Debian Configuration :: ACPI - Battery Charging State Missing ?
Aug 9, 2011
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.

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.

I have a dell inspiron 2200 that has a pentium dual core and have been running Fedora 13 flawlessly I just noticed recently that my battery wasn't charging. It says battery fully charged at 0.0? And some days can't really recall it charges is there a way to fix this? I am running 2.6.34.7-56.fc13.i686

Can't get my battery to charge, it reads that it may be broken (about 20%).It reads that it is charged but when I go to details it reads charged but no watts.Also the time and menu commands at the top of the screen are not readable.they seem to be black on black text. This may be something stupid I have done...Toshiba Satellite pro L300 running natty

Is there a way I can specify at what percentage i can make my battery to start charging? I guess the default it 95% which ends up wasting a lot of battery cycles.And my second question being can i have different modes like power saver,performance?

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'm running Windows 7 Enterprise and noticed something new. The system icon for battery life is showing "plugged in, not charging." Does this oddity occur in Fedora too?

During boot (and in dmesg) I get the following message:
[6.782835] ACPI: Invalid PBLK length [7]
Also possibly related, whenever I close my laptop lid, kacpi_notify and kacpid eat up the cpu, and the screen doesn't actually blank.

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?

My ACPI and KDE Battery Monitor both report my battery as being 78% charged, even though I normally use it plugged in and it should be fully charged. I've found a bug report of the same thing in Ubuntu, but it seems to only happen to Sony laptops and I'm using a Lenovo G560. Plus, the bug is pretty old. Does anybody have a clue how to find out if my battery really isn't charging or if it's a software problem?
The bug report is here: [URL]
It seems to occur with laptops with "smart" battery configuration settings in Windows. As I've never had Windows on this computer, that possibility is already shut out.

If I click on the battery icon and then click laptop battery nothing happens. Does anyone know the cause? Or even what program controls this so I can run it in a terminal and see what is going on?

This link, acpi: thermal/sysfs-api, explains how the new thermal management sysfs class is built, but doesn't give much information about using it. Using watch, I can see that the cur_state of cooling_device2 changes from 0 to 5 when I check "Dim display when idle" in Power Management Preferences. But I haven't found an applet that changes cooling_device0 or cooling_device1.
Echoing different integers to the cur_state files limits the maximum cpu frequency for cpu0 and cpu1, respectively. This behaviour is expected from what I've read, and mimics the options in Windows power manager for extending battery life by throttling the CPUs. I've had no luck with google and local man pages, so has anybody has seen an applet for controlling /sys/class/thermal/cooling_device[0|1]/cur_state?
On a side note, a value of 1 does slow the CPU down, but it will still hit 100C (normal for an Intel mobile duo core). However, values of 2 and larger throttle enough to lower the maximum CPU temp. Since the CPU temp is a good indicator of power consumption, it's pretty obvious that these two cur_state files are intended to extend battery life. dd_wizard

i did an install of squeeze without selecting anything during tasksel. after install i changed my sources to testing, updated, and did a dist-upgrade. i then installed xfce4 and xfce4 goodies. i noticed some of the xfce4 packages have the current state 'pa'. for example:
[Code]...
this makes me worry some things didn't install all the way, because if i did aptitude install xfce4-power-manager it would install it and leave make the current state 'i'.is there anyway to install all the packages labeled 'pi'?

Code:
I have just inserted a new battery. However, there is no settings that show the capacity and current charge time, etc.
When I click the battery icon. All I get is the current percentage.
Is there anything that will give me more details about my battery i.e. capacity, charge rate, time to full charge, etc?

My brother gave me a copy of Ubuntu 10, since my upgrade from 7.04 to 7.10 screwed up. Installed it easy. But strange problems occur. After a few minutes of starting the system, it enters a command prompt, regarding "Checking batter state" yet my computer runs on an adapter, no battery exists (except the built-in one on the motherboard), and I have to restart my computer.

I recently bought a Toshiba Satellite L650-BT2N23 laptop (i3-core, 4GB RAM) and have Fedora 14 (kernel 2.6.35.6-45.fc14.x86_64) installed on it along with Windows7 64 bit. I am having a hard time getting linux o detect the battery, even when the laptop is running on battery power. The battery appears as not present and the power management applet always indicates that the laptop is running on AC. Setting acpi=on or acpi=force did not remedy the problem, neither did disabling acpi altogether (acpi=off). I have 'Insyde H2O BIOS' version 1.70, which appears to support acpi.

