Only some numerics (except the number 3), the return key and the trackpad work. All the rest give nothing. Absolutely nothing.

Also there there is strange behaviour when I place the pointer over the window menus. Sometimes it works "as normal" other times nothing. I fear that there might be also damage to the CPU... unless I got a virus (...not a really logical assumption, since I have ClamAV installed and do manual updates in addition to the automatic updates).

I am actually writing this on a Chromebook, since on the Macbook sometimes it opens my gmail message, other times, it simply provides me with other (non default) options such as delete / move / mark message, but doesn't open the actual email message.

FWIW, I did not use a dripping wet sponge. but a moistened "Magic Eraser". My gaffe was doing so while the machine was turned on <DUH> As such the machine is now seriously "crippled".

Also using a very hot hair dryer that close to the keys must have `fused` the microswitches under the keys.

I was able to find an company that deals with older Apple hardware, and was told that if a keyboard replacement could be found for this model, it would cost at least $200 to replace.... plus taxes, etc.

Bottom line: I should have left the keys dirty as they were. Nobody to blame but myself.

God only maybe knows what's in a Magic Eraser, but I'll bet it's not plain water and no doubt corrosive knowing what they can clean!!

It doesn't sound good, but you sure won't have a virus, but you could have some non-Apple software causing some confusion, but a cold boot using Safe Boot Mode would confirm that.

It sound like a trip to a good Apple tech may be in order for them to do some diagnostic tests.

I'd suggest that if it's acting goofy with a good known external keyboard, it's a more serious problem, and I don't know if the keyboard only can be located and installed in that model or if the whole top case is needed.

Then there's the lurking question if the logic board has been damaged. Not looking good.

Best bet for cleaning keyboards is a nearly dry alcohol wipe. What you are trying very hard to avoid is moisture under the keys. Alcohol evaporates very rapidly but if it has dissolved other contaminants, even alcohol could damage electronic circuitry.

I can recall having to help a lady who HAD to get access to some email for some trip details as she was leaving on a flight for her three month away job that afternoon, but her keyboard was almost completely dead after spilling some plain water on it the night before.

We managed to get access and send an email reply by using the mouse and the Keyboard Viewer to write the email.

BTW: After three months to dry out, her plain water damaged keyboard still didn't work. Quite strange, as when I finally took it completely apart, there was no apparent sign of any damage or anything stuck.

I've had to throw away an Apple keyboard after wiping it clean with a damp sponge,
A lot of the keys stopped working and never returned after weeks and weeks.
Finally just gave up and threw it away.

In my original post I mentioned that this is a Macbook. i.e. a laptop. Therefore, the keyboard is an integral part of the machine and not an external peripheral.
... If i were to 'throw away' the keyboard, that would mean throwing away the entire machine!

Doesn't matter, The keyboard still gets messed up with a sponge.
Throwing away your machine? Don't be silly, Just replace the keyboard.

Actually, the keyboard itself is not all that expensive: Amazon.com : Apple Macbook Pro 13" Unibody A1278 Replacement Keyboard US : Macbook Pro Keys : Computers & Accessories (assuming that this is the correct one!)

However, it doesn't sound particularly easy: Can the keyboard be replaced? - MacBook Pro 13" Unibody Early 2011 - iFixit

The entire upper case for this model appears to be $299 USD from iFixit.com.

However, you still don't know if the keyboard is the only issue - and that needs to be figured out before any replacements are attempted.

First, It is important to emphasise that this is not a Macbook Pro, but a regular (White) Macbook.
I realise that it is extremely important to make this distinction.

Secondly, the local repair shop here in Montréal gave me a quote of CAD $200 to replace the keyboard "if one can be found", to quote the serviceman. With present conversion rates, the canadian dollar is now lower than the US dollar.

Also, it has been about a decade since I used to build my own PC's. This is my second Mac portable, and I have never opened such a machine ... though I feel capable of doing so without any mistakes.

"About this Mac" says it is a 'late 2009 model', Model Identifier:
MacBook6,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2.26 GHz
Number of Processors: 1
Total Number of Cores: 2
L2 Cache: 3 MB
Memory: 2 GB
Bus Speed: 1.07 GHz
Boot ROM Version: MB61.00C8.B00
SMC Version (system): 1.51f53
The Macbook was purchased at the Apple Store, Montréal, on 18 January, 2010.

A couple of years ago, I found a script / utility that correctly and fully identifies any Apple computer. This is what it says about my machine (serial number not shown in this post, of course! ). A dash indicates no information provided.

Macbook 13" S/N: W***************** Group1: MacBook Group2: nothing Generation: - ModelCode: - CPU speed: 2.26 GHz Intel Core 2 Duo Family name: A1342 Screen size: 13 inch Colour: White Memory - number of slots: 2: 2 Gb 1067 Mhz DDR3 Factory: W8 (Shanghai China) Production year: 2009 Production week: 42 (October) Production number: 14947 (within this week)

In effect, it would be the second machine listed on this link that I found: https://support.apple.com/kb/HT1635


At the moment, I am using an external keyboard, and have disabled the login password. Since this is a 'generic' (soft roll-up) keyboard, I am unable to use any of the standard OS/X shortcuts. The scroll-pad works, but I am using two USB devices: the keyboard, and a mouse.

Thank you for such helpful comments, Paddy. Much appreciated!
