Hello,
I am trying to use the lid switch on my ibm r40e thinkpad laptop to automaticlly put the laptop into standby and bring it out of standby. I want to hook it up so that when power is supplied (the car is on) then the laptop thinks the lid is open and when power is not available the laptop thinks the lid is closed.
I have a multimeter but there are six leads into the switch on the mobo as far as I can tell so I was wondering if anyone could help me figure out what to measure? Here are a couple links to some pictures of the switch. I apologize for their quality.

http://students.engr.ncsu.edu/ans/pics/im2 better focus but can't see all the leads
Once I have measured what is needed then I will also need some help determined what circuitry I need to make it work. Also if there is a kind of solder that I should be using for this. Right now I have Rosin-core solder.
Thanks a lot,
Paul
