Power consumption double compared to windows... where could energy be

I just bought a new Laptop (Acer Aspire 5755g), and first thing after I got it was, of course, installing arch ;-)
However, I noticed that the energy consumption under Linux is at least about 22 Watts in idle mode, while it uses only 10 Watts on the preinstalled Windows 7. I was wondering where the big power leak could be. That's what I already thought of:
• I enabled most of the laptop-mode energy saving options, that means ondemand CPU governor, soundcard/ethernet/wireless powersavings, usb autosuspend, hard drive power saving etc...
• Since it is a nvidia optimus laptop, it has two graphics cards. However, I disabled the nvidia graphics card in the BIOS (what saved about 5 Watts), and I think the remaining "cheap" intel chip should not use that much power.
• The laptop has an LCD LED display that can be quite bright. However, the 22 Watts are measured when background light is almost at the minimum.
Are there any ideas, where else the problem could be?
I know of the kernel power regression discussed on phoronix recently, but can this really double the power consumption?

What made the laptop finally turn of the fans, and really saves a lot of power...
Indeed, this and the pcie_aspm option, plus disabling the NVidia card with power management from Bumblebee (extra dangerous BTW, I would not recomend, though I use it) and unloading some modules, took my Alienware M11xR3 consumption down to 7.95W.

Idle power consumption in arch twice as high as Windows 7?

I have some issues with power consumption in Linux.
Here's the rough setup:
i5 750, stock settings
Asus P7P55D-E premium
HD5770
LSI-3081-E
8 WD20EADS
2 X-25M G2
Enermax Modu 87+
The whole system as listed above idles in Windows 7 at 59.7W with all but one SSD spun down and at 122.8W in archlinux, also with everything but the root SSD sleeping.
I've also disconnected the power of all drives and the result was roughly the same.
I've already installed cpufreq-utils, acpi-cpufreq is loaded on startup and the governor is ondemand (50% threshold). cpufreq-utils indicates that the processor idles at 1.20 Ghz as it should be.
Catalyst 10.4 is also installed and should take care of the HD5770, I've verified that atieventsd (which is supposed to be responsible for the power management) is running even though it isn't in my rc.conf, probably because it gets loaded with the fglrx module.
Any ideas what could possibly cause the idle power consumption to be twice as high in arch?

You could install powertop though, to verify if the p and c states get used correctly.
Yes it is likely but you should verify to be sure.
I would if i could. You probably want to address clesch instead of me .

Before I upgraded my iPad mini, you could turn off apps to save battery power by double clicking the control button and then holding your finger on the app button until the minus sign appeared. That doesn't work anymore. How do you turn off the apps wit

Now you swipe downward, the app will appear and you delete, keep scolling to the right as in the past. With the new operating system you also swipe downward to get the search bar to find an app

I installed Windows 7 in my Macbook pro, I can access Windows data in Mac, but I can't copy and delete it. and the same case while i am working in Windows. Could you please guide me if there is any solution, where I could copy/paste/delete my data.

OS X can natively read NTFS of Windows, but not write to it.
Windows can't read or write to HFS+ of OSX, and that's a good thing from a security standpoint.
Ideally if you share files between operating systems you should have a FAT/MSDOS formated USB key or hard drive. (exFAT external drive if any of your files are over 4GB in size) both these formats are universal for OS X or Windows.
If you install software into Windows and OS X to read each others formats, then you have to pay to update/upgrade it deal with headaches.
If you swtich between Windows and OS X a lot, don't need full hardware performance for Windows, you may consider installing virtual machine software like VMFusion or Parallels which can take a copy of your Windows in Bootcamp and place it into OS X as a file then run that copy of Windows in a window in OS X like so.
Advantage here is you run most of your light weight Windows programs like this at the same time as OS X.
Benefit is you can run just about any Windows or Linux version and OSX server editions (not client versions)
Bootcamp only allows Windows 7, that's it now.
You'll also be interested in two fre pieces of software, Carbon Copy Cloner and Winclone on macupdate.com.
CCC clones OS X partition and Winclone clones the Bootcamp partition. Valuable for you.
Good Luck

Where are power options saved in the Windows registry?

