Our puppy chewed the power cord a few days ago but only part of the wire was exposed and I wrapped it with electrical tape since it didn't appear to be too serious. It really didn't look like he did much damage to it, but he may have just loosened some of the wires on the inside that I couldn't see. I'll try going to get a new power cord before calling Sony. Hopefully it's just the power supply. My battery is a piece of junk anyway. It came with the laptop and I only get about an hour of time out of it, if I'm lucky. I need to invest in a better one, so I guess this gives me an excuse
