Help me find power pads on my white unibody 2009 MacBook

This is the abridged version. This was my first time opening up the mac so I didn't know that you could replace the HDD without having to open the whole *!&$!&$^ thing.

Anyways, I replaced Its HDD to SSD and initially it worked fine, but a day later, it stopped detecting the keypad/trackpad and a day after that even the power button stopped working. I need to determine if this is a problem with the keypad connector or something since this was my first time opening the mac or if the logic board is dead.

Also, Since I don't have a usb to sata connector, I had to plug in the old HDD a couple of times to copy the data. And I directly upgraded from show leopard to El Capitan on the ssd. Is it possible that this was too much to take for the logic board?

I have a 2009 white unibody core 2 duo MacBook (identifier 5,2) 2.1ghz and a removable battery.

Here's how it looks on the inside: http://imgur.com/a/XcPzH http://imgur.com/a/Q2GBY

I am pretty desperate. At this point I will swim to Alaska naked if it helps to solve this problem. Help
