CentOS 5 :: Laptop Automatic Shutdown On Low Battery Not Working
Aug 28, 2010
I'm trying to make my system automatically shutdown once the battery level is low, but still without success. I've tried kpowersave, gnome-power-manager, kpower, klaptop but none of these worked for me. Well, I can't imagine I would be that stupid, but simply it doesn't work. In all cases mentioned above (kpower, klaptop, gnome-power-manager) I've tried to setup the laptop to shutdown once the defined level is reached, but the laptop never actually switched off unless all the battery was drained.
Btw. I think all the above mentioned apps only work once the user is logged in. But I'd like the solution to work also when the PC is on without anyone logged in. I thought I could write a bash script based on parsing of acpitools output and define it as a service, which would monitor the battery level, but I simply don't believe there isn't any functional solution to this.

I'm trying to make the power manager NOT automatically shutdown / sleep / hibernate when battery power of my laptop reaches critical
I am surprised there isnt an 'NO ACTION' option for that in power manager
I've tried editing the acpi-supper in /etc/default bu couldn't find a solution in there nor in the /home/user/.gconf/apps/gnome-power-manager/ directory

I am using a Fujitsu Amilo pi3560 with a Realtek rtl8172 wireless card, and running the latest driver (rtl8192se_linux_2.6.0014.0115.2010). The OS is Ubuntu 9.10.
Everything runs perfectly - when my laptop is connected with the power cord. But when I go battery the wireless disconnects after a few minutes. It then asks for the wpa password, searches for the router, asks again, and so on indefinitely, until I reboot and it all replays once more.

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.

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 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.

I recently purchased a UPS (Tripp-lite Internet 550U)to shutdown my PC during a power outage when unattended. This model of UPS is connected to the PC with USB. Upon plugging in the UPS USB cable the Gnome Power Manager started up and it appears to correctly show the condition of the UPS. During a power outage it showed battery discharge right down to the battery going critical, but never shutdown the PC. I have set the options in the power manager for low & critical battery shutdow. Seems something is blocking the Gnome Power Manager from shutting down, but I have no idea where to start looking..
PC: Abit mobo with Phoenix bios
Ubuntu 8.04
UPS: Trtipp-Lite Internet 550U

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.

is there a way to configure shutdown on critically low battery to give me a bit of time before actually shutting down?I've set Gnome to shutdown on low battery. Problem is, I don't get any notification about battery running low, and as soon as battery level reaches the critical threshold, the system starts shutdown without me having any possibility to quickly complete some tasks. Of course, I'd increase battery level thresholds accordingly.

I run Ubuntu 10.04 on a HP dv2000 laptop with 2GB RAM. I see a strange problem with my system. When running on battery and the level hits about 43% (+- 1%), the system shuts down suddenly. No warning and no information in logs either. Temperature of both cores are below 50 C. I have tried cleaning the dust withing the laptop chasis but no progress.
I have done quite some research on this and other forums but haven't found anybody else with similar problem.

after having far too many problems with other brown-coloured distros, I moved my MythTV box to SuSE (what all the other machines here use). Everything is working, EXCEPT for one thing: automatic idle shutdown. I cannot get MythWelcome to shut down the machine automatically (choosing shutdown now from it's menu does work). The log shows sudo: sorry, a password is required to run sudo (sudo -n) or the infamous "no tty and no askpass". (plain sudo)
I have added /sbin/shutdown to the sudoers file, and I can run sudo /sbin/shutdown -h now from the terminal and shutdown without a password... but sudo will NOT run from mythtv. I've even tried adding a special exception to the sudoers file, "Defaults !requiretty" with no luck. This is a dedicated frontend/backend with no user access (doesn't boot a desktop manager; goes straight to Mythtv) so I'm no too worried about potential security; the machine is on a LAN and cannot be accessed from the WAN side.

Is there a way to take a screenshot just before the "shutdown" terminal command? for example "sudo shutdown -h 90" for 90 minutes timer shutdown, and just before turning off to take a screenshot.

I have installed Ubuntu as wubi (next to windows 7). When I expect the computer to shut down (either to hibernate or as part of, you know, shutdown), it doesn't. All the programs end, I am logged out, but I still have a picture on the screen (ubuntu default picture).

I found this script on another forum post (HERE) from a couple of years back.It doesn't work anymore for some reason and I'm looking for some assistance in making it work now. I really need to cut down my electric bill and my son is constantly leaving his desktop on for hours on end.Any gurus out there up to the challenge?I am attempting to re-write the "inactive=" line using w instead of who but I'm not having much luck yet.

I've installed CENTOS 5.3 on my laptop, on dual boot with windows xp. The problem is that my wireless network manager doesn't find any networks. Another laptop with fedora 10 installed finds the network, so the problem is not the network. I guess it's a problem with the wireless driver / firmware, as i had this problem on fedora some time ago, and i've solved installing the firmware. Now i've installed the firmware, i rebooted, and it still doesn't find any network.

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 ?

I need a way to kill my battery in my Ubuntu laptop. Is there any mind numbing tasks I can Ubuntu do that will eat up the battery? I have already shut off the power management options. The battery is giving my issues and and someone said I should discharge it fully an recharge it from 0.

Since I had updated to Lucid, I'm having some trouble with running my laptop on battery. It usually turns off when the battery notifier is still at 13%~18% (it is not shutting down, it is like when your battery runs out of energy). First I had thought that was a problem with the notifier and I was missing when the battery had no charge, but I kept looking at the notifier and suddenly when it had reached 15% my laptop just went down, without saving any job.
I've just upgraded to Lucid Lynx, running on a HP Pavilion dv4-1123us with 2.00 GHz Intel Core2 Duo T5800, 4GB RAM.
The battery is a 6-cell Lithium-Ion that came with the laptop.
I'd bought it about 1 year ago.

my laptop battery capacity has gone low due to constant charging or whatsoever reason. previously it was at 62% and within 2 months its gone down to 32%. I use the laptop atleast for 18hrs every day. so is ther any solution to prevent my battery from losing the capicity.
i use dell studio 15 laptop, with 3 gigs of ram, lithium ion battery(56Wh), ati card, using compiz, p8600 processor. i use this for app development and for listening to music and videos.

So I've been using Ubuntu on a Toshiba L645d, and after a few hiccups with the sound and wireless, it's finally working well now. However, the battery is still a bit less when compared to Windows 7 (2:00 vs 2:35, but it came with optimizations on W7 so that might be the reason. A comparison of power used: 25w of power on Ubuntu vs 17.5 on W7.

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):
Code:

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...
