    So my spouse has a 2016 MBP, which he's basically okay with. Except that it stopped charging. The first time this happened, earlier today, reseating the power cable caused it to wake up. Now it's dead again.

    Problem: I don't have anything else that uses USB-C for power, except that my primary working laptop can optionally do that, except all it'll do with under 90W is announce that there's not enough power to run it. So I have three things that theoretically provide USB-C charging, and none of them appear to power the MBP through any port.

    But I can't tell for sure, because there's no indicator lights of any kind. The charger doesn't have one, the cable doesn't have one, the machine doesn't have one. So I can't tell the difference between "has power but needs to charge for a while before it can come on" and "doesn't have power".

    Anyone have any suggestions for ways to debug or diagnose this? Any notion what's likely at fault? If, as I sort of suspect, the problem is internal to the machine (after all, I do have three things that should be able to power it, and three different power cables, and none work), we're sorta screwed, because obviously there's no way to make backups from it, and we can't take the drive out to copy data off it...

    EDIT: So I remembered that my Dell has a BIOS setting for reporting on insufficient power from power adapters, so I tried things with it.

    Apple charger and cable: Reports 60W, which is what I'd expect.
    OWC Dock: Reports 45W. Seems low but it does show up.
    Dell dock: Works fine. (Only expect 60W with other machines, though.)

    So any of these should be enough to power the machine on, or charge its battery. Actual behavior: Nothing at all.

    You know, I really don't like the thing where Apple took away features like a charge indicator LED, or a battery status meter you can activate by pushing a button. Those were useful in situations like this.

    Yeah, I sorta figured.

    That's at least three people with this specific issue I've seen posting today, wondering when everyone got these. If it's a 3-week-in problem, there's gonna be a lot more of these threads in the next few days...

    My 15" did this last week. The OS would recognize the charger was plugged in but it wouldn't charge, it just said "Battery is not charging". Apple replaced my unit with a new one. They didn't have a fix for it.

    When the ipad does that, it's because they have super fancy stuff to determine whether or not a cable is valid, and sometimes it'll do that because they think it's a counterfeit cable or something. But usually wiggling the cable fixes it.

    Interestingly, it seemed like it recovered once when I reseated the cable in the charger. But just once, and it was temporary.

    My new 15" has stopped charging twice. It appears that the USB-C cables are really sensitive as I had a small bump of the computer knock the external HDD off-line too. When I notice the charging is an issue, I unplug and re-plug and it's fine. When I don't notice it, I come into the office in the morning to a computer that is dead due to no power and a drained battery. The joys of the bleeding edge.

    Mine will not turn on either just started about 20 minutes ago. Had it plugged in while running a game and the game lagged a bit restarted. It was Slow loading up then shut off go to check the charger it was not even hot one bit. Now it shows the red battery icon when trying to turn it on. I bought it second week of November.

    this is exactly how i discovered the issue as well. Game started lagging and realized it's not being charged.

    I don't think this is just cables being "sensitive", because I've got three different power supplies, with three different cables, and they all work 100% consistently with my Dell, and none of them work in any of the four ports on the MBP.

    Okay, if this happened to your Mac, please post when you got the Mac, and when it started doing this, and what your usual usage cycle is like. (Always plugged in, only occasionally plugged in, and so on.) I'm guessing that this is some kind of minor malfunction in the battery management. Like, it's trying to do a partial discharge, so it briefly stops accepting power, but it doesn't correctly re-enable power after the discharge, or something.

    A whole lot of these seem to be very early adopters, so November 15-17 deliveries, and here we are at December 5-6.

    Got mine on launch day.

    This is the first time it's happened. Machine slowed to a crawl. I rebooted it. Slowly powered up. Battery showed 0% and "not charging". Turned itself off and now it's just a lump >.<

    It's almost always plugged in FWIW.

    I'm very curious... which chargers did you get? I've tested the following chargers and they all work on my MBP:
    - iVoler 75W USB Type C Charger
    - Anker USB Type-C with Power Delivery 60W 5-Port Charger
    - Innergie PowerGear USB-C charger 45W

    I have the OWC USB-C dock and a Dell WD15. All three work with the MBP when it hasn't done the "stop charging" thing. Once that happened, we couldn't get anything to charge it. Have appointment at genius bar tomorrow to go look sad at them.

    Did yours ever come back on?

    I let mine charge for an hour and there was no difference. I unplugged it last night and plugged it back in this morning. Still nothing.

    It came on once for about ten minutes, never got it to work again. So, once this has happened, it appears the machine is dead permanently.

    To those who had this happen: did you use the 2-pronged mains plug on the charger, or the 3-pronged, longer cable?

    Maybe it has something to do with bad power cabling and some floating ground currents, which can damage devices when there's no ground cabling (ie when using the 2-pronged plug).

    No, we're using the 3-prong cables, and I've been running things off nice clean power.

    I'm curious. In one of the teardowns I've seen, it looks like the USB-C ports are separate boards that hook up to the main board.

    If anyone has this start happening, and has time to check: Do the ports still work at all?

    ... Although given that all four stopped working simultaneously, I doubt that's it.

    Three prong here as well. I always plug into a surge protector.
    --- Post Merged, Dec 7, 2016 ---
    Just got off of support call. Mailing the laptop back, and they'll mail me a replacement. We'll see how long that takes :-/

    All the data on the SSD will be considered lost, but I have backups of most of it.

    Irritating.

    I used the 3 prong cable and it stayed plugged in for about 85% of the time. Once it shut off left it plugged in over night and battery just drained to the point of showing the battery icon and cable. I exchanged it at the Apple Store all good now. Let me know if you guys want more details.

    I had this happen to my 15" 2016 MBP this week... received it November 15th, and it died December 19th. Apple replaced it... I sure hope this isn't a common problem that crops up after a few weeks.

    I mentioned it to a guy working the return desk at Best Buy, and he said he has seen four of the new MacBooks returned with this issue...

    Same problem as of two days ago, the machine chimes when the charger is plugged in and the battery icon in the menu shows it is charging but clicking on battery icon reveals "the battery is not charging" and "Power source: power adapter".
    I received the unit November 16th and the problem started two days ago, (December 23rd).
    I have been using the supplied power adapter and cable but used the three prong extension (from my older MacBook Pro) since I received the computer.
    I called Apple support and was walked through the procedure to re-set the SMC which had no effect. Then I emptied the cache folder in the Library to the trash, again with no change. The support tech assumed it was the charger and gave me options to get a new charger or take it in and have the charger tested.
    Since my feeling was that the charger was not the issue, I elected to take the malfunctioning MBP into the local reseller and try a brand new power adapter and cable. There was with no change in the charging issues. I shut it down and am trying to preserve the battery (it is down to ~35%) for my appointment with the Genius Bar this coming Tuesday.
    I rebooted several times in the troubleshooting process and noted the screen remained black for at least 20 seconds before I got the Apple logo.
    I routinely unplug the charger during use to let the battery run down somewhat. I have been happy with the battery life before this problem. The computer was plugged in when this problem happened as I was playing a graphics intensive game, "Firewatch". I exited the game and saw the battery level was down despite being plugged in.
    My unit is a 15 inch, space gray BTO:
    2.7GHz quad-core Intel Core i7 processor, Turbo Boost up to 3.6GHz
    • 16GB 2133MHz memory
    • 1TB PCIe-based SSD
    • Radeon Pro 460 with 4GB memory

    I had my MBP looked at in an Apple Store and testing revealed a bad cell in the battery. I'm looking at up to two weeks for it to be repaired. Not a happy camper at this point.
