MacBook Pro (A1502 / 820-3476-A) - No orange/green light and no power
Hello again,
got an MacBook Pro from 2015, model A1502 and motherboard version 820-3476-A.
Device died over night on charger.
Currently I did the follow things:
1. Checked visuell the board, test with another MagSafe-Charger and with another DC-IN-board too
2. Measured 16,5V on PP18V5_DCIN_FUSE but 0V on ADAPTER_SENSE and 0V on PP_3V42_G3H and 0V on PPBUS_G3H but 16,5V goes to U7090
3. Because of corrosion and bad resistor values I changed these components: U7090 / C7094 / C7095 / R7095 / R7096 / L7095 / C7099 -> But further...

Macbookpro 2015 not turn on after long sleep
Greeting..
After a long sleep, my macbook pro 2015 a1502 won't turn on.
When it is charged, it can be seen that the light is green then orange, but with SMC Reset and NVRAM both cannot also solve this problem.
After I opened the bottom cover, I saw the fan spinning for a short time for about 1 second when the power button was pressed
guess what I should check first,
Oh I already have the scheme, it's just that I don't know where to start the inspection?

Macbook Pro A1502 820-4924-A - No Power/Charging Light
So Ive got a Macbook Pro here with no power or charging light.
I have taken the board out and did an inspection and found a small bit of water damage on C1267 (PP1V05_S0). Cap fell off as I cleaned the area but I dont think this is responsible for my no power or light issue, and should probably work just fine without it.
So after watching a few Louis Rossman videos and some post here with similar issues, Ive done a lot of testing and have found the following values of the main lines I think are important:
PPDCIN_G3H = 16.63V
PP18V5_DCIN_FUSE = 16.63V...

KB and Trackpad only work in safe mode - 820-4924-A Macbook Pro Late 2015 A1502
Hi all. I hope someone has come across something similar, as I am baffled.
I have a faulty logic board from a 2015 A1502 Macbook Pro Retina (820-4924-A). Some signs of liquid, but all corrosion cleaned, and several components refloated or replaced to eliminate any visually corroded areas of the board.
Machine boots fine now, but the keyboard and trackpad do not work at all when booting normally into Catalina, Big Sur, or Monterey. At the login screen, the cursor does not move at all when moving on the trackpad, and no keys on the keyboard respond on screen, however...

Good evening.
I replaced SMC on Macbook A1502.

Hey everyone,
I tried creating a bios dump of a 820-4924A macbook pro to change the serial number. I didn't verify the dump and quickly erased the chip before making sure it's a good copy and now the bios seems a bit corrupt.
Now since I wanted to write the original SN of the previous damaged board, I simply created a dump from the original motherboard and wrote it on the new motherboard's bios chip. I then remembered the whole ME region issue and now I am stuck. I tried to follow piernov's video on how to clean the ME but got confused half the way through 😅.

Macbook A1502 820-3476 No speakers?
Hello All.
Bit of a weird one that's got me stumped. I picked up a Macbook which wasn't seeing the internal SSD, I managed to repair that issue (broken trace) however the macbook speakers dont seem to work.
When you operate the volume up / down buttons the display comes up with a "no entry" sign underneath the speaker for some reason? Sound works OK using bluetooth speakers / headphones, but nothing on the inbuilt ones.
When I look in System preferences / sounds there's nothing listed as audio?
Anyone got any ideas?
