We've got a Surface Pro 7+ deployed to a user that's been having this issue.
She says the same sort of thing:
"My surface is still freezing and kicking me off the connection, only now the touch screen stops working too. I've taken it out of the case, I've done the updates but it's still causing a lot of disruption to my lessons."
"It’s frozen again, won’t let me do anything. Clicked the button at the top to turn screen off and back on again (but not powered off) it’s now working."
"Tablet froze after spending pretty much the whole lesson writing on it. It would allow me to type but not write. I left it 10 mins and then it allowed me to write. It had got quite hot."
We have tried the following:
Installing any pending Windows updates
Installing the SP7+ driver pack multiple times
Adding the SuperWet group policy fix to her machine
Isolating her machine from all device group policies and slowly adding them after feedback (Seemed to be okay at first but it always came back)
Taking the case off the tablet to combat it getting hot
We had her use a different Surface Pro 7+ that was taken off the domain at one point where we were told there were no issues. This initially sparked the "Isolating her machine from group policy". Do we keep going with this or will I be wasting my time?
Any similar encounters and their troubleshooting steps would be largely appreciated - this has been going on since October last year!
