Andreas, is it you again?
Take a look at the scheme man, I have the feeling that you still see it as a sheet of musical notation with musical symbols on it.
You are already an old member of the forum, and still asking rookie question, like the caps value and so on.
Don't take offense of course, I'm just joking here.

You mean the PU4103 ?
That's the only component where 3 and 5v are meeting.

Of course, that's exactly what he means, see the LDO 3.3v and 5v lines at the TPS51123 - VREG3 and VREG5, then push check 3D3V_PWR and 5V_PWR, check the resistance to ground at those lines too, check main power rail, check resistance and voltage at pin 8 of the bios chip and so on, all the basic checks first ...

Edit: And don't short anything with the probes or the tweezers...

To be honest it looks like musical notation to me, i never had interest in learning schematics and i still hate them, that's why i'm here asking for your help and donate to forum : ))

I'll be back with the measurements, thank you!
