Question about Texas Instruments TI-83 Plus Calculator

1 Answer

I have owned my TI-83 for many years now. I only used it while in high school. When I was out of school I took the batteries out of my calculator so it wouldn't corrode. I just took it out of storage yesterday, put fresh batteries in and now it won't turn on or do anything. any ideas why?

    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.

    Does it?

My TI-83 PLUS wont turn on


Remove one battery from the calculator and then press and hold down the CLEAR key while re-installing the battery. While continuing to hold down the CLEAR key, press and hold down the ON key. If this doesn't work, then hold DEL and then ON. If unsuccessful, remove all the batteries, including the lithium watch battery, and leave the calculator like that for a while.

This is documented in the TI-83 Plus Guidebook, but unfortunately, not many people know about it.


If that doesn't work, send it to TI for repair. They probably won't even charge you!

Are you certain that the batteries are facing the correct direction and have enough juice?

Additionally, try holding the 2nd key and then the /down/ key, that darkens the screen, while holding up lightens it.

The TI 83 Plus was purchased in Sep 09 for my high school freshman. It hasn't been used much and now will not turn on. I've replaced the batteries twice. Any suggestions? Can it be repaired? Thanks


If the batteries are rechargable they may need to be removed and recharged. Lack of use does not mean that they hold the charge forever.

I don't know but try it.

My TI-83 Plus appears locked up no flashing


Try [2nd], [MODE] or [2nd] [ON] or [CLEAR] or take out a battery, this won't erase anything whatsoever as long as you have the factory back up battery in it, which unless you took it out, don't worry, you have it

Yes you can use it, here is the formula: Y= V(t+ (i/c))^(tc) V=amount put in, t=time, i=intrest rate, c= amount of times it is compounded.
(I know this because I have a TI-83 calculator)

My ti 83 wont power on


This just happened to my daughters TI-83. I took one of the AAA batteries out (any one will do since they are in series) and the backup battery out, and left it that way for about 10 minutes. When i put the one AAA back in and pressed the on button we were back in business.
