Device History: Ship in repair, client stated this on his notes: The unit was working fine, it came in for a broken screen. After we replaced the broken screen, we lost functionality of the touch bar. Our next step was to replace the entire top case, with a new touch bar included. After we did...

Im having the exact same issue right now. (Ship in repair) My client stated that he did a screen replacement. After screen replacement, he stated touchbar did not work. So when he was disconnecting flexes, he heard a chime, at which point he realized that the battery was still connected. Very...

Wait.... your advice is rehot CPU? haha It turned on when I would heat directly over mosfets (Q7130 and Q7135) Also I could apply heat on ISL. Pretty much heat anywhere in that area, would get fan spin. But when I have heated near CPU or PCH, there was no difference (when I put back U7310 and...

Thank you for the reply, I have orange light, until I depress the power button, then get, not even a quarter of a fan spin, then light shuts off, and pulsing begins

I put Phase 2 back on, as well as Q7630, then attempted SMC bypass mode, no difference. *Assuming I did SMC bypass mode correctly, as I've never done it before, what I did: Held down power button for 10 seconds, then connected MagSafe 2, then released power button two seconds later

I will try in Bypass mode, did Reball the SMC, that is what brought the light back and PPBUS back to 12.58. Prior to this, it was at 12.26

Device History: Im not entirely sure about the full history. I assume liquid damage. The original shop stated that he sent it out because it had fan spin, but no image or wasn't posting. Original shop wasn't sure which one. He sent it to another board level tech. Other board level tech could...

So I had an interesting one, and thought I’d share. 820-00165 - it came for battery not charging, powers on with charged battery When I disconnected the battery, I got fan spin for a second, then fan dying. Then fan spin for a second. On and on. (Not quarter fan spin) So I check my PPBUS...

How could I think R8168 was bad? On a wing and a prayer I guess. I saw fan spin and got excited, thinking I found my issue. I checked all the voltages going to the line, per your suggestion, with a closer eye this time, and noticed that PP1v2_S3 was 1v08 instead of the expected 1v2 (Initially...

Okay, after installing another R8168, no fan spin again

Wow thank you man. After removing the last resistor (R8168) I got fan spin! Now to put new resistors on

Hey everyone, looking for some help here; 820-00165, I’m in an S0 state, but no power. I seem to have all the S0 power rails besides vcore. I do not have ALL_SYS_PWRGD. I have checked the pins on Q8150 and are the following: VMON_Q4_BASE = 0v759 S0PGD_BJT_GND_R = 0v087 ALL_SYS_PWRGD = 0v668...

Hello, new here. So I've learned everything I know about Macbook, right here: https://boards.rossmanngroup.com/MacbookboardrepairvideosbyPROBLEMTYPE It was a very valuable tool for me, and now I cant find it. I've paid for this membership hoping it just changed to being paid, but still am...
