Just bought the 16" MBP M1Pro and noticed when I "shutdown" the MacBook, close the lid, plug in the supplied MagSafe charger to the Mac, the MagSafe indicator light flashes amber and making a connect/disconnect sound from the Mac. Now if the Mac is powered on, charging works as it should. Spoke with Apple Support on this and they have no clue on this type of issue. Anyone else experiencing this issue?
MacBook Pro (2020 and later)
I skipped on sending it in for a replacement and followed a tip I found somewhere about the "Battery Optimization" feature. Don't even really understand what its supposed to do, my comprehension skills aren't the best but I guess its supposed to help with the battery life by following your charging habits. What I took it to mean is that it wont charge my laptop when I plug it in based on some arbitrary AI trying to track my sporadic and random habits of charging.
So.... Turned that feature off and I can safely say that my laptop charges whenever I plug it in, close the lid, shut down, etc. No more blinking on and off with the charger light going on and off. Works like normal.
I did also update after receiving it, i'll assume its the 12.0.1 (I'm not on that laptop right now to check but im sure Monterey hasn't had that many updates since I got the laptop a week ago.)
Hope this helps someone out.
As per the release note, the new release MacOS 12.1 should fix this issue
Thank you for confirming the issue YellowPhrog. I have spoken to 5 Senior Advisors at Apple Support and one of them did confirm there was an issue with some very early production models.. Apple decided to replace my MacBook today so waiting for the exchange to arrive.
An update to my post...
If I leave the charger plugged in then shutdown, it does charge. Can also charge via USB-C while shutdown.
Hopefully helps anyone short-term while the issue is addressed *fingers crossed*
MacBook Pro 16-inch (2021 M1Pro) Charging Issue:
I can confirm my new MacBook Pro is exhibiting the same charging problem being reported by others. The system came with MacOS Monterey v12.0.0 but I did not perform any testing with this version of the OS. I updated to v12.0.1 and a day or two later I first noticed the problem and checked the Apple Community Boards to learn that others were experiencing the same issue.
For me, the issue only seems to happen when I shut down the system and close the cover before connecting the power adapter. When the power adapter is first connected, the orange light comes on, then I hear the “chime” indicating that charging is starting, then the light goes off completely and the cycle repeats. I have the power adapter connected to a watt meter and it only indicates a small draw of 1-2 watts during this cycling.
I also tried turning off the “Optimized battery charging” feature under System Preferences but it did not change the behavior. If I shut down the system but leave the cover open, when I attach the power adapter, the system turns on and the power adapter light is a steady orange. My power meter shows a draw of about 135 watts. If I leave the cover open and shut down the system, the power adapter light is a steady orange and my power meter continues to show a draw of about 135 watts. I even tried closing the cover at this point and charging continued.
I’m hoping Apple will be able to correct this issue without replacing the MacBook or the power adapter. Until then, I will be leaving the cover open while I charge the battery.
The answer is to turn on the laptop, plug in the charger, then wait until the orange LED lights up on the MagSafe plug, then close the lid. That works for me and I've not bothered with fiddling with the optimized charging feature. I did have the laptop open overnight, split, on its side, but then noticed that the power consumption remained at 130W when the lid was left closed (but don't forget, you have to turn on the laptop first!)
Hi All
Not sure if this will help but I contacted Apple Support on chat and they advised to put the MacBook in safemode, then boot as normal. It seems to have resolved the issue. Will test further when the battery is below 20%.
You have camped-on at page 6 of a six-page thread on this issue.
The current work-around is to connect the charger before you close the lid or shut down.
Totally agree! I just received my replacement today and out-of-the-box it performs normal under macOS 12.0. When I updated to 12.0.1, the issue re-appeared. Sounds like it to me it's OS/firmware related and not hardware. I'm sure Apple is aware of the situation and a fix will be released in future OS updates. In the meantime enjoy your new book!
I own a new 16 inch M1 Max 64GB and have the same issue on Monterey 12.0.1.
Having read through this thread, and others around the web, I've now read quite a few posts from people who have received a new machine, and found charging is fine on 12.0.0 but the issue returns on 12.0.1.
I've had my machine for just over a week now and I don't recall having charging issues out the box (on 12.0.0) but I definitely have them now, on 12.0.1.
As suggested, I have reported the issue to Apple via their feedback site: www.apple.com/feedback
Update on my own situation (original reply here).
I spoke to Apple online chat who - after having me explain everything in meticulous detail - linked me to an Apple article suggesting I make sure the MagSafe connector and port are clean... yeah. Not impressed.
Anyway, having explained that - funnily enough - I'd already tried that (◔_◔), they scheduled a call-back with one of their next-level-up support people.
After explaining the issue to him, he has arranged for a replacement MagSafe power brick and cable to be sent to me.
I will reply to my own post again, once I receive it, to let you guys know how I get on.
I had just received a confirmation that it is a software issue. They will fix it in the future macOS. The confirmation came from the apple engineer team communicated through the apple support advisor team
I had just finished chatting with the apple advisor they recommended me to wait for the fix in the mean time
charging the Mac while in sleep mode
charge the Mac using usbc port
connect the MagSafe before turn off the machine
Has done exchange and same issue happens only after upgrade to 12.0.1. I try disabled that pwr optimization in pwr management, reset pram for the new device, doesn't work at all.
Same issue here. There's a huge thread on reddit for this issue. Seems like the replacements are doing the same thing. Hopefully that points to a software fix. Seems to be fine if a lower wattage brick is used or the battery is at a high state of charge, pointing to an issue with the fast charging perhaps.
One person on reddit claims that he did reset SMC on his/her MBP 16 M1 Pro with this instruction: https://i.imgur.com/kadWG0R.jpg and now everything works fine for him/her.
I know how it sounds (SMC on MBP 16 with M1 chip etc.) but here you have a link to relevant comment on reddit: https://www.reddit.com/r/macbook/comments/qnfwxr/comment/hken6hj/?utm_source=share&utm_medium=web2x&context=3
Just sharing as maybe somehow it works overall. I know there is no way of resetting SMC on M1 - officially.
