Help! Let my brand new 15" MacBook Pro's battery drain (not on purpose) and now it won't boot back up. Left it plugged in overnight and still won't boot up. Tried resetting the SMC, no good. Power brick never gets warm so I don't think it's charging at all. Of course no LED on these USB - C MacBooks to tell for sure. Any ideas?
Got a tip for us?

New MacBook Pro won't power on after battery drain

Apple Tech support, then a walk to the genius bar or a box with a computer mailed inside sent to Apple. A computer that won't start can't really be diagnosed.
+1 on the 5 second thing. Also, are you using the stock power supply and usb-c cable. Any other usb-c device to test those on, i.e. android phone. Have you given sufficient time for MBP to charge before attempting power up? I would give it 15 minutes or so just so that there is some power in the battery to ensure enough for boot up.
Yeah tried the 5 second power button trick. Stock USB - C cable and power brick. And I let it charge for over 8 hours. Tried all 4 ports for an hour each also. The power brick and the MacBook itself don't warm up at all which you think they would if it was charging. Very strange.
Huh, we just had this exact problem, except in our case, the machine was running fine, plugged in, and then just sorta started draining battery. Replugged cable, it came back up and started charging... Briefly. Then died again.
Since I have a nearby laptop that can check whether things are providing power, I've verified that the adapter is working at least well enough to provide 60W (I wouldn't expect the Dell to see the 85W mode). I also have a Dell dock that works and puts out 60W, and an OWC dock that appears to put out 45W, and all three work with the Dell, and none of them appear to make the Mac charge.
Machine originally arrived around... I think November 15? Been in pretty regular use since the 17th or so, no problems to speak of before today.

Think I saw another thread here where someone's new pro wouldn't recognize it's USB - C charger either. Think I got mine around the same time as well. Pretty frustrating all the issues these new pros are having.
I've verified all three power supplies are providing power that another machine can detect using the same cables, so I'm blaming the MBP.
It's pretty disappointing. I talked to apple support, and they asked me to verify the power light. What power light? The 2016s don't have one.
Anyway, they walked me through resetting the SMC, which in theory works without powering on the machine, and nothing changed. So I have an appointment at an Apple Store on Thursday.

Same here taking it in on Thursday. What's you specs by the way. I've got the 2.6ghz with BTO 512ssd and 460 pro. Wonder if this issue will start cropping up for more people like the graphics glitches or the boot camp speaker issue (I had that but reset the PRAM and it went away before it blew the speakers)
Only difference is the one I'm seeing the problem on is a 450, not a 460.
And I had to explain that, because the SSD is soldered onto the motherboard, if it won't power up, there's no way to make backups. You never really appreciate how crucial it is to be able to take the drive out of a machine to make backups until you have a machine where you can't.
I am so sick of Apple's crap right now. I really sorta wish they'd split into a company selling MacOS and a company selling hardware, so we can finally test all those claims about Apple's hardware being the best.

Luckily, most of the serious work is online.
But this has been a definite reminder to me that the risk of data loss is now a lot higher on Macs than it used to be.

To be fair, unless you happened to have another MBP or the OWC enclosure, there was not much you'd be able to do with the SSD after you took it out of a 2013-2015 MBP. It wasn't a standard connector.
(FWIW, it's a good idea to be proactive about backups, because that also protects your data if the MBP is stolen, flooded, or run over by a truck.)
Assuming that can directly power the SSD without needing the rest of the machine to be up, that should work, but it sure does seem like a regression in functionality.
The new MBP's are silent at boot.*EDIT* never mind, chime for power, not chime at boot. LOL, my mistake.
The thing works by removing the whole logic board from the failed machine. The Pro in the picture is a working device that the data is extracted to. Considering the logic board is out of the machine, I assume it is also powered somehow.
i have the same issue.. just dropped it off today for repair.
They didn't have it in stock for me to exchange for another.

Did they have any idea what the issue is or what action they're going to take besides "repair." Like logic board, power supply, battery?
