this is driving me a little bonkers. came home and found the macbook pro powered off in its vertical dock. no logs. so i don't think it was power. random crash, i guess. random crashes can be power related less likely on a laptop i suppose hoping it was a one off do macs crash much? i had a weird linux GPU crash the other day. it just seemed to abort most X programs. ] radeon 0000:01:00.0: GPU fault detected: 146 0x0b892014 i see the problem > radeon wasn't much choice before if wanting dual head with high res. now onboard video with displayport seems to be able to do 1440p/4k but i've basically got the best fanless video card - radeon 7750 would rather more ram though. it's only 1gb hmm i've had some more GPU fault detected, but haven't even noticed
