Hi all, my laptop is suffering from this http://support.apple.com/kb/TS4088 It happens more and more to the point it's unbearable to work. It also has the problem that 1 USB port seems to stop working time to time. I did a few search and it seems it's gonna take few days to a week for them to replace the motherboard. But I need it urgently to meet a work deadline. What's your thought? Can I politely ask them for a replacement on the spot?
