I have a Samsung Chromebook I think it's a V2. This just started happening recently my screen goes black but I can still swipe up and see my whole taskbar and I see notifications on the run. Sometimes I'll close and reopen and see some of the screen then it goes black again. I'll be playing my slot machine game in the screen just goes black I have to reboot it turn it off and back on. I'm out of warranty Samsung said for me to do a power washer switch I hate to do but I will if I have to. Any suggestions? I may have had an update recently I can't really remember.
