I don't know what your level of expertise is, so forgive me if this gets simplistic. Were ''any'' of these problems showing up before you changed the hard drive? If not, then the answer is probably with the keyboard - either it is defective or not properly seated. Have you tried using an external keyboard? Also, check the keyboard socket on the logic board for any evidence of breakage, scorching, corrosion or verdigris that is often left behind by liquid damage. If there's damage, then, yes, you've got a logic board problem. :-( Light corrosion ''may''be removable with a soft bristled toothbrush. When does the kernal panic occur? If consistently on start up, then you may have to simply format and reinstall the OS on your hard drive. Also, make sure that you are using an OS that your Mac can handle. Bad RAM or badly seated RAM can cause kernal panic. Try reseating the RAM, or removing one stick of RAM, or using known good RAM, and see if the problem is resolved. It can be tedious, I know, but if all of the above fails, try removing internal devices from the logic board - one at a time, and see if the problem persists. Disconnect the airport card, bluetooth, the optical drive, the keyboard, etc. If you remove the keyboard, you will have to start the laptop by shorting the power-on pads that are on the logic board. They can be a bugger to find and are not in the same place from model to model. Just look for two tiny pads with the letters PWR. Use a flat blade screwdriver to make the connection between the two. Hope some of this helps!
