hi all, wondering someone could give me advise on what to do, bought the new AO722 from USA, currently living in the UK, my netbook does not power on just on the battery when i have fully charged it and taken out the AC adaptor. it only powers on after being left for like 4-5 hours. when its fully charged and i power it, the power light comes on just for a second or two then, nothing appears on screen. this is really frustrating, have flashed to the latest bios but no luck. cheers
