Ok I started a similar thread and nobody seems to know or care to answer. Here is what I think has happened. Immediately before the tablet stopped working properly I used my HDMI cable to connect to our TV so we could hopefully watch some episodes of our favorite shows. When I tried to stop on show it would not stop. The only way I could stop it was to shut down the tablet. Using the suspend/sleep function with a short tap on the power button didn't work. Since that time the sleep/wake function doesn't work. Additionally the battery life is evaporating like the unit is ON all the time - it will last less than a day once it is unhooked from the charger. BUT it still takes a cold start to get the unit on. I can't find any function control for the sleep/wake function and I wonder if that is something only accessable through a factory tech's powers.? Any ideas folks - Otherwise I have an RMA number to send this in for warranty service but from what i hear that isn't always successfull. HELP ! !
