I'm sure this has been answered at one time or another but I gave up looking at page 25 (the answer is probably on page 26!).
Anyway... the apostrophe key is not working and I am wondering if there is an easy way to fix it.
I'll be lost without it!:o

I would try Vacuuming and or shaking keyboard with keys facing level with you. Possibly a piece of debris. Good Luck.

Is it broken as in the key came off, or is the key completely normal and simply does nothing when you press it?

Sometimes laptop keyboards can be replaced rather easily and not nearly as inexpensively as you'd imagine. Sometimes.

Alternately, you can use your word processing program and teach it to replace all instances of some weird key combo with an apostrophe. For instance, when you type ]] it replaces it automatically with '

Good Deal, I like to try the cheapest, fastest, easiest test first.
