My calculator has frozen up. You cannot clear it or input anything


The first diagnostics you should perform are:
  1. Make sure batteries are good and inserted correctly, respecting the polarity diagram: Yes, I myself made this mistake and it must be ruled out before doing anything else.
  2. After a change of batteries, the screen contrast can change: It may become too dark or too light. If it is too dark, you would not think about a malfunction because you see something on the scree. BUT it the screen is too light, it is easy to conclude that there is a malfunction because you do not see what the calculator is doing after you press a key.
  3. So, the second measure is to adjust the contrast. Press [2nd] key and Release it. Then Press and HOLD the UpArrow until screen is dark enough.
  4. A third easy measure is to use the TIConnect software (available on education.ti.com) to retrieve the device Info, and if calculator is recognized to reinstall or update the OS. You need a TI USB SilverLink cable.
Here are some more procedures to perform in the order they are presented. Please read the post till the end.

A
  1. Remove one of the AAA batteries.
  2. Press and hold the [CLEAR] key.
  3. While holding [CLEAR], reinsert the AAA battery and then
  4. turn the calculator on.
  5. the calculator should display the message "RAM Cleared".
  6. Release the [CLEAR] key and then press it one more time to remove the message "RAM Cleared".
B.
  1. Remove batteries including the backup battery for 5minutes.
  2. After the 5 minute period, reinsert all of the batteries and
  3. turn the calculator on.
  4. Adjust the contrast if necessary. (see above)

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.

Changed battery, still not turning on. what do i do?


The most frequent cause for this ''not turning on'' is a screen that is too light to see anything displayed. Try increasing the screen darkness.
Press 2nd key and release it
Press and hold the Up Arrow until it is dark enough.

If the does not work
  1. Press 2nd key and relese it
  2. Press UpArrow and release it
  3. Repeat the two steps until screen is dark enough.

First test if it works on an external monitor. If it does you will need to clear the CMOS. To clear it:
remove the battery, unplug the cord, and hold the ON button down for 30-60 seconds. Then turn it on. Thats how you clear it on most laptops.
If it does not work on the external monitor, you probally have a bad video card and need to replace the old one
