PM_SLP_S4_L gets 3.3v when SMC_ONOFF_L is triggered and L7520 goes up to 5v and down to 0v. 3V3_S5 diode mode is all good and E1405 it's 1k the way it should be

When SMC_ONOFF_L is triggered PM_PWRBTN_L goes to 0.3v and comes back when the trigger is released. PM_PWRBTN_L sometimes stays at 1v when plugger in and I need to trigger SMC_ONOFF_L to get 3.4v and then the same thing

Also... There was corrosion on U3210, but no short. The ship was fine, but I replaced it together with C3286/C3285 and rewire on pin 18 to the caps. Sorry I didn't start with this, maybe i should've mentioned it

SMC_ONOFF_L Triggering, I checked it right away. PP3V3_S5 Diode 0.3 and 3.3v, PP3V3_SUS diode 0.4 and 3.3v PM_BATLOW_L diode 0.5 and 3.4v PCH_DSWVRMEN diode 0.78 and 2.78, while measuring on pin 2 on R1450 I got a brief fan spin and it turned off :unsure: PM_DSW_PWRGD - diode 0.7 and 3.4v...

Hi. I have this A1466 with PP5V_S4RS3 missing and also PM_SLP_S4_L missing. I have PM_SLP_SUS_L(3.3v) and PP5V_S5 5v present. I tried reflow on SMC, I replaced U7501 with no changes... No short lines all diode modes are good. I found that when plugged in only U7100 warms up to 30 degrees and...

Yes, I saw the P13. I have the JC main programmer, but I'll have to buy this one. Do I need any files from the old chips like Wifi, BT, Mac address...?

What if I find chips taken out from the same spot, will I then need a programmer, and what kind of programmer is it?

I consulted the supplier they said they should work... hmmm o_O

I found chips but the position it's not exactly the same. Mine are 8600/87/88/89/91/92 and the new ones are 86/87/91/92/93/94. Will they work ?

Thanks for the help :)

After a while when the board will heat up it refuses to show even an image. I'm suspecting the GMux or in the worst case the GPU

Once I try to go into Internet recovery it gets frozen with some colors on the World icon, and sometimes even gets frozen in Boot. The screen stay on normal and the trackpad clicks, fans are spinning normally just the screen freezes. I was doing some more testing this morning and encountered...

Hi. Background: LCD was not showing an image at all, an issue with the speaker, and also the battery was inflated. I ordered a new LCD original(just LCD) unglued the old one and tested it all the time with the new LCD. When powered on with or without battery it shows a picture, sometimes it...

Ok, thanks, I will try to find them, If not I will ask for advice

They are different, but not sure what do they mean :D

Sorry about that. Do they have to be silver like the originals and can I use from another board?

Hi. Something that I didn't mention is that the new ships are black, not silver like the original...

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

Hello. Does it make a difference that I have also replaced U9500. I will try without U9000 and U9080 from the other side maybe it will boot up DFU mode...

I removed the 2 left from the original SSD chips and I tried to restore and/or revive it just with the 4 new chips, which are probably in the wrong position and still I get the msg ''Gave up waiting for device to transition from DFU state to DFU State'' - 0xFCA(4042)
