Just brainstorming here -- If your laptop has a "wake on ring"  
feature in its BIOS, you might be able to interface that device to  
the serial port and avoid opening up the machine.  I think you'd just  
have to pull the RI (ring indicator) pin high.  This is pin 9 on a  
DB-9 serial port.  Note that RS-232 uses negative voltages to  
indicate a logic 1, so that means applying -3 to -12 volts.  You  
could probably test it with a 9-volt battery before spending any  
money on hardware.
