I would check the voltage of the supply with a multimeter while the calculator is turned on.
And can the calculator do any other function while still connected to the computer?
The computer delivers five volts from the usb port.
If the calculator goes bad or stops functioning correctly after a short term, I would be looking to replace the battery. Some of us have had batteries that initially read
the correct value, but the voltage drops after putting a load on the battery.
Thanks.

Thank you for your information, but the 4-volt external regulated power supply is directly connected to the battery pin. Unless the power exceeds 30 watts, it will provide a constant 4-volt voltage
