HOWTO Workaround Power Consumption Problem w/ Garm...

Preface
After suffering from low standby battery life for quire a while (less than 24h on E51) I have figured out that the problem comes from a background service installed by Garmin Mobile XT. I have made a few measurements w/ Nokia Energy Profiler and the difference between having Garmin installed or not is 3 fold. That is 0.05W average standby power consumption w/o Garmin installed and 0.16W average standby power consumption w/ Garmin installed, everything else the same.
The Problem
Garmin Mobile XT installs a small service w/ unknown to me purpose which sucks the extra .10W of power even w/o Garmin started. There is an option to Enable/Disable this service in Garmin Mobile XT's configuration menu which is Disabled by default. The problem is that even that the default setting is Disabled, the service still runs once Garmin is installed.
The Workaround
Until Garmin fixes this bug you can disable the background service by following these steps: 
0. Install Garmin Mobile XT on your handset if you haven't done so.  
1. Start Garmin Mobile XT.
2. Select "Tools" from the three buttons on the right.
3. Select "Settings".
4. Select "System".
5. Scroll down and set "Launch background service" to "Enabled".
6. Exit Garmin Mobile XT.
7. Repeat steps 1 - 5 but this time set "Launch background service" to "Disabled".
8. Reboot your handset.
Done
Result
Now the background service will be *truly* disabled and your standby battery life should return to normal.

Thanks for your suggestions, but i was finally able to figure it out myself. linux-lts was unfortunately no option for me, as i want to use bumblebee. But the direction, this pointed me to was good. It seems one of the kernel updates broke my bumblebee package, so the power management didnt work and the card was constantly powered on. This was nothing new, but my powertop completely messed it up, by adding this additional power consumption to eth0. Funny enough, this power consumption even disappeared, when i unloaded eth0. After deleting powertops saved results and recalibrating it, it now shows up all components power usage correctly.
Thus i mark this thread as SOLVED.

  • N660 TF 2GD5 - PerfCap/GPU load/Power consumption problem

    Hello,
    at first, sorry for my english, I will try to do my best.
    I have problem with my GPU when I play Battlefield 4. Problem occours with newest Nvidia drivers, also with beta and older drivers.
    Problem is that I have huge FPS drops periodically, coming maybe every 5 minutes for 15-20 seconds, for example in BF4 it means FPS drops from 50fps to 15fps, really annoying.
    It does not matter at scene complexity, it´s the same in huge battles as when I am alone looking up to the sky.
    I was searching why is this happening and GPU-Z helped me to indentify PrefCap, and immediately GPU load + Power consumption going down from 100% to 40-50%
    I have a screenshot, but can´t findout how connect attachment (external links are not allowed).
    Could somebody explain me what is the problem and why is this happening? I am thinking about to sell my MSI graphics card and buy another one because of this, I don´t want any throtling problems because of compatibility or whatever   
    Is there any way how to turn it off or disable? Register, something.
    Thank you

    you seems to be right guys.
    I undervoltaged my CPU by -0.1V, lovered Frequency to 3600MHz and problem is gone.
    So, time for new PSU 

  • MSI KT3 Ultra-ARU power supply problem

    Hello !
    I am a lucky owner of MSI KT3 Ultra-ARU motherboard but have one problem. My power supply Fortron (FSP Group) 300-GT 300W seems to have some kind of incompatibility with this motherboard. In my case, the computer can't be shutted down by software. With BIOS version 2.5 it was impossible to shut it down with button too. With 2.6 it is possible to turn the computer off by button but software shutdown still don't work. PSU is working on ALL other boards I have tested so far normally. Somewhere in discussions (not in this forums) I discovered that also some kind of weird sounds occurs with Fortron supply on this board and that it is incompatible. Have anyone some clues to solve this PSU problem ? I am not able momentally to buy some other kind of PSU because Fortron is the only brand from higher category to obtain, so I would be like to solve this.....
    Thanks for any info !

