Ubuntu :: Laptop With No Battery - Checking Battery State
May 1, 2010Just 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?
Debian Hardware :: Lower Laptop Battery Charging State To Prolong Battery Life
Mar 2, 2010getting 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.
Ubuntu :: Battery Not Recognized On Laptop (and It Recognizes Laptop As A Desktop)
Apr 15, 2011I 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.

Ubuntu :: Laptop Turns Off When Battery Is Not Empty?
May 2, 2010Since 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.

Feb 24, 2011So 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.

Ubuntu :: When Running Laptop On Battery Desktop Freezes
Oct 16, 2010When 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.

Debian Hardware :: Driver For Battery In Laptop?
Feb 17, 2011When 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

Ubuntu Networking :: No Wifi/ethernet After Battery Died While Laptop Was Asleep?
Jan 10, 2011Running 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?

Fedora :: Laptop Battery Status Not Displayed Correctly - 11
Nov 2, 2009Recently I installed FC 11 on my laptop. The OS is not displaying the battery status correctly in the notification area. if I remove the power cord after 100 % charging, the status remains the same even during discharging. It never informs me the correct discharge status or any warning when the battery power is critically low. This is causing unexpected shut downs and data loss to me. Is this a bug ? Do we have a solution for this. My laptop is Compaq CQ40-327TU; dual boot with Vista as alternate OS.

View 6 Replies View RelatedHardware :: Laptop Battery Discharges Even With A/C Adapter Plugged In
Mar 24, 2011A couple of days ago, my laptop battery starting discharging at random times. I could rectify this by either pushing the A/C cable in or rotating it slightly. Now the battery discharges unless the A/C cable is pushed in constantly. A few months ago I had a similar problem, though it was accompanied by the computer randomly shutting off. The battery had to be removed and reinserted before I could successfully power the machine back on. Purchasing a new A/C cable fixed this problem quite well. I suspect it may be the battery this time. The gnome battery monitor in LMDE is going completely nuts, announcing I have five minutes of power left and then happily informing me that I have 10 hours 42 minutes only a few moments later.

CentOS 5 :: Laptop Automatic Shutdown On Low Battery Not Working
Aug 28, 2010I'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.

Dec 14, 2010Lately, my laptop has been encountering instant death. Completely powers off, the end, good night. This happens a couple times a day. After these deaths, the laptop will not turn on unless the battery is removed, the A/C power cord is unplugged, and then both components are put back in. Judging from this, I think I need a new battery and possibly a new power cable. Buying new ones for my laptop, though, comes out to about $100, and I'm informed that my particular laptop model has been known to have some issues. (It's an ASUS x83v)
