Wondering about power management with desktop computers
I use Arch on my desktop computer, so there's no need to worry about conserving energy.
But my computer has been much louder since installing Arch; I assume this is because it is running at max, and that is because I have no power management tools installed.
Is running my computer at max speed all the time beneficial to the system? Or should I install something to scale the power on demand?

That is unfortunate.
I disagree with some of the things being pushed by the greens; A lot of what they push are thermodynamically or ecologically wrong when you look at the big picture. But, that said...
We should take reasonable steps to conserve wherever we can. There is no reason for a desktop to scream along at full speed running "Screen savers" that require significant GPU effort. At the least, a desktop should be configured to reduce CPU speed, turn off the displays after a couple minutes of non-use, turn off the eye-candy screen savers and spin down disks after some reasonable amount of time.
Look for peripherals that have low-power modes (especially printers)

WADK components & setting used for power management with answer file for windows 8.1 ent
hello,
I have to deploy windows 8.1 ent device with MDT answer file related to power management with customized following settings:
High performances
sleep timeout settings
standby or sleep and hibernate setting
Enable critical battery task.
But don't know
1. how to manage power settings using answer file (WADK) for win8.1.
2. which OS Windows image component and setting used for power management in WADK.
Thanks
Richa KmThe way I do it with my task sequences (this works with MDT as well as SCCM) is to have an exported power plan using the POWERCFG -EXPORT command. I create a software package around the resulting *.POW file with a command do do an POWERCFG -IMPORT.
I then issue a POWERCFG -SETACTIVE command to the GUID of the *.POW file to enable that power scheme.
More information on the POWERCFG command can be found here:

Registry issue with Lenovo Power Manager with X61
I have the following problem.
Hi guys,
Lenovo power manager v1,6 quit working properly lately so I googled for a solution which involved removing power schemes which had reproduced in the registry to cause an overload to the application.
Anyway because this wasnt really working (I ended up with having powerschemes but wasnt allowed to change them) I in my brightest moments decieded to delete the messed up part of my registry [HKEY_CURREN_USER --> Control panel --> PoweCfg] because it was preventing my reinstalations of said program from functioning properly since they resorted to the previosly present registryentrys.
Well it appears that when installing the powermanager it does not write these new registry entrys and Im stuck now without a way to get them back. I wonder at what point that registry entry is written in the first place, does anyone feel like exporting said part of their healthy registry...please...?..this one is from an x200 with Server2003...seems like you're familiar enough with registry exports and wrapping and shoiuld be able to convert this into a *.reg form:

latest T400, vista 64bit
every time I start the computer, windows tells me, the power manager stop working.
I already update the power manager to the latest version.thanks for being the very first one to reply! that's a very good question you ask, but unfortunately, the answer is no.
to clarify, a power gauge does appear when the computer is on battery, but it is not the thinkvantage power gauge; it is just the one that comes with windows xp. when i pull the power, i see only a blue battery bar in my system tray. the battery gauge i'm talking about is a green battery gauge that sits not in the system tray, but in the task bar (to the left of the system tray).
no windows xp update spoiled the functionality; i know this because i did not update windows xp at all between the time the gauge last showed up and the time it disappeared. what i did do was install a program called "shadowuser". i found it was causing problems, so i uninstalled it, but it seems the damage had been done. after uninstalling it, i uninstalled and reinstalled thinkpad power management driver and thinkpad power manager, but the power gauge never came back. the other possible cause of the problem is that shortly after getting rid of shadowuser, i had to force reboot my computer by holding the power button. this is something i rarely have to do, but i had to do it in this case. i did a bit of searching and found that the power gauge disappears for some users if explorer.exe crashes, so this may be the problem. but if uninstalling and reinstalling won't fix the problem, what will? all my other programs (even those that shadowuser messed up) are working fine after shadowuser was uninstalled, or at least after the programs themselves were uninstalled and reinstalled. right now, i'm deeply regretting not imaging my hard drive while everything was working flawlessly. but must i pay the heavy price of reinstalling windows and all the other programs on my laptop because i mistakenly installed the trial of one program? -

