1, ACPI Concept

ACPI: Advanced Configuration and Power Interface

There are different modes of ACPI:

S0 to normal.
S1 processor to stop working.
S2 CPU stopped.
Also memory outside the S3 components stop working.
Add your memory S4 data on disk, all parties to stop working.
S5 closed.

ACPI power management to use hardware and software can be fully compatible with the ACPI.

If you problems in use, you can try the latest update acpi.sys file.

In addition, the ACPI hardware support is essential. Food chassis 5 volts to the motherboard at the same time, we need to have stabilized over more than 720 milliamps to a computer in a short sleep time "Summer awake.

The program can be obtained by choosing the management of energy supply, program management power is the power of computers to use a set of values. Windows 2000 provides three types of program power management Default (if open notebook or Laptop Computer home office / study), the user can also configure your own computer standby or turning off the Hard Drive and monitor the time to wait.

2, ACPI and APM Compare

APM 1.0 and 1.1: the implementation implemented by the BIOS Power Management;

APM 1.2: System operational definition of time of power management BIOS is responsible for implementation;

ACPI: data collection hardware BIOS to define solutions for power management the operating system responsible for the implementation.

APM is a software solution, therefore, with the operating system, but ACPI is a standard Industry, including software and hardware specifications.

1) How to determine the system is in S1 or S3?

A: S1 standby, ACPI, only the processor to stop working, other teams are still in the state. The ACPI S3 (BIOS-> Power Management -> Put the RAM, among other teams are out of state memory. Therefore, to determine the system is S1 or S3 mode The easiest situation is carefully observing system: In the S3 state, the team has ceased operations, even if the button down the unit can not open the door of the unit. In the state S1, the optical drive door is open. In addition, the S3, the system is quiet, all the fans are stopped. This point system can not wake up from the keyboard. manual method can be awakened the front Panel Power button.

2) To achieve STR, why not turn off after shutdown?

Answer: The function STR is off, will the system operation information in memory, the next time you start to read information directly from memory, and the return to the previous stop. Its advantage is to start very quickly, and can keep working conditions. The disadvantage is that even after shutdown, you can not cut the current power. Since the data in memory is lost once the cutoff current.

3) At the end of Win2000, display "You can now turn off" instead automatically close ATX, how do I do?

Answer: You can try the following steps: choose "Settings / Control Panel / Power Options / Power Management "If the computer supports the Advanced Power Management, then select" Enable Advanced Power Management Support ", then PowerdownAfterShutdown HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsNTCurrentVersionWinlogon half by 1 if the machine is not compatible with Advanced Power Management, then, unfortunately, that in the closed system, the screen can be turned off now? "Had to hand off the power.

4) do not care no "Close Windows dialog box" Allow the computer to sleep loss, and ask how to restore it?

A: In general, this kind of problem, if you reinstall the drivers for the motherboard, restart the future should be able to resolve the problem, you can also "Control Panel / System Device Management /" in support of the administration "Advanced Power" wiped and restart the machine as the Windows 2000 system can also be invited to re-install solve the problem.

supply and video card please help?

I just bought a Logisys 575W 20 +4 pin Dual Fan Atx Power Supply - SLI Ready to Amazon and a Nvidia Geforce GTX 260 OC 896MB GDDR3 PCI Express 2.0 Graphics Card Maxcor and I was wondering if the power is sufficient to operate Also the video card I have 3 GB of memory on my pc and 2.8 GHz with Windows Vista Home Premium 32-bit my pc is a Dell Xps 400 and 160 GB and I I have two hard drives and rewriteable DVD-ROM by one and a floppy Disk Drive please help! Thank you!

Your PSU should Logisys work, but to cut a little narrow. I glanced to the specifications of your diet, and it is rather low, with only 25 amps on the rails 12 V: http://www.newegg.com/Product/Product.aspx?Item=N82E16817170017 GTX260 draws a maximum of 15.2 amps on the +12 V. With his power from 10 amps for the rest of your system, which leaves a very thin margin of safety. I recommend a diet high +12 V rail, 33 amps as this: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139003 And if want GTX260 SLI two of these is the power that is achieved, with 52 amps on the +12 V: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139005 Hope this helps.
