No Standby and Hibernation, how to do?

[Wai_Wai]

1. Since my motherboard / BIOS does not support (Standby) and (Hibernation), is it possible for me to download some software to enable the above functions? If so, where? Or is there any workaround?

My motherboard is Asus A7N8X-VM.

BIOS is already updated, the newest version.

2. Does anyone know what the following means in power management:

- S0

- S1

- S2

- S3

- S4

- S5

*new*

3. My monitor will not automatically shut down when it is idle more than the given time. I tried it even if I just started Windows and open no programs. What's wrong? How to solve?

1. Please specify what motherboard you have. A BIOS update might solve this problem.

2.

- S0

- S1 standby

- S2 standby

- S3 standby

- S4 hibernation

- S5 poweroff

In Standby, the context of RAM is preserved by putting the RAM in

self-refresh mode, which uses a little energy.  In Hibernation, the

context of RAM is preserved by writing it out to a file on the disk and

then the machine is turned entirely off, using no energy, other than

that required to write the file.

On resume from Standby, the BIOS has a chance to run a little bit of

code.  On resume from hibernation, the BIOS goes back through a complete

boot.  The BIOS can be aware that it is resuming from hibernation, and

cut out some of the boot steps, but few BIOSes choose to do that.

From a WDM driver's point of view, there are five "S" states.  S1, S2

and S3 are all varying levels of "standby."  S4 is hibernation.  S5 is a

full power-off, with no context saved.  The differences in S1, S2 and S3

matter only when your hardware needs to wake the machine.  Some power

planes may be preserved in S1 but not S3.  (No motherboard designer

bothers to implement S2.  And many don't even support S3.)  So look at

your device capabilities structure (returned by the bus driver in

response to IRP_MN_QUERY_CAPABILITIES) if you need to know.

hibernation in Win2K and WinXP.)

Thanks a lot.
