BATTERIES, Tim.

Batteries. Batteries. Batteries.

That is the description of what happens to TI Graphing Calculators when the battery power diminishes. The calculator will always reduce its display contrast in order to maximize time till expiration. There should have been prompts to warn you of its impending doom.

So, if it was very dim one day, and failed to display another day; then it most likely lost its battery power.

REPLACE THE BATTERIES.


By the way, your calculator has lost all of its memory when it completely diminishes. So, if you want to avoid losing all of your content then I would suggest your replace the batteries before battery expiration.

My TI 83 Plus does not turn on. I have replaced the batteries and the backup battery. I have tried all the troubleshooting solutions given but still it does not turn on. What can I do now?


The screen may be too dim to read. Sometimes when the batteries are low, the screen automatically dims itself. The problem is, it doesn't undo that when the batteries are replaced. Try pressing 2ND->Up arrow key repeatedly while the calculator is turned on and the screen should start to darken so that you can read it.

TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

If this doesn't fix it, please reply to this post and we'll go on from there.

Do I lose all info if I change out the batteries?


Not if the backup battery's good---that's what it's there for. You may not be able to read the screen afterward, TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. If this happens, turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.
