. . . anyone knows, why it isn't waking on USB . . .? Or does anyone has a clue why it isn't rebooting from S3 correctly?
The SR-2 can reliably sleep and awaken. I use this function multiple times per day. The S3 function works regardless whether using IDE/AHCI, SATA II/III system drive, or stock/over-clocked speeds. How reliable is it? I can only tell you my experience that I only had (perhaps, recall) 3 failures from daily usage between the period beginning in October to today. So I regard this as very reliable.
If you need to set up the sleep function quickly, I recommend that you enable HIBERNATE from the operating system. Hibernation works reliably with little effort. I used hiberation for several weeks when I first set up my system. But the most satisfying experience is obtained using S3. The SR-2 goes to sleep and wakes up quickly. Also, the energy consumption while sleeping is only about 6 Watts, depending on the hardware included.
S3 sleep does take a little work to set up. You need to change settings in the BIOS setup menu, in the POWER OPTIONS in the CONTROL PANEL of the operating system, and sometimes also in the DEVICE MANAGER of the operating system. Then after you get it working, you got to trouble shoot problems, e.g., typically, the computer awakes spontaneously or one of the hard drives never awakes. But the problems are correctable and the work you put in correcting such problems is well worth the effort. (If you are using Windows, the OS provides many useful diagnostic routines.) The following lists the main settings you need to make.
BIOS settings: Set SUSPEND MODE to S3 (STR) and enable the USB Device wakeup from S3/S4.
POWER OPTIONS: The three main options are the HARD DRIVE (select NEVER turn off), the USB (select ENABLE selective suspend setting), and PCI-E (select turn OFF link state power management).
DEVICE MANAGER: Examine three device types in the operating system device manager: the keyboard, the mouse, and PCI-E. Each will have a POWER MANAGEMENT TAB. Select the tab and then select "allow this device to wake computer".
Additional information:
1- When I used an old graphics card, the S3 function didn't work (although HIBERNATE worked fine). Then when I installed a new one, S3 function worked immediately. I am guessing that the graphics card could affect the S3 function.
2- Hard drives (particularly the "green" ones) sometimes will not awaken from S3 sleep. If you encounter this problem and you are using Windows 7, Microsoft has a fix for this. I provided the reference for the fix in another post several weeks ago.
3- Application software can sometimes create problems for S3. For example, on the SR-2 board, the software might not make provisions for waking up a SATA III drive. The problem arises from the fact that the SATA III drives are currently controlled by a different device than the SATA II drives. Software designed several years ago might not detect a motherboard has multiple SATA controllers. Also note that turning off the software is not sufficient. The software needs to be stopped. For example, if you ran and exited from a popular software called ArgusMonitor. Enter the command prompt and type "sc query ArgusMonitor". Then look at the STATE. The STATE must = 1 or STOPPED in order than it doesn't affect sleep.
I probably forgot something. But I'm sure someone will provide additional information. Good luck and have fun -- RP
