A blade computer (110) designed to avoid disruption of client service even when it is extracted accidentally from the chassis. Each blade computer on a blade server system has a maintenance-free, large-capacity capacitor (112), which is charged with backplane power. When the blade computer is extracted from the backplane (101), that event is detected by an extraction detection circuit (114) on the blade computer itself. The extraction event triggers a power switching circuit (115) so that the electric power in the large-capacity capacitor will be supplied to the blade circuits. In addition, a CPU frequency control circuit (116) reduces the operating frequency of CPU. The CPU continues ongoing data processing tasks at a lower operating frequency than its maximum limit, consuming the charge in the large-capacity capacitor.