The problem is that a customer IT department did something wrong during deploying GP preferences. Now nothing is working and we have to delete all settings, that the new GP preferences I newly created will work.
Now GP preferences is not working on 300 clients. I don't know what they have done. If we reinstall the clients, GP preferences (power settings) are working fine. They have only used GP preferences for power settings. No other changes before the problem started.
My senior manager told me to delete power options / settings in the Windows registry. So I can delete this?
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\explorer\ControlPanel\NameSpace\{025A5937-A6BE-4686-A844-36FE4BEC8B6D}

Hi
Where are power options / settings from Windows 7 saved in the Windows registry? We deploy the energy settings via GPO’s.
Many thanks in advance

Where can one get power consumption figures for PCI-E Cards?

as i wrote before im putting together a fairly decent rig, and im doing some heavy duty research into the actual total power requirement for it, using PSUCalc2003.v2 spreadsheet to calculate the total, however ive been unable to get the power consumption figures for my nvidia based graphics accelerator a Gigabyte Tech GV-NX62TC256DS with turbo cache, my guess is that this card is at the lower end of the power consumption spectrum but it would be nice to know the exact figure,
any ideas on where can i get those figures ?
thanks.....

If you buy the 5770 from Apple as an upgrade kit it has the cable(s) - two for the 5870, one for 5770.
If you bought a mac pro mid-2010 it may very well have come with cable(s), that I have never read or heard from others.
OWC has not always inicluded cables but has charged extra, as they did with eVGA GTX285 where Apple sold with cables, and buying from OWC added another $30? or more to the cost with cables "extra" is what I recall.

Power consumption when running window XP

Hi guys!
Hmm, recently i've asked a question on the other forums regarding the power consumption of my macbook pro while running window XP.
I realised that when i run window Xp, the battery life can only last around 2 hours, while when I run mac OS X, the battery life is around 4 hours.
However, I've got a reply at the forum and the reply cause me to be worried...
Here's the reply...
Power management is built into Mac OS X. So OS X constantly monitors the power consumption and energy profiles of the system while in use.
Windows XP and Vista, on the other hand, is built off the NT kernel which was NEVER meant for mobile computing. Unlike OS X, Windows XP and Vista does not have built in powe rmanagement: it actually relies on the low level BIOS (which is almost 3 decades old as of today) to manage its power consumption and settings.
Since the Macs do not boot using BIOS but rather, with EFI, to boot Windows, the EFI creates a BIOS emulation layer to support Windows. because this layer is emulated and the user has no control over it, Windows loses ALL forms of power management: the fans on the Mac will run at max, EIST will be disabled, wireless receptivity and hard disks will be set to consume all the energy they can grab, among many other things. Especially for hardware with moving parts like the fan and the hard disk: prepapre for premature hardware failure if left running at max performance all the time.
So can I ask, is this true?
Will running window XP on macbook pro causes the hardware to be spoilt more easily?
I have another friend who runs window XP on macbook and he told me that the hardware will not be affected by it, so can I reassure myself on that?
Thanks a lot. ^^

Yes, Win XP is a battery hog. I have an issue with Win XP not dimming the display the way OS X does before going to sleep. Running Win XP should not harm your hardware, it just drains the battery faster. I am looking into ways of improving batter life with Win XP. For now just make sure that you have the power settings in Win XP set to laptop/portable. If you need instructions on adjusting those settings I can provide them.

Actual power consumption on WS-C6509-E

Hello everyone,
I have a WS-C6509-E with two WS-CAC-6000W power supplies. I have to determine what is the real power consumption of the whole device but I noticed that there is a mismatch between measurements and show power output so I would very much appreciate if someone could explain why is that so.
I did the following test to try figure out the consumption from the power grid.
Step 1. When both supplies are active, show power gives me the following output:

Step 4. I used the current clamp to measure the current on the remaining power input and it reads 4.9 A.
When I multiply the current with voltage I get
P=4.9*230=1127 W.
So why does the show power output gives system power used = 2253.72 Watts, which is actually double value of measured 1127 W? What am I missing?
Thank you in advance for any help on this,
Marin

marin_otto.
Where are you located and what AC line voltage are you operating on (208 or 230v)? I ran into your post and was wondering if you were operating on 208v which is line to line (two hots) and perhaps you are only measuring current on one line, effectively half the power.

