Sumtimez ports r damaged.somtimes not.. just chek other devices..if done..thn chek RAM!! lil chance tht u hv lost ur laptop!
Some USB ports on Laptops are Powered, others are not. Usually the ones at the back are part of the motherboard, and so are powered. \015\012
\015\012Try and use the ones NOT at the back for simple devices like mice and keyboards, try and use iPods etc in the ports at the back of the laptop;\015\012
\015\012Otherwise, the ports themselves are damaged, and cannot be repaired (Keep coffee cups AWAY from your next laptop!)
