Battery (?) Problem - How to test?

[SchmuFoo]

I have updated the Ticket, Thanks.

Is it still safe to use the PPM and leave it unattended? Also because of the new Bugs I have inserted at:

V1.0.32 (pre-1.1.0) now available for beta testing

(Dont want to see this Link please Outside this Beta Forum) This Happens now for the Second or third time: No Picture suddenly but Lightengine was on Fan Sounds suddenly weird / rattling No Power off via Remote possible After Shutdown via Button on the PPM everything was working again https://photos.app.goo.gl/7WmoCBysj9acQ6Sg8
