earlier today i was using my gateway (read, ultimate crap) laptop on plug power, as always (i like to save battery for car and plane) and it worked fine, as always. i packed it up to bring it to new york, try to turn it on here - and it wont. the outlet is not the problem - the plug has that little green light that shows it's receiving electrical power. but when i push the power button on the laptop, nothing happens. even with the battery inside, it does not show that the plug is attached. what do i do to make my power cord work again? im scared to even use it on battery power bc it wont recharge!
