Hello,
I have an Asus f751l, with an i5 5200u and geforce 940m. The laptop was overheating so I opened it up, cleaned the dust, and put new thermal paste on both the cpu and gpu, (I put the arctic silver ceramique 2) and the laptop now shuts down whenever I stress the gpu. I stress tested it with furmark and tried playing games. The temps are normal. the gpu sits around the 30c on idle and when it's under load it doesn't go over 70C for a laptop I think this are ok temps. the cpu sits at 35C on idle and up to 80C when stress tested (according to intel the thermal switchoff is at 105C) At first I thought I didn't apply the paste correctly so I reapplied it but the laptop kept crashing, without overheating it would just shutdown without a warning and it doesn't want to boot up for a few minutes, the gpu doesn't show any signs of dying, no screen tearing no wierd glitches or anything. So first thing I did I disconnected the battery, and run it on the charger, and vice versa, it still crashed. so then I disabled the nvidia gpu in device manager and run stress on the integrated intel graphics, but the laptop still shut down, I already reinstalled the windows updated the bios and everything just to be sure it isn't software related. Now the laptop works yesterday I watched 1080p movies for 5-6h straight with no problems but as soon I started the stress test it shutdown after few minutes. The windows event viewer is no help it just says that the shutdown was unexpected:
UPDATE: after hours and hours of tinkering with settings, and bios, and installing various drivers I just now realised that it's the cpu's fault (kind of) basically the laptop uses the same heat pipe for both gpu and the cpu, the cpu gets heated up when the gpu is stress tested and according to intel extreme tuning utility it's throttling as soon as the gpu starts heating up, it's throttleing 100% of the time usually when it was overheating it would throttle for a second or 2 and that's it. I tried to stress test the cpu for an hour or 2 and it never went above 80C (it didn't throttle) but when I start testing the gpu it almost immediately starts to throttle, the temps don't go over 60-65C before it shuts down. the event viewer gives me this error: The speed of processor 3 in group 0 is being limited by system firmware. The processor has been in this reduced performance state for 4912 seconds since the last report. So it starts throttling as soon as I start the stress test until it shutsdown.
Does anyone know what I can do in this situation?