Can't turn off WiFi Power Management with iwconfig
I had an issue with my WiFi connection dropping occasionally, and I found that my situation was the same as described in this part of the Wicd wiki article: <https://wiki.archlinux.org/index.php/Wi … connecting>, so I used iwconfig to turn power management off, like it said. But, the disconnecting issue is still there. I think power management is still on, because of this:
[<...>]$ cat "/sys/devices/pci0000:00/0000:00:1c.1/0000:02:00.0/net/wlan0/power/control"
auto
[<...>]$ cat "/sys/devices/pci0000:00/0000:00:1c.1/0000:02:00.0/net/wlan0/device/power/control"
on
Yet, iwconfig still shows that power management is off:

Should I worry about power management load cycle destruction?
I can't say I know much about this, except that I've heard from multiple people that there's a problem involving HDD load cycles and laptop power management destroying the HDD, specifically on Ubuntu. is this something I should worry about? Thanks.
OK, I did some looking into this problem, and here's what I found...my load cycles were increasing by ~120/hour, and it seemed like that was a result of the APM setting on my hard drive being at 128. So I changed it to 254, and it seems to have stopped.
So I added "hdparm -B 254 /dev/sda" to /etc/rc.local. Will that workaround be sufficient? Will the increase in temperature be a problem?
Am I being specific enough? I'm kind of unsure if what I'm saying makes any sense. -
Power Management with User Account
On my T43p, I have the newest power management version installed and XP SP3. In the power management, I cannot change power profiles from within a user account. I can however change the power profile in the Windows control panel (this only after I changed the power policy registry keys). Is there a way to make power management do this?
Hi,
I have discovered a workaround to this problem, but it's not a definitive solution. When you log in as a 'not administrator' user, you have to use the 'Run As' command of WinXP on the file (right button mouse click on it):
"C:\Program Files\TOSHIBA\Power Management\CePMTray.exe"
And then, you have to insert username and password of an administrator user. You have to do the same thing to the
file:
"C:\Program Files\TOSHIBA\E-KEY\CeEKey.exe"
if you want to use the function key too, to change power profiles.
The problem is that you have to do this each time you log in as limited user. If it was an Unix O.S. you could set a flag SUID in the files to execute them always as administrator. But this is Windows and I don't know if there is a way to do this!
Anyway, there is another possibility. You can use SpeedSwitchXP tool (http://www.diefer.de/speedswitchxp), instead of the toshiba power management tool. This software is a power management tool that works from a limited user too, but you have to give write access at all users to the following reg keys:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Curr entVersion\Controls Folder\PowerCfg\GlobalPowerPolicy
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Curr entVersion\Controls Folder\PowerCfg\PowerPolicies
These keys are necessary in order to modify power schemas. You can give write access to these reg keys with the standard tool 'regedit'. -
Is there any way to override the Toshiba Power Management with the Windows Power Management???
Have an older P25-S607 and would prefer more control over the power management.....that I can get with Windows....any suggestions?
Solved!
Go to Solution.Thanks for the obvious reminder That was a duh moment. It's easy to forget the simple sometimes when you get involved in troubleshooting when it's not something you do on a daily basis that's for sure. The Toshiba controls have been fine for the life of the Toshiba laptops we have had, but I always felt they were a little limited on options IMHO.
In this instance I needed to utilize some of the added XP options as this laptop actually had the hinge 'sprung' a little and didn't "shut down" or hibernate when you closed the lid.....changed hubby's "normal procedure" for utilizing this "shop laptop" so he didn't overheat and fry the hard drive which is what I believe happened originally to the system that had been working fine until the hard drive was fried. Changed it out, reloaded everything for him only to have the system need to be reformatted again within a week as windows took over. As I was investigating causes I realized the malfunction. Not sure of the how or why, but now have automated shut down backups if he forgets to shut down when he shuts the lid and walks away. So far so good -
Power Management with SM30X-102
Hi,
I want to use the Toshiba Power Management Utility with a non admin user account on notebook. If I try, I get the message that I have to be a admin. If I make a selection as a admin, the values are not used for the normal user account. So my notebook only works in full speed if I'm not a admin. Any idea if there is a setting under XP where I can change power management as non admin user ?
thanx

