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.

If this doesn't do it, please reply to this post and we can go on to the next step.

My TI-84 calculator isn't working. When I press the "ON" button, sometimes it would respond, but most of the time it doesn't. The screen just remains blank. I've changed my batteries...


try taking out the triple A batteries and leaving the calculator to sit with them out for a minute or so, replace them and check if it's fixed. If that doesn't work you can do the same, but take out the small button back up battery as well. If you're still not having luck you should call ti cares (800-842-2737) they're usually helpful.

Replaced batteries now i have black screen


Check the contrast levels (2nd+Down). If that doesn't work take out the 4 aaa's and set the calculator down and wait for a minute or so (for the power to drain from the capacitors) replace them and check if it worked. If that doesn't work, take out all batteries, including the small watch battery and leave it sit for a minute or so, replace them and check. Finally you can try calling Ti-Cares (1-800-842-2737) they're very helpful.

Change all batteries, and have update with the new OS but the calculator is still unstable. Cant turn on the calculator sometimes


You can try to reset it by leaving it sit with the aaa batteries out. If it's still acting strangely you can fully reset it by taking out all of the batteries (including the back up watch battery) and letting it sit for a bit. If that doesn't work either call Ti-Cares 800-842-2737, they're very helpful.

My TI83 calculator hasn't been used in a few


Is it that your "Enter" key won't depress or it doesn't respond?

My ti 84 plus does not want to turn on, i thought it was battery problem so, i bought new batteries but i stil have a blank screen.


Could it be that your screen has been dimmed in error. Turn the calculator on & press the 2nd key and then the up arrow. This darkens the screen.

If this doesn't work, try taking out the backup battery. It is located in the battery compartment, behind a little door that you must take off with a phillips screwdriver. Leave it out for about 10 hours. If this doesn't work, try replacing the backup battery.

Hope this helps.

I turned on my calculator, and whenever i press clear, i get multiple "carrot" signs, when it even works. The number's will work sometimes, but i can't get the calculator to turn off....


You may want to try & reset your calculator. Take out the batteries including the backup battery behind a little door in the battery compartment. You'll need a small phillips screwdriver to take out the battery.

Leave the batteries out for at least 10 hours and then reinstall them and try your calculator again. If this doesn't work, try replacing all batteries including the backup battery.

Hope this helps.

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.

Ok, so i replaced the batteries in the calculator.. And now it wont even turn on. Brand new batteries and everything, Any suggestions?


Hey this sounds like the classic contrast problem.
But first make sure that the batteries are good and that they are installed with the proper terminals alligned correctly
Second, and this is the classic problem, turn on the calculator and then press second and up. The screen should begin to darken and you should begin to see the cursor.
If you go to far or in the even that the screen is dark, lower the contrans by pressing second, 2nd, and then holding down.

Hope this helps
Happy Calculating
