ABSTRACT:
A method, system and computer program product for implementing a fault tolerant sleep mode of operation. The system state information may be stored in a volatile memory and in a non-volatile storage unit prior to entering the sleep mode of operation. If a memory corruption event, e.g., power outage, brownout, power surge, occurs during the sleep mode of operation, then, upon receiving an invocation to resume to a normal mode of operation, the system state information stored in the non-volatile storage unit may be reloaded into the volatile memory. By reloading the system state information stored in the non-volatile storage into the volatile memory, the computer system may resume to a normal mode of operation from a sleep mode of operation without any corruption or loss of data.
