Larry, Since the problem first started, and If you ran it on battery for a while; How far down did you let it go in terms of percentage, and did it go back up again when you reconnected it to AC power? I'm wondering if mine is somehow just misreading itself? (Like the meter inside it just going off or something?) Or, has my battery decided that it can't cycle any more? -----Original Message----- From: Hart Larry Sent: Sunday, October 16, 2016 6:25 PM To: Plextalk User Discussion List Subject: Re: [Plextalk] AC Adapter: No battery installed, or when off AC, 'battery level 0%' . Well Flor, as I've mentioned on this list, several months ago, I continually have similar issues. What I haven't narrowed down yet, are trying the power supply of the smaller BPP? I did get replacement batteries, which did not help. In my case the unit was rapidly going on-and-off AC, sometimes not even realizing it was connected. So, if you have a Book-Port, try its power supply on the PlexTalk.
