System is not charging!

Hi @danj !

I am having the same problem as Kenny, my MacBook Pro is not charging anymore through USB-C. I tried all 4 ports, no luck.

I had been using a USB-hub for a while before it broke, does that make it more likely that some particular part on the logic-board has broken down? I only used the original Apple charger though.

The strange thing is, if I plug it in now, for a brief moment the laptop says its charging but then immediately stops charging.

Hope to hear from you!

Best,

Bram

Either your logic board needs repairs (charging logic) or your battery needs replacing.

To help isolate which you’ll need a USB-C power meter. Do you have one?

There’s a good video by Louis Rossmann where he goes through the A1707 charging circuit. He erroneously replaced the TI 3215 chip only to find out it was a bad capacitor (as I recall). Here’s the video: https://www.youtube.com/watch?v=G1pSqm97...

Now I’m going down that path on my third battery that isn’t charging and have a USB-C meter showing 20v at the USB-C port which quickly goes from around 1.5a to 0a. I’m puzzled as this isn’t the same behavior that Louis Rossmann describes in either of his vids. I may have to send it his way.

Ok took my MB Pro A1707 to RossMannGroup in Manhattan last Thursday. They emailed me today saying it was ready. Evidently one or more of the wires to the battery com cable connector on the motherboard. This is evidently a rather prone area and likely due to poor workmanship on the board assembly. There wasn’t any trauma or damage to this area. The solder/wire connection was faulty.

So MB Pro now back and running with the third battery from Amazon.

I’m not sure if the other batteries were good or not since this battery definitely behaved differently than the other ones.

Definitely recommend RossMannGroup.com for their quick work at a reasonable price.

So, check this connector on the motherboard. You’ll have to remove the motherboard to get to the underside where it is soldered. Check each pin of the 4 pin plug to ensure they are live.

First pic is of the swollen batteries and the com connector.

This is a close up of the battery com connector.

I have a 2017 15” Macbook Pro (don’t know if it’s A1707) with charging issues. After the USB ports all went south (finally!) Apple agreed to replace the logic board. Also replaced was the keyboard and battery. With this refurbished computer, first I experienced the battery-not-charging issue even though it’s plugged in and running off the AC power. Eventually, after fiddling around for circa 30 minutes, and the battery down below 90%, and still plugged in, it cured itself! This seems to happen about once a week, with the Apple charger or one from Milpow. Next when I plugged the power into the right-rear USB it boop-boop-booped … with power on-off-on-off-on… I unplugged and plugged into all three other USB ports, and they were fine. This boop-boop-boop… condition freaked me out before and lead me to taking my Mac in for the eventual logic board replacement. Now I’m freaking out again!
