Question about Texas Instruments TI-84 Plus Calculator
Hope you already checked batteries. If not do it. Was the closet Hot? It takes a small allen wrench to remove the back of the calcul but it worked well for me. I cleaned all my buttons off. and then cleaned the front face that the buttons go through. Warning - move very very slowly or all the buttons fall off and you may not be able to remember the order they should be in. ALso, your ram will be erased so back it up first on your computer.
