Power Saving & Scheduled Shutdown

I work in a computer lab at a grammar school... it's a small room but we have 15 eMacs squeezed in, and they generate a lot of heat. I've tried putting the machines on a schedule to start up at 9 am on weekdays, and shut down at 6:30 pm every day, but invariably, they're asleep at 6:30, and so the shutdown never happens. I set them to never go to sleep, too, but it doesn't seem to stick. We're running 10.3.9 on most of these. This sound familiar to anyone?

Hi,
You can create a scheduled task using group policy preferences to initiate shutdown.

  • Nokia C7 - POWER saving SCHEDULE for night period

    Hello NOKIA!
    I have a suggestion  for  "the biggest (and most awaited!) update ".... PR  2.0  for  C7  &  N8.
    We know that all phones with touch screen are big consumers of power and the battery life greatly decreases.
    I do not use the phone at night.
    It can be very useful to set Power Saving to start automatically at night, for example at 23.00 and was to expire at 7.00 (between 23.00 - 7.00).
    Thanks!
    PS: please Nokia, expected answers even if we do not receive major updates do not understand why we C7 clients, we have to wait nearly nine months for PR 2.0 which is already on  Astound  ... in nine months a child is born ....
    ... it would be nice to meet someone in this topic .... /t5/Cseries/How-can-I-manage-add-a-new-folder-in-my-email-client-Nokia-C7/m-p/941655#M14031

  • Scheduled shutdown and power settings

    I have set up a policy to shut down all domain computers at 1900 every day with Task Scheduler via GPO, but there is still something that I need to configure.
    Working hours of the company that I work for, are from 0800 to 1700, but there are still employees that remain after working hours to finish their daily tasks. Many time it happens that the any computer won't be used at all, but they just do not shut it
    down.
    I would like to set a policy which would apply after 1700 to send the computers to sleep mode after 30 minutes of inactivity and then shut down the computers that have been on sleep mode for more then 15 minutes. So they do not have to wait till 1900 to
    shut down.
    Thanks

  • N8 - Activate power saving mode

    Dear all,
    Usually when I go to sleep I setup my N8 phone to power saving mode, however I have problem to desactivate it.
    My phone have crashed for six hours until shutdown.
    How can I turn off my phone under those conditions? No keys worked.
    my regards,

    If your phone freezes up completely to the extent that no keys work try this:
    Hold the power button down for at least 8 seconds, when it vibrates release the button. The phone should now reboot and behave normally.
    I do not know why it froze up in the first place, many things can cause a phone to freeze or crash. More details would be required from you to troubleshoot that problem.

  • No power saving

    Hi!
    I've just installed Arch 64bit on my Lenovo g560 notebook and I'm experiencing some power saving issues. On windows my notebook can run about 2,5-3 hours with wifi on but under linux it runs less than hour! I installed and configured laptop-mode-tools and cpufreq-utils, daemons are running but it looks like power saving is not working at all.Any ideas?

  • Scheduled shutdowns

    I have my MBP and iMac set up to shutdown every weekday (my GF likes to leave them on!!) but if they are already shutdown they start up just before their scheduled shutdown time and then shut themselves down, is this a common problem with Leopard? I don't see the point in starting up to shut down if it's already shutdown.
    Does anyone know if there's a fix to this (apart from removing the scheduled shutdown)? Does anyone else have the same problem?

