View 9 Replies View RelatedJudging 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:

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?
View 2 Replies View RelatedWhat 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.
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.
View 1 Replies View RelatedI'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.
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.
View 2 Replies View RelatedI 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.
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.

Is there a way of throttling a process resources, something akin to limits but for processes not users?ie I want processX to be restricted in the amount of memory it can consume. For process cpu I guess I can simply nice the process, but total memory consumption is my primary concern.
View 1 Replies View RelatedI am using Ubuntu 10.04 64-bit and I purchased a new ALFA AWUS036H wireless card. I would like to know if this "1Watt" wireless card is configured for full power. iwlist wlan0 txpower results:
wlan0 unknown transmit-power information. Current Tx-Power=27 dBm (501 mW). It appears to me that I should be able to increase the power. "iwpriv wlan0 highpower 1" does not work. Do I need to patch the new default driver that comes with Ubuntu 10.04 64-bit with the aircrack one following these directions:[URL]...? Monitor mode and a injection tests seem to work fine with the driver I have installed.
The fan noise caused by my HP envy 15 when I'm using OpenSuse 11.3. When the computer is under W7 there is almost no fan noise. In OpenSuse, however, every three or two minutes the fan goes very loud. It sounds as if the machine were doing hard processing work when it is just surfing and doing office stuff.
Another issue is the battery consumption, I already tried the power option but the under OpenSuse the machine eats the battery in almost half of the time than under W7. it stands for just one hour under OpenSuse, when it uses two in W7. These machine comes with a core i7 and an ATI graphic card.
Can you suggest bandwidth monitoring software for GUN/Linux that will log bandwidth based on usage/consumption.
Not options:
- slurm or any other "real time" bandwidth monitoring
- /sbin/ifconfig <interface> | grep "RX bytes" or the like
What do you use to monitor your monthly, daily, hourly bandwidth consumption (assuming that you do).
My monitor tools indicate that the percentage of swap used is more than the ideal , so I want to calculate which process is consuming from the swap. I tried the following but it didn't help be 100%
#ps -eo vsz,rss,pid,args | sort -n
How to accurately calculate which process consuming from swap, just the swap no ram + swap!
My laptop has a very high consumption when running on idle (I mean nothing that write on the disk or video etc..). I read on lenovo forums that people could get 10-12W and I can hardly get lower than 20W. My cpufreq is set to powersave and my cpus are always at the lowest scale.
configure my laptop to save some power. It used to last almost 7h on battery (sadly I don't remember the consumption) on Ubuntu and now it can barely last more than 3h with slackware.
My config is:
T400 intel duo core 3,06ghz
14.1" TFT display with 1440x900 (WXGA+) resolution with LED backlight
Switchable Graphics with Intel GMA 4500MHD and ATI Mobility Radeon HD 3470 (256 MB)
320GB 7200rpm 2.5" SATA HDD
Intel Wifi Link 5300 (AGN)

I have some general question with with quite an impact for the system I use I have a media server with 2 raid1 mirrors of 2 1 To disk aggregated with lvm and used by a big 2 To ext3 partition.A few days ago, munin (awesome!) started to send me notifications about smart attributes of some disks. Fyi, here's my hdparm.conf:
/dev/sda {
spindown_time = 54
}
/dev/sdb {
[code]...
regarding reliability and disk longevity, is it recommended to have them spin down while not used (most of the day, as these are storage unit for movies, pictures, documents..) or let them spin whatever.. ? Those are WD green and according to Tom' Hardware, the consumption is only slightly greater in idle compared to standby. The other question, (boat one as we say in french ) what is the best configuration here ? My 2 raid 1 stripes, or a raid 5 ? I know that two disks kill the raid 5, and they have to be of the same stripe to kill the lvm on the raid1, but what are the odds ?
I use Squeeze with Xfce. My problem is that recently (after the xfce updates) the xfce power manager doesnt react to the power button - it is set to suspend. I dont have gnome-power manager or anything like it running.
If i reboot the computer, the power button will work but if i suspend and resume, it doesnt work again.
The computer is built on an Asus M3N78-VM mobo (2GB RAM/Athlon3200+ single core).
acpi_listen detects the button press.
Any thoughts?
Is there any tool in linux, so that the bandwidth, each user consuming, can be monitored.
View 2 Replies View RelatedI'm looking for any power monitoring devices for Linux to allow monitoring power quality, voltage changes, and outages. This would be for North American three phase power system. I want to have this data fed live to my own program. It should be something much better than just jury-rigging a circuit to fee the power waveform into 2 or 3 audio cards.
View 10 Replies View RelatedOn the last release, I had this app installed where I could pick my power profile. I could use power conservatively, and performance would suffer a bit, but longer batt life,or I could have it automatically detect, or I could have the apps use all the power they want and then some. I'm looking to reinstall that app. What was the name of it?I can't remember, and so far, can't find.

PC is a AMD athlon64 3300+ 2.4ghz SiS graphics
probably the power-supply or what?
If it is the power supply, how do I find new one as I've never had to replace anything on it or any other PC?
Also, I really need access to the hard drive but it's a weird hard drive and was wondering if I could put that hard drive in my K7 PC, which already has 2 drives in it can a pc have 3 drives? do I have to add/have another ribbon cable for 3rd drive?
After much research, I have found the solution to my intermittent wireless problem!Whenever the laptop is plugged into power, wireless is perfect, when I'm on battery, wireless is horrible.Here is the fix:
Code:
sudo iwconfig eth1 power off
Unfortunately, I have to type this in everytime I unplug the laptop.
