I'm thinking the calculator itself froze (stalled), or the circuit board is taking a long time to process the your command (telling the calculator to turn off). Maybe you should wait a few hours or so and see if it's still on. Did you perhaps take the batteries out while the calculator was still on? You may have damage the circuits inside of the calculator by taking the batteries out while the calculator itself was still on. Maybe if you put some new batteries in the battery compartment and press the "ON" button, it might function properly. This is a suggestion and I hope this works.

    No I didn't take out the batteries when it was still on. I tried using new batteries, nothing works. Nothing works in general. I can turn it on, like the black square that usual appears beeping when you turn it on. I tried pressing buttons and etc, nothing appears. I can't turn it off either.

    These are some more suggestions that might help. I saw two solutions in the guidebook. You can download calculator system software. Remove one battery from the calculator and then press and hold the "DEL" button while re-installing the battery you removed. Doing this will force the calculator to accept a download of system software. Connect your calculator to your PC with the TI-GRAPH LINK (I think it's the cable that came with your calculator). This will download current or new software code to your calculator. Just plugging that cable into the calculator without plugging in the other end of the cable will turn it on. Try pressing buttons on your calculator to see if they function properly.

    If that doesn't work, try resetting the memory by removing one battery, then pressing and holding the "CLEAR" button while re-installing the removed battery. While continuing to hold down the "CLEAR" button, press and hold down the "ON" button. When the home screen is presented, release the buttons. Press "2nd [MEM]" to display the RAM ARCHIVE ALL menu. Press the right arrow buttons twice and select "1:All Memory" to display the "RESET MEMORY" menu. Select "2:Reset". The message "MEM cleared" is displayed on the home screen.

    If that still doesn't solve the problem, I would consider three things... Either going to this support website- and contacting an associate, or unscrewing the calculator and taking out the buttons and observing the copper tracks (the object that is on the circut board under the buttons). Try fiddling with them by pressing them (batteries should be inserted in the battery compartment) to see if they work. Maybe the computer CPU inside of it wasn't receiving the information being punched in via the buttons. I've never looked inside the calculator for this model, but in one of my dictionaries I have a picture of a calculator and some of its internal parts. Your calculator may have a circular-shape lithium battery that is called the button battery. If your calculator has one, then that is probably what your problem is, so you will need to replace this battery. If all of that doesn't help, then you will have to go to plan B, which is to replace the calculator by purchasing another one. Hope all of this solves your problem and hopefully you won't have to buy another calculator!

Ti 83 plus charger

The TI 83 is a calculator, not a battery charger. If you want to use rechargeable batteries with it, you have to take the batteries out and charge them using a separate battery charger.

My ti-84 calculator wont react to anything and it says garbage collecting. i think the bar on the side should move and its not moving and its been like this for several weeks. i did download a whole pile...

I remember this happening once to my TI-83. I know it's a different calculator. But it happened frequently. Without completely reconfiguring the calculator, you can remove the batteries whenever you see the message and when you start it up again, it should be okay. It may continue to display this message once in a while. I used to just remove the batteries. I don't know if it will work on your TI-84 the way it worked on my TI-83, but I hope this helped!

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.

Why do I get an ERR: Invalid Dim 1:Quit Whenever I hit the graph key?

You're probably trying to graph a function that does not involve stat plot features. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.

If this doesn't do it, could you post the exact function you're trying to graph?

Whenever i try the graph on my TI-83 Plus the ERR:INVALID DIM 1:QUIT comes up and ive checked the STAT PLOT and i have Plot 1 set as ON.

You have to turn all statistical plots OFF before you draw function graphs. Press [2nd][Y=] to open the statistical plot configuration screen. Press [4:PlotsOFF] and then [ENTER]. When calculator answers DONE you are ready to draw function plots.

My TI-83 is all messed up

Sorry to hear that you are having problems with your TI-83. The TI-83 is a discontinued calculator, so I really don't think that it can be repaired/replaced.

See TI's website below for more information:,23871,-1,0,&jtfm0=&etfm1=&jfn=ZGEE602C53EA628B70E47DD2DD6878A5ABD632AD5834DE8ADC18D66ABBC9F888CBF7FB517A0B05B0984776B37370A28975B2
