my neighbor dropped his r15-100 off asking me if i could take a look at it... when i plug it in, the harddrive spins up, but the power button does not turn the unit on. i've opened the front panel and the box making sure everything is connected and the button is making contact with the board that actually has the internal buttons (behind the outside buttons).. everything appears to be fine. anyone have an idea as to what i could do/try next?
