I've got a problem with my laptop and I finally decided to try to solve it. My computer sometimes (not everytime) freezes. It's just when I'm using battery power. I figured out that this is not connected with some specific action (e.g. some app crash), it can freeze 1 minute after start or 10 minutes, I think it's random. I've checked my /var/log/messages.log file and these are the last messages before freeze (exactly at 9:16:15):

What's wrong with my laptop? Where should I look for errors?
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.
getting back to our laptop, the stability window is ~3.2V. Meaning that when you operate the battery above this the electrolyte is oxidized on the positive electrode and reduced on the negative electrode. Remember that we only want to oxidize and reduce the active materials and don't want to do anything else. All these reactions other than the ones we want are called side reactions and these are really bad for the battery. The nominal voltage of a laptop battery is 3.7 V which means that something bad wants to happen as we use the battery.So long story short, stuff (e.g., passive layers and poor kinetics of reactions) happens and things are not as bad as they seem and you can increase the voltage up to 4.2V without bad things really happening. All chargers for Li-ion cells today cut the battery off when it reaches 4.2V. What you have to realize is that at 4.2V, these side reactions are present in finite amounts and start to chemically kill the battery, but its not that dramatic.
Operating to 4.1V makes things better and extends the life, 4.0 V is even better and so on. So why don't battery manufacturers cut the voltage off at, say, 4 V to get better battery life? Because every time you cut this voltage down you decrease the capacity of the battery and its run time. The 4.2V cutoff is a compromise between good run time and decent (read "not pathetic) life.On the other hand, if you charge the battery and then pull the plug (so to speak), the battery discharges some, the voltage drops, and these reactions become less of a problem and your battery life goes up. So the best things you can do is to charge the laptop (or cell phone, camera etc.) and once its charged, pull the plug. Your battery will thank you for it.As a matter of fact, if you own a Lenovo Thinkpad, you can actually change the state of charge to which you charge the battery using the Battery Maintenance utility. You can change this from charging to 100% state (where the voltage is 4.2V) to 90% so that your voltage is less. You lose some energy is doing that, but atleast you can change it to 100% when you need battery power and put it back down to 90% when you can plug in. I wish my Mac has the same feature.
I typically use the battery for a while (say 1/2 hour to 1 hour), then plug it in and wait to fully charge it, then I pull the plug and use it again for 1/2 hour to 1h and then I repeat this. Takes some getting used to and I forget to do this, but I try.
Fresh new installation of squeeze on an MSI Wind U100 netbook.Everything works fine, except resuming from hibernate when on battery power. The netbook starts loading the hibernate info after grub booting, then the screen goes blank and the netbook reboots.The unusual thing is that resuming from hibernate works when on AC power.Could not find anything interesting in /var/log/messages
I'm using debian testing on my Asus UX305. When my laptop is connected to power, the power notification still shows "discharging". And The battery part of the laptop feels unusually hot.
while connected to power, "acpi -b" gives me this information: Battery 0: Discharging, 98%, discharging at zero rate - will never fully discharge.
This problem was reported by some ubuntu users too: [URL] ....
Is there any way to allow normal fsck boot-time checks when running on battery power? After looking around, the only solution I've seen is to manually alter the /etc/init.d/checkfs.sh and /etc/init.d/checkroot.sh files and remove the AC power check. There must be a better way than that surely?
When I am working with Windows OS on the DELL-Vostro-1014 laptop the battery is working. If however I switch to Debian Squeeze OS the battery does not work. Running #hardinfo & shows that there is no battery. Am I right in assuming that the driver for the battery?
/sys/class/power_supply/BAT0 gives model_name DELL X612G0 Serial No. 18069 manufacturer LG
What driver is needed, where to search for it and how to incorporate in the kernel 2.26.32-5-686 ?
Just installed 9.10 followed by a 10.04 upgrade (wouldn't work as a 10.04 clean install). The install and upgrade all seemed to go well.
