please try to load your bios defaults & check the same, or remove ur CMOS bettery for ten mints & try.
S1 and S3 aren’t just ’standby’ and ‘hibernate’, they are different *types* of standby.
S1 is what most people have as standby– your monitor turns off, cpu goes into a type of sleep, hard drives spin down. fans keep going etc, not great. move your mouse and your hdd spins up again.
hibernate(S4) – saves your memory to hard drive and turns the PC fully off. doesn’t use any power, but not that fast at turning back on.
S3 is the best of both; it turns almost everything off (but the ram, and WOL stuff), but will come back on to full use within 5 seconds. usually have to press the power button to turn it back on.
Just have Windows Task scheduler run an “empty†task a few minutes before A/V s/w is to do its thing and set it to wake your computer to do it. Alternatively, if there is a task already setup for A/V s/w, then try to see if having it wake your computer up to run will work. In my case, it would not execute the task upon wake up. Thus, the “empty†task. Also, you’ll need to make sure it’ll execute the task(s) without being logged in. You can create a task to run after a couple of hours (or whenever A/V s/w finishes) that will put your system back into S3:
“rundll32 powrprof.dll,SetSuspendStateâ€
Should be the command line statement to do the action in your power options under “Do this when I press the Sleep button on my computer.†So, make sure that option is set to standby.
check your S3 state by a program called Sleeper by PassMark (free for personal use,…- I didn’t detect any spyware) to verify the S3 sleep state.
GUIDE ON S3 ACPI for general users:-
S0 = Full Power-On. The computer is operating and fully active. Even though this is the case, Laptops and Desktops can still shut some devices off or put them in low power states (So in Windows Power Management, when you shut off monitors, hard-disks, etc, you are still in an S0 State.
S1 = Light Sleep. This level will clear your processor memory (caches) and will stop running operations whiles most extra devices like video cards and hard-disks will be put into low power mode or shut off entirely…Fans will either continue to run or go into a low-rpm mode. This state is no longer very common as the CPU and RAM must remained powered up, but not under load. Power savings in this state are minimal.
S2 = Sleep. This mode is identical to S1, except the processor is fully shutdown, This however, is not used by most systems.
S3 = Standby. This is one of the most effective power-savings modes since it allows you to maintain some degree of quickness in resuming work, while also decreasing power usage. ALL components are shutdown, with the exception of the USB controller, NIC, and RAM. The RAM will continue to be run in low-power mode as to maintain your current operating state. Waking up from Stand-by takes roughly a few seconds, as most operating systems store their state solely in RAM. WARNING: If you lose power while in S3, you will lose any information that was not stored to hard-disk before going into stand-by. If you wish to prevent this, or lessen this effect, disable Disk caching/buffering. (Wikipedia)
S4 = Hibernate. This is the closest to off, since your computer is actually turned off. The operating system will store RAM to your hard-disk, and then completely shutdown your computer. When it resumes, it must move the RAM from your harddisk back to RAM to resume. This is the best power-saving, but also takes significantly more time to resume operations.
S5 = Soft-Off. This is the state computers go into when most users turn their computers off. It uses very slight amounts of power in order to operate components used to wake up the computer.
Off. The computer is electrically inactive. This occurs around 20 to 30 seconds after a computer has been shutdown and unplugged. The only component to remain on is the Real-Time Clock and CMOS Memory chips.
How Do I enable this S3 Sleep State?
If you are lucky, your computer might already be configured properly to enter S3 Standby mode. Why don’t you check and see. Click your standby button (Start – Shutdown – Standby). Now, once the computer is in standby, check the fans on your computer. Are they still spinning? If so, you are not taking full advantage of S3 standby mode. S3 standby mode turns off all the components inside your system except the memory using as little as 1.8 watts. S1 standbymode just puts your components in low power modes and uses only slightly less power than a computer that is in the on state.
