Troubleshooting Reset Issues
Sometimes, a TI-84 calculator may not reset properly, or it may not respond at all after resetting. In these cases, there are a few troubleshooting steps that can be taken to try and resolve the issue.
First, if the display is visible but appears locked up, the user can try pressing the RESET button on the back of the calculator with a paper clip for 2 seconds and then release it source. This will erase the contents of RAM, such as lists and programs, but it may help the calculator respond again.
If the calculator still does not respond, the user can try performing a RAM reset or a Full Memory Clear. To perform a RAM reset, the user can press the [2nd] + [+] (MEM) keys, then select [7], [2], and finally [2] source. This will take the calculator back to when it came out of the package, and it may help clear up any issues.
If the calculator still does not respond after a RAM reset, the user can try performing a Full Memory Clear. To do this, the user can press [2nd] + [+] (MEM) keys, then select [1 Memory], and finally [2] source. This will erase all data, programs, and apps from the device, and it will restore the calculator to its original factory settings.
If none of these troubleshooting steps work, the user may need to contact TI customer support for further assistance.
Maintaining Calculator Health After Clearing
Once a TI-84 calculator has been cleared, it is important to take steps to maintain its health and performance. Here are some tips to help keep your calculator in good condition:
