    MBP Keyboard won't "turn back on"
    Hi all,

    I spilled beer on my keyboard a couple of days ago, and thankfully, the only thing that is (or seems to be) broken is the keyboard. A couple of the keys don't work, and a few other ones will randomly input a character. I entered the following terminal command to disable the keyboard so I could work on an external:
    sudo kextunload /System/Library/Extensions/AppleUSBTopCase.kext/Contents/PlugIns/AppleUSBTCKeyboard.kext/

    I thought that this would re-enable it:
    sudo kextload /System/Library/Extensions/AppleUSBTopCase.kext/Contents/PlugIns/AppleUSBTCKeyboard.kext/

    But it's not working. I feel really dumb entering an administrator command without knowing how it works. Do any of you know what is going on with that command? I plan to take it to a reseller in my area to get the keyboard replaced, or I might do it myself. Do you think the reseller knows how to "restart" the keyboard?

    Restarting the computer should AFIK reenable the keyboard kext.
    Also what kind of external keyboard are you using? I don't know one external keyboard that requires that the internal is disabled.

    Restarting doesn't work. I disabled the keyboard because it would periodically type something that i didnt want and a few keys didnt work.

    It just might be that the whole internal keyboard is now broken.
    Spills usually take awhile before they become really noticeable, it might even be so bad that the computer will cease to work one of these days.

    Here's where I got the restarting bit.

    And after spilling beer on it, probably the logic board as well as it is a laptop alas. Beer is pretty corrosive, potent stuff with all that sugar in it. No comment on the advisability of drinking beer whilst using a laptop, however have a rad through this:-

    Also enter 'spilled beer' on the search engine at the top of the page and see similar problems and outcomes.
    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!
