Hi,
So, when i measured the main power rail i saw the voltage spiking between 13v to 15v so i have figured it is a voltage regulation issue
checking all related mosfet, i found another 2 N channel mosfets and another small one that got a bit of the water damage on the back of the board.
replacing it solve the issue, thanks a lot for the help!

Hi, I will only be there on sunday and i will check that.
I have found out that the laptop only works with battery connected and not charging
I am not sure if the laptop must have a working battery for it to work or it is indicating an issue
I will send the values next weekLeave a comment:

I see that the polarity of the multimeter matters when you change direction
when i probe both mosfets where black prob on drain and red probe on gate
igot 2.2M on both mosfets
what do you think?Last edited by koby058; 07-16-2025, 09:24 AM.Leave a comment:

vostro comes up with back light but no picture
Hi people!!
The owner said it showed bad picture once in a while (attached)
I see that there is back light but no picture.
I want to ask if it is possible to disable the NVIDIA GPU and use the intel one?
Also attached schematic and BDV
