version 1809.

 

We've updated the BIOS, updated the Intel display driver and installed the latest Windows updates (from the web) to no avail.

 

Is this an isolated incident, or is anybody else experiencing issues?

 

Thanks

 

Tom

I think is an issue with Sophos Endpoint Protection. I've performed a clean boot and and after several painful hours investigation. I strongly suspect the service that is responsible for the BSOD is 'Sophos System Protection'.

 

I've logged a call with Sophos. Not sure where to go next!
