Thanks for the help! I tried everything you suggested, but nothing worked.

I followed all the instructions. I booted my MacBook in safe mode and checked for updates. Then I ran Apple Diagnostics, and it returned the code ADP000. It says "No issues found," but the button still isn't working.

What should I do now?

Should I take it to a service center? As I understand it, just because the diagnostics didn't find anything doesn't mean there isn't a problem.

I would take it in.

In or out of warranty you can get a free over the counter 'Apple Service Diagnostics' test /assessment

Hello, everyone. I have a 16-inch 2019 MacBook Pro with an Intel Core i9 processor. I'm having a problem with the power button.

It started when I couldn't add a new fingerprint to Touch ID—the system kept giving me an error. I thought it was a software glitch.

But today, the laptop shut down, and I couldn't turn it back on using the button. I had to open the lid for it to boot up on its own.

I think it's a hardware failure. The laptop hasn't been dropped or exposed to any liquid. It only has about 100 battery cycles.

What should I do? Has anyone else experienced this? Is this covered by the warranty? Thanks.

The shutdown you did not elaborated on...(???)

A SafeBoot Start up your Mac in safe mode - Apple Support will sort many anomalies

Login and test. Reboot as normal and test. Caches get rebuilt automatically.

run the user Diagnostic...not as definitive as Apple's own AST2 (Apple Service Toolkit) back bench diagnostic, but may kick out an error code.
