Windows XP Standby and Hibernate Problems Solved (finally … I hope)

Category: Household,Save Electricity,Technology,Tips – Tom Harrison – 9:05 pm

Standby or Hibernate Control Panel WidgetWindows XP will not go into standby or hibernation in many cases. As I learned a few weeks ago after installing my Smart Strip and measuring the result with my Kill-A-Watt, when the computer is on, it uses a lot of electricity. But my Windows XP PC would not go into standby mode or hibernate. I believe I have finally solved my stand by issues.

(Update, 10/2008: See comments and responses below for troubleshooting and a updated windows hibernate and standby problem post I am maintaining as further information becomes available)
(Update, 2/2009: I am going to try to highlight notable comments in the comments thread below, as there are some good ones)

When the computer is on, it uses around 68 Watts. With the Smart Strip, when the monitor is off, other devices are also turned off, but it still draws 28 to 30 Watts. Standby gets me down to almost nothing, Hibernate gets me to nothing. Now my computer goes into “suspend” (sleep, stand by) all by itself, just as it’s supposed to. While I have tried to be good about turning the computer off (actually, hibernating manually), nothing beats automatic.

What are Suspend / Sleep / Standby / Hibernate Modes?

If you don’t know, Windows Standby is a very cool feature (even if you don’t care about saving electricity). Suspend, Standby, and Sleep all mean pretty much the same thing. When your computer is in Standby, it remembers everything you are doing. You don’t have to close your browser, or game, or iTunes or email program or anything. The monitor turns off, and the computer uses much less energy — just enough to remember.

Touching the keyboard or mouse wakes the computer from standby: the screen turns on, the disks spin up and connections reconnect — all automatically, and all in a matter of a second or two. It is brilliant! Of course Macintosh also has this feature (and I am sure it always works on a Mac :-).

Hibernation is pretty much the same, except it uses the computer’s hard disk to store everything that was in memory. Because it is on the disk, the computer can turn off completely, and use no power at all. Hibernation takes about 10 or 15 seconds to complete on my computer, and about 20 to resume, so it’s not as snappy as Standby mode.

I almost never shut down my computer. It takes a great deal longer for everything to start from a clean start, and then you have to open up all the programs you want to use. For me, this can take 2 minutes just to get to the point where I can start opening web browsers, and all the other programs I use, which usually takes another couple of minutes. Resuming from hibernation takes only 20 seconds to end up in the same place.

Using the Power Options in Windows (XP or other versions)

Windows XP Power Options Control Panel SettingsEven better, you can set your computer to do 4 things that save power, based on how long since you have used it.

  1. Turn off the monitor (screen) (20 – 40 watts when on, maybe more)
  2. Turn off the hard disks (1 or 2 watts when on, maybe)
  3. Suspend, or Standby (about 5 watts when in this mode)
  4. Hibernate (computer is off: no watts!)

Open the Power Options window by clicking Start, then Control Panel, then Power Options. If you don’t see an option to Hibernate, there’s a tab near the top of the window that will let you “Enable Hibernation”, after which the option should be available.

You can set how long you want before each mode kicks in. Notice that on my power settings, since I have a laptop, there are different settings you can use for when plugged in versus when on batteries.

Bottom line: when it works, it’s awesome.

But standby and hibernate don’t work all the time

If you make the settings above, but your computer doesn’t turn off at the appointed time, as was my case, I hope your patience and perseverance didn’t have to be as extreme as mine :-). I have been working on this problem on and off for about a year — I thought I had solved the issue, but then it started not working again … or maybe it never was working.

It is simply unbelievable to me how little help Windows gives you in diagnosing these problems. In my real job, I am a computer systems and software engineer: I know how they work, and how to do what could be dangerous things without messing things up too badly.

So the first resource I used was this link from Kelly’s Korner which is a well-maintained list of various issues people have reported over time. I tried a lot of things, but none of them worked for me.

One tip: set the monitor timeout to 3 minutes, standby to 1 minute and hibernate to 2 minutes so you can see if things work in the least amount of time. I set my watch timer so I would know when to give up.

Another tip: write down what you do. I wish I did, since I am not exactly sure which of the things I did that actually resolved the problem.

Tip #3: Work on not starting programs automatically first. There’s a nice tool (free) called nCleaner that does several things. One of them is to allow you to see and change some of the programs are getting run when the system starts. Two good things happen here: 1) you can usually find a number of unnecessary programs that take time to load and use up memory unnecessarily, and 2) you’re going to be rebooting a lot, so the faster things start, the better.

Tip #4: You would be amazed at how much crap gets loaded by default. Then computer manufacturers cut deals with various companies to install their programs, or trials, many of which also load some annoying things when they start.

Why Standby and Hibernate Fail

The main thought about why standby fails is that there are bad “drivers” (the software that makes things like mice, keyboards, screens and other parts of the computer work). They need to cooperate in the whole game of turning off when told to. The first thing to do is use Windows Update to make sure everything is up to date (just recently the latest “service pack”, #3 was released). (Start » Programs @raquo; Windows Update … or possibly Microsoft Update).

I also went to Dell and looked for updated drivers for my system. None of these things helped me. I was amazed at how … lame Dell’s site was

I tried disabling devices that I knew I wouldn’t need at the moment (DVD drive, wireless network connection, various other things). I unplugged all the USB devices. Go to Start » Run » and type in devmgmt.msc. Expand groups of “devices” and right click on the ones you think you won’t need, clicking Disable. For me nothing here helped.

