Ye olde TI-89 won't start anymore, I replayed the AAA batteries but still dead.
Is it truly dead or could it be the small backup battery that need a change too?

Make sure someone isn't pranking you and set the brightness to max

there should be a backup lithium battery, in addition to the 3 AAA. You may want to change that one.

Don't forget to do a complete "reset" also (small hole somewhere, don't remeber exactly)
