See if this helps-
Unplug the power adapter. Remove the battery. Plug in the power adapter. Attempt to power up.
If that doesn't work-
Power down. Remove the hard drive and CD drive, also floppy drive if you have one. Disconnect the cables to any external devices that you might have attached. Remove all of the memory cards. Replace 1 memory card in the main slot,only. This will reseat the memory card. Power back up and see if the system comes up to a BIOS screen. If not, and you have more than 1 memory card, try swapping to the other memory card. If BIOS comes up, start reinstalling each item (Hard drive first) one at a time, attempting to bring the system up after each item is installed. If the BIOS screen doesn't come up with everything disconnected, you'll need to disconnect the LCD screen (internally) and hook up an external screen. If BIOS shows up on the external monitor at this time, you have a bad LCD screen.
If nothing in this process seems to work, you probably have a bad mother board.
If you have any questions, please ask.
