Okay, so, after a day of searching for a solution MacBook finally turned on.Īctually I do not have any special solution for this, I can only explain what were the trials. Soo look's like I need to get replacement. I've checked that wire and adaptor are working, because they were able to charge another MacBook Pro 16 but with a little different configuration (A1990) I can see keyboard lit and battery icon on screen for about 10 sec and then it's turning off.
It wasn't charged which is strange for Apple product - usually you expect it to turn on right out of the box.Īnd now it was trying to charge for almost 24h but it still won't launch. Just unpackaged fresh MacBook Pro 16 (model a2141, MVVL2RU/A, 2.6GHz 6C / 16GB,AMD Radeon Pro 5300M 4GB / 512GB). I'm a remote developer and my company sent to me a new machine. I still have a 15 day return window on the machine so I plan on running the battery down to zero to see if this issue comes up again. Plugged in the AC power while this screen in #2 was on. This resulted in the screen showing the red battery, lighting bolt, and AC plug icon (for about 5 seconds). Hold down Control, Option, and Command without the AC power plugged in for 5-7 seconds. Went to check the batter in info right away, and the machine only had 6 battery cycles on it. When I went to try this again, I got the Apple logo and the boot up bar on my screen, and the machine proceeded to start up normally. I then heard the familiar “boop” sound (which I never heard before). I then tried plugging in the USB-C cord in after holding down these three keys, while the red battery/lighting bolt/AC plug icons were on the screen. It was the red battery logo with the lighting bolt, but then it would also have the little AC plug icon next to it. I then randomly noticed that holding down Control, Option, and Command without the charger plugged in gave me a slightly different screen. Tried resetting the PRAM, and then tried Artem’s method.
I had the exact same screen that others in this thread did. I bought a refurbed 16" i9 from Micro Center and out of the box, I couldn’t get it to boot up. Just wanted to share my potential fix of this issue.
