Fedora Hardware :: How Does Battery Power Meter Works?
Mar 26, 2010
How does the Battery Power Meter works.As I know that the APCI is control by software.so my question is the battery connected also to other place on the board and send signal for how much power left.or every motherboard that have APCI "Enabled" can recognize only from the DC power connector how much left. if yes, in what why it recognized.
I've been tooling around with Fedora with the Fluxbox environment on my old Dell 400SD4 laptop and it works fantastic. I'm still getting a feel for the environment, but one major concern that I had was a battery meter. Being a laptop, it's important to know when I'm almost out of juice. Does anyone have any suggestions for a battery meter for Fluxbox? Preferably one that can be installed through the yum repositories?
I have an Asus EEE PC900. Just installed 10.04 netbook remix and everything works fine straight out of the box. it works great and is a vast improvement on windows xp which was previously installed on the asus. Just one small thing - the battery meter is never accurate as far as time remaining goes - it currently says i have 19 hours 55 minutes to go - unfortunately this is not quite true i suspect. It was the same with 9.10, Does anyone have a solution for this?
I recently had to turn ACPI off because of major errors like the child_rip error, but now I don't have battery support or anything like that. No battery meter, etc. Is there a way I can get this while ACPI is off?
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).
based distros but never tried it in others. I am wondering if I can complete this guide in Fedora 15. In order for Linux to be my primary OS (Which I'd really like it to be) I need to be able to see how much battery power I have. If all the packages are available how I can download them and what not so that I can get my battery power back up.
I have gnome-screensaver on fedora 10 on an intel mac (laptop) under power, screensaver works fine. On battery, the screensaver never activates, it will eventually go to sleep though. I'm kind of new to fedora.
I just upgraded to f15 x86_64. I use a VPCCEB3Z1E vaio laptop and I noticed that my laptop can't last more than half past an hour running from battery in wireless productivity (just surfing the net and make some word processing, so nothing so heavy...) I use kde 4, installed cpupowerutils (replacement for cpufrequtils), put the modules acpi_cpufreq, cpufreq-ondemand -powersave and the other governors in /etc/rc.d/rc.local for loading them at boot. Edited profiles in powerdevil (every profile has cpupowerutils freq-set -g and the name of a governor) but i still notice no changes. How I can get a better power management on this laptop? Fan still runs at high speed.
I recently installed Ubuntu 10.10 Desktop Edition on my HP Compaq Presario V3018TU Note Book PC.It is working fine. The problem is with Power Meter.It shows battery Charged in Icon, though it is discharging. Also after clicking on it, it should show % battery power. But it only shows (estimating).Is there any way to fix this ?It was working fine with Ubuntu 10.04.
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%
I have no Wifi on Battery Power?My wifi quits when power cord is pulled? I plug in the power cord and wifi works again?Dell XPS 16 1645 Ubuntu 10.10Much appreciated for a link to solve the problem or instructions
I'm running 11.04 on my Dell SXPS 1645. Today I unplugged my laptop from AC power a few times and after about 10 minutes, Ubuntu would hang, not responding to anything. Frozen mouse, frozen keys. The ONLY thing I could do to get it out was to do a hard hardware restart by holding down the power button.
It happened twice on Skype (and I thought it was just the buggy 2.2 beta that was hanging my beautiful OS), once while installing a printer, and once while I was just futzin around on firefox.
Since my upgrade from Lucid my battery icon displays permanent full charge even when running without AC power. When the battery runs out, this leads to an immediate violent shut down, everything dies at once.
My power management settings for running on battery are as follows;
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?
I'm running the latest slackware64-current on my Dell laptop (Inspiron 1420). I rarely run it on battery power, so I don't know when this behavior started, but now it seems when I'm on battery power the hard drive likes to spin down and then spin up. This is not after 5 minutes or so of inactivity. This is 30 seconds of inactivity because I'm reading a web page or something. There is a noticable delay in the response of the system as a whole when the drive is having to spin back up. I'm also using xfce-4.6.2 with the xfce power manager. I've checked the settings, and I don't see anything about spinning down the hard drives. I've also looked through some ACPI rules, but I'm coming up empty.
