I have an 820-00923 that ive been working on. the top side is covered in corrosion from a liquid spill. Started out only getting 5v from the charger, there was a burned trace between the test point and the enable pin to enable pp3v3_g3h, ran a wire got that working. getting 20v from charger, had...
I have a 13 inch touchbar that is drawing 5v from the charger, I have a short to ground on ppdcin_g3h, I have removed all the cd3215s all the caps on that line and even all the transistors (Q3200 ect) short remains, its a 1 ohm short and I cannot find it for the life of me
I have an 820-3332 with no liquid damage, it overheated during an update that failed, I have tried two new batteries the problem persists. This only happens with the battery in. on charger only battery unconnected the computer boots and runs normally. If the battery is connected after boot the...
I have an 820-3332 that sometimes has no picture. when theres no picture I have a 27ohm short to ground on ppvcore_gpu, what are the odds its something on that line other than the gpu being dead? this computer has never had liquid damage either.
I have an 820-4924 that was liquid damaged the computer will run both off the charger and the battery just fine. When you plug in the charger with the battery plugged in it will never give a green light. with the battery unplugged it will randomly get a green light after a few times of...

I have an 820-3476, ive gotten it to get to an s0 state now but im missing cpu vcore and i have a .056 in diode mode to ground on ppvcc_s0_cpu, What are the chances my cpu is fucked
i have an 820-4924 that wont get a green light while the battery is plugged in, if you unplug the battery and plug in the charger you get a green light computer can boot ect, then if you plug the battery in while the charger is plugged in it will charge normally greenlight stays, but when the...
I have an 820-4924 with no backlight, computer does get an image backlight is just not present. im getting the 12.5v all the way up to Q7700 but not after. No short to ground after the transistor .901 in diode mode both r7702 and r7701 are reading correct resistance also I am getting 5v on pin 5...
So I have a 3437 board that i replaced the led driver on, and now i have backlight, but only half the backlight is working, one half of the screen is normal brightness but the other half is darker, is this a bad led strip or did i solder on the chip incorrectly
I have an 820-3536a that turns on now. but has an x through the battery and says "no battery detected" if i unplug the charger with the computer on, the screen goes black but the fan continues to spin until the battery is disconnected. In diode mode i get .316 on pin 1 of R5380 and R5381. R5380...
I have an 820-3536-a macbook pro retina, I get an amber light on the charger, but the computer wont turn on, I am missing pp5v_s4, pp5v_s5 is presant. board was water damaged, thanks for any help
I have a macbook air with no backlight, I get a picture but no backlight, i have no idea where to even start measuring for problems on this thing. There has been no liquid damage on this board at all. thanks for any help you can give
I have an 820-3437-a macbook air that works just fine off the charger but will not recognize the battery, I have tried a new battery but still the same result. R5380 reads 5 ohms on the board, but the correct 2k ohms off the board. I get .0034 in diode mode on the smbus_smc_5_g3_sda line. any...
I have a 2010 macbook pro with an 820-2879-b mother board and it wont turn on, I am getting a very dim green light on the charger and have traced the problem back to the acok circuit, I get all the correct voltages up to pin 1 of R7010. I get 17.09 volts on pin one but 0 on pin 2, R7010 is...
