Abstract:
1. An apparatus for servicing an electrical/electronic device during power shut downs, comprising: a self contained service logic having a memory and control component for storing device information during normal device operation, said memory and control component storing data related to at least one failure of said device, the data being selectively retrieved after said device and said service logic are powered down; a switch for transitioning said service logic from a non-enabled state to an enabled state during a power shut down such that said service logic can enable one or more indicators driven by said data obtained from said data storage component of said memory and control component to indicate state of said device prior to shut down and failures potentially causing said shut down; said service logic also having a selectively-engageable auxiliary energy source that is charged during normal device operation and provides selective, temporary powering of said service logic when said service logic is transitioned by the switch from non-enabled state to enabled state during power shut down of said device; and at least one power isolation component in electrical communication with said memory and control component and said auxiliary energy source to prevent powering of said device by said auxiliary energy source during power shut down of said device, said auxiliary energy source being contained as part of a single self contained unit as said service logic, wherein when said selectively-engageable auxiliary energy source is engaged during a power shut down of said device power is selectively provided to said service logic during said power shut down of said device for enabling the one or more indicators driven by said data for diagnostic analysis of said device during shut down of said device.
