I have a 2015 15” MacBook Pro, and it randomly shuts down and won’t boot back up. I don’t know what’s causing this behaviour.
I was just browsing the web, and it shut down and won’t power on again. I plugged in the MagSafe and the light is amber and changes to green after 20min or so. That means MacBook is charging the MacBook. However, the MacBook still won’t power on.
I opened it up, and unplugged the battery and pressed the power button to drain any electricity in the motherboard. I plugged the battery cable, and it booted up fine. The MacBook worked for a couple of days, but it randomly shut down again and wouldn’t boot up. I repeated the steps again, and it worked for a few days and does it again.
This happens regardless if it’s on battery or plugged in.
A couple of days ago, while I using the MacBook while running on battery, it went to sleep and wouldn’t wake up. It said battery low, and I need to plug it in. But when I plugged the MagSafe, it booted into MacOS but it says the battery is fully charged. I checked the battery cycle, and it’s 300. I have tried NVRM/PRAM reset and SMC reset with no luck.
The MacBook randomly shuts down when I’m running MacOS, Bootcamp, or Apple’s built-in diagnostics.
I took it to Apple Store, and they ran their in-depth diagnostics, but it showed there were no faults with the MacBook. They opened it up and say no problems inside as well.
What could be causing this?
