Do you recommend give up and use this board for parts or keep going?

Freeze on the ASD page (ASD 3S162). I can't move the mouse or whatever. Sometimes when i plug the mouse or flash drive, the computer just shut down.

Do you have another assembly to test? If not, try use external one.

aprendiz Any more hint?

Thanks, dukefawks I thought that, but im not sure. I will replace and let you know.

Like i said before, i already fixed another rails, a mean: PPDCIN_G3H PPBUS_G3H PP3V42_G3H PP5V_S5 But i dont get: PP5V_SUS PP5V_S3 PP5V_S0 On Q7840, for example, i get 5v Pin 3 (P5SUS_SS) also pin 7 and 4. But another side, on 1 pin (PP5V_SUS), i get 0v. I think the U7200 is bad. But i'm not...

No, is not present 3v3_s5. The corrosion before is U5400 and U3890 area I dont have SMC_BATLOW_L & PM_SLP_SUS_L too.

Pin 49 and 22 i get 3.3V Trackpad and keyboard connector looks perfect

Short to ground on: - Pin 20 = 0.815M - Pin 21 = 0.836M

Yes, you are right. Pin 21 just move to 0.005 to 0.030V Pin 20 is crazy up and down

Ok, Will double check and let you know.

Update: I just get a new trackpad/cable/keyboard and still the same thing. The thing is, if i don't connect the trackpad/keyboard ans try use external mouse, the computer running REALLY slow. I can move the arrow, but like slow motion. Sometimes when i plug the external mouse, the machine just...

Replaced and works! I will test with ASD and ready to go! Thank you aprendiz and dukefawks

I just inject 1, 2 and 3v and nothing gets warm

Short to ground on VOUT: 123.6 ‎Ω

VIN PP3V3_S5 - 3.3v VOUT PP3v3_SO_FET = 2v and P3V3S0_EN - 3.3v U8030 is bad?

Are u sure about Q7830? I can't find, aprendiz
