So I got an Acer tablet (because it was the cheapest one) for school last year but ended up not needing it so all I used it for was Netflix. Unknown it's cheep it was only like $100ish but ever since I got it some thing has gone wrong. I've taking it to Best Buy at least 3 times and after a week of getting it back the keyboard attachment has stopped working. That tablet itself works fine now but why doesn't it resister the keyboard anymore? I don't think you have to charge it or anything. Or do you.
