Ubuntu :: When Running Laptop On Battery Desktop Freezes
Oct 16, 2010
When I'm running the laptop on battery the desktop freezes. It doesn't matter what program I use, it also happens when I just boot the system login and do nothing. I then have no mouse, no keyboard - so no key combination works. The only thing I can do is turn the laptop off using the power button and turn it back on. Usually the desktop freezes with in 5 min after login, but I also had one case were I was able to work for about 2 hours. When I plug in the power supply everything works fine.

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'm using Arch Linux x64, Gnome Shell and have the newest updates.
What's wrong with my laptop? Where should I look for errors?

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 have an MSI Wind U120 netbook (Intel Atom N270 1.6GHz processor, 1 GB RAM). I'm running Ubuntu 10.10 Netbook Remix. Ever since upgrading to Ubuntu 10.10 from 10.04, my system has experienced unrecoverable freezes when running on battery. The system reliably freezes when resuming from the suspend or hibernate modes when running on battery. It seems to load back up successfully but then freezes before I get a chance to enter my password. Yesterday and today I also noticed that the system freezes while idle and running on battery! This is even more disconcerting.
I have some experience as a Linux user (including using the terminal & editing configuration files) but not much experience as a Linux system administrator.

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?

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.

The screen of my years-old HP laptop (running Natty) freezes and eventually turns black. Ctrl-Alt-F# works to switch to the terminals. My fan is even louder than usual. I spend some time fooling around with ps and kill and shut down some of the most resource-consuming processes, which quiets the fan a bit, but tty7 still shows a black screen except for my mouse pointer.
I finally decide to shut it down altogether, but then I think to myself, "Self, you've used the power switch to shut down before in this situation, but shouldn't there be a more proper way to do it in the terminal?" So I try shutdown, I have trouble with it, it proceeds to get hopelessly tangled up, and it looks like it's frozen up in mid-restart when I throw up my hands and decide to go for the old power-switch-for-five-seconds method after all. Now when I start the computer and select Ubuntu from GRUB, I get this:

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?

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.

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

I have Evoluent Vertical Mouse connected via USB. It would work fine connected to my laptop on AC power, but it would freeze when on battery.I have "laptop-mode-tools" installed, and I traced this problem to laptop-mode-tools trying to put the mouse to sleep and not waking it up.To solve this, I have blacklisted the power management for the USB mouse. First, I did "lsusb" to find the mouse device:
Bus 002 Device 003: ID 1a7c:0068 Evoluent VerticalMouse 3..And got the ID of the device. Then I edited the laptop mode configuration and added this id to the blacklist:
/etc/laptop-mode/conf.d/usb-autosuspend.conf
edit this line:
AUTOSUSPEND_USBID_BLACKLIST="1a7c:0068"

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 have a Wubi installation, and the upgrade to 10.04 froze. I didn't note down the point at which it froze.
When I tried to reboot, I got the grub screen, and when selecting Ubuntu I get lots of text messages scrolling by, but it freezes at battery check.
The machine boots fine into Vista.
Rather than spend a lot of time trying to figure out what went wrong in the upgrade, my inclination is to delete the Wubi installation from within Windows, and then do a fresh install of 10.04 under Wubi. Is this feasible/sensible?
There are a handful of files I would like to salvage from the prior installation, however. Could I do that with a Live CD since the prior installation was under Wubi?

I did normal net upgrade after the official release of 10.10 yesterday evening. On reboot I get a frozen system with a blank screen. Checking via safemode, I find it is stuck when 'checking battery state' but this is a desktop machine! Apt update, uninstalling ubuntu-desktop, reinstalling ubuntu-desktop, etc.

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.

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.

Trying to install 10.04.1 Kubuntu desktop to Toshiba T110 laptop running Win 7, 4 Gig Ram, 32 bit o/s. Downloaded iso from Ubuntu web site and burnt DVD. No matter what I do I get the error message "cannot mount /dev/lop0 (/cdrom/casper/filesystem. squashfs" etc. Searched by Google and this forum, tried various remedies Unebootin; USB drive boot up etc etc; still get same message. Is there a workaround for what seems to be a fairly common install problem?

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.

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.

Running Ubuntu 10.04. Networking won't work at all. Used to work flawlessly. Problem is not hardware, because booting windows (vista) on the same machine I can still use networking.
Little story: I Was going into a short trip, then I put my computer to sleep (as usual). Trip took longer than expected and, when I came back, the notebook battery was dead. Charged it, booted the notebook (Dell Inspiron 1525) and now its network won't work at all. After reboot it even ran a filesystem scan, but problem wasn't fixed. The icon on 'taskbar' only says "networking disabled". The ethernet lights won't even light up when I connect a ethernet cable and it won't see any wifi networks. I've tried to fiddle with that little switch which would turn the wifi on and off, but all it seems to do is turn the Bluetooth on and off, as shown by the little Bluetooth icon on 'taskbar' (I've not tested bluetooth, though). I've also tried to plug a external wifi dongle but ubuntu won't even try to install it.
what's happening or what could I do to get my network working? Is there some 'magic' I can type into a terminal window to make this work?

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...
