Macbook A1425

[iFix]

Hi. I have this A1425 with a missing PP5V_S5. I replaced U7000 and U7201 same thing. There was a moment before i did anything that it showed green light once and powered on and then it stopped. The SMC I also re-balled.

PPBUS_G3H -12.3v
PPDCIN_G3H - 15.2v
PP3V42_G3H - 3.4v
PPVRTC_G3H - 3.4v

I have replaced the SMC with another one from a different model, now I have a green light but no power and on/off triggers

Do you get 3V3_S5/SUS now?
PPBUS_G3H voltage is correct?

Be sure to use original 60/85W Magsafe 2 charger.

3V3_S5/SUS it's 0v and PPBUS_G3H is 12.6v. I am using the original 85w adapter

I ordered another SMC with exactly the same and soldered it but still same outcome green light no power PPBUS_G3H is 12.29v now

May be bad SMC, or not good soldered.
Put back original SMC.
Try to get correct PPBUS_G3H again.

Check if SMC_PM_G2_EN comes on.

I had a shorted line on P3V3S5_LL and replaced U7201 power on now all good the battery is not good and it's really slow...

 

[iFix]

I tried 2 different Bios files Clear ME and another but when i try to boot the installation it shows 5101f error... any idea ?

Machine being slow can be caused by bad battery.
You should test with known good battery.

Did you run corresponding ASD test?

We can close this case the new smc somehow burned i soldered back the old SMC and still the same. I advised client that also the battery is bad, and he didn't want to proceed, just data taken out.

Thanks