    PSU is powering Athlon XP 1700+ processor, the other big power consumer is GeForce4 Ti 4200 GPU. I am not able read currents for specific voltage outputs, so I am not able to measure whole power consumption. Computer is working normally, it is NOT overclocked (but it is stable overclocked too) and the only problem is PSU shutdown by software (win & linux, both of them has this problem). From BIOS v2.6 it is possible to shutdown the computer by power button. If it is tried by software, computer resets itself and three beeps occurs.

  • 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.

  • Nokia N86 power consumption

    I have a Nokia N86 which is 2 years old.
    I have been experiencing a problem with battery drainage since I bought it. The battery meter suddenly drops from 5 bars to one bar when I browse the net using HSDPA, after about 30mins or so, when the phone is already hot. I sent it into service once, because it happened very randomly and it did not look like a major issue. They said they recalibrated the battery. After a week of somehow uniform battery draining, the battery started going flat suddenly, again, from 5-6 bars to "low battery".
    I went to a service center again to check if it's the battery or the phone. Nokia Energy Profiler says that the current is about 400-500mA when using HSDPA. The engineer at the service center connected a power supply with measurable current consumption, and during the usage of HSDPA, the current was at least 800mA, with almost 1000mA peaks. He said that these current intensities damage the battery in about a month and that he would not recommend changing the battery, but the HSDPA chip. The warranty period expired a month ago.
    I am asking you guys:are these values normal? 800-1000mA during HSDPA usage for a Nokia N86? I need a serious, valid opinion from somebody who really knows mobile hardware. Thank you.

    This has happened to me every now and then. First it seems as if the battery is almost full and then it's suddenly empty even without using the device much.
    Sometimes the device feels warm. In those cases I just reboot it.
    Obvious things to check would be that BlueTooth and WLAN are off if you don't need them.
    Sometimes the switch of the kickstand has activated when I have carelessly thrown the phone on a bed for example. If you have defined it to start an application that could cause some power consumption.
    I haven't tried to measure my power consumption. I guess there are two options:
    - the device actually consumes a lot of power sometimes
    - the battery indicator isn't always up-to-date i.e. it shows several bars when the battery is actually almost empty.
    It's a shame because it's a pretty nice phone and I quite like it. Luckily it's quite a rare problem. 
    (But not that great if the battery dies during a bicycle trip just because I have SportsTracker running.)

  • 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

  • What is the power consumption of airport extreme

    I have bought a time capsule which is fits close to my TV and HIFI but I realized it gets really hot, would I have a similar problem with Airport Extreme or is power consomption lower ?

    The TC has a maximum power consumption of 34 watts; the AEBSn uses around 22 watts. Both will run "hot" as they employ large heat sinks just under the top surface to dissapate heat. It is important to allow for enough area around either base station to allow for an adequate exchange of heat from the device to the surrounding air.

  • Power consumption when PowerOFF: 24" iMac 2009

    I really wonder about my iMac 2009 Modell: when using sleep mode I got 11-12 watts power consumption. But when shutting down the iMac (Power Off in Apple Menu), the same iMac takes 10 watts
    Is this normal and how can I get sleep mode with far less or none watts?

    I'm having the same thing with my 2008 24 inch iMac. I'm not sure if it is the hard drive or one of the fans, but there is a loud WHOOSH every time it starts up or wakes from sleep and the whirring noise is pretty much constant. It used to be completely silent, so this new sound is very noticeable.
    Lately, the noise with abruptly stop and then make a struggling sound as if whatever is causing it is either going away or making it stop revolving or whatever (it would help if I could determine exactly WHAT is making the noise). I check iStat, but can't see any wide variance in the fans rpm speeds when it is happening or the heat of various components spiking. It is not affecting my computer use as it did the first time I had a similar problem (which turned out to the the hard drive, since replaced under warranty).
    I bought Apple Care for this computer, so it is still covered under that, but I don't know if the fact that the noise is completely annoying to listen to all day is enough reason to bring it in for service and be covered under the extended warranty.

