The laptop auto power on module really isn't bad as far as the Frankenstein factor. You drill a hole in the side of your lappy. Solder the two wires to your MB. The other end of the wires is connected to a plug. This gets connected inside the hole you drill into your lappy. The module has two wires coming from it with a male end plug. This gets plugged into your lappy's new plug. This makes it extremely easy to remove. The only other connections are a usb and +/- wires. Easy.
I recently installed mine into a new lappy so if you have any questions, I might be able to help.
