Description
Technical field
The present invention relates to computer, more particularly, to a kind of logger computer is truly started shooting the method for service life.
Background technology
Do not have preferable method at present to obtain true start service life after dispatching from the factory for the computer.User is to meter
Calculation machine is guaranteed to keep in good repair, and simply determines whether to reach term of service with the invoice time.Such as, the guarantee period of a computer is set to
1 year, but actually have two kinds of users：One kind is everyday using computer, and usage frequency is at a relatively high；Another kind is to be rarely employed
Computer, then the true service life of this two computers is certainly different.Make in the true start obtaining computer
In the case of the life-span, you can the maintenance cycle of setting computer：Subscriber computer or using the invoice time as guarantee
Phase, or using the true start life-span as the guarantee period, which arrives first, and just the guarantee period reaches at last.Automobile industry is to adopt class
As guarantee period computational methods.
In addition, user is when buying computer, due to not knowing the true start use time of computer, often
Misgivings, worry that whether can buy others reprocesses machine.If computer can show true start service life, also can help
User dispels misgivings.
ACPI (Advanced Configuration and Power Interface), that is, advanced configuration and power supply connect
Mouthful.ACPI is in operation following several modes：
S0：Normal mode.
S1：Standby mode, only CPU quit work, and other equipment is still in powering state.
S2：CPU closes, and S1 is about the same.
S3：Standby mode, system is switched to after this pattern, and except internal memory, the power supply of computer other equipment all will be interrupted,
Only internal memory relies on electric power to maintain data therein（Because internal memory is volatibility, as long as power-off, data just without）.This
Sample is when hope recovers it is possible to be directly returned to standby front state.This pattern non-fully not power consumption, if therefore
Power supply occurs extremely in the standby state（For example have a power failure）, then just can only turn back on next time, front not preserve so standby
Data all can lose, but the resume speed of this pattern is the fastest.
S4：Park mode, system is switched to after this pattern, and the data in internal memory can all be dumped to firmly by system automatically
In a hibernation file on disk, it is then cut off the power supply to all devices.So when recover when, system can from hard disk incite somebody to action
The content of hibernation file directly reads in internal memory, and returns to the state before dormancy.This pattern not power consumption completely, is not therefore afraid of
Abnormal electrical power supply after dormancy, but cost is to need one piece and physical memory hard drive space of a size（Present hard disk across
More TB rank, big capacity hard disk is more and more cheap）.And the resume speed of this pattern is slower, depending on memory size and hard
Disk speed.
S5：Shut down computer.
SMI：System Management Interrupt system management interrupt.
