Macbook Pro A1708 820-00840-A does not start up

09-06-2021, 02:33 PM

Hi all, i am new to troubleshooting laptops. Therefore i need some help.

I have Macbook Pro A1708 820-00840-A which does not boot anymore.

I measured a little bit around:

Usb power meter readings: 5,113V 0,327A
On the other usb port the power meter does not show anything

C3101 - 5,143V
C3100 - 2,512V
C3108 - 3,342V
C3200 - 2,508V
C3208 - 2,075V
C3201 - 0V

DIODE mode readings:
C3213, C3011 - 0,044
C3214 - 0,113

Are the diode mode readings an indicator for a short or is U3100 faulty?

Does anyone have tips for me how to proceed troubleshooting?

MacBook Pro A1708 820-00840 stuck @ 5V, no power, no charging

by EpicFix

Hey guys, I need a little help here. I have a MacBook Pro A1708 820-00840 stuck @ 5V. Started off affecting just one port but now it's affecting both. Both CD3215 ics were replaced but the issue remains. One port does a loop and the other stays at a constant 5V. Both CD3215 have 3V incoming. I checked for PP3V3_G3H @ R3000, C3100 and C3108, R3001, C3200 and C3208. The weird thing is though that the ammeter shows the current draw (5V @ 0.5A) coming out from the port as opposed to it going in. Any ideas on helping me fix this?

MacBook Pro 2018 with Activation Lock

by envym

Hi everyone!

I have a 2018 MacBook Pro (with Sequoia OS) that I've been using for years with no problem. I recently received an M2 MacBook Pro so I'm mostly using it and not the 2018 one, but since a friend of mine needs a computer, I thought I could restore my 2018 and give it brand-new-like to my friend.

I tried using the built-in tool to restore the MacBook (Settings > General > Transfer or restore > Delete) but it got stuck when trying to remove the Find Device configuration (it asked me for the password for my old Apple ID -now I use the same account but...
