Hello,
The batteries may be inserted incorrectly Should be +-+-.
The most common is that the screen is not dark enough: The calculator is on, but the user cannot see anything. The first things someone should verify are the two above.

If one wants to darken the screen one should proceed as follows.
Press the ON button (even if you cannot see the result)
1. Press [2nd] key and release it.
2. Press the [UPArrow] key , the one under [GRAPH], and release it.
3. Repeat Steps 1 and 2 in sequence until the screen darkens. One may have to repeat Step1, Step2, ...several times.

Dead Battery?


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.

After a few months on not using my calculator, I put in fresh aaa batteries and a fresh 3v button battery. Still will not go on :(


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.

I have a TI-83 graphing calculator and it keeps reporting 'Low Battery'. We replaced the 4 AAA batteries with a fresh set and got the same message. The calculator is less than 2 yrs old. Do I need to...


There can be two causes to this problem. One, the batteries that you put in may be expired. Some batteries have expiration dates on them (i.e. Duracell). If the year on it has expired or is coming near to expiring, you may have to put newer batteries in there that are longer lasting in years. Even if the expiration year is far-off, you still may need to put newer batteries in the bay. Two, your hypothesis of changing the lithium battery are correct. I read in the manual that you should change it every 3 or 4 years. The lithium battery is the back-up battery and it is like a memory card for you calculator. Whenever you put a new fresh set of batteries in the bay, the lithium battery saves your information while you are inserting the batteries in the bay. When you turn on the calculator again, it saves your functions that you've had in there. Hope this clears up your confusion! Reply back if you are still seeing the message.

Ti-83 won't turn on


Make sure you have the batteries in correctly. You may want to put fresh ones in for these procedures to work. The batteries alternate negative, positive, negative, positive. The first time I put my batteries in, I had one backwards and, it was hard to see that it was in backwards.

Make sure the IO ports at the top or, button of the calculator are clean. You don't want a dirty connection missing the procedure up later on.

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.
  1. 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. 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:

    ~Connect the TI Connectivity cable between the PC and the calculator.
    ~Click on Start >> Programs >> TI Tools >> TI Connect >> TI OSDownloader
    ~Follow the on-screen directions to reinstall the calculator's OS. When or, if the calculator install the fresh OS goto step 4.

  4. 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.

If this process did not work for. Try re-doing the process and, extend the time by 5 minutes before you put all the batteries back in the calculator.

I put new lithium triple aaa batteries in my TI-83. Nothing happened . days later it turned on worked for a little while then stopped. would it help to change the round lithium battery? Do you know what...


The button cell backup battery keeps the memory electrically refreshed when the calculator is turned OFF. The necessary power for regular use is supplied by the 4 AAA batteries (main power). That nothing happened when you put in a fresh set of (expensive) lithium batteries may be due to the screen being too dim to see anything.

If the calculator displays RAM CLEARED each time it is turned on, it may be due to a depleted backup battery. The battery model number is CR1616 or CR1620. On my TI84PLUS the backup battery is of type 303 (Sony) or SR44SW (Maxell).

My TI89 wont turn on. My back up batery is no good and not in is this a problem?


Hi,
The calculator must have a backup battery in. It will supply energy to the memory module when calculator is turned off. You may lose the content of the memory.
I do not want to sound dramatic, but you may lose the OS and you would have to reinstall it. Put fresh batteries and see if your calculator is still operable.

Hope it helps.
