Calculator seems to be unresponsive
My calculator turns on and shows the ram cleared after turning on and then when you try to input anything the cursor just gets stuck and hangs. Nothing happens after that. it is unresponsive and does not responds to any input given and just stays blank. i have removed all the five batteries and replaced but still the same. when i try to connect it with my laptop it not being detected by the software.
