n/m, i need coffe

alright, figured out where R5526 is, getting 4.5 on p1 and 4.35 on p2. since I replaced the SMC and I'm still getting the exact same error, does it seem possible that the trace going from r5526 to pin7 on the SMC is gone? (for future reference, C5526 is right beside what is C5441 on the...

I can't figure out *where* r5526 is, the 820-3302 doesn't seem to have this at all. on the schematic it says "U5000.A7:10mm ", does that mean it should be right beside the SMC?

omg, I'm a certifiable retarded, misread schematic and thought drain was an _L on q1920. I'm getting 4.5V, 3.3, and 4.4v on pins 1 2 and 3, so I'm guessing since SPI_DESCRIPTOR_OVERRIDE_L is high, this fet is open when it should be closed, ie. bad fet? swapped fet, still failing test. I'm...

cleaned and swapped the SPI and the SMC from a donor board, and I'm still getting the same two errors in ASD. anything else I can check?

drain of q1920 is high, what I *think* is r1921 is fine. do you have any idea where the heck R5526 may be located? I can't find its analogue in the 3588 schematic anywhere, so I don't even know where to start looking

what I meant is that I'd like to post a cleaned dump for other people, since I couldn't find one online, but I wasn't sure if that was against the rules of the forum. I'm off for the day but I'll get back tomorrow

on a side note, cant find a dump of this BIOS that isn't through a paywal, is there a place I can post this for future people? didn't see anything in the forum rules about posting BIOS dumps

it's the vsense for 3v3_s5, pg 49 of schematics Sensor- Voltage (VR3R) -- VR 3.3v (test1) sensor test -verifies that the sensor reads within the sensor limits. ERROR - sensor is reading below the low limit.

doubtful, I am 99% sure that I cracked the seal on this originally. I'll pop the chip and scrub the ME region, yes? any idea about solving the VR3R issue?

yes, and I got Chipset (test 1) - Management Engine Presense Test -verifies the presence of the Management Engine. ERROR-not found and VR3R, which I can't physically locate because I don[t have the right brd for this board

didn't even realize there was an ASD for this pile of crap, but here we go Chipset (test 1) - Management Engine Presense Test -verifies the presence of the Management Engine. ERROR-not found and VR3R sensor is reading low. schematics has it labeled u5520, but I don't have any u5520 in my...

replace c9560

it's an 820-3588 (late 2013 imac), I'll give you a rundown on what I've done so far. I'm the first person to take a crack at this board, no liquyid damage or anything, just got dropped off stone dead. u7600 and q6970 were bad, got it up and running but SMC and audio errors. replaced u610 and...

howdy, I've been arguing with a board all day long, and I've got most of everything fixed but this SMC error. does anyone know what the difference between PFM001 or 006 or 003 is?
