Yes. The batteries are supposedly in parallel. Do you have a multimeter (on ohms, no batteries) that can be used to verify this? Could be a simple connection issue.

To get an icon/Windows Explorer reference USB Mass Storage, MTP (Media Transfer Protocol), PTP (Picture Transfer Protocol) or something custom (driver required) would've had to be implemented on the calculator. My guess none would fit (112KB total of code space). But HID would.
