Question about Texas Instruments TI-85 Calculator
I haven't used my ti-85 since college (almost 10 years now...wow I'm getting old). I couldn't get it to turn on, so i replaced all the AAAs and the back-up battery. I'm still getting nothing when I try to turn it on. My wife has a TI-83 that we use around the house frequently, so I'm not as totally clueless as you might expect. I've tried turning it on and darkening the screen using the 2nd function button and the up arrow key...nothing. One of the contact plates for the positive end of one of the AAAs is missing. There is still a metal spring/lead underneath where the plate should be. The battery contacts this spring/lead. Is that my problem? If so, do you have a suggestion for getting it fixed without having to send the calculator off to TI?
I'm wait for the solution please!

That is perfectly normal, almost all of TIs graphics calculators have it.

This worked for me, you just take out the batteries and let it power down for a few mintues, and bam when you turn it on again, its fine.

Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute
period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary.
Just keep trying. Sometimes they can be a pain.
