HP Omen 17-an108nc - 3long and 2 short/memory error/ after capacitor short on 5V line

[ktmmotocross]

Hello.
I have this HP Omen 17-an108nc that show 3long and 2 short/memory error/ led blinks on Caps-lock after capacitor short on 5V line.

Come with one shorted capacitor on 5V line. After replce it just blinks memory error. i flash main and EC bios but still the same. I have all voltages on start, cpu fan spining, but onli capslock blinks and no picture

any hint?

looks like i fck up real good this time. i found ripped component on other side of board with ripped all traces. i can repair traces but i need to identify this component.

anybody know what is this?

I've come across that one before on another HP, it was a 2N7002KDW FET.

i fond ic marking K27K on HP 840 G1. by schematic it is L2N7002
Marking is K2 so looks like it is it

After ic installation laptop works but no video after restart. only work when shutdown and fresh start. maybe i put ic backwards. can somebody confirm that i put ic like i should? u update bios by windows actualization, but still the same. start till show video took about 10 seconds

weird thing is that when i try to update bios from hp page that update program tells me that there is issuficient space on disk, but i have 180GB of free space on ssd

i have been dumbaas to not look on other component. offcourse i put this ic backwards. but after rotate it, the restart problem still persist even with new bios. so i look for another ripped component

no other ripped component and schematic is not available, so i must leave it as it is. Latop works fine , ony that damn no video after restart

In the only OMEN schematic, do see that HP has dual mosfets onboard.

What is the voltage to ground of pin # 2 & #5 of this SOT23-6 package?

That may give us the confirmation / hint.
