Hi,
I’ve got a stubborn patient here. The laptop powers on and works, all components like the screen, keyboard, touchpad, etc. are functional. The issue is that it heats up very quickly under load (within a few minutes up to 95°C) and then shuts down shortly after. Subsequent attempts to turn it back on right after a “hot shutdown” result in it shutting off within a few seconds. Interestingly, if I enter the BIOS, it can stay there for 2 days without shutting down (most likely due to low CPU load and low temperatures).
The cooling system has been cleaned, thermal paste replaced, and I’ve checked the heat pipe with a hot-air gun — it works properly. BIOS is updated to the latest available version. I suspect the solder balls under the CPU, because when I place the laptop’s motherboard on a roll of tape so that the laptop’s weight presses against the CPU heatsink, it can keep running under OCCT stress tests without shutting down, even reaching maximum temperatures. If I leave it in that position until it fully cools down and then power it on, it also boots up every time.
Memory tests are fine, the drive is fine, battery charges normally. All voltages on the coils are present and stable.
Any ideas ? Am I right to suspect that it could be the solder balls under the CPU?
