A couple of months back, I had “cleaned” my macbook with Colin and ended up destroying my keyboard 🙁
Also, my extended warranty had expired just a few days back; so when I went to the Apple support centre – they gave me an estimate of ~15,000 INR. Considering that the macbook is >3 years old, and that I have 2 other laptops at home, the cost was not justified.
I searched the net for options and finally came up with the following:
Keyboard from: http://www.aliexpress.com/item/New-US-Keyboard-For-apple-MacBook-Unibody-A1342-MC516LL-A-MC207-2010-Free-Shipping/617432777.html
And Instructions from:
http://www.ifixit.com/Guide/MacBook+Unibody+Model+A1342+Upper+Case+Replacement/2185/1
As these instructions are for replacement of the entire upper case – there were a few more steps and brute force required to pull out the old keyboard and replace the new one – in the process – I broke a few plastic parts – but the new one works like a charm 😀