    Try trashing the Power Management preferences, restart and reset them to how you like.
    You can find the file here:

  • Scheduled shutdown no longer works in Keynote 4.0 iLife 08

    Those of us using Keynote, a large LED monitor and a Mac Mini as a Digital signage system have found that the new Keynote 4.0 in iLife 08 will not allow a scheduled shutdown. This worked well under the old version.
    We had been on iLife 06 and 10.4.9. We found that Keynote crashes every few days when you try and run a show 24/7 so we had used the energy saver settings to have it shut down at 1AM and restart at 2AM. This was working well, the only trick was to always name the current slide show the same thing and have Keynote auto launch at startup and run the slideshow.
    Last week we reimaged a Mini with 10.4.10 and iLife 08 and put in place of the 10.4.9 ilife 06 mini, the first time it was suppose to shutdown it hung, there was an error on the screen that said "Keynote had canceled shutdown".
    Testing proved the following:
    Schedule shutdown does not work at all when a Keynote presentation is running. You get this error.
    "The application Keynote canceled shutdown. To try again quit Keynote and choose shut down from the Apple menu"
    It will auto shutdown and startup IF a Keynote slide show is NOT running.
    It will do a scheduled shutdown if just the Keynote App is running.
    If the Keynote app is running a normal shutdown command will work.
    Does anyone know a work around or a fix?

    The thread "Keynote Cancelled Shutdown: how do I troubleshoot?" has recently posted a possible solution but is there an explanation or a fix planned?

  • Changing to power-saving results in losing picture on the screeen

    Hi,
    Product name: HP Pavilion dv6-6093ex Entertainment Notebook PC support.
    Product number: LM610EA#A2N
    When changing to power-saving GPU, then Radeon got disabled and no picture on the screeen is shown.
    I really had been facing a problem with my Windows 7 Home premium 64Bit, then I have only done a repair install, which
    didn't delete all the drivers and programs. However, before doing the repair install, I was recommended to uninstall AMD
    Readon and Intel(R) Management Engine Interface.(AS shown below). Thus, I have uninstalled the AMD Readon, and Intel(R)Management Engine Interface.
    Upgrading Windows will affect the following devices and/or programs: 
    These devices might not work properly after the upgrade. Before upgrading, we recommend updating the drivers for these
    devices. Cancel the upgrade, open Control Panel and search for "update device drivers", or go to the device manufacturer's
    website to search for updated drivers.
    System devices: Intel(R) Management Engine Interface
    These programs might not work properly after the upgrade. We recommend uninstalling these programs before upgrading. Cancel the upgrade, open Control Panel, and search for "uninstall a program". (Note: Programs marked as * can be safely reinstalled after the upgrade.)
    ATI Catalyst Control Center *
    When the repair install got completed, then I found that Grphics adapter is still functining well since there are no ! mark in front of the adapters: Intel(R) HD Graphics Family and Radeon(TM) HD 6770M in the device manager.
    Once I changed the GUP from High-performance GPU to Power-saving GPU, then I lost the pircuter on the Screen.
    When I lost the picuter on the screen while on Windows in normal mode, I booted to the safe mode, then opened the device manager, and I saw that Radeon(TM) HD 6770M was disabled
    To get picture again,  I enabled Radeon(TM) HD 6770M (screen shot below) while in Safe mode: 
    When restarting my PC and started Windows in the noraml mode,  the picture returned on the screeen.
    Whenever changing to power-saving GPU, then the same problem happens.
    Will I need to reinstall the AMD High-Definition Graphics Driver, although there are no ! mark in front of the Intel(R) HD Graphics Family and Radeon(TM) HD 6770M  in the device manager?

    Thank you so much indeed,
    Could you please take some of your precious time out to really answer these questions below of mine?
    Firstly:: I really have run this Utility(amdcleanuputility) to remove all components of the prvious installation of AMD Radeon and Mobile Inte Graphics.
    I was propmted that  tool will do as it is shown below in the screen shot.
    I agreed. Then, it completed. Is 'AMD cleanup utility' recommended by you?
    Then, the graphics adapters in the device manager became as follows:
    Secondly: I think that it is now the point to reinstall AMD High-Definition Graphics Driver_Software Packaging Numbr(SP55092)_Driver Version 8.882.2.3000.
    Thirdly: Moreover, I would be saying that I lost the audio on my System once the (amdcleanuputility) has completed, although its icon is still intact(screen shot below)
    Must I need to reinstall IDT High-Definition (HD) Audio Driver_Sp55094_Version6.10.6345.0????
    Finally::  in your link about downloading the drivers for my product name. I found Driver-Graphics (5) . However, all what I need is the finall one which is an already-downloaded file with me. Could you please let me know what about the other four graphics drivers????????

