I believe the error is that your computer's a laptop and it either has dead battery/damaged battery. On a desktop computer it may just not be plugged in properly... Check if it is overheating. Try too feel the machine's heat while it's on. If none apply, it's probably a virus. Other then broken parts, it's probably a virus. On another PC, download and burn a new copy of Windows 7 or use your old CD if you have one and try too boot into the disk. As fast as possible, if it doesn't automatically shut down, use the repair button at start of Windows 7. If it shuts down even when it doesn't boot Windows, contact a repair company and get it fixed.
