Pinephone not booting, always vibrating

[alexander12]

My pinephone (postmarketOS edition) was on, and working normally when it immediately turned off. It can be that the battery is flat.

When plugging in the power, the red light turns on, and the phone immediately starts vibrating without stopping. Screen remains black.

Same behavior without battery.

What can I try to resolve the issue?

Try recharging the battery, either using an external charger if you have one or just plug the phone in with the battery installed, leaving the phone turned off. If the battery won't charge up try a different battery. (I had one go bad on me, it does happen.)

Thanks for the response. Did your phone also vibrate when the battery went bad?

When I plug it in with the battery, it draws 0.25 amps, but when I plug it in without the battery it also draws 0.25 amps. When I hold the power button, the red light goes off, and it stops vibrating, but then the amp draw is 0.00 amps.

The phone has two states now
1) Being completely off
2) The red light is on, nothing on screen, vibrating all the time.

I seem to recall that I could previously boot the phone without a battery, but I'm not sure.

Could someone confirm if a working pinephone can be booted without a battery?