I had been doing some removal of packages, and things went well, or so I thought. Now whenever I try and install any package using aptitude, some old state is lingering around and wants me to install packages that I do not want, and remove some packages that I am not sure about removing (did I actually select those to be removed??) I removed libvirt etc, and now it wants to come back? Also, like I mentioned, why remove those other four packages?
The following NEW packages will be installed:
aqemu gtkrsync libvirt-doc libvirt0 python-libvirt qemu qemu-kvm qemu-system qemu-user qemu-utils virt-top virt-viewer virtinst
The following packages will be removed:
dnsmasq-base{u} netcat-openbsd{u} python-gtk-vnc{u} python-vte{u}
0 packages upgraded, 13 newly installed, 4 to remove and 176 not upgraded.
Need to get 2,210kB/24.3MB of archives. After unpacking 72.7MB will be used.
Do you want to continue? [Y/n/?] ^C
Running squeeze, and enjoying it so far, apart from a broken out of the box synergy (compiled my own synergy-plus to fix that issue) and a buggy samba client.

Updated from 10.04 to 10.10 about 2 weeks ago and it worked just fine until today. After rebooting, it's stuck at "* Checking battery state" and nothing happens. I've tried with power cord inserted/out and without battery but with no success.
What I did before rebooting was that I tried to fix my iphone tethering problems with the following commands:
And also a system update. And here I am. Anyone knows what could have happened? I'm on a Acer Travelmate 8371.

Every time I try to boot into Ubuntu, it never goes any further than Checking battery state. Once it gets there it pauses for about 2 minutes then goes to and doesn't go any further. I can still press CTRL+ALT+F(1-6) to get to a command line, but I'm kinda n00bish when it comes to the command line.

Today when I went to boot up my computer, it hung at "Checking battery state...". I have never had any problems before this, and have been using 10.10 for several months. The only change I made that I can think of was installing the Wacom Control Panel. I have no idea what to do, and really, really don't want to reinstall Ubuntu unless there's no other option.

I upgraded from 10.10 to 11.04 last night.
The boot process hangs just after 'checking battery state' and I can't reach the login screen.
I can boot in using an older kernel OK.

I upgraded to 11.04 yesterday but when I try to run it now it freezes on checking battery state. I've did some looking in the forums and found this post. [URL] Which in turn pointed me to this page. [URL] I have an ATI Radeon 5450 so I went through the steps for Need to fully remove -fglrx and reinstall -ati from scratch
Now, when I try to start up the screen just goes blank as if I've turned the computer off. I can run the system in limited graphics mode (or whatever it's called) so I have the ability to do some troubleshooting there, but I'm a Windows convert and am pretty hazy as far as Ubuntu troubleshooting goes

My linux laptop isn't able to detect the current battery state. I am using slackware64 13.37 xfce with a Toshiba L645 laptop.
This is what I came up with so far.
Code:
lsmod
Module Size Used by
snd_seq_dummy 1479 0
snd_seq_oss 30116 0
[Code].....
I use a program called conky that reports my cpu frequency and most of the time it's always at 0.93GHz instead of 2.53GHz. Sometimes it jumps to 1.20GHz and 2.53GHz but falls back down to 0.93GHz. Is this normal?

I can get to a terminal with it in this state and use a ps aux [pipe] grep acpi and kill processes but how do I get it to resume booting after this? Typing startx doesn't work as xserver is already running on screen zero displaying the never-ending loading screen.

How do I check the state and health of the laptop battery. In Ubuntu it was just a simple task of clicking on the battery icon on the task bar and your info would come up. With Fedora 13 nothing happens..

So much for an LTS release being stable. I try to boot from a LiveCD and it hangs on "Checking battery state..." I searched the forum for a solution but didn't really find anything. This is an old desktop machine with Intel onboard graphics -- nothing too fancy and nothing it should have a problem with. Yet it's not working.

I just installed Ubuntu server 10.04 LTS on Dell Optiplex 380 with gnome desktop.
After setting up Samba, I disable gnome desktop from start up by eding GRUB config file.
Everything works just fine.
But this evening, when I tried to boot my server it hanged for about 3 minute with
Code:
After that come the login. After I inputed my user and password it hanged again for 1 minute than it displayed a message saying
Code:
Login timed out after 60 seconds.
I tried to login agian and again but end up with the same error message.
I was sure i typed the correct user and password.

In Jessie I would change the "critically low battery value". So from dconf-editor I followed this path:
Code: Select all/org/gnome/settings-daemon/plugins/power/
as suggested here [URL] ....
and here [URL] ....
The problem is that I haven't none of the following fields:
time-action
time-critical
time-low
or
use-time-for-policy
percentage-action
percentage-critical
percentage-low
How can I overcome this problem? Why the dconf-editor seems to be incomplete?
