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.

Hello,
How do you contact TI Cares? Do you just email them? Also how do you know if your calculator is fully charged if you can not access the menu?
Thanks
@iceee84521 you can look them up. Their site tells you how to contact them: https://education.ti.com/en/customer-sup...
You would need a volt meter to check the battery's state of charge. TI use to have a charging indicator but removed it to cut costs a few years ago.
