It works for an hour, and then it doesn't. I am now buying a replacement keyboard off ebay and going to install it in a bit.
It's a hardware grounding issue... as far as I can tell. And turning off features of battery management or usb devices using power or other related issues makes it better for a while, same with typing e a few times or z a few times will make the r or x key work temporarilly, but it's not permanent.
After installing the new keyboard (which took a couple of hours), it is working nicely and there have been zero issues after a few months. Note, that installing the keyboard did require clipping off some melted plastic bits holding the old keyboard up a tad. The first week was weird thinking the new keyboard was slightly sunken... but this is a non-issue compared to losing the r and x keys.
