well, i manage to pinpoint the most likely cause now and its the display adapter (GPU), having both and even only one of them (dedicated Nvidia & integrated Intel GPU) running will trigger shutting down as if the power turned off and it restart on its own. Found this out when i try to enable the display adapters via Device Manager in Safe Mode and holy heck, Safe Mode crash for the first time.
The steps i've taken so far but been rendered well, ineffective:
- cleaned the fan and reapplied thermal paste
- system restore to two different points
- updated the driver for both Nvidia and Intel integrated GPU
- the suggestions posted in the above thread
- updating the BIOS failed, stuck at EZ flash and it just wont load
Still think this is hardware/software problem not sure anymore, afraid if factory reset mana tau actually hardware issue and in the process the shutdown trigger, even though so far the crash only happen within windows/logon screen whenever im doing something. leaving idle no problem
Maybe im just waiting confirmation from others at this point X.X
Laptop stays shutting down unless i disable GPU
