Hi team,

I have the LEGION Y530-15ICH. I received the it with a sort MB (first mosfet on VGA pq5804). I changed the mosfet and the notebook works with signal.
I have in tests the notebook (Prime or Furmark) and radomly shutdown, with no power.
I installed new software and new power supply, same issue. I tested with / without battery, same issue.
Probably a problem with VGA IC (PU5801)???

I attached the schematic. Can anyone help or give any advice?

Thaks,

replace the PU5801 and it will be seen.
the video chip itself may have been damaged. because pq5804 costs 19V.
