Chosen Solution
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
abhiminhas the power-on pads are located right next to touchpad connector. They are labelled as R5016
The power pads are just to the left of the keyboard and mouse connector, there should also be a small power logo next to it.
abhiminhas - The first gen systems only had a SATA I (1.5 Gb/s) HD port. So you should double check your SSD if it supports this slower speed. Most today are either fixed SATA III (6.0 Gb/s) or if they support multiple speeds only offer SATA II (3.0 Gb/s) & SATA III (6.0 Gb/s) support. The Samsung 850 EVO was one of the exceptions as it offers support for all three SATA speeds. You might want to double check what you have for your system (see links above) and your SSD spec sheet.
