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.
