Just as a follow up for anyone who finds this later, I was able to use a new board to charge the battery so that I could get a backup before mucking with anything important.

Yes, it’s an 87 watt charger. There is a bad CD32 chip based on the fact that 3 out of 4 of the USB C connections cycle power. I can check those connections in your post when I get home but to be clear, I’m not trying to solve that right now. I just want to be able to charge the battery without...

Just touching base on this. The only idea I’ve come up with is to get another logic board that I could use to charge the battery and then switch the old one back in once it’s charged.

But using the original block with the meter was really important to isolating the problem chip. All but one do the cycling behavior that the other posts say means those are good.

“Be sure to use original” - oh yeah. I’ve done that. I tried with multiple MacBook chargers. I took her apart and found some corrosion near the vents and brushed that out so as far as I can tell, everything looks clean. But still getting the 5v 20ma reading.

Gotcha! Thanks for the pointer. 820-00928-04. I didn’t realize there’d be two numbers starting with the same 3 digits and when I found that one I was like, “aha! This must be it!” And it wasn’t 😅

Edit: I had the wrong value. See @2informaticos post below. ——— original message below——- For anyone who finds this post later, it’s under the battery clip. (search: where is the mlb number on my MacBook Pro) My value is 820-01190-01

I suppose I should also mention that I’m getting 5v, 0.020ma, and around 300 ohms on the reader. Based on all of the videos I’ve seen so far, there is an issue with the charging circuitry which is why I was wondering if there was a simple way to bypass

Hi! Thanks :) I’m trying to figure out where I find that value but after scouring Google and the back of my logic board for the last five minutes I’m getting nowhere. Any tips on where it would be? I’ll keep looking

I have an a1707 that was working fine until the battery got low and I went to plug it in and it wouldn’t charge. It slowed to a crawl, I tried a restart, it went through a couple of instances of the fan cycling and now just shows the charging indicator on the screen if holding a button down...
