Macbook Pro non-responsive, but accepting charge.
My Macbook Pro (Mid-2010) 13" unibody was not responding to the power button. After trying all of the reset combinations on the keyboard that I could find online, I tried jumping the power contacts on the logic board, but still had no response. The lights for the magsafe charger were working, as were the full charge lights. The computer would not power on regardless of being plugged in. I had also read that keyboard corrosion or open connection could be a potential problem. So, I ordered a replacement logic board and upper unibody keyboard assembly for good measure.
Since the keyboard upper assembly requires more time and seemed less likely, I replaced the logic board first and it solved the problem. There was visible corrosion on the old board, and the swap was pretty easy. Having the right tools always makes a difference. I only purchased the Pro-Tech Toolkit for this repair because I am in rural Costa Rica and it was actually cheaper to just buy these tools and have someone bring them with the parts then purchasing here.
Take everything you read on blogs with a grain of salt. Clean the device as well as possible while parts are removed.
