Ok... so I started seeing the "Remote Battery Low" message on the screen a few weeks ago... not all the time, just if I was pressing several keys in succession for something. So I went out and bought some new batteries (had no AAA in the house). Before taking out the batteries, I paused my live TV so I wouldn't miss anything while I was fumbling with the remote. I took out the batteries and disposed of them... and then just on a lark, decided to point it at the TV (no batteries inside) and unpause the TV. Sure enough, it unpaused. Try this with your friends and impress them with the remote that requires no batteries! Ok.. so I know technically why that worked with no batteries. Just enough residual charge, probably in a capacitor somewhere, to allow one keypress after the batteries were removed. That didn't surprise me. What did surprise me... No low battery message on the screen! With batteries inside, I got the message... without batteries and running on residual charge no message. Curious.. made me wonder just how accurate that message was after all.
