Calculator will not come on

I can not get my calculator to come on. I have installed new batteries, both the four AAA and the backup #1616 battery and it still will not come on. What can I do?

    I did the first step but after the home screen is displayed Iam not going nowhere with the others steps. The cursor moves but not really working on the menu...

    I've replaced the batteries multiple times. Sometimes it won't come on. When it does come on, there's lines and random letters and figures, no matter what I do. How do I make my calculator work normally again?

I have the same problem with the calc not responding to removing one batt and reinstalling while holding clear, etc. My fix is to hook up wires to the battery leads and plug the wire into a 120 volt outlet. Watch it light up, but do NOT breath the smoke as it is extremely toxic. ;-) lkw



Remove one of the AAA batteries. Press and hold CLEAR while reinstalling the AAA battery. Continue holding CLEAR button and press ON. Release buttons and press CLEAR again. Calculator should be normal mode now. ;0)



I read in the TI-83 Plus, if you happen to change both AAA's and the lithium battery all out at once you have 2 options. The 1st involved downloading software using Ti- Graph Link and a PC. The 2nd was similar to your suggestion involving resetting all memory. 1. Remove one battery. 2. Press and hold CLEAR while returning battery. Press ON (having not released CLEAR).When the home screen is displayed release the keys. 3.Press 2nd [MEM] to display the MEMORY menu. 4.Select 7:Reset to display the RAM ARCHIVE ALL menu. 5.Press > > to display the ALL menu. 6.Select 1:ALL MEMORY to display the RESET MEMORY menu. 7.Finally...select2:RESET. The message MEM CLEARED is displayed on the home screen.

    I held down the clear button and replaced the battery. That seems to fix it. Thanks!

Open the battery compartment. Above the four AAA batteries you should see a small screw. Unscrew that to uncover the backup battery.

I get black "lines" going across the screen when i hit the graph button. It will graph also,but you can barely see the graph. Help pleae.

For the TI-83 Plus Family, TI-84 Plus Family:

Caution: The resets described in these troubleshooting steps will cause a loss of applications, programs and data. If at all possible please create a backup using TI Connect first.

1. Try a new set of AAA batteries.
2. Adjust the contrast by pressing and releasing the 2nd key followed by pressing and releasing the up arrow; repeat as necessary. To adjust or lighten the display, use the down arrow.
3. 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.
4. 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.

Is there areset button my keys are frozen

Unfortunately, you can only access RESET from within the menus of the calculator. You will have to remove all of the batteries and let the system naturally reset. The TI-84 Plus uses five batteries: four AAA alkaline batteries and one SR44SW or 303 silver oxide backup battery. The silver oxide battery provides auxiliary power to retain memory while you replace the AAA batteries. Re-install the batteries and reprogram your functions.

What kind of battery does the TI-83 take

4 AAA batteries and one CR1616 or CR1620 button batter for backup

I have a TI84 plus texas instruments i have removed both the batteries in order to reset the unit but it still has not resetted the unit. All I am getting all zeros on the screen

First try removing all four AAA batteries and the small lithium backup battery (above the four AAA batteries). Leave all batteries out for five minutes, then replace them and try to start the calculator. If this doesn't work...

Replace all but 1 AAA battery. Press and hold the "CLEAR" button on the calculator. While holding the "CLEAR" button down, replace the missing AAA battery. While still holding the "CLEAR" button, turn the calculator on. The display should read "RAM Cleared". Release the "CLEAR" button and press again to remove the message.

If that doesn't work, remove 1 AAA battery again. Repeat the preceding instructions with the "DEL" key: With the battery removed, press and hold the "DEL" key. With the "DEL" key held down, replace the battery and turn the calculator on. The screen should say "Waiting... Please install calculator software now." Release the "DEL" key. Download this program onto your computer (from Texas Instruments). Connect the calculator to the computer using the USB cable provided with purchase. Run the TI OSDownloader program and follow the on-screen instructions to re-install the calculator's operating system.

In order for the calculator to work do you need the AAA batteries and the back up battery?

The backup battery is to preserve the contents of memory while you replace the main batteries. If you don't care whether the memory remains while you do this, then you don't need the backup battery. The calculator won't work without the AAA batteries, but will work without the backup battery.

I have a TI-83 Plus. It just died. I have replaced the 4 AAA batteries and the lithium 1616 backup battery. I have checked to verify that the screen hasn't just dimmed. I get nothing. Any ideas?

Remove all four AAA batteries. Press and hold the ON key for ten seconds. Replace the batteries. Turn the calculator on (you may have to adjust the screen contrast again).

If this doesn't do it, please add a comment to this post and we'll go on from there.

Do i need both the back up lithium battery and the 4 AAA batteries for my TI-83 calculator to work? Or can it work only with the 4 AAA?

The calculator can work with just the AAA batteries. But, without the backup battery, you'll lose all the contents of memory when the AAAs die. The backup battery is intended to keep the contents refreshed while you replace the AAAs.

Turn-on woes My TI83 will not turn on. Batteries new and installed correctly. What gives? Khumalo

Take out the AAA batteries and hold the on/off key for thirty seconds. Replace the batteries and it should come on. If it doesn't remove the backup battery and the AAA batteries and hold the on/off key for another 30 seconds. Replace all batteries and turn it on again.