  • Power saving tipps for desktop PCs

    Hi, lately I've been trying to make my boxes at home (router, desktop, fileserver) more power efficient. My energy bill was always kinda high and I think that I waste too much energy.
    Most of my experience with computer related power saving comes from my laptop (maximize batterie time ). I've already taken some steps to minimize power consumption but I'm not sure what else could be done. If you have some ideas please let me know!
    Some details about the steps I've taken so far:
    router (24/7)
    Its an really old stripped down mashine (P2) that is underclocked (hard).
    It's currently running pfsense (FreeBSD based) that is installed on an old hdd. I was thinking about getting a small usb-stick and running the system on that one... would that be a good idea? (lifetime etc)
    fileserver
    Runs only when needed. In addition the cpu is undervolted (ondemand). Should be ok I guess.
    desktop (24/7)
    This one is a bit more tricky. It has pretty much up to date (-> power hungry) hardware but needs to run 24/7 most of the time (ssh, ftp, p2p). Downgrading can only be temporary because sometimes I need the performance (casual gaming, video encoding, photoshop etc...).
    So far I did only 3 things:
    1. hdds go to sleep when they are not used for 15 minutes --> hdparm -S 180
    2. cpu undervolting --> cpufreq-set -g powersave
    3. grafik card underclocking --> nvclock -n 250 -m 350 (nvidia only)
    I'm a bit frightened to underclock the grafik card even lower... my screen got blocky and froze once while testing. ^^'
    2 & 3 are done with a small script that I run when I leave the pc:
    #!/bin/bash
    if [ "$(cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor)" = "performance" ];
    then cpufreq-set -g powersave && nvclock -n 250 -m 350 && xset dpms force off
    else cpufreq-set -g performance && nvclock -r
    fi
    I've a shortcut for the script on my keyboard but some automation would be better if I think about it... triggered by afk time or sth like this.
    If you guys have ideas what else could be tweaked please let me know!

    Raccoon1400 wrote:Using a flash drive instead of a HD may save a bit. It may be significant, it may not, but every little bit would help. Flash drive would take much less power. Maybe several times less.
    You could also check out solid state drives for the desktop. I know very little about them, so it may be a good or bad idea.
    Yeah flash drives uses less power but I wouldn't use them for a desktop pc. The price per GB is far worse compared to normal HDDs and the blocks can only be written around 100000 times... for a system disk this is not really acceptable (caching, temporary files etc). These SDDs are more designed for small (sub)notebooks imo because they have no mechanical parts what makes them more reliable.
    For the router this would not a problem though.
    omgwtfbyobbq wrote:A stick would definitely be cheaper! The HD power draw isn't as low as I thought it was but it's close. The power supply can be a huge draw like I mentioned before. There's a 20W and 40W difference at idle between a earthwatts 380 power supply and a couple generic power supplies I had lying around. I originally though my PIII used way more than my C7-D system, but after swapping power supplies I found out the PIII used less at idle than the C7-D even w/ two sound cards, a network card, and a video card.
    Yeah a quality PSU will probably save allot. Currently the router uses an old generic power supply, so this is really sth i should look into. I have an enermax noisetaker that is not used atm so I'll see what difference it makes compared to the currently used PSU.
    The power consumption of HDDs is really not that low (thx for the link). Around eight watts (Idle) for the tested HDDs. So putting the disks to sleep when they're not used is probably a good idea for the most people that leave the PC running for longer times. My desktop has 5 HDDs, so even when they are not really used they need around 40 watts for nothing. Old HDDs (like the one in my router) will probably need more power.
    I've asked a friend of mine to lent me his digital wattage meter. With this I can make some detailed tests to see what tweaks are really useful to save power.
    I'll post the results when I'm done (probably on the weekend). What I can say now is that the few tweaks I made on my desktop PC (first post) will probably save a bit. The temperature of the CPU and GPU drops around 10-15 °C, the ambient temperature drops allot as well. This pretty heavy considering that the case has a good airflow (2 80er fans in front of the hdds and one 120er fan at the back).

