Hi

Do not waste time.immediately call acer customer care in dubai and register a complaint with them. They will try to resolve the problem over phone, if not, then take it to lulu where u have bought and ask them to do the needfull.they will help u.Th customer care number should be available in the booklet u have received along with the laptop.In fact all worldwide customer care numbers are available in the booklet.
