I have very strange problem with this laptop, thought it was problematic discrete graphics chip, so I disabled it, but the problem persists and at this moment I am kinda confused what to do next, never faced such problem. Is it display (with touch) issue or motherboard issue, or perhaps bit of both?
It is worth mentioning that after disabling discrete GPU, HDMI worked ok, but CPU was stucked on 499Mhz, perhaps because battery wasn't attached.
Mainboard= 14217-1M
S/N=R90HK9QW
GPU=N16V-GM-B1
CPU=SR240-i3-5020U
