Sprayed a paper towel with 'Glassreiniger' (I guess windex is a brand of glass cleaner?!) and wiped the keyboard thoroughly. I did the same, that i did many times with my keyboard (also USB, Numpad, but with one or two different keys, bought in 2009 or 10) and with my 2008 MacBook (Alu unibody). I have the same problem: Cleaned my parents keyboard (usb, numpad, bought in 2013/14, which was a bit scruffy after a year or so. 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. Luckily you can find many for sale in great condition and or brand new for relatively little. Great guides on how to step by step remove your keyboard can be found here: Īfter 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: If the keys still do not respond, it's time for a replacement. 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. Chances are you may have not damaged anything besides the keyboard, and that too may be repairable as well. You'll truly be suprised how even a small amount of liquid can get in and damage the keyboard, it's very common unfortunately. 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! 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? I've run diagnostic checks and it's all been passed. 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? For a while the caps lock light worked, but now has completely died and doesn't work even when pressed on the USB keyboard.

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.

However the keyboard did nothing but work a bit but the keys not doing the functions they were assigned to do. 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. Earlier I cleaned my Macbook keyboard with a wet wipe, brushed over the keys (pressing them down whilst doing so).