Gnome-power-manager with networkmanager_sleep option
I have a wireless device using the ipw2200 module. I have always found it extremely annoying that gnome-power-manager asks NetworkManager to sleep before suspending, since, first of all, the ipw2200 module doesn't need to be unloaded and, secondly, because I always have to wait the extra few seconds it takes for NM to send the dhcp request after resuming. I made a patch that adds an option to turn the NM-sleep call on or off via a gconf entry (networkmanager_sleep). The patch has been accepted upstream and included in CVS. However, I've made a patch that applies cleanly to gnome-power-manager 2.16.1 as well. Here it is:

It would be great if this could be added to the official package, but I'm not expecting itHave a look in gconf-editor to see if there's a setting for that? (I can't check now, I'm using XFCE.) Also, check that you didn't keep the default "put computer to sleep when the lid is closed", but I suppose you've done it already...

IPhone library Management with 2 Computers
Hi,
So here's my issue. I have a laptop and a desktop and right now my iPhone is synced with my laptop. I have downloaded songs legally from iTunes onto both computers. I can upload to my desktop the songs I download onto my laptop via the "transfer purchases" feature. However, I cannot download to my iPhone the songs on my desktop because you can only sync one library to the iPhone. So my question is how do I get the songs on my desktop onto my iPhone without having to burn a CD to transfer them to my laptop every time? There's gotta be a way to do this as many people must have this same issue. Thanks for your help in advance!Hi alwmed,
well actually you can use your iphone. But your not syncin. what you do is you plug it in. chose not to sync the iphone, and then right click on the iphone in tunes, and chose transfer purchased content. this is great if you have say a computer at work, and a computer at home.
But there is an easer and better way; if your using itunes 9.0.2 sharing is built in. It's called "home sharing," Home sharing allows your computers to share music directly with each other. it can even be set up to automatically transfer new purchases to the other computer.
http://support.apple.com/kb/HT3819 is apple easy step by step guide to setup and use home sharing.
http://www.wikihow.com/Set-up-Home-Sharing-in-iTunes is basically the same thing as the above guide, but it has a video on how to set it up.
it's important to note home sharing only works if both computers are on the same network.
I hope this answer your question. If it dose, please remember to mark this thread as answered by clicking on the green start above your first post.

Power manager for Thinkpad t440 with windows 8.1 pro
hello,
I has just upgraded my Thinkpad t440 from windows 7 to Windows 8.1 pro. But i could not find Power Manager software to install in my laptop. I want this software to manage my battery to ensure that it stop charging when 80% capacity. I think that it is useful for my battery.
Someone could help me where i can get this software. I could not find in lenovo website.
Regards,
Solved!
Go to Solution.Starting with Windows 8, the conventional Power Manager with charging thresholds is no longer officially offered.
Here's a third party tool to set what you need:

You still need to have the requisite power management drivers installed for it to function properly.

