i spilled couple drops of milk into my keyboard one morning but as it continued to work just fine i didn't worry about it. a few hours later i booted up again and continued working. about 15 minutes into it, the keys stopped working one by one starting from the right side. long story short, all but the keys on the very right side continue to work. however without basic keys such as delete, shift, and most importantly, return, the keyboard is pretty useless. took it apart hoping to clean keyboard front and back, which i did, with q-tips, would get it working again but no luck. works fine external keyboard. backlighting works only sporadically. i'm wondering if it's a keyboard issue or a motherboard issue. i can replace the keyboard myself but if its the motherboard, it's probably not worth the expense and labor. does anyone have any ideas how i might discover which problem it might be. my apple care long expired though they did replace the motherboard once. not sure what it would cost to have the apple store diagnose it. just started working again and cant afford to put a lot of cash into a solution. thanks.
