You can also reboot (AKA coldstart) by poking a paperclip into the RESET hole under the battery cover. The word RESET is embossed in tiny letters next to the hole. The same RESET hole is in the 15C LE and recent 12C's. For easy access to the RESET hole, I suggest removing the screw from the battery cover permanently.

Notice that attempting to perform a standard reset by turning on the calculator while holding down the subtraction key only works in HP-15C mode. In HP-16C mode, it hangs, requiring a paperclip reset to recover.