OK, So I dont really know anything about Power Management, as ive never really cared.
But now that ive been keeping my system on all the time, id like some help getting Standby (sleep) mode working.
If I understand it, this either uses APM or ACPI, its a desktop system, a year old. Which would it use? When I was recompiling my kernel, I noticed APM was enabled, but not ACPI.
Anyway, When pressing the Power button in Windows, it puts the computer into Standby mode. How would I do set this up in Arch?
Also, when powering down, my computer doesnt actually turn itself off. I tried "apm=power-off" in Lilo, from another thread, but it didn't work (just didn't turn off). Actually, I may not have set it up right.
I already have: append="hdd=ide-scsi" , in LILO, so im not sure if I add the line after "hdd=ide-scsi", thats what I did though.
Any help would be appreciated. If its not possible to have it standby on pressing the power button, I could set it up using the Xscreensaver Daemon. That seems to have an option for automatic standby.sud_crow wrote:
Hi,
just a thought:
# CONFIG_ACPI is not set
CONFIG_APM=y
# CONFIG_APM_IGNORE_USER_SUSPEND is not set

the "is not set" thing, means (at least is what i think) you didnt compiled the kernel with that niether with a module,
right! if you look at .config by hand ... better use
make menuconfig
#or
make xconfig
to configure your kernel, because then you dont have to wonder for funny "is not set" behind out-commented lines

Kernel-docs: ACPI wrote:
CONFIG_ACPI:
ACPI/OSPM support for Linux is currently under development. As such,
this support is preliminary and EXPERIMENTAL. Configuring ACPI
support enables kernel interfaces that allow higher level software
(OSPM) to manipulate ACPI defined hardware and software interfaces,
including the evaluation of ACPI control methods. If unsure, choose
N here. Note, this option will enlarge your kernel by about 120K.
This support requires an ACPI compliant platform (hardware/firmware).
If both ACPI and Advanced Power Management (APM) support are
configured, whichever is loaded first shall be used.
-> it is generally a bad idea to include ACPI and APM both in the kernel, because you then cannot decide whichone is used and which not ...

CONFIG_APM_REAL_MODE_POWER_OFF:
Use real mode APM BIOS calls to switch off the computer. This is
a work-around for a number of buggy BIOSes. Switch this option on if

CONFIG_APM_CPU_IDLE:
Enable calls to APM CPU Idle/CPU Busy inside the kernel's idle loop.
On some machines, this can activate improved power savings, such as
a slowed CPU clock rate, when the machine is idle. These idle calls
are made after the idle loop has run for some length of time (e.g.,
333 mS). On some machines, this will cause a hang at boot time or
whenever the CPU becomes idle. (On machines with more than one CPU,
this option does nothing.)

CONFIG_APM_DISPLAY_BLANK:
Enable console blanking using the APM. Some laptops can use this to
turn off the LCD backlight when the screen blanker of the Linux
virtual console blanks the screen. Note that this is only used by
the virtual console screen blanker, and won't turn off the backlight
when using the X Window system. This also doesn't have anything to
do with your VESA-compliant power-saving monitor. Further, this
option doesn't work for all laptops -- it might not turn off your
backlight at all, or it might print a lot of errors to the console,
especially if you are using gpm.
actually APM should work without --- except you are a special case with a funny bios or something else funny ... then you should consider activating them, but gernerally you dont need them -
Xfce4-power-manager & change icon in Xfce4 panel
Hello!
I'm trying to change the appearance for the latest xfce4-power-manager (v1.4.1-2). I use elementary Xfce icons. The former xfce4-power-manager was using the correct (simple black & white) elementary icon in the notification area in the Xfce4 panel. With the latest version, where xfce4-power-manager has to be added manually to the panel, it is using some kind of colourful icon.
Is there some way to tell the program to use the elementary icons instead? I've already tried to edit /usr/share/applications/xfce4-power-manager-settings.desktop. But no dice.
Thanks in advance.Do you know the location of both, the simple black & white icon and the colourful one?
If you do, you can try the following. Backup the original colourful one and paste a copy of the one you want to use in the same location and with the same name.
Afterwards check if the result is the one you want.
I have myself come across the situation of wanting to change an icon through the .desktop file but in the end it seems that some icons, even in this case maybe?, are hardcoded and can't be changed through a .desktop file.
More than willing for someone to proof me wrong though!