  • Mirroring LG Monitor stuck in Analog Power Saving Mode

    I have a macbook from 2006, and just attained an LG L1900J LCD monitor. When I connect the monitor to my macbook using a DVI to VGA Cable attached to a Mac mini DVI to VGA adapter I get no picture on the monitor and the message "Analog Power Saving Mode" appears before the monitor goes black and then switches into sleep mode.
    I have used the Switch application to try and fix the issue, and I have also adjusted the resolution many times as it appears my Macbook recognizes the monitor but an image just won't appear on its screen. I just ordered a Male to Male DVI cable and mini DVI to DVI adapter to see if a digital connection would work. Does anyone know if this will work or of another solution to my problem? Thanks.

    So I ordered a Mini DVI-DVI Dynex adapter and Male to Male DVI Cable off ebay for very cheap, and to my surprise, this set-up seemed to shake the monitor out of "Analog Power Saving Mode" into "Digital" since its a digital set-up and now I have a fully functioning, mirroring monitor. So I would suggest switching to DVI to correct your issue.

  • LG Monitor stuck in Power Saving Mode

    I just purchased an LG W2252TQ LCD monitor and I am using a mini-dvi to dvi adapter and a DVI cable to connect to the monitor. My macbook detects the monitor, but when I connect it, the monitor enters "Digital Power Saving Mode" and is asleep. No picture whatsoever. - I saw another post who was having similar trouble and he solved it by using a mini-dvi to vga adapter, but I'd prefer to use a digital connection. Any help?

    kiamatthews: I bought the same LG monitor for my daughter's MacBook and I couldn't get it to work. Then I read your post and resigned myself to buying the mini-dvi to VGA adapter. Luckily, I stubbornly tried one more time and after a bit of fiddling I finally succeeded in getting it to work. (My daughter has the same setup as you i.e. LG W2252TQ LCD monitor connnected to a MacBook using the mini-dvi to dvi adapter and a dvi cable connected to the monitor.) I'm a relative newbie to Macs, so I'm not sure I've remembered all the steps, but here goes.
    When I first connected them, the LG showed the background from the MacBook, but nothing else (no icons, no windows, etc). Eventually I brought up system preferences - displays, and some sort of monitor resolution window appeared on the LG, but it was different than what was on the MacBook. The "displays" window on the MacBook did indicate both the MacBook monitor and the LG, which it showed as 2252TQ or something like that. Anyway, I checked a box labelled "Show displays in menu bar", which then put a monitor icon on the menu bar. When I clicked on that, there was a line allowing me to select "mirror" which I did. Immediately, what was on the MacBook display appeared on the LG. After I picked myself up off the floor, I was able to change the resolution for the LG to its maximum setting and after about 2 seconds of blank screens, it reappeared with everything working as it should.
    I hope that the above description is sufficient to get yours to work as well.

