Abstract
A system and method for establishing and maintaining date information associated with an electronic device. The system is typically configured to prompt a user to enter or otherwise establish a valid date at some point after power is applied to the system. After establishing a valid date, the real time clock is configured to maintain real-time date/time information. Upon determining that a valid date has been set, the system may subsequently obtain date/time information from the real time clock and store the obtained date and time in the non-volatile memory as the in-service date. The system may be enabled to determine if, subsequent to establishing an in-service date, the user altered the date/time information in a manner that indicated an intent to extend the warranty period beyond the manufacturer specified warranty period. In an embodiment suitable for use in conjunction with a server blade, the system includes a main processor and a service processor that handles low-level functions associated with the server blade. The in-service date information may be stored in a non-volatile memory of the service processor. This non-volatile memory may be implemented as an EEPROM that incl…
