Lifted button

Mi Problema

I though the button on this not-so-old mac book had given out, since it wasn't clicking well. Seemed "dead." But the comments of others here suggested it might be a bulging battery.

Mi Solución

Sure enough, it was the battery. Barely noticeable. New battery, happy track pad button.

Mi Consejo

Don't jump to conclusions about what's gone wrong. Look around first!
