Computer diagnostic having an LED to provide direct visual feedback as to the status of the standby power supply when power button is actuated |
摘要 |
An electronic apparatus is described with a power provisioning system for powering the apparatus from an external power source, a power button connected to the power management control circuit for enabling a user to initiate transitions of the power provisioning system between at the first and second states, and an LED for providing a visual feedback to the user of the powered state of the computer; in which the LED is wired in series with a transistor to the standby supply output, the conducting state of the transistor being controlled directly by the power button so that the LED provides a direct visual feedback as to the state of the standby power supply output when the power button is actuated.
