I have a Lenovo T400 and I am messing around with it. I have disassembled it and realized that there is no way I can start the laptop if the keyboard is not mounted.
Is there a way to start the laptop without using the power button located on the keyboard?
P.S: I am aware of LAN wake I am more interested in a hardware hack, like maybe playing with power pins.

Re: Lenovo T400 - Start without power button
Welcome to thinkpads.com!
Three options, from my point of view, easiest to hardest:
1) Mount laptop to port replicator or docking station and use the power button on that piece of hardware
2) Hack the keyboard connector like this: http://forum.thinkpads.com/viewtopic.php?f=45&t=115525
3) Hack the docking port connector; you will need to find the correct pins to short together and/or ground
