My VT200 will work fine for a couple hours but when I leave it idle for awhile, it will turn off. Only way I can get it back on is if I plug it in. After that it will be good for awhile and then turn off again. I do not think it is a fuse since it will work without the charging cable as long as I don't let it sit for awhile. It is only when I haven't used it for awhile that it will turn off. I got a new battery and it does it as well. Only thing I can think of is that I just updated to 2016 firmware when asked to in Escribe. I tried soft reset, hard reset, reset to factory settings, re applied firmware. Not sure what else to do.
