PPBUS_G3H and PP3V42_G3H are separate. Which one is present with no short?

Is PPBUS_G3H 8.16v or 8.5v?

Is SMC_RESET_L 3.3v, 0.5v, or 0v?

Is PP3V42_G3H present at the dc in board connector?

Is the flat cable between the dc in board and dc in cable in good condition?

 

[Aldizi]

Is PPBUS_G3H 8.16v or 8.5v? 8.15v

Is SMC_RESET_L 3.3v, 0.5v, or 0v? R5100 reading is pin 2 0.001 pin 1 3.13v resistor might be shot also just noticed u5110 looks like garbage corroded


Is PP3V42_G3H present at the dc in board connector? yes


Is the flat cable between the dc in board and dc in cable in good condition? looks good but red dot is red

You have an SMC reset issue. Replace U5110 and R5100 and clean the crap up.

 

[Aldizi]

Done. We get a fan spin. now. Pads were ripped under the u5110 is there a technique that can be used here to replace these pads when you have chips with no legs. I used a wire from cleaning wick and it worked but is there something more solid that can be done. ? cause the chip was kind of uneven.

 

[dukefawks]

Nope, just use some fine wire. You can mash it flat a little bit more, but that is just how you do this.
