The unit has worked well for the last 2-3 years but it will not power on anymore. When u push the power button the lights come on for less then a second and then its dead again. The fan doesn't start and there are no noises. I tried disconnecting the display, reseating the ram and the harddrive but still nothing. The LED by the CAPs and Num lock don't light up at all when u try to power it up so no error message to go by. Any suggestion would be appreciated.
