How do I fix my calculator. It's turned on all the time. Even when I remove the battery and put it back. I can't type anything but press "on" button.

Take out the batteries. Also take out the backup battery. It is a button battery beneath the screw in the battery compartment. Check the button battery volts with a multi-meter. After 5 minutes put the button battery back in and then the fresh batteries. It might work now. Alternatively take out a battery, then hold the clear button and put the battery back in. Then try to turn on. If it still does not work take out a battery press the del button and put the battery back in.

I've had this issue before with my TI-83 Plus. I'm not sure exactly the solution I used, but these steps progress through the mildest to most extreme methods of fixing the calculator.

Solution 1: Take the batteries out.

Odds are you've tried this already, but it bears mentioning.

With the calculator on, remove the triple A batteries housed in the back. After a few seconds, replace them and turn the calculator on.

Solution 2: Clear the RAM.

Remove one of the AAA batteries. Press and hold the [CLEAR] key. While holding [CLEAR], reinsert the AAA battery and then turn the calculator on. The calculator should display the message "RAM Cleared". Release the [CLEAR] key and then press it one more time to remove the message.

Solution 3: Reinstall the operating system

Remove one of the AAA batteries. Press and hold the [DEL] key. While holding [DEL], reinsert the AAA battery and then turn the calculator on. The calculator should display "Waiting...Please install calculator software now"

Here is the website to reinstall your OS. First you'll need the TI-Connect software.

Solution 4: Remove all sources of power. This is a risky move, but if your calculator will absolutely not work after you try even reinstalling the operating system, it might be your last hope.

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.

Hi persaud sabr,

Make sure the batteries are in correctly? The batteries alternate negative/positive, positive/ negative and so on. The first time I put the batteries in, I didn't have them in correctly. I know if it happen to me anybody could make the same mistake. and of course the calculator will never come on if the batteries aren't in correctly.

The process below should reset your calculator.

Please be prepared to re-install the calculator's OS if you run through this process.

Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds. Now, Pressing the [2nd] key followed by pressing and releasing the up arrow; repeat as necessary. Is the screen showing any activity? If not continue the process.

   reinsert the AAA battery and then turn the calculator on. The calculator should display the
   message "RAM Cleared". Release the [CLEAR] key and then press it one more time to remove the message. If calculator did not display the message try pressing and releasing the [2nd] key followed by pressing and releasing the up arrow for one second. goto step 2.
   
2. Remove one of the AAA batteries. Press and hold the [DEL] key. While holding [DEL], reinsert the AAA battery and then turn the calculator on. The calculator should display
   "Waiting...Please install calculator software now". Follow the instructions for the
   TI-83 family or TI-84 Plus family to reinstall the calculator operating system. If the calculator did not turn on connect the calculator to the computer and open Ti Connect. Next, open Device Explorer. Is the calculator asking to be installed? goto step 3.
   
3. Steps to re-installing the operating system:

Hello,
When you change the batteries the display reverts to default setting. My optimistic guess is that the screen display is so light that you cannot see anything on it. This can be arranged.

2. Even if you see nothing, press the [2nd] key and release it.

Hope it helps.
Thank you for using FixYa.

look on the back cover and find the reset button, use a pen and press it and see if it clear the problem also check the batteries they might be dead check the back cover and see what type you need take it to the watch repair dept and buy some batteries and have them remove the back cover of the calculator and replace them. put the cover back on . your calculator will work as good as new again.

There is an easier way. No deleting anything involved. When you turn on your calculator and it says "Garbage Collecting" take out all 4 AAA batteries. Then, either put those same 4 back in, or replace them with 4 new ones. Then, hold down the -CLEAR- button, and then at the same time, press on. If your batteries are almost dead, nothing will pop up but it will look like the screen is kind of flashing. New batteries will fix that problem in a jiffy, and then brand new calculator :) Worked for me, hope this helps!

I had something similar, it kept saying "battery low" after putting in new batteries. Try the Clear method; Take out one battery, hold the Clear button, while holding it insert the battery again and press on, and release. Now press clear again, turn it off and turn it back on again. If that doesn't help... well it must be something else... sorry :S
