I just bought a Predator Triton 500 for college about a day ago and everything was fine when I would plug it in and unplug it. However, about 6 hours after purchasing it the laptop made a single beep noise when I plugged it in and unplugged it and the beep is still happening. Is there something wrong with the laptop or is this some kind of error. The battery does charge normally and other than the beep and some coil whine, the computer is working fine. Does anyone know if this can be fixed?
