Dell Laptop CPi Lid switch

I would appreciated it very much if someone can point me to
a method to disable the lid switch on Dell CPi laptop.

Here is what I am doing:
I have application that require the laptop to power-up automatically every morning at 6am. Through the BOIS, I was able to configure it without much problem. The real problem that I have is with the lid switch. The laptop would not power-up when the lid is closed. I have openned the laptop case and cannot find the lid switch. In other laptops, there is normally a small stick out switch part that get push down as the lid is closing. But, it seems Dell does not use this method.

Thank you
