General :: Unable To Model The Power Consumption Of Various Components
Aug 3, 2011
I am working on a traffic surveillance project which performs various image processing tasks with a number of visual sensors and a computing platform. My basic task in the project is the power optimization/management. I am using a ZOTAC-IONITX computing platform (Intel ATOM CPU + NVIDIA ION GPU). The problems that I am currently facing are:
I am unable to model the power consumption of various components e.g., processor, GPU, hard drive, memory etc, since there seems to be no way to measure the power consumption of individual system components. Since I don't have a power consumption model, I cannot come up with a power optimization algorithm. I am currently working on Linux. Is there any way to measure/model the power consumption of individual system component?
I have already checked powertop. It doesn't tells the power (watts) consumed by a component (e.g., microprocessor). It just gives information about the power state the processor is in (However there is no way to change the power state by the user) and the processors that cause processor to wakeup.

my SheevaPlug just died, and I need to look for new device to replace it. My goal is to build a fanless, low power consumption, linux server. Currently I am thinking of purchasing a QNAP NAS device (TS-110 model) and installing Debian on it.

So I've come across several tips to optimize battery life on Linux. [URLs]. In addition to undervolting, I would like to underclock. Is there a way to control CPU speed outside of the BIOS via some software control in Linux... or some sort of boot manager? I would like to boot to linux using underclocked speeds and have Windows running full blast. Is there a way to run Linux completely in RAM? I have read that saves on power consumption from the hard drive.

According to Phoronix [URL]... aspm&num=1 (which seems to only test Ubuntu kernels) the problems should affect all users of the affected kernels, including Debian's, but that article provides a fix. I don't remember anyone here mentioning lower battery life and increased heat on their mobile platforms, though.

I'm very curious about something. I like to use my command line as much as possible. So, most of my work and usage of my computer revolves around the command line. In such a case I could work without having to use any graphical interfaces. My only current limitation is WLAN connection isn't working for me, but that belongs in another thread and something for me to do for now.
My question is, Is it worth it in terms of battery life to work in level 3 when running a laptop on a batter? What sort of extension to the life would one expect?

I have installed a new PC system
- OpenSuSE 11.3, 64bit
- AMD Phenomen II X4
- ASUS M4A88TD-V Evo/USB3
- 3 hard disks
- etc.
After start-up with runlevel 3, no applications running, network is up, the overall power consumption of the PC (without monitor) is ca. 70 Watt. After some minutes the monitor goes to power saving (terminal mode, runlevel 3 !), but the power consumption rises to 120 Watt! After pressing a key on the keyboard (e.g. Num) the monitor leaves the power save mode, shows the login screen, and the power consumption falls to 70 Watt. In parallel I have investigated the system via ssh and running top, but I have not observed any abnormal operation. I looked into /proc/acpi/* but I did not find something unusual.

Judging by the number of responses (close to zero) to other threads about powertop on this forum, I have little hope in getting any answers. However, I do not know where else could I ask. PowerTop tell me that even after applying almost all the tips and tricks from lesswatts.org, my laptop still consumes over 72 Watts while idling.
Code:
< Detailed C-state information is not P-states (frequencies)
1.60 Ghz 0.0%
800 Mhz 100.0%
Wakeups-from-idle per second : 451.1 interval: 10.0s
Power usage (5 minute ACPI estimate) : 72.5 W (0.3 hours left)
Top causes for wakeups:
[Code]...
Suggestion: Enable USB autosuspend by pressing the U key or adding usbcore.autosuspend=1 to the kernel command line in the grub config This is when I am not touching the laptop. When I am surfing the web or listen to music, it goes up to 2000+ wakeups! How do I cut it further? I am getting like 20-30 minutes max on battery and this is unacceptable cause in Windows I get at least 3 times that.

I'm using Ubuntu 10.04 LTS on my HP ProBook 4510s.[URL]... On Windows XP, the battery usually lasts me over 4 hours but on Ubuntu it barely last 2 hours. How can I reduce power consumption and prolong battery life while running Ubuntu on my laptop?

What my situation was before the problems:
-I dualboot win(xp) and xubuntu(11.04)
-No problems whatsoever except for the fact that power consumption was higher on xubuntu.
Then i read something that said that the kernel i was using was effectively having power issues and that it could be fixed so in went into the terminal and nano'd the grub config file and update-grub'd with the addition i had read all over the internet. When i rebooted it seemingly had worked but once i opened a ..... video it didn't react to anything (i'm 99% sure kernel panic since there was no hdd movement). So i forced it to shutdown and when i got back in again i nano'd the file again but for some reason i didn't only remove the power stuff but I also removed the quiet splash. Once i had rebooted it would suddenly ask for username and password twice.
once the older looking menu an then the newer looking one with the fancy bg). The first time i got in okay but afterwards i could only get in as root. I thought i had simply forgotten my password but i ran passwd myusername as root and it didn't work(only when i typed something random it gave the wrong password message). As root i also can't edit the users and groups(when i open it it stays grayed out). how do i fix this. If i will lose my account anyways then how do i get my files/bookmarks/... of of it.

I just got a question from a customer(actually from a customer to my manager then to me) and he is asking the following question: What are the components that were installed with RHEL? It may sound like a silly question but to me it sounds vague. The main thing I am thinking about now is during install you can select three components: webserver software development and virtualisation.

I want to build a desktop computer. I will be running Linux Mint on it, probably the LXDE community edition. I use it for school (homework and studying), research on the net (general browsing and specific research on Linux stuff since I hope to one day open my own Linux computer store), and for listening to music and watching videos, things like that. I am not a power user, adn I don't plan to be one any time soon. But I am learning how to work in GNU/Linux, since I want to make a living that way.
Currently, though, I just need a good computer made out of new components, that will work correctly. So What kinds of components to get. I need a motherboard, a CPU (I prefer AMD), a hard drive (I will run SATA), and RAM. I have a DVD burner on my current computer, and I can use that in my new system. I plan to put my new computer together in the tower my current computer is using. I am just looking for some knowledgeable suggestions here for what to get to run my computer the best.

I installed the minimal-command line system from the kubuntu CD on my laptop, which is guess is roughly around 200mb after installation. I wish to install a Desktop Environment preferably KDE and I wanted to know how and where do I begin from? Do I need to have a working XORG prior to installation of KDE and do I also need to install Window mangers and e.t.c? What all packages/libraries and components do I need to install first? I'm really not sure where should I begin from.
Initially what I am trying to do is to have working GUI system,then later on I can install rest of the packages and software that I need, like office, GPU drivers, browser etc. Secondly,for a minimal KDE system,what metapackages are to be installed from this site? I believe kdebase, kdebase-runtime, kdebase-workspace are required. [URL]

Which hardware components tend to cause compatibility issues? And how do you select a generic option that might work with your hardware?
I don't currently have any problems but curious to find out if there is a sequence of steps.

My computer was on when the power went out. I am not able to boot into ubuntu 11.4 install since that happened. I also have debian 6 and ubuntu 11.10 installed on the same machine and both boot just fine.
The machine boots as normal but stops with the line "disconnected from Plymouth". After the machine just sits there with a blinking cursor. I cannot start another terminal. Is my only option to reinstall.

I want to disable display power management.
I tried to achieve this by disabling 'Enable display power management' checkbox in the 'Configure Desktop -> Display -> Power Control' KDE configuration dialog. That didn`t help and display still goes into standby mode after some period of inactivity. Also, I tried to disable dpms functionality by calling 'xset -dpms'. That didn`t help too. Note that 'xset dpms force standby'
