Il Mio Problema
5 keys stopped working.
La Mia Riparazione
Repair went extremely well using iFixit guide. The only small glitch was that the new top case didn't come with the trackpad set screw so initially, the track pad wouldn't click. I had to take the screw out off the old top case.
Il Mio Consiglio
Broken laptop is as good as new for just under $ . . .
