When you "hibernate" your PC, the OS saves the memory state (including all the open applications, media files being played, files being viewed/edited, etc) into a dump file. This "dumping" takes about 5 seconds on my PC. Then, the PC shuts down, just like it would if you used the "Shut Down" feature. At this point, you can even unplug it from the outlet.

When you turn the PC back on, the memory state is restored by loading all the dumped data from the dump file. It is usually 3 to 4 times faster than turning it back on from a regular "shut down". All your open folders and documents as well as programs remain open, in exactly the same state as they were before the hibernation. Even that MP3 file will resume playing!


How to enable hibernation support:
Look in the Control Panel -> "Power", then under the "Advanced" or "Hibernation" tab.

I cant even get my PC to hibernate....:(

Look here if you could help...

Yep, I leave mine on all the time. I only reboot/shutdown for new Windows Updates, hardware installs, and the like. My little brother also leaves his on all the time, but has to reboot about once a day (a 486DX4 90MHz with Windows 95 isn't exactly the most stable machine for all the porn viewing he probably does..hah).

Which is about what a properly functioning system will take to wake from STR.

I dont know how to suspend to ram. I have the sleep button on my keyboard, i can set my settings to stand by or hibernate after a set time, but other then that im a lost little puppy.

I can't leave my PC on all the time because I have to pay for the d/\mn electricity! :) How can you all leave it on 24/7? Do your parents pay for it? :)

lol, making assumptions as to the ages of people are we. If i lived with my parents then i could probably make them pay it, but no, not the case. Ill call em up and ask if i can move back in though, always loved free power:p

Is there any reason to shut the computer off (or hibernate) other than saving power? Will it shorten the lifespan of my HD or something?

I have come to the conclusion that leaving on electronic equipment all the time is not necessarily bad. In fact, in the case of PCs, the opposite may be true. This is due to something called thermal throttling. Thermal throttling can cause materials (Especially metal) to expand and contract. Repeating this process over and over again could potentially be bad. Also, HDDs are rated in start/stop cycles. These are just small points, and I could be wrong. However, I haven't turned my computer off in a long time, except for necessary reboots. I don't even have my system go into suspend mode, I just have the monitor turn off after 15 minutes. It probably doesn't have much of an effect either way, so do as you will.

I asked because I had a PSU make a nice little explosion once.


I guess it's a matter of how paranoid you are.

Hibernate is available in WinMe/2k/XP only.


Hibernate is not available on WinME unless it is in other place than mentioned. I tried the control panel --->Power Options--->advanced, and there is nothing about hibernate there.

WinMe does support hibernate. In theory, no special hardware config or support is needed as the OS handles everything. In reality, it doesn't always work out that way so you may have some piece of hardware that isn't playing along.

Thats the os i have, how do you STR?

Go into your BIOS and make sure that STR is enabled. Either there will be an option to turn it on or off, or you'll pick from Sleep State S1/S3. S3 is what you want. Go into windows device manager, make sure any USB peripherals(kb/mouse/etc) are NOT set to wake the system from standby. Then instead of shutting down just hit Standby. Your system should appear to be off, no fans spinning or anything.

Note that all your hardware and drivers must support this standby state, if they don't it won't work. If your system powers down but the fans stay on, you've gone into the fairly useless S1(Power on Suspend) state instead of STR(S3).

What exactly is "Suspend to Ram" by that do u mean "stand by" mode on XP...if so then i use stand by mode all the time at nights. i just put the computer on stand by and the computer is off "WITHOUT ANY FANS OR ANYTHING POWERED". All i do is click on the power button once and baam..i am back in business in less than 2 seconds flat.

To get all of yours fans and everything to shutdown u gotta do to all ur USB stuff and other stuff that has the capability to bring the computer back up..such as keyboard, Mice, etc.

GO to the device such as keyboard from the device manager and click on the power management tab and unclick "Allow this divice to bring the computer out of standby"...

If u even have one device on the comp checked then the computer will not totally turn off fully. (meaning some of the fans will still keep on working). make sure u check all the devices.

I have found this to be the best way to get the comp back on in no time...

It's nice to have choices, and I use both Hibernate and Stand by on my notebook PCs on occasion. But claiming to save "countless hours" by using these features is a bit of an overstatement, don't you think? Good grief! My "slow" notebook takes a bit less than 30 seconds to get to the desktop. My fast systems take about 15 seconds. How many times a day, and for how many days, would you have to reboot the system to wind up using countless hours (or even one) in reboot time?

As I said, I'm all for choices, but I'm also for keeping a little perspective. Anyone who spends time on this forum (or any other) has to waste a lot more time just trying to decipher one or two badly worded wanna-be-a-h4><0r messages than he wastes booting each day -- with the possible exception of those who boot Windows 2000 Server variants. Those can be coffee-break-long ordeals for the impatient. On the other hand, how often do you reboot a server?

does anyone know how many kWh a relativly idle PC will burn in a month? say if its left on 24/7 and the only thing running is like AIM. This is with the monitor off.

obviously it would vary based on cpu/psu/ram/etc but does anyone even know how to figure it out?

Turn off ALL electric appliances and lights (Don't forget to empty the refrigerator and freezer.) and environmental controls, leave the computer running, go on a Med cruise for a month, come back, read the electric company's invoice. Works best if you plan your vacation to coincide precisely with the electric utility company's billing cycle.

It's not as efficient as purchasing a power meter and doing the calculations, but it's more fun.

With suspend to ram the computer does not totally turn off. Your comments above are specific to your machine/motherboard setup and generally you do *NOT* need to do what you say to get the fans to turn off.

The amount of power your PC uses when idle is actually OS dependent. MOdern OSes (read: not Win 9x/ME) issue a HALT instruction to put the CPU to sleep when idle and wait for an interrupt (usually the interrupt to increment the clock) to wake it up and check for any processes with something to do, rather than just going into a loop for awhile. Linux completes this check quicker and the CPU runs cooler when idle with it. Either way even with Win2k/XP, the idle power consumption is nowhere near the loaded amount. I would guess most of your PCs use less than 50W when idle including motherboard chipsets (but not including monitor). (

50W x 24h/day * 30days/month = 36 kWh/month
= less than $5/month even in NYC.

In contrast, the original Pentium 60 was considered a power hog and major heat source because it consumed 11W at peak (like 3W idle).

Suspend/Hibernate for a non-laptop just adds to possible sources of system instability. The power savings are negligable and there is no reason to not just leave the machine running.

Then explain how to set your USB devices to wake and NOT have the system fail to enter STR. Can you do it? It SHOULD work, but I've dealt with 7 totally different systems over the last 2 years and all failed the exact same way. In fact, I've never talked to anyone who can get it to work. My ultimate conclusion is that Windows has some bug where it cannot tell that your USB devices are able to wake from STR and so it either forces the system into S1 or gives an error that your device is stopping the system from entering standby. Even that theory has a hole or two, but the only other explanation is that 7 different mobos from 6 different companies have the exact same bug.

Works fine here on both my Dell's and my Thinkpad.

= less than $5/month even in NYC.

It works out to about $9.50 here in CA. Also, your calculations do not account for accessory usage and any associated cooling (e.g. if the system warms your room are you running an air conditioner to remove the heat buildup). I mention accesory buildup as I have a powerstrip that plugs into a free usb port, kills the speakers, printer, etc when the system goes into hibernate or standby.
