Keyboard doesn't like beer as me!

Hi all, last saturday my wife's macbook 13" drank some beer by the keyboard, we cleaned it as we could quickly, but since yesterday, the keyboard doesn't work and the capslock key light is still on. I want my wife still loving me so please can anyone could help me, note that I already disassembled many iBooks and Macbook pro.

Thanks, Boris from France

Update

I dismantled entirely to have an access to the keyboard, as shown on fixit to clean the keyboard, but it doesn't work anymore. Someone can sell me a 15" unibody keyboard, does some know if it is the same as the 13,3" ?

Thank you very much for your answers. Boris.

The caps lock light being on means the book is still powered up. Unplug it and press the power button till it goes off. Open it ASAP and get it dry.

Is it possible to access to the keyboard chipset by the motherboard ? I haven't seen a repair guide with this.

Thanks, Boris from France

Wait, do not buy the upper case. You could find a new replacement keyboard on eBay with the backlight for around $80. You do the math $80 to $250 for a non back light upper case. Just follow the instruction and you'll do fine.

If you just want to add a backlit just follow the teardown steps. Once you done the teardown your only adding two more steps.

Step 1 you'll be seeing the back of the keyboard which is cover in a black film seal with some adhesive. well there a black bracket on the center of it which supports the superdrive and the logic board. Now to remove it there's only two screws one on top and one on bottom of the bracket.

Step 2 remove the black film carefully, the edges are the only ones with adhesive. Once that's done you'll see a clear plastic underneath that is the keyboard component, but you don't have touch any of that in less your planning to replace the keyboard. If so, follow the next flew Steps***.

Now to install the backlit it replaces the black film. Make sure that the backlit ribbon is to the right of the keyboard ribbon, which is going to be the way you'll connect them to the logic board.

Also make sure you press down on the adhesive edges, that's the last defense you have from a water spill.

Then reassemble your MB/MBP.

If you just want a backlit for A1278 you could find it on eBay or even here on ifixit. Or even if your planning to replace both the keyboard and back lit.

Good luck with that.

***Step 3 Remove the clear plastic set it aside with the black film.

Step 4 There's going to be 6 row of 8 screws each that you'll have to remove. Be careful, if you strip one you'll have to drill the head off so you could remove keyboard. So when doing this Step take your time and use the correct screw driver phil#00.

Step 5 On the top left corner the power buttom ribbon there. You'll have to remove two screws.

Once you've done that, you could lift the keyboard out and replace it. Make sure that you put the clear plastic back. Instead of putting the black film back the backlit will replace that. Do make sure that you press down on that adhesive strip. That's your last defense encase of a water spill. Now reassemble the MB/MBP.

Hope that helps. Good luck with that.

iFixit sells a new keyboard, but it's not cheap. You might start by following the teardown instructions, and then pour some isopropyl alcohol on the keys and scrub them with a cloth (or maybe toothbrush?).

Let it dry for an hour before connecting it back to the rest of the machine. Good luck!
