Does windows 7 sleep mode use power?

If I remember I'll check it out later on or tomorrow.

I have got mine so when entering sleep it doesn't store the mem on the hdd aswel and this is mainly because I have a ssd drive. But to be honest I don't really need the info stored on the drive aswel because I have a UPS, that will keep things ticking over during powercuts.

I have a ups, but only on the server. When it goes out the server shuts down as normal. ~Saves corruption!

I have just started sleeping my main PC, even though I close down all applications and make sure everything is saved. Just in case! But means I do not have to wait 15 seconds for it to boot up.

if you unpluged it from the wall it had to be reboot from hibrid sleep
because the power was cut from sleep mode
a laptop would stay in sleep mode till battery ran out , but a desktop will lose power as soon as you pulled plug from the wall

"Hybrid sleep is designed primarily for desktop computers. Hybrid sleep is a combination of sleep and hibernate—it puts any open documents and programs in memory and on your hard disk, and then puts your computer into a low-power state so that you can quickly resume your work. That way, if a power failure occurs, Windows can restore your work from your hard disk. When hybrid sleep is turned on, putting your computer into sleep automatically puts your computer into hybrid sleep. Hybrid sleep is typically turned on by default on desktop computers."

I understand that, as I also use sleep on my laptop. However, whether it's sleep or hybrid sleep, my computer still boots instantly when I use it, even after it's been unplugged for quite some time.

I tried setting mine to Sleep, but it always crashes. I had around 4-5 crashes in 2 days all in Sleep mode. Posted a thread here about it, but it went nowhere.
It's a shame, I have *always* used sleep- but now have it disabled :<

I've built a lot of systems over the years for friends and myself and one of the most sensitive indicators of a marginal overclock (and ram timings) is crashes on resuming from (S3) sleep mode (even though general use and benchmarking says it is stable). Might be worth testing with some relaxed settings.

Back to the OP, I use S3 sleep extensively during the day whenever I am away from my PC as it does save a lot of power over time. Also setting the display and hard drives to power off after a short period helps. Always power off at night though, if only because I don't like sleeping with too many electrical devices still "active".

I never had it overclocked. (Still do't, waiting to decide on what cooler to use before I upp the clocks.) so, it's still an i5 @ stock, with only the ram changed to 1600mhz. But that's the Ram's stock anyway so..

I've got a power meter

After lunch I'll test it out
