Hi,
My laptop (HP EliteBook 8540w) freezes about once a day. When it does I have to use REISUB (very seldom I can log out with Ctrl-Alt-Delete). It happens in openSUSE and Fedora 25. When in Windows 7 it does not freeze but sometimes I get a notification that the graphic card was restarted.
I’ve read online that this laptop is very prone to overheating. The laptop does get quite hot to the touch. This is not a new problem: Last year I bought some external fans to help cooling. I’ve been using the laptop with cpupower set to the lowest governor.
I also tried switching drivers from nouveau to nvidia. It freezes less (from multiple times a day to once or none).
This morning, however, after being off for the entire night, I booted it up and it froze when it got to the GUI. The laptop was still cold… I think the graphics card is damaged for good. Any ideas?
