    Computer Sleep (Vista Home Premium)

    Under Power Settings I set the monitor to go off in 15 minutes or so; and the computer to go to sleep in 3 hours. But the computer doesn't seem to shut down (at least the blue light showing it's on continues to glow). Why doesn't the sleep mode work?

    Thanks

    Are you sure you are not mixing up Sleep and Hibernation? In Sleep mode, power is still required. See:
    What is the Differences Between Sleep (Standby) and Hibernate in Vista?.

    Yeh: that's it Leif. So, given that, is there any good reason on a desktop computer that I leave on all day (I usually shut down at bedtime) to have it go into the sleep mode? Which is preferrable? (It doesn't sound from the article that Hibernate would be particularly good, apart from saving some energy--which is getting more and more important! And along the same line, what then is happening on my Laptop (Dell) when I just close it down bhy closing the cover?

    The effect of closing the cover is controlled from Control-Panel > Power Options > Advanced

    I just realised that this is a Windows Vista thread, so the Power Options wil be a bit different. I assume there is still a similar option but I don't have a system running Vista here.

    Re: Computer Sleep (Vista Home Premium)

    To be honest, I would say it's a matter of personal preference weighed up against environmental pros and cons. I am inclined to believe computer hardware, hard discs in particular, have a longer life span when left running as they are not subject to variations in temperature or stresses involved in start-up and shutdown. (You'll find this discussed in various threads in the Lounge <img src=/S/smile.gif border=0 alt=smile width=15 height=15> )

    Again in my view, hibernation is only practical with laptops where you want to serve battery power - with a pc you may as well save everything anyway. As a rule of thumb, I would suggest you work on the basis that if the working day of your pc is more than 12 hours, you may as well leave it on 24/7. A waste of energy, yes, but probably less of an environmental impact than scrap pc hardware (and it's packing and shipping!). Monitors/screens, printers etc should be powered down when not required.

    I think Stuart has answered you question regarding your laptop. It may be an out-of-date view, but I tend to think of laptops having a shorter lifespan than pc's and so I tend to shutdown my laptop whenever I'm not using it. (This is more for practical reasons than anything else - a spilt drink on a pc keyboard is a lot cheaper to remedy than a laptop keyboard <img src=/S/grin.gif border=0 alt=grin width=15 height=15> )

    Thank you all. These answers have answered all of my questions. Would one or more of you now please check out my other question yesterday about whether to eliminate the various dump files when I do my weekly disk cleanup. I haven't previously heard of dump files.

    Re: Computer Sleep (Vista Home Premium)

    I do have one additional question about shutting down however. My experience with XP (not sure with Vista) and with Photoshop, is that after working for a while, the computer would be slower and slower, finally virtually non-functional, and the only thing I could do about it was to do a restart reboot. Somehow that was the only way to "clear out the cobwebs" and get the system, and Photoshop to begin functioning properly. again Restarting seemed to fix something that I couldn't correct any other way. So, with these memory hungry programs such as Photoshop (and now using Vista), is anything accomplished by Shutting Down or by "Restarting" ? What does restart do that Sleep or Hibernate (or just leaving the computer on) doesn't do? Should my practice be different if I've been running Photoshop (my only memory hungry program) vs. the more general MS office and web useage, and various other less complex programs?)?.

    Clears out all those programs that take memory and don't give it back! An unfortunate fact of life, I'm afraid - a regular restart is required when using some programs. You may be able to kill off remaining (sub-)applications using TaskManager, but a restart is generally the cleanest method.
