Question about Texas Instruments TI-81 Calculator

1 Answer

Took a battery out, put it back in and it wouldn't turn on.

I took a battery out of my TI-81 that I recently bought on eBay, and as soon as I put it back in, the calculator would not turn on. It had been working perfectly fine right before then. I don't know if anyone will be able to help, but I'd be extremely grateful if someone could. Thanks in advance. - Jeff

Try replacing both the AAA batteries and the back-up batteries. This should probably fix the problem.

This is about to be rather lengthy, so I apologize in advance. I traded for a 98 Firebird on April 19th. Already broke down. The problem doesn't lie within the engine or transmission however. What...

Sounds like the electrical part of the ignition switch, not the lock cylinder that needs replacing.
Possible also that cutting that wire to the security module immobilized it.

I recently took my Ti-84 plus apart. It will not turn on after trying to restart it and doing what manuel says. Any suggestions?

It might be an issue of the contrast. It may have been darkened when you removed the batteries and it is now light. try pressing second and up. That might do it.

Wont Display Anything , Black Screen !

The screens brightness might be set to the lowest number as a joke. Try to change that.

My TI-81 has completely stopped working. I have put in new AAA batteries along with a new CR1620 battery. Any suggestions?

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 do it, please append a comment to this post and we'll go on from there.

Phone won't start

Did you turn the phone off before removing the battery? I sure hope so. If not, you may have to junk it. My father has done that to several phones now. He pops the battery out to put the charged on in, but forgot to turn the phone off. I just recently bought him a phone that sets itself to power off when the battery cover is popped off.

I was able to fix the problem nut it requires several steps and only offers a temporary fix (untill the calculator is reset then it needs to be done again).
1. Press F5, then Dimond (symbol on buttion) then "Clear"
2. Press "alpha" then "S"
3. Press "0" dont mess with anything else here
4. Press "2nd" then "Quit"
Now you can turn it off but are missing the bottom text (rad,auto, etc...) to fix
6. Press "Mode" change radian to degree then "enter"
Now the text is displayed showing the mode.
7. Set the mode back to radian by reversing step 6.
Thats it I dont know how to get the bottom line back though...
