I bought this as a gift for a very close friend and the keyboard didnt work in any ports.  I am now having to contact Acer tech support.  I hope they can help me help my firend.  She was using an old Samsung all in one. This was a major upgrade for her and it hasnt worked properly since day 1.  I should have had her return the whole thing instead of just the key board.  She also had trouble with the hdmi ports but think she finally got that straightened out.  Yes good deal for the money but be careful with connecting items to it.  She is not a happy camper
