Question about Texas Instruments TI-89 Calculator

2 Answers


I've tried numerous times to turn the calculator off, and it does so for a split second, but then it turns right back on. It seems the only way to turn it off is to take out the batteries? It used to work fine until a couple weeks ago. Any ideas?

    I know someone has a solution for this, it has something to do with changing settings, but I can't find it again....
    Does anybody know? I'm not doing an update, I don't have a cable.

Under your On button might be some dirt, that keeps triggering the On button, and thus, keeps it on.

I've had my ti-86 for a very long time & recently it just quit working. I changed the AAA batteries & the back up battery & it will not come back on. Please help???!!!!

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?

The unit worked fine when i last used it in the fall. I plugged it back in today and all the buttons lit up for about 1.5 seconds and then all the buttons went dark again. So I pushed the "on"...

I have had a problem like this in the past you can try taking the electric access panel usually on the side of the equipment. then look inside you will see a wiring harness inside and it literally takes nothing to bump it loose. This happens when people move these units they are pretty fragile and can be tempermental. Make sure the unit is unplugged while you adjust the wiring harness. If that deosnt work your display board is probably bad. Hope that helps
