Yoda,

Luckily, I was able to snap back on the "o" key the other day. Got frustrated trying to type without the key on & decided to just try to snap it back in there & so far, so good. The first try only lasted a couple of hours, but I think I got it this time as it's lasted with all my typing this afternoon.....when the key fell off, there was so much lint under the key. I have the air to spray clean the keyboard, but it doesn't get that much durt out that was stuck....I used some pointed tweezers that I use for my beading & that worked well to clean out under all the keys.

If the bracked on the back of your "a" key is still on, there is usually a little space that hooks onto a hook like thing on the keyboard.....that was why I thought there might be a tool or something to put the keys back on with...but ended up just snapping it in place.

Good luck with that....I hate it when the keys come off. One of my puppies jumped on my other laptop & broke off one of the keys including the bracket, so there was no replacing it.

Ah, the joys of computers...always something breaking or going wrong.
