first i want to make sure. does this need an 85w charger or can this work with a 60w, does the fan spin on startup or is it one that has to get hot first? i do have green light with battery and amber with no battery.

well thank you for that explanation, i will have to keep that in mind. i guess ive just been lucky so far having them work.

wow, that fixed it, can someone explain how a non working or not attached trackpad can kill the keyboard? and what all models this is a problem on.

oh, sorry i will order a new trackpad and cable. i thought the keyboard would work without a trackpad installed like it does on all the other macs i have worked on. i have it on its way and will get back with you when it arrives.

sorry its taken a few days to reply. got the new keyboard in to test. still no keys. left track pad unplugged. what do you mean by both USB lines?

also found d4611 broken off and sitting on the board. traces removed, ran jumper wires.

there was a break between r7151 and c7150 and the probe point 790 so i ran a jumper between all 3 points and it started to work. can you explain how it was still able to be bypassed by holding down the power button? and how it passed apple hardware diag? im glad you had an idea where to look and...

tried with a known good power board and cable. and already ran this threw water damage treatment. as this was water damaged, forgot to mention that

i got 12.59v on f7700

already tried that, and just tried it again, still same just turns the fan on for one second

if you try to turn it on normally the fan just spins for one second. if you hold the power button for about 5-6 seconds it turns on and runs normally. everything functions and i did an apple diag test and it passes. if you restart the machine it restarts normally. but if you shut down it wont...

do you know a 15" retina model number. as stated above i only know boards as 820-XXXX

i know the lcd works as i do have picture. im having a hard time finding the backlight ic area. is there a number on the chip i can look for?

ok that is so confusing, the schematic shows 40 pins. yet there is only 30. sorry about that. makes way more since once i noticed it didnt match up 1 0 2 0 3 5 4 4.98 5 3.33 6 3.03 7 3.03 8 0.29 9 0 10 1.66 11-27 0 28 5.01 29 5.01 30 5.02

unless im compleatly reading the diagram wrong pin isnt pin 13, 16, 19, 22, 25-27, 31-41 all connected to ground. and should read 0.

anyone know which one is last years

5v on pin one, which one is last years? sorry i only know them by the 820-xxxx currently, and that also rules out my fuse being blown..

i checked every fuse i could see. but i have no backlight, from the diag i did on it, it looks like i dont have the keyboard or lcd backlight. so im looking for f7700 any idea where that is on this board? or where to look. the customer said he spilled some water on this but i see no signs of...
