Keyboard backlight is working properly, but keyboard itself - doesn't
Some months ago I had bought a MacBook Pro 15" 2011.
The previous owner said that keyboard and backlight don't work + touchpad was dead.
I decided to put a brand new battery inside and install an OS X on SSD.
During the installation, kind of miracle happened - the backlight started to work.
Now, I have a fully functional MacBook with new battery and fresh OS X.
I had an idea, that to repair the keyboard and trackpad I need to do the reset of SMC and PRAM. Unfortunately after these manipulations nothing had changed.
Then I reinstalled the OS X, thinking that some kexts didn't install properly at first time due to bad PRAM, SMC or whatever.
But I still have no response from keyboard and trackpad.
The Apple Hardware Test didn't find any problems with my Mac, the only problem was the problem with battery, but I think that all batteries which is not OEM have problems...
So, guys, maybe you have any suggestions before buying the new keyboard and trackpad?
Is this a good question?
