Hiya pal, and welcome to the forums.

From what I can remember on some mainboards 3 beeps means a memory problem (this does differ from board to board)

Try removing the memory and then reseat each dimm 1 at a time making sure they are firmly connected (Try rebooting with only 1 dimm at a time installed). (don't try this sitting on the carpet - as the electrical discharge could fry the dimms)

I was working on a friend's IBM laptop and when I removed parts, the laptop's display switched to the VGA port and not the LCD. I had to to hook up an external monitor via the VGA port and go into the BIOS and set the output to LCD or BOTH (VGA and LCD). I don't know if your laptop has that option, but if it does, it could be why you're not getting a display on the LCD.
