Thread: prob with power to laptop

i was at my inside friend's house messing around with my carputer and the power goes out for a second and comes back on. but, when it comes back on some parts of the house where lit and some weren't. so the laptop stays on, but the button that lights up when it's on a/c power is off, i figured it was from the power outage. when i get home and try it, the light for it being on a/c current nevers goes on, but the computer boots up, and shortly shuts off cause the battery was low. it never came back on. it sounds like it's the unit that converts 110 to 15 volts. my friend that is into computers sayd i can go to a local computer shop and have it fixed cheap or purchase one for cheap. is this the case? i tried taking it apart, but it is sealed by metal after the plastic covering came off. should i just go to a comp shop and get it fixed tomorrow? need to get it done by tues. thanks
