Was able to split the two parts of membrane, so that I could probe onto the pads inbetween, if you do this becarefull not to rip the rubber as there are tracks on it. You can then buzz out what tracks go to where, on the bottom connector, I got a friend to do it who is a soldering PRO.

You need to remove some of the keys to get the membrane to lift

Then with a bit of perciverence you can get the two halves of the membrane to split

Use a multimeter to buzz out then solder on the connector beneath.

I want to do the same thing. Can you post some picks please. How does the laptop actually come on...by applying power to the bottom connector?

Thanks

No, the computer comes on by shorting the two connectors. You must use a relay of some sort. Do not apply power.

Unfortunaltey, all the moving around of the laptop I did, the power button wires pulled off and my resolder job .. was not a success and I burned up some small chip on the mobo .. the laptop died shortly there after. I'm thinking maybe about glueing the wires onto my new laptop motherboard..
