Suspend/resume capability for a protected mode microprocessor and hard disk, and idle mode implementation

摘要: A portable computer system includes a protected mode microprocessor (311) capable of operating in restricted and unrestricted modes, an arrangement which response to predetermined condition saves information from the processor then forcibly switches its operation. When running multitasking where application program is being executed mode, certain types processing can be carried out after entered due condition, interrupted resumed with back effect. An idle feature automatically decrease increase speed clock (387) when user activity stops later starts again, conserve power.