If your computer is already configured correctly and your fans have turned off, then you can continue on to the section called How to use S3 standby states when you need your computer to be ALWAYS ON.
If your computer’s fans are still spinning you can try some of these options:
Check your BIOS settings: Make sure your BIOS Power Management settings are set to S3 standby. Unfortunately if it is not set to S3 when windows was installed, Windows will not install the correct settings to allow the computer to sleep in S3 mode. However, just changing the option in the BIOS will override the windows setting on some computers and you may enter the S3 sleep state anyways.
Are you using a USB keyboard or mouse? This may be holding you back. For fear of allowing a computer to enter a sleep state that it was incapable of resuming from due to incompatible USB devices, Microsoft decided that if USB input devices were present, it would not allow S3 Standby mode. Fortunately this is easily bypassed through use of a registry entry. Just open regedit and enter the following registry entry as described in this Microsoft Knowledgebase Article:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\usb
“USBBIOSxâ€=DWORD:00000000
Entering this registry key, then rebooting should allow you to enter the S3 sleep state even while using USB peripherals in Windows XP.
If your computer enters Standby mode, but then immediately starts back up, your USB devices may be giving you problems, check your computer’s BIOS settings and disable (or enable) USB power on options, changing these settings can allow your computer to function properly.
Now if you are lucky, your computer is now configured for an S3 Sleep state. Congratulations!
Now you can select a power profile in the ‘power options’ control panel icon that allows your computer to enter standby mode after a user specified number of minutes!
And now We can finally move on to:
How to use S3 standby states when you need your computer to be ALWAYS ON
This section of the article will cover how you can make S3 standby states viable when a computer is acting as a file server, a remote access point, vnc host or any other kind of network activity. In my case, I have two computer, one is a media center computer in the living room, the other is a more powerful Core 2 Duo machine which has several large hard drives which serve as a repository for videos media and music, which need to be accessible on demand. I have figured out a few tips allowing the computer to wake from an S3 state and serve the files or provide the access required without any need for “magic packet†software or any other utilities other than windows itself. It simply wakes whenever it senses activity routed to it’s specific IP address. Here are the steps you can take to configure your own machines:
I have found that the most reliable way to make this work is set static IP addresses on your local network. This means that rather than having the router automatically assign an IP address on your local network, your network card decides on a static or constant IP address. This makes routing traffic around on your ports much easier. Follow these steps to set a static IP:
Navigate to the Control Panel: Doubleclick on Network Connections
Right click your Local Area Network: Choose Properties
Select Internet Protocol (TCP/IP)
Click Properties.
Set your IP address manually: (ip address generally can be whatever you want it to be within certain limits, the subnet mask, default gateway, and DNS settings should correspond to your particular router. Check your router manual for more information)
Once you have made your changes, click ok and allow your network adapter to reconfigure itself and reconnect to the network.
Test your network to see if you still have connectivity by pulling up a browser or checking network accessibility.
Now we can move on to configuring the computer to wake up when it senses trafic on it’s static IP address.
Boot into your BIOS, make sure all WOL and network wake up options are enabled. Refer to your manufactuer’s motherboard manual.
Boot back into Windows: Navigate to the control panel: Doubleclick on Network Connections
Right click your Local Area Network: Choose Properties
In the first box it should show your network adapter. Click ‘Configure’
Navigate to the ‘advanced’ tab: Select ‘Wake Up Capabilities’
Every network device varies a bit, you want to enable all capabilities, choose ‘both’ or ‘magic packet and wake on pattern’
Click the Power Management Tab: check the box that states: “Allow this device to bring the computer out of standbyâ€
Once you have selected these options and rebooted, you should now have set your computer up with a very powerful configuration. You can now allow your computer to go into standby mode, yet whenever your network adapter senses any activity on your specific Local ip ,it will quickly resume from S3 standby and perform the functions requested. As soon as the network is not being utilized, your computer will return to standby after the allotted time you have set in your power options settings.
