do you realise that you need to have a paid up subscription in order to download files from here now?... -
Anything after 2017 will never be able to be done because of iCloud connection to Apple servers. It's impossible....Leave a comment:

you mean A3401 (820-03400) 2024 MacBook Pro 14" M4. There is no A3104 model Macbook.
Some people have posted in this thread what they say is an 820-03400, but it's not, there are no files available for that board yet.
Closest you can use is M3 820-02918 which is very similar in a lot of areas....Leave a comment:

this is now a subscription service. That is why you cannot download anything. You will need to join for a month minimum and download everything you want to avoid paying for a full year subscription.
The link in post #45 works, I just tested it. Pay the subscription and download whatever you like....Leave a comment:

thanks for the reply@mon.
PPVDD_AWAKE_GPU Actually goes from the SOC to the PMIC, so not a line from an actual GPU unless that is built into the SOC? Yes the normal diode reading as per OBData is 008 / 0ohms and on a working board there is 0.1 v On that line. on my non-booting board it is 0v. it's really hard to say that these very low resistance lines are shorted or not, but regardless there is no voltage there and with the three inductors removed on that line there is a healthy diode reading on the PMIC Side. I bought the Machine from my customer seeing as I couldn't fix it so we'll have...Leave a comment:

820-02536 not booting but close :)
M2 Air 820-02536 not booting, but charging battery 3A
No evidence of liquid damage, but I have seen cleaner boards.
on charger 20v / 0.01-0.04A on both ports
PPBUS_AON - 12v steady
PP3v8_AON - 3.8v steady
PP5v_AON - 5v steady
PP1v8_S2 - 1.8v steady
NANDs have 0.9v, 1.25v and 2.5v
no untoward heat signatures on thermal camera
I believe that these two signals are important?
PPVDD_AWAKE_ECPU - 0.9v
PPVDD_AWAKE_PCPU - 0.6V
Tried DFU restore but... -

Yes not sure if it's an 820-2098 (would have to take a close look) but it's definitely not 820-03400 is it. Boo, Hiss

you are welcome, but this is really annoying isn't it. Another board file with no schematic...Leave a comment:

Thanks for that and hopefully somebody comes up with the schematic soon....Leave a comment:

Sorry to hear that Bastien.
Message me in Badcaps and I can provide another method of contact, pretty sure that people do not want us communicating within posts here

please read through the whole post and try all download links. I already re-uploaded in post #24 and that link works (I just tested it then)

mine shows a short too 0.1 ohms but being a DDR line I would expect it to be low. I Took my reading from a locked board with one CD3217 removed, but I would not expect that to affect this reading...Leave a comment:
