I have a strange issue with this macbook. The built in keyboard and trackpad just all of a sudden died (no light in caps lock for example). Nothing works. But if I plug in a usb mouse and external keyboard they both work fine. Its not a hardware issue because If I use a linux live usb key and boot into it at start up the keyboard and trackpad work fine.
I was wondering if anyone else has had a similar issue. I've seen issues like this, but those are all from a few years ago at least.
