Abstract
Abstract Upon detecting removal of a display section from a computer unit's main body, dismounting a battery (59), removal of a memory board from the computer unit's main body or the like, the CPU (71) saves system data no matter whether or not the resume mode is on and turns off the main power supply. Subsequently when the power switch is turned on the CPU checking if said system data is saved. The CPU restores said system data and restarts the data processing in case where the preservation of said system data is detected.
