I guess it could be an intermittent hardware problem. I don't understand why the battery charging indicator shows its charging then stops. That is the one on the Home screen it always go's for exactly 5 cycles and then stops. Could that be normal? I went
to the window mobility center and that shows plugged in and charging, the battery shows its at 2 %. then after a minute the tablet shots down,I assume due to low battery. For the last week there has been no problem. The tablet is set to sleep after 5 hours
for both battery power and plugged in. Every time for the last week when turned on it has a 95% to 100% charge. Just today When I turned it on it was at 21% and slowly lost its charge until it shuts down.
Go figure