Then I got rid of everything out of the Start » Programs » Startup folder. Mostly these were programs that kind of “warm up” programs so they seem to take less time to start when you want them to load. Grrr.

Then I uninstalled as many programs as I could that I was sure I didn’t need. This is a little tricky, but if you aren’t sure what a program does, Google it. Go to Start » Control Panel » Add or Remove Programs. Keep in mind that most programs can be easily reinstalled (except for ones you have to pay for, and actually use). Go wild. Use the nCleaner program afterward to finish up all the uninstalling that the actual uninstallers don’t do.

So in my case, the main culprit seems to have been some software called Wild Tangent whose purpose is to make 3D Games played on Yahoo work. Which is great for all the people who play 3D Games on Yahoo. Me, I play my 3D games in places that actually have three dimensions, like my living room, or on the field with a Frisbee. Yahoo, not so much.

And after this (I think) my problems were solved. I could reliably see my computer go into standby mode, then a minute later hibernate. Hallelujah!

All Systems Go (because All Systems Stopped) … but not so fast

I watched in admiration and glee, several times as my computer, all of its own accord turned itself into a non-energy sucker. And just as I was getting complacent, I was slapped in the face with the reality of things.

I like music, and we are an iPods and iPhone kind of family. So I use iTunes. But I am also a geek, and think that things we all use should be in a central place, so have a computer in our broom closet that does things like keep our photos, music, TiVo’d programs we like to keep, Virtual CDs (so all those games we buy on CDs can be used without having the CD on hand), and a few other geeky kinds of things like that.

So it turns out that when iTunes is open, or perhaps any program that is using a file located on a remote computer (like the one in my broom closet), Windows decides that’s reason enough not to shut down. No warnings, no errors, no messages, no indication whatsoever that this state has prevented standby, just … nada.

Quick note for people looking to diagnose standby/hibernate issues: files open on remote computer seem to prevent standby.

And iTunes starts every time I plug in my iPhone or an iPod to charge, so that it can sync up and back up whatever it needs to. And I listen to music during the day when I am working at home on And by default, iTunes nicely stays in view in the alert area. So, it’s pretty much usually on. So now I have to shut it down in order to make my computer shut down automatically. Foiled again … sort of.

Naturally, I am highly inclined to blame this on Microsoft. Except it seems like there may be similar issues with Macs, as we’re conscious of this at work, too, and are using Mac’s there. Harumph.

Ok, so anyway, I am now pretty expert in diagnosing standby and hibernate issues. Post a comment if you have one. But remember: my goal is to solve these problems so your computer can save energy.


  1. I have to report that my XP goes nicely in hibernation mode ONCE after a fresh system start. (Referring to jqs.exe disabling).

    => Fresh Start #1 => Hibernation after X min
    => Start #2 => NO hibernation

    Just wondering what is different after hibernation.. There is something that is nagging the system not to sleep. Argh..!

  2. Tom, this is a super post, and while I have not read all of the comments, I have gotten a huge amount out of the reading. What I would love to hear from you is some comments related to using an SSD instead of the standard HD. I have both running on my system, and there are various tweaks that give you an optimization, one of which is to use a RAM drive for temp files. That, plus the SSD drive now give me a super fast startup of both the system and major programs. I keep most data files on the regular drive and most programs & the OS on the SSD. While I know that the RAM drive precludes hibernate, I am working now on at least going into standby to keep down power consumption. I am sure your input and additional advice will help me get to a solution.

    Again, as noted by others, thanks for your hero status on this worthy cause to help us lower our carbon footprint!

  3. Tom, I have a Dell Dimension E510 with XP Media, with Windows auto update. I have only switched my anti-virus from Avast to AVG in the last few months.

    The Standby and Hibernation were working fine until about 2 weeks ago. One day, Standby stopped working – would not activate – so I went into Power Mgmt and selected hibernation and it worked fine for a few days. Then it stopped. I went back to Power Mgmt and selected another time interval for Standby and it worked fine for a few days. Now, regardless of the time interval or whether Standby or Hibernation, is not activated.

    I looked at the SartUp programs and do not see anything different or not necessary there. Assuming that there is a software not allowing it to be activated, how can I check it out. I would appreciate your help on this, to avoid having the pc on when not in use.

  4. My problem is that standby seems to be working fine – except that the monitor turnoff never turns off the monitor. Any ideas?

  5. I have an HP Pavilion A556X – just acquired second hand. I updated all the Windows updates and drivers and had this problem of not being able to go into standby mode. I got a message saying my keyboard driver was the culprit. As it turns out, it was Adobe Type Manager (possibly conflicting with the keyboard driver) since standby now works after uninstalling ATM and rebooting the computer. I now see it mentioned as the solution in comment #56 so I just wanted to second that solution.

  7. My Gateway laptop with XP stopped going to stand by either plugged in or running on batteries, although it did go to stand by with when I closed the lid. So hardware was not the issue. I read on of the posts above and downloaded Glary Utilities, ran it, nothing happened. Installed and ran nCleaner. It removed other stuff which Glary did not, but the same story. Then I rebooted the laptop and it started working fine. So definitely one of the programs or both of them solved the problem, at least for me. Note: I unchecked all extras both of these programs offer during installation.

  8. Hi,

    I just came upon a different problem. We have a media pc to play blu ray and standard dvds running xp and in the last two weeks after years of no problems shortly after turning the pc on, but never more than a minute or two it crashes saying “preparing to go into standby”… any ideas on what may be causing this problem. Once again just using it as a media pc to watch tv or play dvds and no internet.