  • [Solved] High power consumption of eth0

    Hi everyone,
    i successfully installed Arch on my new Acer Travelmate P653-MG a few months ago with the Gnome DE. Everything worked fine until a few weeks ago, when i discovered a really hard power regression due to my network interface. Before i had a solid 12 W of power consumption (without that much of finetuning), but afterwards my power consumption jumped to 23-25 W. I have attached two screenshots of my current powertop output:
    http://i.imgur.com/8tpSnXf.png
    http://i.imgur.com/CaVg61A.png
    Unfortunately i can't quite say when this regression occured, so as to point to a certain update. My first guess was, this had to be kernel specific, but the downgrade from kernel 3.7 to 3.6 brought no results. I must admit after hours of searching google, the arch wiki and the forum here, i'm at a complete loss. I have discovered no one with a similar problem.
    If anyone can help me in this matter, your help would be very much appreciated!
    My current kernel parameters are: quiet splash nmi_watchdog=0 acpi_osi=linux acpi_backlight=vendor
    Please tell me any outputs i can provide which could be of help to you.

  • [SOLVED] Huge power consumption after kernel upgrade.

    Dear All,
    I have recently bought the new lenovo thinkpad X1 equipped with a Core I5 processors and 4GB of RAM.
    I am quite satisfied with this machine except for the fact that the fan is extremely loud (but perhaps a bios upgrade will fix problem).
    Now my problem:
    When I first installed Arch (first days of August) I ran powertop and the power consumption was around 10 Watts when idle with wifi card turned off.
    Now, after some upgrades, the power consumption raises to 18W in idle and consequently the battery lasts less than 2h.
    Here my current configuration:
    Linux think-x1 3.0-ARCH #1 SMP PREEMPT Tue Aug 30 08:53:25 CEST 2011 x86_64 Intel(R) Core(TM) i5-2520M CPU @ 2.50GHz GenuineIntel GNU/Linux

    I have also tried to disable most of the running daemons and unload some modules, but I have never got less than 14/15W when idle, which in my opinion is definitely too much!
    As far as I'm concerned, the kworker process is responsible most of the wakeups. 
    Any ideas?

    enabling it by default in 3.0 caused regressions for some people, so it was
    disabled. Hopefully Intel figures it out, and we can switch it back on by
    default in 3.1 / 2.6.41 (until then, you'll have to set it by hand).

  • I915 power consumption issue after switch to systemd?

    After switching to systemd I noticed a massive increase of power consumption on my Thinkpad X220 (i5 Sandy Bridge).
    The strange thing is, that after some reboots it randomly seems to catch the i915 power saving mode and the consumption gets from ~24W to ~7W at idle. But only after several reboots.
    Adding the good old i915.i915_enable_rc6=1 to the boot parameters doesn't make any differences. But looking at the powertop detail outputs it seems to be a i915 issue.
    Using the latest linux kernel from core (3.6.4) and latest intel drivers (2.20.12).

