Just an update. I got both laptops working, thank you very much for taking time to help me work out the problem and a solution. I have also been able to repair other laptops using diode mode. didnt realise how helpful it is. Thanks

Good news. I checked the touch pad again and found a few pins that got slightly bent from been pushed in and out so many times I fixed them up and now it is working without that capacitor! Will this cause damage to the computer if I continue to use it like it is ?

Tries, didnt work. but there is a resistor near it, I'm wondering if it went with the cap. Any idea where I can find a schamatics for the track pad?

Here is touch pad details.

Update. I found the problem with the touch pad pin that was short to ground. there is a cap ( C2 ) that turned into a wire. I can not find the value for it, do you have any idea how I can find the value to replace it. or is it a cap that can be left off? It's on the touch pad it self, doesnt...
