Sleep

post #1 of 13
Thread Starter 
Quick Question . might be a stupid one but hear me out .i just hope im in the right forum

i recently got a kill-a-watt and noticed something . when my pc is off it always pulls 7watts . when i put my pc to sleep mode it also pulls only 7 watts

now heres my questions . what components stays on and doesnt even pull a single watt but enabled my pc to go from about 2 mins boot time ( off to on) to a 3 seconds boot time (sleep to on)

with that beeing said , would it shorten my pc (or any of its components) having it remain in sleep most of the days rather then off??

I don't know why it's pulling 7W when you shut it down completely unless you have a solid state drive. I guess. I don't know.  Is it just your PSU's power cable that's plugged into the Kill A Watt?

 

Are you asking why it boots faster from sleep?

Your comp is like in a trance in sleep mode so the apps opened etc are still there so when you hit a key it wakes up where you left it, and no, your comp on or of, or sleep mode does not make much or any difference to the life span.

It was different case years ago i believe, but electronics have changed now - less surges and spikes biggrin.gif

As for the meter it may not be as accurate at 7 watts - hardly a draw of power and it takes a minute bit of current to signal out of sleep mode - think as like in tv and dvd players and so on thumb.gif

There really isn't much difference between and S3 sleep (the sleep you are referring to). The only thing that is powered in S3 sleep is the RAM, which is not going to draw enough to be noticeable really. Sounds like both of them are either under the kill-a-watts sensitivity floor (which would appear to be 7W), or the normal power-off draw is also 7W. Even with the system off the PSU is still supplying standby 5V power to the motherboard, as evidenced by the surface-mounted LEDs that some motherboards have turned on even when off. The PSU has to be supplying some power all the time so the soft power-on switch can work.

Edit: Just checked mine, 3W in sleep and 2W turned off.

was gonna check mine as i have a meter but it looked so nice a sleep on the floor beside me that i did not want too wake it up biggrin.gif

Watt ! biggrin.gif

Seems normal to me. Even when your PC is off, it's still using a small amount of power to maintain essential clocks. If that 7W includes your monitor, then you're at about the lowest load possible.

 

To relate, have you heard of 'ghost load?' It's the power consumed by electronic components even when off or standby. Research that a bit and you'll get a more complete description.

I don't think that's true, the computer still polls the usb ports and everything else that can wake it from sleep.

Not in S3 mode. It's completely powered off except for the memory. The only thing that can bring it out of this deep sleep is the power button.

Yeah, that's right - it's got to be keeping the LAN alive, along with the keyboard and USB at least. That's all gotta be pretty low power though, since it's all running of 5V standby.

You might be thinking of hibernate, S3 (at least the common suspend-to-RAM implementation) can wake up from mouse or keyboard.

No. When I put my sig rig to sleep. the only thing that can bring it out is the power button. Now, if I put it in Stand By mode, then yes, the mouse and the keyboard are what I need to use (except, I don't have Stand By as an option for some reason).

 

I know the difference between Hibernation and Sleep. I don't need to be schooled in such basic things. ;)

 

Edit: I forgot: if you have a PS/2 keyboard or PS/2 mouse, then yes, those will bring it out of Sleep Mode. I have a USB mouse and a PS/2 keyboard. The keyboard brings it out, but the mouse does not.
