摘要：Provided is a superior portable information processing apparatus, having adetachable liquid crystal display panel/input tablet, whereof the liquid crystal displaypanel/input tablet can be detached from the apparatus even when the main body is

powered on, i.e., is being operated. The portable information processing apparatuscomprises: support means for detachably supporting a liquid crystal display panel on amain body; detection means for detecting detachment/attachment of the liquid crystaldisplay panel; and first and second connectors for providing a connection for video signallines and a power line that connect the liquid crystal display panel and the main body.When the liquid crystal display panel is detached from the main body, the first and thesecond connectors can communicate with each other via a cable. When the detectionmeans detects that the liquid crystal display panel has been detached, the output ofvideo signals from the main body to the display panel is disabled, and then the powersupply to the liquid crystal display panel is halted (local suspend). As a result, thedisorderly open state of the signal output line and the power line to the display panelcan be avoided, and the deterioration of hardware can be prevented. In parallel to thelocal suspend operation, the main body of the apparatus saves data required for theresumption of a task, and halts the operation of the entire system (system suspend). As aresult of the system suspend function, a state of a processed application can be storedimmediately before the liquid crystal display panel was removed, and when the displaypanel is reattached, the halted application is smoothly resumed.