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 recently bought a 12-cell (extended-life) battery for my HP dv8000 AMD Turion64 laptop. While the extra battery life is spectacular, the machine is virtually unusable when not plugged in. Either the hardware or the OS (I'm not sure which) seems to view each of the 12 cells as a separate battery, so whenever a cell nears depletion and the machine prepares to transition to the next cell, the computer slows to a standstill, as though it were shifting into an extreme version of Powersave mode. This can last for several minutes at a time, during which period all I can do is stare helplessly at my screen.
I have all but disabled Powersave features in the Power Management applet, setting the laptop to Performance mode on both AC and battery power, with Powersave only kicking in below 10%. So that isn't the source of the problem. I have also disabled Compositing and all desktop effects, except the mouse pointer application-icon animations that appear when I open an application, which I can't figure out how to disable. All this to no avail.
Plug the machine back in and it zips along at a merry Linux pace. I don't want to keep it plugged in all the time, though, because a) this is a laptop and therefore should be mobile; and b) keeping a charged battery plugged in drastically shortens its battery life. Besides, this is a brand-new battery; it should still be working fine.
I am having several problems with what i believe to be gnome-power-management. Power management will randomly say that either i do, or don't have a battery. This means that the icon in the notification area does not appear, and I can not access the settings for on battery power. also, when i tell Ubuntu to suspend, it just goes to the screensaver and nothing happens. conky is still able to read the battery just fine, its power management thats having problems.
For example if my netbook runs on AC i would like it to start emesene, Skype etc. on system startup, but if it runs on Battery i want different startup programs - less of the same programs basically -.Is there some script i could use for this purpose?
Under "Power Management Preferences" > "On Battery Power" > "When battery power is critically low" : We have several options : Suspend, Hibernate, Shutdown; but we don't have the do nothing option.Does any one know if i can disable all these actions so the computer will do nothing when the battery power is critically low? May be by a terminal command?
I'm having a huge performance decrease when I'm on Battery Power. Plugged in this thing runs AMAZING, HDMI with HD video, I can run compiz 3d, full desktop advanced effects, HD video from ....., you name it. Just when I pull the cable out it slows down. I tried disabling ATI powerplay but that didnt help.
Is there a way I can toggle the performance, so that I can get "plugged in level performance" even when i'm on battery power? I'm not too bothered about how long the battery lasts. I'm usually always near an outlet.
I have an Acer aspire notebook.graded from lucid and now I have a really big problem:every time i disconnect the ac-adapter from the pc, the system freeze completely, became unresponsive to commands and to sysrq. i need to phisically turn off the machine and then back on.
I have a Dell 1501 Inspiron laptop and have swapped out the broadcom network card for an intel 4965AGN so I can use n-speed with my new router.Everything works sweet except my laptop now crashes if I try to run on battery power.It boots up to the login screen, but once I enter password and login it crashes, just get grey screen and everything locks up. Everything works fine on mains ?It's not a major problem for me as I don't use the laptop "out in the wild".
just installed Ubuntu on my Macbook Pro and im loving it right now, but whenever I disconnect from the power source and run from battery, my wifi Internet slows down to a crawl. As soon as i plug the power back in, the internet is back to normal.
I've got a Toshiba Satellite with the Realtek rtl8188ce network card. I've successfully downloaded, compiled and installed the driver and it works great except when running the machine on battery power when it constantly disconnects, like every minute or two.
My problem is that my sony vaio E-series (VPCEA36FA intel i5-560 4gb ram). The battery should stay at least 4 or 5 hours as i checked in windows platform but on ubuntu 10.10 it stayed only 3 hours now on 11.04 it stays only 2 hours !!! which really pisses me off, so is there any things i should know?? also the fan sometimes get so high i feel that the processor works on highest performance although am not using it that much.
