why i cannot turn on my m1 macbook pro if there is no charger

Hi there deny64,

Thanks for reaching out to the Apple Support Communities. We understand you're unable to power on your MacBook Pro unless connected to the charger, and we'd be happy to look into what's going on.

To get started, when powering on your MacBook with the charger connected, are you able to see the current battery percentage of the MacBook?

Also, for some other troubleshooting steps visit the following links below:

• Get help with your Mac notebook battery (specifically under the "Diagnose battery issues" section)
• If your Mac doesn't turn on

Let us know if that's able to help.

Have a great day!
