Hi all
I have one of those machines. Clevo PC70DP.
Machine starts, but turns off quite quick. Just before turning off one can hear fans are spinning at high speed. Can be turned back on again right away.
So, feels like overheat problem.
I cleaned up fans and heatsinks and replaced thermal paste. I can now see CPU runs cooler and machine stays on for longer, but still same.
Few more findings:
1. on-board NVIDIA card is not found. Not showing up in Windows or in BIOS.
2. I tried to run CPU stress test. CPU stays at about 65 degrees. Works OK
3. Looked at the board with thermal camera. "hotspots" are CPU, multi IO chip and M2 drive.
Machine works OK, running just one fan on CPU side. Then it would suddenly (just idling in Windows) turn on both fans on high speed and turn itself off a minute later. At this time, thermal camera is not showing any changes in temperature of the components and no new "hotspots".
To me it feels like a "runaway" temperature sensor telling CPU it is overheating and machine turns itself off. The fact NVIDIA chip is not detected makes me think it is probably a GPU sensor.
I think, NVIDIA problem is a primary source of issues, sou would appreciate any advice.
