Im still pretty new to board level repair, I have watched around 20+ hours of Louis's videos. So im catching on. But I still have a lot to learn. I do have a schematic and board view for this logic board.
-Looked over the board really well for liquid damage none was found.
-Tried a new keyboard/power button still no fan spin.
- I do get Green light on charger
- Tried another charger
At this point I started measuring power rails started with the main 3 Louis talks about.
ppbus_G3H - 8.4v ( I thought this was suppose to 12v, the schematic says its suppose to be 6v. im a little confused on this)
pp3v42_g3h - 3.44v
pp5v_s3 - missing 0.0v
If you can point be toward the next step that would be great.