  • Nokia N8: Possible Power Saving Mode Bug

    Dear All, 
    For the past week, I've change the way I use my Nokia N8. I decided to set it up in power saving mode during the evening. There is no point for it to be on 3.5G if nobody is using it. Unfortunately, I seem to have hit a problem. At the moment, my N8 is using a pay as you go sim card from O2 and this card is in the phone 24/7. 
    When I activate power saving mode, the phone re-registers with the network and the maximum speed it will have will be EDGE. In the morning, when I take my phone I disable power saving mode and the phone re-registers again with the network. 
    Having said that, on multiple ocassions, my phone showed some worrying symptoms. For example, a few das ago, when I disabled power saving mode, the phone did not show the 3.5G icon and I could not make any phone calls. The coverage was up and down. You might say that, it did not show 3.5G because you had no 3.5G you idiot. That is not true, where I live, there is 3.5G everywhere.
    I was shocked that I could not make any phone calls. After a few reboots and taking SIM card out, I managed to get the phone in working order. 
    Today, the same thing happened. I managed to fix it just a few moments ago. It seems that the power saving mode option has an implementation problem or O2 does not like the way the N8 registers to the network when you enable and disable the said feature.  Has anyone encountered this???

    @m80116, this may well be a solution, but could be problematic if in a weak reception area where only Edge is available ? You could lose data connection completely ! I tend to use Dual mode, and generally don't have an issue, but certainly for anyone living and working in a very strong 3 or 3.5G area it may work very well, wish I had the luxury of being able to use 3G Only 
    If I have helped at all, a click on the White Star is always appreciated :

  • Adobe Reader 2.0 for PocketPC power-saving issue

    Hello,
    I have a Fujitsu-Siemens LOOX720 device and noticed that device battery discharges relatively quickly when I read PDF documents with Adobe Reader (Windows Mobile 2003SE).
    The trouble is that device runs at turbo processor speed all the time the Adobe Reader document is viewed (even when you switch to other applications and put Adobe Reader instance to background).
    I set the processor speed settings of my device to Automatic Mode and the rest of applications work as expected - they do not consume much CPU power when they are idle and the CPU is automatically switched to power saving mode. This does not happen when Adobe Reader is viewing the document and the only solution is to set the CPU settings to Power Saving mode manually. This is very inconvenient because rendering of PDF documents is too slow in power saving mode.
    I hope the description is clear and it will help to fix this problem in future versions of Adobe Reader.
    Thank you!

    >>> battery drain happens only when the device is powered on and there is running instance of Adobe Reader with opened document. <<
    Actually, my experience is continued battery drain when powered OFF and there is running instance of Adobe Reader with opened document.
    One possibility is that when the midnight calendar update occurs, an open instance of reader may keep the unit powered on.
    On windows mobile devices, the power button is a "suspend" button and applications remain open, and while normally inactive, some programs continue to run and make power demands on the ppc.
    >> report to adobe <<
    It's been pretty obvious over the years that Adobe does not care about nor will invest any resources in the ppc reader to address any user issues.

  • E72 "Activate power saving". Consequences????

     I want to know DETAILS what happens when I push ON/OFF button and select "Activate power saving".
    What are the negative effects of this?
    Noise cancellation still works or NOT?
    Does GPS work?
    What else???
    "The Nokia E72 features active noise cancellation and navigation as well as a digital compass."
    The latest USER GUIDE says NOTHING ABOUT THIS! I used Ctrl-F to find "power saving". Basically nothing is said what happens in power saving mode!!!!
    Languages: English, Finnish

    it disables all UI effects (Theme transitions, etc.),
    lowers display brightness to minimum. Brightness option in display settings is disabled.
    switches the processor to a more power efficient mode (performance is noticeably lower)
    instantly turns off connections when they aren't needed (e.g. WLAN connection gets disabled instantly after you open a web page, if you want to open another one then the device connects and then quickly disconnects again). As a result, push mail gets disabled. You will have to manually sync mails as long as power save mode is enabled.
    Noise cancellation still works. GPS still works - in the same way as with the WLAN connection described above

  • Monitor Goes into 'Power Saving Mode' HDMI

    I have an LG monitor (IPS237-BN) which always goes into 'Power Saving Mode' when I connect my MacBook Air to it via a Thunderbolt-HDMI connection.
    Sometimes it actually connects and I can mirror my displays (or count it as another), most of the time it doesn't.  I have used different cables etc.  I cannot install the driver because I do not have a CD drive.
    Any help is appreciated, thanks!
