TravelMate 4650 No POST Unending Beep

[statyc]

I was given an Acer TravelMate 4650 to work on, but I have no clue where to start. As soon as it is powered on it starts to beep (no pattern just one long never ending beep) and will not show a display (display does work).

I am hoping I can find some help on what to look at

Any help would be appreciated
