i dont get pp3v3_sus i do get pm_batlow_L, and PCH_intruder_l is present. the other two are not

I have an 820-00923 that is missing pm_slp_s5_L. I have 3.3v on s5_pwrgd. 740k ohms to ground on pm_slp_s5_L

I have an 820-00923 that ive been working on. the top side is covered in corrosion from a liquid spill. Started out only getting 5v from the charger, there was a burned trace between the test point and the enable pin to enable pp3v3_g3h, ran a wire got that working. getting 20v from charger, had...

i tried drilling the hole, inside the bigger hole i can see where the layers are visibly black and there is cavity, in order to drill out the cavity the hole would impact surrounding components. this board is dead, thanks for the help with everything

also now with both caps removed its still drawing 5a at 2v, but Ive covered the whole board in alcohol and i didnt find a single hot spot anywhere

yeah that cap is gone theres a litteral hole in the board under where the ppbus_g3h pad was, it goes all the way through to the other side, right on the other side of the board is another cap on that same line, i can see through the board now with both caps off. Both lines are still shorted to...

i injected at pin 8 of q3200 on ppdcin_g3h, i used the alcohol method and the only place getting hot was the ppbus_g3h cap CB701

was taking 5 amps at 2v

looks like it was an internal board short. shorted under the ppbus_g3h cap by ub700

I ordered a power supply, should be here tuesday and ill inject voltage then

im getting 73k ohms between ppbus_g3h and the coil. is there anything else i can check? or is my next step having to inject voltage?

I was removing caps before i took off r7020 that was my bad L7030 is around 500k ohms to ground on both sides im not sure why I got that messed up reading the first time im getting about 1.5 ohms to ground on f7000, all big coils around the cpu are between 2-5 ohms to ground I dont have a bench...

short is on the ppdcin_g3h side of r7020

removed r7020, q7030 and u7000 also removed all caps on ppdcin_g3h_chgr still have 1 ohm to ground on ppdcin_g3h 1 ohm to ground on f7000 16k ohms to ground on pin 1 L7030 (tba_phase1) 456k ohms to ground on pin 2 of L7030 (tba_phase2)

I have a 13 inch touchbar that is drawing 5v from the charger, I have a short to ground on ppdcin_g3h, I have removed all the cd3215s all the caps on that line and even all the transistors (Q3200 ect) short remains, its a 1 ohm short and I cannot find it for the life of me
