Hello,
I have a MSI GP62-2QC laptop with a Thermal 8M2L4.5 motherboard.
When I push the powerbutton, the powerled and keyboard backlight light up for half a second, then go off.
This process repeats/loops every +/- 3 seconds.
I found out that PU9 had no power output.
When I apply 3.3v to pin 7 (POK), the system stays on, cpu warms up and fan starts spinning. But the system doesn't post, or give any display output.
I also reprogrammed the bios.
Any one have an idea what to check next ?
I attached a picture of PU9 and the datasheet.
