MacBook won't charge or run without battery
Last week, I managed to spill a (sugary) drink into the hinge on the back of my Macbook. It shut off immediately, and I removed the bottom cover, dried the machine as best I could and set it under a fan for 2 days. I continued to let the machine dry for 3 more days while I waited for the tri-wing tool needed to remove the battery. When I removed the battery, there was more residue from the spill that I cleaned up. At this point, I tried to power up the macbook (both w/ and w/out the battery) with no success.
I then got another tool (a torx screwdriver - six pointed star) to remove the hard drive and optical drive -- more residue here. I cleaned everything I could see and let it dry overnight.
This morning the macbook powered up and seemed to be fully functional, save for: I had 50% battery remaining, but it would not take a charge. I removed the battery and plugged in the magsafe connector -- no power, no light on the connector.
I have come to the conclusion that the Magsafe board was fried during the spill. My battery seems functional, although I am unable to charge it now.
My question is... should I take it into an apple store to confirm this, risking that they will notice evidence of the spill thus voiding my warranty. My lcd was also damaged - there's a halo of brightness along the bottom of the screen - but that's for another day when I decide if it's worth replacing the screen.