Tecra R840 - Win8 - power consumption in hibernate mode

Hello,
i did the offered upgrade to W8, i am very satisfied with the W8 system, but the problem is that the notebook is consuming battery also in the hibernate mode.
I would understand that the power consumption will be in the sleep mode, but on the hibernate mode?
I found out that when the computer enters the sleep mode or hibernate mode and i open the lid, the computer automatically starts EVEN if the option to "power up computer when lid open" is unchecked.
When i select to power off computer - it does not react to open lid, i have to press the power button.
The problem could be in the windows system, that the OS tolds the computer to wake up when the lid closed.
The problem is, that the computer starts charging everytime i wake up from hibernation (i had my office 15minutes from home, and it consumes about 1-2% from battery.
It is quite anoying that my full charge battery capacity is on 83% of original one (i bought my PC in June2012).
I had Lenovo T60 7yrs ago, and there was an option to start charging the battery only when the battery charge was under 95% and it saves the battery capacity.
Does anybody have some clue?
Thank you!

Fact is that battery capacity will be reduced even if the notebook is completely OFF. Battery capacity will lose few percent of capacity. To reduce this check - http://aps2.toshiba-tro.de/kb0/FAQ9C015N0001R01.htm
Useful document for you can be also http://aps2.toshiba-tro.de/kb0/HTD9401AZ0001R01.htm
> I had Lenovo T60 7yrs ago, and there was an option to start charging the battery only when the battery charge was under 95% and it saves the battery capacity.
As far as I know such option is not available on Toshiba notebooks. When connected to AC power supply notebook starts to load battery automatically.
There is no option to change anything.

W520 nvidia quadro power consumption

Dear community, I have a short question about power consumption. I did a clean install of windows 7 64bit on my W520 with a quadro 2000. Power consumption when idle with max brightness is somewhere at 18 watt, definitely highter than what I had with the Lenovo default installation. Checking Lenovo's energy software indicates that the GPU is running at full speed all the time so I thought this could be a source of additional power consumption. I installed the latest Lenovo graphics driver from the homepage, but I'm not sure if thats enough. Maybe there is a problem with Nvidias Optimus technology or the switchable graphics? I'd be glad about any feedback and, yes, I know that I'm a little bit on my own with a clean install. :-) Thanks, Branagh

I get these numbers from the basic view. The battery tab does not indicate power consumption when I have the power chord connected. If I'm on battery the wattage numbers match.
But the result remains the same no matter if I'm on battery or plugged, or what power settings I use (setting the display to max brightness and the machine idling): If I force the laptop to be on the Nvidia graphics, power consumption is at arond 18W, if I allow it to use the intel graphics, it goes up to at least 20W. GPU load in the power manager is always given at 100%.
GPU-Z gives more adequate numbers I guess. When I force the Nvidia GPU, the load is correctly displayed at 0% when idle and the core clock goes down to 50Mhz. When I use the intel graphics the load remains at 1% and the core/ram clocks remain at 650 / 533 Mhz all the time.

ALC889 power consumption

Hello,
i'm running a little media server on clarkdale basis (MSI H55M-ED55, Intel i3-530) with sound chip ALC889.
Kernel is 2.6.32.9-1-ARCH and architecture is x86 Archlinux.
The hardware is supported nicely so far however there's one thing i'm not very happy about.
When playing music the power consumption climbs from 20 Watts (idle) to 28 Watts although the workload of the CPU is only 1%.
Enabling power_save for the chip alone saves 2 Watts when idling.
Compared to the consumption of the audio chip in Windows 7 which is 1 W at most the 8 Watts are unusually high for a sound chip. Is that a known issue or do you know if it can be resolved somehow? I've tried kernel 2.6.33 but the high sound consumption remains.
I assume it's just a kernel driver thing which i can't do anything about but I'd be glad to hear different.
Regards,
demian