    I started to get suspicious because I have only ever had the issue in my office. Last week, when I encrypted my drive, my machine wrote to disk for more than 14 hours solid. I then did all the set up and all the restoring from backup etc. with no issue whatsoever. Lenovo ran the thing for 48 hours straight with no problem. But once in my office...
    So I asked the local IT people if they could think of anything other than overheating and explained the issue. They took my laptop yesterday , booted it from a hardware testing CD and ran it for a couple of hours sitting on top of a hot computer in the server room which is definitely hot. (It has a whole bunch of computers, I guess.) No issue. They then ran stress tests for a while in the same place. No problem. Highest recorded temp: 65C.
    The head of IT then took my power adapter to a more general IT service to be tested and inspected. They looked at it, they opened the plug to check the fuse, they tested it. No problem. Of course, the guy also explained why he was asking and the other IT person said, "Oh, is that on level 1?" "Yes..." So apparently there was another machine (a Mac), I think, doing just the same thing in an office in my part of the building. Testing showed that the power spikes and when the power spikes, the laptop shut down as a safety measure. Solution: they installed a UPS for that one laptop. They didn't tell anybody else, including the local IT people.
    What the local IT people were going to do was to install equipment to monitor the power in my office and see if anything weird was causing my laptop to react. However, that was when this was an extremely-unlikely-but-we-are-getting-desperate-for-theories scenario. Clearly, that theory no longer seems wildly implausible at all. So the current hypothesis is that it is most likely that my machine is also reacting to the spikes in power by shutting itself off. (I'm not sure why it should have just started doing this but who knows what the state of the electricals is and how that might vary?)
    I have been told that a surge protector will do no good. (They've given me one anyway but apparently it will not deal with spikes in phase 3 power or something - I didn't understand this bit but the head IT person said he didn't understand it either but the electricals IT person showed him with graphs on the whiteboard. So it must be true.)
    The current plan is to try to get the UPS from central IT which was provided for the other laptop since that person's discipline has since moved to another floor of the building so the UPS probably went back to central IT. They are going to ask during a meeting tomorrow about this possibility. Otherwise, they are planning to order a UPS for me on Monday.
    I'm somewhat surprised that the abrupt shutdowns haven't screwed my data. I've lost work but not seen fs corruption. I didn't take my laptop today. I'll need it next week but I do not plan to plug it in in my office until I have a UPS.
    I'm pretty annoyed, to be honest. I've wasted hours on this and got incredibly stressed about it. The IT people have also wasted a (smaller) amount of time. I hoped to have a new draft of an article I'm working on written by the end of reading week but that didn't happen due to all of this. And they *knew*. It would be different if this was an unknown problem just discovered - of course, one could understand that. But there's a known problem which can cause this type of problem and presumably could well damage equipment without these sorts of safety shutdown features and they don't tell anybody.
    And, no, I doubt very much indeed that a damaged personal machine would be considered the institution's liability. (Maybe if it was a student's machine and the student was required to use it or something but even then...)
    I can't believe it does much good to their equipment either.
    The local IT people did know there was an issue with some burnt out devices but that was about eight years ago and only got mentioned as a outside possibility when other diagnostics turned up no result.
    What gets me is that the proposed solution will only solve the issue for me - not for anybody else in my part of the building on level 1.

  • How to measure power consumption of a brushless DC motor

    Hi,
        I need to measure the power consumption of a moog 23-23 motor using a PXI platform because I need to save the instant power consumption data. I have a Dqmx 6259 and a FPGA module. The problem is that I don't know if I should measure the current and voltaje of all three coils of the motors or if it is enuogh measuring just one, plus is it better to measure in differential mode all the signals directly with the DAQmx or shoul I use a differential amplifier first?

    I don't see anything wrong with your approach; however, I'll throw out a few thoughts:
    If you could tie the sending of the change-voltage command (in your DLL) to the START TASK command for DAQ, you could reduce the variability in the time between the two events. Maybe that's important, maybe not.
    Can you set the voltage via some LabVIEW code, rather than a DLL?
    You might or might not want a variable sampling rate - if you expect 10 mSec, you might want to sample at 10 kHz to catch the 1% difference between 10.2 and 10.3 mSec. But if you're expecting 500 mSec, you could sample at 200 Hz to catch the 1% difference between 500 mSec and 505 mSec, thereby saving data space and processing time. Maybe that's important, maybe not.

  • 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?

    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.

  • Mac Mini - Late '09 - Power Consumption

    Hey guys, this is my first post here Seems like a great forum.
    I got my first Mac the other week, and I'm really enjoying it.
    As I like to try and conserve electricity, I was wondering, if I were to put my Mac Mini to sleep at night rather than shutting it down and starting it up the next day, would I save electricity leaving it sleeping? Like, would it use more power to boot up than to be in sleep for 10-12 hours? Any input would be appreciated
    Thanks, D.

    Based on those numbers, If you will not use the mini for longer than say 12 hours, you will probably save electricity by shutting down.
    But then again, there are other variables associated with the lifespan of components with many power cycling ups and downs.
    Probably not a problem either way or the other, but if you are trying to save money, you already made a good choice with picking the mini- this thing is pretty good with sleep power consumption.
