How
do I correct the Error
Waiting...Please Install Calculator SoftwareNow
message on my TI-83 Plus family or TI-84 Plus family calculator? If an operating system (OS) update fails or is interrupted, the calculator will be in an inoperable state with the message
Waiting...Please install calculator software now.The
most common cause of a transfer being interrupted is updating
the operating system on a calculator with low batteries. Users will need
touse the TI Connectivity cable and the TI Connect
to send
the operating system to the calculator. Make sure to have the
latest version of
TI Connect installed on the computer.
In order to install the software please follow these steps:
1. Connect the TI Connectivity cable between the computer and the calculator.
2. Click on Start >> Programs >> TI Tools >> TI Connect >> TI OSDownloader
3. Follow the on-screen directions to reinstall the calculator's OS.
If the
message "Error! Press any key to turn unit off. Then turn unit back on."
appears on the graphing calculator, quickly, remove one battery from the
calculator and reinstall it while the transfer is taking place.
Hope it helps.
same problem as ashleycullen's. My calculator was working fine yesterday but I tried turning it on today and it wouldn't. I tried replacing the batteries and that didn't work. I tried to reset it but that didn't work either.
I used my claculator on Sunday and it won't work today on Thursday. I am frustrated.
I also cannot switched on my GC even though i changed all 4 batteries. sometimes it can be switched on, but after some time, it just died off by itself....
The screen stopped working on my calculator. I have relaced the batteries, pressed the reset button, and tried to modify the contrast. My computer recognizes a device being attached to the computer when pressing the on and off key on calculator.
