Question about Texas Instruments TI-84 Plus Calculator
Changed batteries and still get last formula typed in, screen won't clear
I tried furiously blowing in to the back of mine with all 4 AAA batteries and the back up battery removed
then i left the batteries out for 2 days
it works again with really minimum use... you have to repeat the blowing and leaving out nonsense every week
sometimes you regain use by rubbing the AAA batteries back and forth while they're in place
better get a new one if you can afford it
