@shah313 double check to see if there is a reset hole on the back of your calculator. Use a small object to depress the rest button in there. Let us know what you find.

On the back there will be a “P“ button in the middle. Press it and see if there is a difference.

I saw that the calculator was solar, so then I took my device and turned up the brightness and faced it to the front of the calculator. It started turning on