But now when booting I get a message saying "checking battery state" and then it boots no further. This is a laptop without a battery installed, running permanently from the mains through the charger.
How can I disable this check so that the laptop will still boot without a battery fitted?
I managed to install Jessie on my new Lenovo Ideapad 100 and have been trying to put the finishing touches on it. I downloaded FDPowermonitor and the icon showed up right away. Then after a few minutes it went away and hasn't shown back up.
I think I need to modify /etc/xdg/lxsession/LXDE/autostart to include @fdpowermon but I cannot figure out how to have the permission and use a editor I understand.
I just log into LXDE with root... but there has got to be a better way yes? But that didn't work anyway...
I have looked all over the place but I can't find if this is possible. I am running Debian 6 as a media server (SMB) and it is tied to a UPS, I used gnome power management to set up a low battery shutdown but this UPS also is powering another embedded computer. So, I was wondering if it was possible to have a script run (to log in and shut down the embedded system) before gnome power management shuts down the Debian server. I know I could probably get it to run on every shutdown, but I am looking for low power only.
After a successful install of the MFC-J4420DW printer and scanner using Brother's install utility, I am experience severe battery drain and xsane freezes (total system lockup, requiring using CONFIG_MAGIC_SYSRQ keyboard command REISUB or hard reset).
The Brother support page and utility/drivers are found here: URl....My laptop is the HP Elitebook 8540W and I am running Debian 8 using LVM, separate partitions for /home, /var, /temp, /swap, and /. I have looked at logs in /var/log. kern.log, daemon.log, messages and dmesg, but have not found any relevant info ...
I purged all drivers/packages and tried a manual install using each deb package, but ran into some permission errors, so I purged again. I also purged xsane and reinstalled it, then did a complete printer reinstall using the brother Driver Install Tool.The tool works great, full functionality for the MFC-J4420DW. But I know I can't live with the power drain, and I would really prefer to use Gimp and the xsane plugin rather than simple scan ..
I got a brandnew Acer Travelmate Timeline X (13"). I do not really know if this is the right topic for my problem. But here it comes: The Acer uses a special smart battery with special chips in it controling the powermanagement of the battery and the system. In general there is a kernel module to handle this (sbs). But for me this does not work.I am using Squeeze and it does not recognize the battery. It always acts like being on AC power. If I unplugg the AC it runs with the battery till it is empty. But the ACPI can not recognize the battery and can not read how much lifetime it has. I tried the reassambling method. But this method does not work for me. Nevertheless I think the reassambling method does not run because there is no more developing on it because of the kernel modul.
What can I do? Will I have to wait till a new workaround of sbs comes out, which can handle my battery? I read about a BIOS hack that disables the smart battery functions. Should I try this? But I am not really firm in that kind of stuff and I will loose the guarantee. Has anyone got an idea?
since I am on a Dell inspiron 1545 laptop, being able to display my battery charge is critical. After some extensive googling, I found I need a command 'acpi', which does not exist on my computer. I cannot seem to find it in the packages database; the closest thing being 'acpi-support' apt-get install also can't find it.
I tried cat /proc/acpi/battery/BAT0/state, but that only shows me if the battery is discharging or charging and doesn't give me an actual percentage.
I have a strange problem with the ACPI in my laptop, the problem start some days ago, I don't remember exactly the day.
The first symptom is with de Gnome Power Manager, only show me when I disconnect de AC power, but when connect it again the Power Manager icon disappear and the energy battery stay in the same value.
After search for a while, all the post I read talking about the /proc/acpi/battery directory, but this directory not exist on my laptop.
I have a laptop Lenovo G460. My OS is Squeeze. My Kernel is 2.6.38-bpo.2-amd64, because the 2.6.32 version of the kernel don't recognize well my audio card.
I can't attach the dmesg and the lsmod output because I receive a message "Sorry, the board attachment quota has been reached.", both file are compressed.
