Erratic keyboard, unregistered keypresses
I bought a used Macbook Pro (2007, 2.2Ghz), my problem is that the keyboard misses some letters that I type.
I've tried several firmware updates but I've come to believe it's hardware related. Some people seem to have the same issues with this model but I couldn't find any definitive answers.
The keys are all working, it's just that you have to insist (press it another time) sometimes to get it registere. It's highly annoying because I have to carefully proof read everything.
The Macbook was almost brand new.
Is it worth the try to replace the keyboard ?
