So I recently decided to install 2gb of ram and a new HDD in my Core Duo 1.8 GHZ Macbook I purchased in 2006. Put the HDD and ram in, booted up and the HDD was not recognized. Since the HDD is a Sata II drive, I removed it and put the jumper on the pins to force it into Sata 1.5 mode. Now the Macbook won't turn on. I tried putting the old drive and ram back in, battery out, those crazy key combinations, and it still won't turn on. I took the battery out again, and noticed the trackpad cable may have gotten pulled on when the HDD was removed. I am unsure if the cable is damaged. Does the trackpad cable also carry the keyboard and powerbutton signals??? I noticed that when you remove the keyboard, there is only the trackpad connector to remove. Please assist.