First issue is, now that I am running Debian "Squeeze", my laptop runs much hotter than before. Its definitely hot on the very bottom compared to when running Windows. Once the system begins to heat up, the fans start spinning faster, the system gets louder, etc.
Second issue is battery life. I am able to get 5 hours out of the laptop in Windows, but maybe 2.5 hours in Debian. I am assuming that these two problems go hand in hand. Now from experience with PC hardware, I know that the newer chips scale their frequency and voltage depending on demand. I don't think the computer is doing this correctly when running Linux.
By running cat /proc/acpi/processor/CPU0/throttling
I see that the CPU(s) are in T0 state (or 100%). Manually setting the frequency doesn't change anything either (via the gnome applet). Am I diagnosing this correctly?
I have installed Ubuntu (both 10.10 and 11.04 pre-release) on my laptop but my battery is not recognized and it is detected as a desktop system rather than a laptop. I have tried the cat /proc/acpi/battery/BAT1/state method but the directory doesn't exist. I have tried another guide to paste the battery info into this directory but it doesn't allow me to do that and says that the directory doesn't exist, even though I'm trying to make it. I tried it in root nautilus and even on an install of Lubuntu (with a root file manager) but it still failed to budge. I really don't know what to do as I have tried all the guides on the internet that I could find.
Just made a strange discovery, visiting the website: [URL] .... with iceweasel within university's network makes my computer almost unusable. htop's output indicates:
I just installed Debian 6.0 IA64 on my HP zx6000 and it pegs the CPU's when doing absolutely nothing but sitting at the desktop. I searched around on Google and found that there is a bug report: 537572. I was just wondering what the status was on that. Is there currently a fix or workaround?
I use jessie-32bit of kernel 4.1.3 on ASUS EeeBook X205TA. But it doesn't recognize buttery status.Result of my investigation, the incomprehensible ponts is below.
・"acpi -b" outputs no information. ・There is not "battery" directory in /proc/acpi/. (button only exists.)
The following is my system informations. Code: Select allacpi -V Adapter 0: on-line Cooling 0: intel_powerclamp no state information available Cooling 1: Processor 0 of 10

I want to check battery in console and fluxbox Desktop.
I'm currently running my own postfix server which is the MX for my domain. This is hosted in my house at the moment on the end of an ADSL line with a static IP. However, I'm trying to go totally mobile so I can kill the ADSL and the line rental and switch to 3G. Does anyone know a solution which allows me to accept (or ask for delivery) of SMTP when temporarily connected and queues it externally? Sort of like a hosted mail queue which pumps SMTP onto my laptop only when I ask it to.

I am using Fedora 12. Prior to this I was using Ubuntu 9.10. In Fedora 12, I am facing a problem with battery power. Sometimes when it is fully charged I remove the power cord, battery power comes down to 40%-41%. It never happened with Ubuntu, which gave quite a good battery performance. My question is when it is showing Laptop Battery 100% i.e. fully charged, if I remove the cord why it comes down to 40%-41% (and always in this range).
I am running a cli only based laptop for a special project; however, is there any terminal based simple text or GUI applications that will give me power remaining and other information about the battery? Looking for: power remaining, total power, WATTS, AMPS, etc.just the basic items and some other items, nothing to fancy.
I have a starling netbook, but I have the regular ubuntu interface on it. I normally have it plugged into a power source, but now it is unplugged. As I remember, at one time there was an icon on the top bar that showed you how much battery life you have left, but now I don't see it. How do I get info on the percent of power I have left?
I know how to set and have set my net-book gz5 running on lucid to stay on at all times.however unlike in xubuntu I don't have the option to change when the computer is critically low. I don't have the room to install xubuntu with my preferred gnome desktop wondered if anyone out thee knows where if there is a .config file that I can dictate the percentage of battery life before being considered critically low. ei now it seems to consider itself low at 15% which robs me of about 2 hours of usage id like to set it around 1%
