Calculator turns on but keys don't work

Hi,

I have a TI-84 Plus. The calculator’s keys stopped working, as I was using it yesterday. I could still see the numbers I had typed, but could no longer type anything.

I took the batteries out and put them back in. I was able to turn on the device, but couldn’t do anything else. So power button is the only thing that works for me. I can’t even turn it back off.

I tried removing the internal battery. Didn’t work.

I took the entire calculator apart and cleaned the keys. Didn’t work.

I tried connecting the calculator to a computer via a usb mini cable but I wasn’t able to make the TI Connect CE software recognize the device. When I try to connect the TI when it is ON, it stops blinking with the cursor the moment the usb cable is plugged in. However, the TI CONNECT CE software doesn’t list it as a connected calculator.

Is there anything else I can do to help fix it?

Check if the keys are attached to the motherboard, then try again.
