Hey all!

 

Earlier I cleaned my Macbook keyboard with a wet wipe, brushed over the keys (pressing them down whilst doing so). Firstly when I went to go back to using my MacBook the trackpad at first decided to use right click only functions, after a bit I managed to get this working fully again. However the keyboard did nothing but work a bit but the keys not doing the functions they were assigned to do. So I rebooted and tried to login but couldn't because the keyboard wasn't functioning resulting in me having to get a USB keyboard to sign in. For a while the caps lock light worked, but now has completely died and doesn't work even when pressed on the USB keyboard. The keyboard is still active as occasionally when I go to try and use it for example a key that doesn't actually control the brightness ends up controlling the brightness?

 

I've run diagnostic checks and it's all been passed. Absolutely no idea what's going on? If I have to reinstall Lion i'm more than happy to do so but i'd rather not if I don't have to?

 

Perhaps I damaged the keyboard itself when going through all the keys pressing them down? Although it's pretty unlikely the liquid from a wet wipe could get in right? Any help would seriously be appreciated!

    You'll truly be suprised how even a small amount of liquid can get in and damage the keyboard, it's very common unfortunately. Chances are you may have not damaged anything besides the keyboard, and that too may be repairable as well. I would first remove your keyboard and cleanse it via some rubbing alcohol and let it sit in direct sunlight for at least a few days, even using a hair dryer on cold to aid in it's drying process. Great guides on how to step by step remove your keyboard can be found here: http://www.ifixit.com/Device/MacBook

     

    After you feel you've given it sufficient time to dry, re-install the keyboard and be sure to perform an SMC reset as demonstrated here: http://support.apple.com/kb/HT3964 If the keys still do not respond, it's time for a replacement. Luckily you can find many for sale in great condition and or brand new for relatively little. Remember, always make sure your battery is removed and your laptop turned off when cleaning, and squeezing that microfiber cloth as much as possible in getting rid of that excess water before applying it in the future.

     

    Good luck.

    Hey. I did the same thing. My keyboard started to spam random letters (liiikkkee 9999999dddddddddaaa). So I turned it off and now it won't start again . I've tried SMC reset, checking RAM, let it dry in a bag of rise for 3 days. Nothing...

    It was really merely MOIST... not a drip of water even. Please tell me if you found any solution.
