Hello HP Community,

Late last year I acquired a HP Probook 460 G11 Notebook.

I'm having an issue whereby it randomly crashes often when connected to either one of my universal docking stations or alternately an external monitor (with no docking station).  Sometimes it will go for hours before crashing, sometimes it'll go for an hour...

Once it crashes, the only way to resume using it is to force it to shutdown via power button & restart.

I have ensured that all drivers & the system BIOS are up to date.   Also, I have run DISM to Check & Repair the Windows Image and SFC /Scannow several times in an effort to stop this occurring.

The Event Viewer Error message I get after a crash reads as follows:

 

Failed to process session change. System.NullReferenceException: Object reference not set to an instance of an object.
at HP.Watcher.WatcherEngine.FireEnrollmentCheckIfPresent()
at hptpsmarthealthservice.hptpsmarthealthservice.OnSessionChange(SessionChangeDescription changeDescription)
at System.ServiceProcess.ServiceBase.DeferredSessionChange(Int32 eventType, Int32 sessionId)

 

Has anyone had this issue before or knows a solution?

 

Cheers.
