This issue is more common with newer TI-84 Plus CE calculators. Sometimes they won't charge dead batteries. You can try charging the battery in a friend's calculator or get a replacement battery.

If your calculator is within warranty, you can contact TI Cares and they may send you a new battery for free.

Try the following as they seem to be the most likely cause:

  1. Remove the battery and let it sit for ~10 minutes, reinsert the battery and see if it resolves the issue.
  2. Replace the battery, it seems the most common fix is ordering a new battery, here is the link to buy a replacement battery from Texas Instruments (far cheaper than Amazon) https://epsstore.ti.com/OA_HTML/ibeCCtpI...
