From a manual (http://download.gigabyte.us/FileList/Manual/mb_manual_ga-p55a-ud3_v2.0_e.pdf)

"Power On By Mouse
Allows the system to be turned on by a PS/2 mouse wake-up event.
Note: To use this function, you need an ATX power supply providing at least 1A on the +5VSB lead.
Disabled Disables this function. (Default)
Double Click Double click on left button on the PS/2 mouse to turn on the system."

If you have that enabled, and doubleclicking the left mouse button on your PS/2 connected mouse isn't working... I'd guess the power supply isn't providing the necessary power.  Doesn't look like there is anything special needed...

Ah...make certain ErP support is set to disabled?
"ErP Support
Determines whether to let the system consume less than 1W power in S5 (shutdown) state. (Default: Disabled)
Note: When this item is set to Enabled, the following four functions will become unavailable:
PME event wake up, power on by mouse, power on by keyboard, and wake on LAN."

Although, I would assume if this were set wrong, it won't work when you shutdown the machine from the OS either.

When you say you are powering off the system from the power source... if what you are doing removes all power -- yeah, no wake up events will function.  The motherboard has to continue to get a small amount of power.  If you are hitting the power button on the front of the system, it may be miswired and is removing all power.  If you are removing power at the power supply itself... unfortunately it's functioning normally.

well i want to start the PC from S5 state  , from other states it can resume itself , because in all of them motherboard draws some power ..


but when i press the switch on the wall  which is connected to the power chord ...
and then press the keyboard  it does not work ....

i want to start my computer  by pressing the mouse button after  a complete shutdown ( only with power from power source, mouse emits a red light)  


it can resume itself from hibernate ,sleep , standby etc ( because they are not complete shutdown)

I'll restate the scenarios:
1. Machine is not shutdown, but put into sleep, hibernate, or standby by the operating system -- double clicking the mouse does work to wake the computer up.  (This is expected, because, as the manual states - the motherboard continues to receive power.)  This scenario, however, is specifically what you asked NOT to hear about.

2. Machine is shutdown by physically removing the flow of power to the computer (in this case, pressing the switch on the wall) -- double clicking the mouse does NOT work.  (This is also expected, because the motherboard does not continue to receive power.)

3. Machine is shutdown by issuing a shutdown command from the operating system, at the end of which the operating system sends a message to remove power  -- double clicking from this mouse in this case does work per your message on 08/16/10 at 01:40 PM.  After reading a Gigabyte motherboard manual for a system which provides the functionality you mentioned, "shutdown the computer by selecting the shutdown option from the operating system" is the answer to the question, "how do i turn on the PC with a mouse by double click?"

I have one more question but

as you said  :

Machine is shutdown by physically removing the flow of power to the  computer (in this case, pressing the switch on the wall) -- double  clicking the mouse does NOT work.  (This is also expected, because the  motherboard does not continue to receive power.)

but then i again press the switch on the wall then mouse starts emitting a red light ...
the mouse is connected to the motherboard , if the mouse is recieving power the motherboard should also be recieving power .

So why dosent it work ????

I suspect the power supply isn't providing the power necessary after the system has been powered off to allow a mouse boot, but is providing the necessary power after a OS shutdown.  It isn't that the motherboard isn't receiving ANY power when the power is switched on, it's just not receiving the correct amount.  I was hoping to be able to look up the specifications based on the power supply model, but now that I look a little deeper, it doesn't appear that information is frequently provided.  I suppose you'll only be able to confirm with a multimeter.

A useful device used to detect and confirm the current, in this case the supply of 1A current on the +5VSB lead.
