Acer Owner

Having trouble with my Acer A500, I have had it about a year and have only used the tablet for 3 months. When I turned the power switch on there is amber glow instead of the bright lite. There was an update that I downloaded to the tablet and after that the tablet would not function. I can turn on the tablet and all I get on the screen is the date, time, and the lock icon. I have tried to reset the tablet, however, this does not help. Could it be the Battery? I need Help!
