@thelastmill Thanks for the quick response! Yes, it is definitely a TI-84 Plus CE. I just tried the 2nd+Del+Reset combo you mentioned, but still no response. Something interesting— The calculator is not showing up in Windows’ device manager nor in driver installation menus (“Unknown USB Device”) but unplugging/re-plugging or hitting the reset button triggers the “new device” sound in Windows 10. When I first plugged in the Calc, the Light by the charging port lit up red. After 2-ish hours charging, it is now green— I am aware that the battery/charging circuit is seperate from the calculator itself, which may be the source of this issue. The calculator was working last week during a math test, during which the screen turned black. The battery was charged to ~80% at the time, and the device was sitting on a desk— no physical damage occurred, and the calculator is only around a year old.
