Ubuntu :: Reduce Power Consumption On HP ProBook 4510s?
Feb 8, 2011I'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 RelatedUbuntu :: Going Green - PowerTop And Cutting On Power Consumption?
Feb 27, 2010Judging 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.
Ubuntu :: Get Files/bookmarks/ - Higher Power Consumption
Jul 5, 2011What 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.
Debian Configuration :: Increased Power Consumption On Kernels >= 2.6.38?
Jun 29, 2011According 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.

Mar 21, 2010I'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?
OpenSUSE Install :: Power Consumption With Blank Screen?
Jan 7, 2011I 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.

View 2 Replies View RelatedGeneral :: Unable To Model The Power Consumption Of Various Components
Aug 3, 2011I 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.
General :: Optimizing Laptop Battery Life (Saving Power Consumption)
Apr 20, 2010So 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.
View 4 Replies View RelatedUbuntu :: Reduce Desktop Window Size Within Screen?
Aug 23, 2010Can the size of the Ubuntu desktop window be reduced so that it displays on a monitor or via a data projector with a surrounding black border? If so, how? The tragicomic chain of events which leads to the question is as follows. Community group, short of cash, want to equip lecture room. Pull-down screen is set up permanently on one wall. Contractor sets up old data projector via ceiling mount. Data projector is just too far away from wall, such that image cannot be reduced sufficiently by the data projector to fit on the screen.
Annoyingly the image, as displayed, is only slightly too large - just enough to lose the top and bottom panels, Applications menu, File Menu on full-size windows, Indicator applet, Trash, and restore desktop button. The data projector is hooked up via VGA cable to a recycled PC running Ubuntu 10.04 with proprietary NVidia driver (version 173) for GeForce 8400 GS. I'll give anything to be able to do this on the PC, rather than having to move the projector!

View 4 Replies View RelatedServer :: Reduce RAID5 Partition Sizes / Reduce The Size Of Md1 And Grow Md0?
Feb 14, 2010I have a rack of four 1TB drives all partitioned identically with three primary partitions. On each drive
- the first partition is only 64MB;
- the second is a large 900GB partition and
- the last holds all the remaining space
mdadm has been used to set up
/dev/md0 - RAID1, comprised of /dev/sda1 and /dev/sdb1
/dev/md1 - RAID5, comprised of /dev/sda2, /dev/sdb2, /dev/sdc2, /dev/sdd2
/dev/md2 - RAID5, comprised of /dev/sda3, /dev/sdb3, /dev/sdc3, /dev/sdd3
OK, so it was a silly mistake to make - but I am now need to increase the size of /dev/md0. My thinking is to reduce the size of md1 so that I can grow md0.
On md1 I have two logical volumes. I've successfully reduced the size of the volume so that I can reduce the size of md1. Now I'm at the nervous stage; I can find little written on the topic of shrinking RAID5 arrays - and even if I do this I'm unsure if I can move partitions around to regain the space I so desire.

Jan 29, 2011I was up all night trying to set up for a switch from Linux Mint 10 32-bit to Ubuntu 10.10 64-bit. For the most part, the migration has been successful. However, I'm having an issue with the power management settings: even though I've told Power Management to never turn off or lock the display, it does so anyway. I've saved it as default, rebooted, and still the same - after several minutes, the screen turns off and shows the lock screen when I wake it up with the mouse.

CentOS 5 :: Ver5 On Desktop (DEll OptiPlex), Power Cut Oops!?
Sep 10, 2011I no expert and this was a bit of mucking around. Installed Version 5 dot something on a desktop (DELL OptiPLex) with a couple of extra HDDs, for a server to play with (samba to Windows). I used the drives as a single logical drive via LVM.
We had a power cut, now it doesn't work. In fact it's been hanging around for a couple of years and before I dump it I wonder if there is any chance of getting some of the wife's letters, pictures, etc that I promised I try and get off.
The /boot partition seems to be there and I've attached a photo of what happens at boot, and I admit....I haven't a clue what it all means. Also I did not think ahead and did not create a recovery disk. I know, I know heap damnation on me for being so reckless, but any chance I can get myself back in the wife's good books?

OpenSUSE Hardware :: Fan Noise And Battery Consumption On HP Envy 15 - 11.3
Sep 5, 2010The 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.