You can measure your G5's power usage with this device

Power Consumption Revisited

I was reading an article on tomshardware.com the other day in which they described a process by which they were able to measure the power consumption of various video cards using a simple device that plugs into a standard wall socket and then displays the number of watts the currently plugged in device is using. In light of the ever-increasing PSU recommendations that tend to show up here (I recall seeing one poster recommend "a PSU with 24 or more amps on the +12V rail for anything other than a barebones system"), I decided that it might be beneficial to these forums if I did a little empirical study of my own. So anyways, I shelled out ~$30 for the device shown here:
http://www.supermediastore.com/kilwateldet1.html
...and ran some tests of my own. The results:
Preliminary Testing -
To verify that my power meter would give reasonably accurate readings, I first hooked it up to a 3-way lamp with a 50/100/150 watt bulb installed. The readings returned for the 50/100/150 watt settings (respectively) were 44/94/142, so it would seem like my power meter is at least reasonably accurate. Some other stuff I measured just for the hell of it...my speakers use 3 watts of power in stadby mode, and 30 watts when active (haven't yet tested when active and playing at full volume), and my monitor uses about 70 watts when on, and about 2 watts in standby mode.
Results -
Satisfied that I had not just wasted my money on an inaccurate power meter, I then went and hooked it up to my PC (the one described in my sig) and measured the power consumption under a variety of circumstances. It is important to note that these readings reflect the total amount of power drain being applied to the wall socket, not the amount of power that is actually being demanded by the system. This is because no PSU is 100% efficient (a good one will be maybe 80% efficient, if even that much), so the amount of power that is actually needed by the system is actually about (at least)20% *less* than the recorded values. Anyways:
During startup, the power usage spikes very briefly at 197 watts, then averages 152 watts over the rest of the boot cycle.
The system uses 134 watts of power when idling.
Under full CPU load, the system uses 168 watts.
Running 3d Mark 2001 the power usage is 169 watts.
Playing Far Cry (high detail settings, 1024x768x32), the power usage is again 169 watts.
Conclusions -
So, let's now assume a worst-case scenario, in which the extra 34 watts recorded during full CPU load came entirely from extra CPU power drain (a reasonable assumption), and in which the extra 35 watts recorded during 3d Mark and Far Cry came entirely from extra video card load (a much less reasonable assumption), and in which we have a PSU that is 90% efficient (greater efficiency means that the system would actually have to demand *more* power in order to get the total power drain up that high). In this case we see that if an application were developed that fully taxed the video card and CPU continuously, the total power drain would be 134 + 34 + 35 = 203 watts (which actually correlates rather nicely with the 197 watt spike observed during the boot cycle), meaning that the system is demanding about 183 watts from our unrealistically efficient PSU (note that with the PSU efficiency set to a more realistic 75%, the system would only be demanding a mere 153 watts of juice at full CPU and video card load).
Admittedly, the video card in my system is relatively weak, so let us again take the worst case scenario and assume that if I were to be using a 6800 Ultra, the total power drain would be 100 watts greater (this is above what the actual difference should be given the results posted on tomshardware.com regarding the power use of the 6800 Ultra), so our video card now consumes an astounding 135 watts of power, and our total power drain (in our unrealistic situation where we have some application which is capable of 100% CPU and video card utilization for a sustained length of time) is now 303 watts. With our unrealistic 90% efficient PSU, it would mean that the system is demanding about 273 watts from the PSU (about 228 watts with a 75% efficient PSU).
Note that aside from the weak video card, I have a fairly robust system (which also happens to be slightly overclocked), with 4 HDD's (two of which are WD Raptors), 2 optical drives, several PCI devices, and two large 120mm case fans, and yet the power demands of this system, even in an unrealisticly demanding situation, are *well* within the ability of a quality 380W (or even 300W) PSU to deliver. In this case even if all the power happened to be being sucked off of the +12V rail (which is not the case), any PSU with 18 amps at +12V could still handle it. Furthermore, even if I were to add a needlessly power-hungry video card into the mix, the power demands are *still* safely within what any decent 380W PSU should be capable of (and even what a quality 300W PSU should be capable of, although this may be pushing it a little, though it should always be noted that the numbers indicate a hypothetical worst-case power drain that should be beyond the maximum drain possible in any real-world situation).
So, we can therefore conclude that the power demands of a reasonably robust Athlon64 based system are not astronomical by any means, and that they do not justify a minimum recommendation of a 465W PSU with 24+ amps on the +12V rail for any system which is not "barebones," and that there is no observational evidence to support the idea that a PSU with 18 or fewer amps at +12V is categorically inadequate for use in an Athlon64 based system.
...anyways, I guess that's all, I hope you found this interesting, or at least informative. I'm off to see what else I can do with my power meter thingy...

