I am using a original 85w charger, but it was the battery, with another battery it turns on, thanks again for helping us

PPBUS_G3H = Red probe on ground 0.45v Black probe on ground 2.3v Changed the C7125 (didn't work), checked the rails and OK... We got delivered new U7100s, so I changed it and get 12.52v ppbus, but something strange is happening. Fan spin but yellow light on without battery plugged in, battery...

Sorry was on hollydays 1 - 3.4v; 2 - 20v; 3 - 4.8v; 9 - 0.04v; 12 - 3.4v; 13 - 3.3v; 14 - 3.2v; 15 - 0.05v; 17 - 0.63v; 19 - 5.5v; 27 - 20v PP3V42_G3H - 3.4v

Hello it's me again... Got a board with liquid damage, it turns on with battery plugged and Yellow light. Water damage was around U7100, replaced damaged components and the U7100. U7100: DCIN 20v Pin 17/18 3ohm Pin 19/20 5ohm Pin 27/28 21ohm PPBUS_G3H diode mode ok, but 0.8v

Perfect, fan spin and picture... God bless you, I learned so much. Thanks!

Oh yeah I see the 10, sorry

Am I reading it right? Both are 0ohm resistors right?

Ok so, diode mode gives me 0.444v with positive on ground, 2.315v with negative on ground...

I'm gonna get me the schematic, board viewer it's not enough, will scavenge resistors from the donor, then I will report. This is my reading, reverse is the same, it reads something for a second then I get this...

"What is the diode mode to ground reading on PPBUS_G3H?" I get 0L reading on my multimeter, sorry I miss read... I have tested the rails and I don't see disconnects or high ohm. I see 778ohm across R7121 and 3.9khom across R7122. I'm sorry but I'm a noob so please be patient with me

Ppbus has no continuity 17/18=3ohm 19/20=4.8ohm 27/28=4.9kohm Ps: these measures were made without the u7100 being on the board

Hello I have orange light on the charger, get 20v at the u7100 DCIN, i have 1 volt on ppbus_g3h even without the u7100 on the board, don't see any short on the coils I replaced the u7100 since it was blown.
