Above-mentioned park mode is meant computer system operation in the state that is similar to shutdown, as advanced configuration power interface standard (Advanced Configuration ﹠amp; Power Interface) defined internal memory sleep mode pattern (Suspend To Ram) or disc dormancy pattern (Suspend To Disk).Advanced configuration power interface standard is to be dominated with Toshiba (Toshiba) by Microsoft (Microsoft), Intel (Intel), and having formulated jointly with " operating system " is the power management routines of standard, operating system is transferred in power management work be responsible for.Advanced configuration power interface standard is divided into four kinds of states such as operating system, hardware environment, province's electro ultrafiltration to do planning, is respectively system (Global) state, device (Device) state, dormancy (Sleeping) state and processor (CPU) state.Wherein, dormant state can be subdivided into following five states:
1. state S1: standby, system can resume operation very soon, and also loses without any data between system, and the output of screen signal is closed, and hard disk shuts down, but total interface still keeps power supply.
2. state S2: similar S1 state, but the data between central processing unit and high-speed cache (Cache) lose, reply the back system and need safeguard data between CPU and Cache again.
3. state S3: the internal memory sleep mode pattern, except internal storage data, other data are all lost, and internal storage data needs by hardware maintenance (internal memory need be powered).When entering this pattern, all data preservations that are stored in the internal memory are motionless, enter " false shutdown " then.Keep data except internal memory needs power supply this moment, and other unit, interface are all stopped power supply.Again after the start, computing machine promptly can be got back to the into preceding picture of S3 at once just behind the data integrity validation of internal memory.
4. state S4: the disc dormancy pattern, have minimum power supply under this state and consume, but all devices all to close, turnaround time is longer.When entering this pattern, operating system exists all data in the internal memory by complete existing in the hard disk, and all units, interface (comprising internal memory) are all stopped power supply, and wait when start just directly from depositing the local directly complete internal memory that reads of these data.
5. state S5: this state consumes quite low power supply just as the software off-mode, operating system not affected what safeguard, need start again just can work.
Therefore, when computer system was in state S3, S4 or S5, all interfaces were stopped power supply, and made portable electron device to charge by the transmit port of a certain interface.That is to say, in the time of charging to portable electron device by computer system, must be with computer system power-on.Therefore, the function of system even if the user does not use a computer and when only wanting by universal serial bus (USB) interface, still needing with computer system power-on to cell-phone charging.Such mode of operation only can cause waste of power resources for desktop computer systems.But, for portable computer system, when using battery, effectively save the service time that electric power could prolong portable computer system as power source.Yet, in known technology, even if the user does not use the function of portable computer system, and only want that USB interface by portable computer system is to cell-phone charging, still need portable computer system is started shooting, not only cause the waste of power supply, also can seriously reduce the service time of portable computer system.