Really? Do you have measured data which clearly supports your claims, or are you just holding up an opinion as a matter of fact?
My point was, my measured results show that the total power demand of an Athlon64 based system across *all* of the rails is fairly low, even at 100% system load. So, let's recalculate things assuming a 75% efficient PSU, with 75% of all load being at + 12V (which is still probably higher than the actual value), and let's leave the hypothetical 6800U inside of my system. We get .75 * 303 = 227 watts in total that the system is demanding. Of these 227 watts, the system is demanding .75 * 227 = 170 watts over the +12V rail. 170 watts / 12V gives us a total demand of 14.2 amps on the +12V rail. Note that this is with the hypothetically demanding 6800U card installed and is still likely to be at least a couple amps higher than what a *real* system would ever use, and any *quality* PSU capable of 18 amps at +12V should still be perfectly adequate for use in the system.
Furthermore, PSU efficiency dropping to 60% in real world situations supports my results, as it means that the actual system was demanding substantially *less* power than the system in my hypothetical example, making things even *easier* for the PSU. Re-running the above equation with a 60% efficient PSU and 75% of all power demand coming from the +12V rail, we see that the system is only asking for 11.4 amps at +12V at full load with a 6800U installed (and also at full load).
If you want to disagree with my results, that's fine, but don't expect me to take your argument as credible unless you have some actual, measurable data to back up your claims. Saying "this is the way things *really* work because I say so" doesn't cut it, so until you want to break out a multimeter and measure the amps your PSU delivers to the MB on the +12V rail at boot, idle, load, and gaming and then report your results and discuss whether or not they are consistent with your "amps are what counts" hypothesis, I hold my results and conclusions up as being valid, and as soon as I see any measured results which contradict mine, I will gladly stfu about PSU recommendations being needlessly high.

Extending Power Consumption by Day report to more than 31 days

Hi
I need to provide some information to management about computer activity on different days of the week in our environment. My first thought was the Power Management reports in SCCM and the 'Power Consumption by Day' report seems to fit what I'm after pretty
well. The only problem is that the report only covers a 31 day period and I need to increase this.
I found this line: set @reportStartDate = DATEADD(Day, -31, @reportEndDate ) in DataSet one for this report and assumed I could just increase the number from -31. However, when I attempt to edit this, or indeed edit any part of this report,
when I try to save it I get an error:
'More than one report item in the report has the name 'image1'. Report item names must be unique within a report.'
As I mentioned, this error appears if I try to edit and save any change within this report whereas I can do the same on other Power Mangement reports no problem. So it looks like an issue with this particular canned report.
Does anyone have any idea how I can get round this? As far as I'm aware the report files are not available in a directory on the server but are stored in the database so I wouldn't know how to go about looking for this duplicate 'image1'.
If there is an alternative solution that doesn't involve using this report I'm open to anything.
Thanks in advance

Actually the power management reports are stored on the site server. They can be found under <Install director>\Reports\Power Management within the cab file. You can exact them and edit them.. I recommend that you made a copy of
the report and don’t over write the existing report.

Great, I'll try looking there.
Thanks Garth

Power Consumption for iMac 20" INTEL DUO CORE

I need to know which is the power consumption for the 20" 2.16 GHz INTEL CORE DUO. I want to buy a UPS for this machine and I could not figure out in any place within the manual where to get that information. It is something that have to be very easy to find but it was not the case for me in this opportunity.
I cannot believe that I have to create a post in order to get this answer!
Kind regards to all and thanks for any clue that any one can give me.
iMAC 2.16 Dual CORE 20" Mac OS X (10.4.8)

Welcome to the discussions!
Another vote for APC. I use the XS900 for my first gen G5 iMac and it works very nicely without their PowerChute software. It even comes with the correct USB cable to hook it into your Mac.

Power consumption double compared to windows... where could energy be
