Hiya, so I've had this G752VM (i7 6700HQ) for a few years now and had to replace the CPU fan before, this was about a year or so ago. I just did a fresh OS install and in the middle of the night my laptop just shuts off unexpected. Windows reports:
"The previous system shutdown at 1:45:22 AM on 10/13/2020 was unexpected."
"The speed of processor 2 in group 0 is being limited by system firmware. The processor has been in this reduced performance state for 1 seconds since the last report."
There is 7 other warnings for the above message but for processor 5,3,7,1,4,6,0 in that order.
I have never run into this issue before with my laptop but starting to investigate to see if I can't find the issue, my temps for the CPU average around 44C at idle and nothing but windows running and maybe a few background task. The GPU sits at 43C at idle no load. I know this is a laptop but still this seems higher then normal to me, so I ran up and overridden the fans to 100%, what is tripping me out is that they seem to randomly drop speed and at times spike to a really high RPM. I can feel air coming from both fans on the back side of the laptop so the fans are running. I also see random spikes to max RPM for a very short period at idle load.
Just curious is anyone knows how to further troubleshoot this, or if I should just do a complete tear down, air blow/clean and redo the thermal paste on the GPU/CPU heatsinks (still original factory paste, "Arctic Alumina" on hand :)? Also why am I seeing drops in the fan speed at 100% fan speed?
