Question about Texas Instruments TI-30X-IISTK Scientific Calculator

1 Answer

TI-30x IIS stopped working

This cheap but good pocket calculator stopped working suddenly. I suspected the battery was the problem and took the old one out. Never tested the battery and now don't remember which way it was in the calculator. The battery is a size of a dime and there is red wires on one electode and black wires to its face with many spots that will touch the battery. Now I tried both ways and it still doesn't come on and now think I might have shorted it out. It says to reset you need to press "on" & "clear". Now I think that I need to press both at the same time which I still have not tried. I have rather press "on" first and then "clear". Have I broke it or should go back to battery store see if they can get it to work? The battery that goes with it is CR2025 3V.

After about 4 times putting the battery in it, it finally started working. I was just about ready to return back to the battery store.

Battery replacement J-10A

Good Morning Fhaas153

Looking at a J-10 picture on eBay , the picture of the rear says '1.5V battery x 2. Looking at this other shot It looks like there is a fairly clear Slide-to-Open Battery door at the top of the rear panel. Given the battery rating at 1.5 Volts and the door size, I'd suspect it'll take either AA or AAA batteries. You should be able to slide the door and look, and most battery compartments will have an indication of the specific cell.

To be sure I'm covering both the what and the how, slide the door open. Remove old batteries if still there. Clean up contacts with a bit of fine steel wool if they are corroded or covered with old battery fuzz. Put new batteries in - negative end towards the coil springs generally. Replace sliding hatch.

Hoping this covers what you're looking for!

My calculator keeps going off. The batteries are less than an year old. I would reset it. It works briefly and suddenly stops.

In my opinion your calculator may suffer from the depleted battery syndrome. Certainly the first thing one should do is to replace the batteries with a fresh set. If the behavior persits then there is a problem.
There is no set value as to how long a battery should last. It all depends on the frequency and durarion of use.

I would like a battery operated hand held calculator to use in Oregon state testing at the elementary level. Our students take the test on computers so we turn out the lights so the screens are bright and...

I am not sure that you can find good battery operated calculators at this price range. However is as you say the testing is at the elementary level, maybe some cheap calculators found at dollar stores will do the job.
Cheap calculators are often used as promotional items.

Since testing is done on computers what not let the students/applicants use the calculator application that is found the computers. I do not know about Apple products but PC computers have a calculator usually found under Accessories (in Windows XP). If you find a way to dock the calculator application on the screen or show the students how to raise tha calculator window quickly, you will not need to buy additional calculators.

SPV C500 Charging problem

If you mean the amber 'charging' light does not light when charging, note your PC must have a working Microsoft ActiveSync installed on an XP, Mobile Device Manager on a Vista PC, before the phone will charge from a PC USB port.

If it will also not come on when the AC charger is connected, then I would suspect a bad light or what ever supplies the light.

How do you know it is not chargeing if the phone comes on. Are you saying the phone will only come on when plugged in a PC or AC Charger? If so, I would suspect the battery. Unplug it and clean both the battery terminals on the battery those on the phone the battery mates with. You can use a clean pencil erasure.

Batteries are cheap on ebay.

TI- 83 Plus Silver Edition problem

Many 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 at all. 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.

I don't even know!

What i think is that your calculator has water damage. It is not dead. There still is hope. The slow response is due may be due to a short in your I/O port. Blow really hard in there that might stop the slow response. Other than that let it sit without the batteries to dry. Then put the batteries back in and if that doesn't work its probably what spongeboob said and your going to need to ditch it.

Error message

I fixed this exact problem on my TI-5006 II calculator by simply replacing a "dead" battery. Three of the four battery's were good (after cleaning their terminals) but the fourth was completely bad (i.e. read "Replace" on my Battery Tester). Other problems probably can cause this exact same error message but this cure was simple and cheap. The problem first appeared after the calculator was dropped. A sudden shock (dropping it) can cause even a good battery to fail.
