    Hi there, I just got a brand new MacBook Pro Mid-2019, Dual 8-core 2.4Ghz, and no matter what I do, I cannot get the battery to charge by any method other than the power supply the Mac came with, despite information to the contrary on the web.

    I just got a new OWC Thunderbolt 3 dock, and when I plug in the USB-C cable, it recognizes it -- but the battery icon stays BLACK, and hovering says "Battery Not Charging" "Power Source: Power Adapter". I've installed the software for the dock, and still no dice.

    Additionally, I haven't been able to get it to charge with a USB-C to USB-3 adapter cable and plugging it into a wall (or any other powered USB-3 device) as I'm apparently supposed to be able to do, and I get the same message -- "Battery Not Charging".

    I was about to blame the dock, but considering this is consistent across multiple charging alternatives I'm starting to worry there's something wrong with my laptop, and that would be a major bummer.

    I've tried all the different ports, a dozen different cables and adapters, and different wall sockets in different buildings, and result is the same.

    I also tried a battery reset by holding down CNTL-SHIFT-OPTION + POWER on Shutdown, but I'm not even sure it works like that on this machine as any key seems to wake it up, and I've updated all the software.

    Any help would be greatly appreciated! This is frustrating to know it should be able to connect and charge on one cable and I'm still dealing with two!

    Thanks for your help!
    Josh

    Contact Apple and ask. You've got free telephone support, so why not use it? Or if you're close to an Apple Store, (should be plenty of them in the LA area) take it on in and have a genius look at it.

    What happens when you use the Apple USB-c cable that came with the MacBook charger on the dock and ensure no other cables are attached to the MacBook or dock?

    The USB-A charger via USB-C cable likely does not have have enough current or voltage to charge you MacBook, Or provide PD Negotiatoon (see below). You need a USB-C charger that outputs a minimum of 30 W. With 60W or 97W better.

    The issues is that the USB-C chargers and devices like your MacBook use a protocol called Power Delivery (PD) to negotiate the current and voltage the device needs vs. what the charger can provide. If these do not match up, the cable will connect and pass data, but no power is passed so your MacBook does not charge.

    Are you using the Thunderbolt cable which would have come with the dock?

    Thank you for the reply!
    I totally forgot that I got free Apple support with a new Mac so I called -- and it was absolutely useless. All they did was ask if what I was connected to was a third party device, and then they sent me some articles about stuff I'd already done. I clearly have more tech experience than either of those two people. Sigh.
    Next level will be Apple store, but I was hoping this would be a simple solution... Seems like things rarely are!

    This is GREAT information -- thank you so much!!
    I've tried plugging the Mac into the thunderbolt with NO other cables connected, and I'm getting the charging sign with the clear battery - but the charging estimate says "More Than 10 Hours" and it's only at 95% -- so still seems like something isn't working adequately... Will leave it plugged in like this and see if it's at least a positive battery flow and I'm not using more battery than it's taking in! Great to know the wattages -- I'll look out for that!!

    ****UPDATE**** Yeah, as figured, it's not getting what it wants. It's a slow drain, the battery status varies between CHARGING with more than 10 hours remaining, and BATTERY FULL, but it's gone from 95% to 93%, and just dipped to 92%, so it's not getting what it needs. Could be this workhorse battery has too much kung-fu for this dock to quell its thirst. Looks like a return. And I may just have to live with having TWO cables plugged in.

    Any other ideas welcome - thanks for your thoughts!!

    Yeah, I've used a dozen different cables of different manufactures and lengths...

    Yikes, that does not sound good. Where you doing a lot on the macbook when you read this 10 hour number?

    As an aside always be sure all of the cables you use to charge your MacBook have USB-C on both ends. That gives you some assurance, but not a guarantee, that they will perform the PD negotiation and provide some power to the MacBook.

    You did not mention which model of OWC dock you have? For example, the 2017 model only provides 60w, so yeah, issues.

    https://www.macrumors.com/review/owc-thunderbolt-3-dock/

    The newer versions are supposed to deliver 85w, which the new MPBs need.

    Thanks for the thoughts! This is the new version with up to 85w support...
    Could it be a wonky dock?

    Yes, could very well be a bad dock or bad cable, since the charger and cable that came with the machine works.

    ADD: quick scan of Amazon reviews show a number of folks getting wonky units (eg. Ports not working, loose), including one post where same symptoms as OP unit. And also at least one review got a wonky cable.

    I'm using the cable Apple sent with it, but maybe it's a wonky port. I guess I'll try and exchange to see if that's it, thank you so much for doing that research!!

    By wonky port I assume you mean the one of the dock. But, just to be thorough have you tried all the ports on the macbook with the same results?

    Yeah, tried all the ports with different cables. No dice.
    Thanks for all the advice!

    Ok. I hope your dock exchange cures the problem.
