Ubuntu :: Upgraded To 11.04 - Freezes On Checking Battery State

May 1, 2011

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

Ubuntu :: Laptop With No Battery - Checking Battery State

May 1, 2010

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?

Ubuntu :: Lucid - Checking Battery State?

Jun 15, 2010

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.

Ubuntu :: After Rebooting - Stuck At Checking Battery State ?

Oct 26, 2010

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.

Ubuntu :: 10.10 Not Booting Past Checking Battery State?

Dec 26, 2010

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.

Ubuntu :: Boot Hanging At Checking Battery State

Jan 16, 2011

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.

Ubuntu Installation :: LiveCD Hangs On Checking Battery State

May 6, 2010

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.

Ubuntu Installation :: Edubuntu 10.10 LiveCD - Checking Battery State - Can Not Mount

Apr 14, 2011

I am having a hard time installing Edubuntu 10.10 on a Toshiba L30

System specifications:
Toshiba L30-140
Intel Celeron M CPU 410 1,46 GHz
ATI Radeon XPress 200M Series
Bootable with CD/DVD only

While installing Edubuntu, I encounter two problems:

Can not mount...

I will reach to the screen to select to install Edubuntu and it will even show the green leds. I push F1 to get more detailed messages. After 2 minutes or so I will have this error message:


This error appears randomly. Out of ten attempts to boot, 6 times I will get this error message. 4 times I will get to...

Checking battery state ... [OK]

This will advance up to "Checking battery state... [OK]" which will freeze there with no DVD or HDD-Activity visible.

I encountered very many threads on the "checking battery state" issue, but they seemed obsolete to me, since most of them referred to Ibex. Also this is the Edubuntu LiveCD, it has not yet been installed on the HDD.

Nonetheless, for the Checking Battery State problem I have tried solutions for Ibex such as "acpi=force pci=noacpi" and "acpi=off". But it wouldn't work. Some people also suggested changing the graphic configurations, this is ATI however, not Nvidia and the BIOS does not offer the option to change it.

Strangely, the installation has worked brilliantly (with the same dvd) on another computer (some Laptop Toshiba L30), so I don't believe it might be a damaged disk.

Ubuntu Installation :: Checking Battery State Is Crashing GNOME Desktop Frequently

Jul 12, 2010

Dell Optiplex GX260 (w/onboard Intel graphics) Original install was Ubuntu 9.04. Upgraded twice, first to 9.10, and 2 months or so ago to 10.04. Problem never occurred before version 10.04.

BUG HISTORY: Googling on this problem reveals that it has been around since at least Ubuntu 8.10.

I'll be working away and all of a sudden the entire desktop blows off the screen and is replaced with a console stuck in a loop. The last message I always see in the console is "Checking battery state", then the endless looping begins.

The only way out is CTRL+ALT+SYSRQ+K (kills Xserver, I think) followed by CTRL+ALT+SYSRQ+B (reboots system).

NOTE: If I attempt to restart Xserver, Ubuntu goes into an endless console loop with the same "Checking battery state" message. Does that help anyone figure out what's going on?

I have tried to remove any laptop program that manages power and they uninstall ubuntu-desktop. What gives with Ubuntu's GNOME being dependent on laptop utilities? I'm running a desktop and have no need of laptop utilities.

I have gone to the extreme of starting Ubuntu in Recovery Mode, dropping to a root shell with networking, then removing GNOME and Xserver completely and re-installing them both. The problem STILL occurs.

I have used the following commands to accomplish this:

This problem has made Ubuntu extremely unreliable, as it can crash at any time and DOES... MANY TIMES in a day!

Ubuntu Multimedia :: 2 Video Cards - Boot Hangs On Checking Battery State

Jan 5, 2011

I have a Nvidia graphics card, and an onboard card. I wanted to use both concurrently. At first I was only getting signal from the Nvidia one, but I want both. I changed the settings in my BIOS to Onboard, but it is now only coming from my onboard one. I then installed the Nvidia drivers from Additional Drivers, and then boot hung on checking battery state. I had to remove info from xorg.conf just to boot.

Debian Hardware :: Lower Laptop Battery Charging State To Prolong Battery Life

Mar 2, 2010

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 reactionsŁ 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 MaintenanceŁ 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 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?

Ubuntu :: Checking Battery Level In Mp3 Player ?

Mar 19, 2011

I have an Archos Vision A15VS mp3 player which I am recharging through the usb connection of my laptop. Unfortunately, as far as I can see, there is no way of checking the battery state during the process as the screen of the player only shows a usb icon when the lead is connected.

This means that I don't have a visual confirmation that the battery is actually charging!

Obviously I could simply unmount the device, check the microscopic battery icon on the screen, and if not showing "full" repeat the process.

Slackware :: Laptop Isn't Able To Detect The Current Battery State?

May 1, 2011

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.

Module Size Used by
snd_seq_dummy 1479 0
snd_seq_oss 30116 0


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?

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.

Ubuntu Networking :: 10.10 Freezes When Using Wireless On Battery?

Nov 28, 2010

Unlike a lot of others, I have had no problems getting the wireless on my Dell Studio 1558 working with the STA driver. As long, as I am not on battery, that is. Within minutes of switching to battery and disconnecting from the LAN, my system freezes: I cannot move the mouse, the keyboard is useless (I can't even Ctrl-Alt to a terminal) and my only option is a hard boot.I currently have the 2.6.35-23 kernel and I have tried the following driver options for the wireless (all the below were tried with 2.6.35-22):

- the Broadcom STA driver in the repos- the latest STA dirver from Broadcom- the new broadcom driver, not yet available in ubuntu repos (brcm80211)- ndiswrapper ( I can only get win 7 drivers for my laptop, so this does not even enable the driver)My Wifi card uses the BCM43224 chipset.After a freeze, I have pored over the logs and I cannot find any obvious error messages preceding the event - so I am a little at wit's end ito resolving this. Can anybody give me any clues as to where I should start looking to resolve this issue?
