usually when my battery gets critically low, The system warns me to plug it in, and then it hibernates. But recently, It displays no warning, and instead of hibernating it just shuts off. It still displays the "20 minutes remaining" libnotify warning, but thats not useful if I'm doing something fullscreen.
View 1 RepliesI'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
If I suspend this toshiba satellite, and the battery is or gets low it will wake from suspend to tell me that it will need to suspend due to a critical low battery. Which is pretty dumb. I've experimented with this by plugging and unplugging the ac adapter.

View 1 Replies View RelatedJust 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've just upgraded to Natty. During the upgrade no errors showed. However, when I now boot ubuntu (either recovery mode or normal), the boot process hangs at:
'checking battery state'
I searched for similair problems in this forum, but the solutions in other posts(sudo apt-get update & upgrade etc.) did not help. I'm not sure if it is related or important, but when it hangs, it also shows something like:
'starting automatic crash reporter [fail]'
'not starting jetty'
'saned disabled'
(I can't copy there of course, so it is probably not exactly like this, or in this order...) What can I do to get my ubuntu boot again?
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.
Hibernating windows 7 on dual-boot laptop (9.10 Ubuntu - W7) writes something on MBR which breaks GRUB2. GRUB2 does not load at all after hibernating W7 and the best solution is to reinstall GRUB with Ubuntu 9.10 cd, just follow the instructions at [URL]

View 1 Replies View RelatedI followed a guide with the hopes of my computer waking from suspend after a defined number of seconds (for testing purposes, 4 seconds).
Per the guide, I've added a file: /etc/pm/config.d/00-use-suspend-hybrid
Code: Select all# Always use suspend_hybrid instead of suspend
if [ "$METHOD" = "suspend" ]; then
METHOD=suspend_hybrid
fi
# The delay after which hibernation gets triggered (default: 900 seconds, 15 minutes):
PM_HIBERNATE_DELAY=4
After four seconds of suspend, it continues suspending, and doesn't go into full hibernate.
Does Debian support Hibernation? I have a home file server, I'd like it to hibernate (and use least power as possible) when not in use. To access remotely we'd use wake on lan. I couldn't find any how tos on the wiki.

View 4 Replies View RelatedI have a 3 year old laptop with the original battery and its drained pretty bad. The "Battery may be broken" popup was driving me insane and this is how you disable it, in case you are in the same situation as me. Open terminal
Code:

Drill down to...
apps --> gnome-power-manager --> notify
uncheck the low_capacity checkbox. This should disable the popup for you if your battery has little life left in it. Now, if any knows how to disable the Avahi popup, let me know.

Ubuntu - 10.04 LTS
zlib - 1.2.5
Why does GNOME fail to start correctly after compiling the latest version of Zlib?
I have analyzed the situation. Zlib does not change or delete any file on the file system.
I have asked this on three occasions over the last 8 months and no one has been able to give me an explanation, so it would be a great challenge for the Ubuntu lovers. I am also EXTREMITY interested to find out why, because I have had a hard spot negative opinion against GNOME since this occurred.
I recently installed Ubuntu and wanted to remove the Windows XP installation is was dual booted with (I used Wubi to install Ubuntu), but I ended up just editing boot.ini to remove it from the boot menu and automatically boot in to Ubuntu. But then, Ubuntu started playing up and keeps on popping up with the Critical Temperature warning, saying it's 80-100C although it's the first time it's been turned on in 14 hours... But to add to my confusion, when I try to boot from ANY disk, it comes up with "NTLDR is missing" and a restart message.
View 2 Replies View RelatedI don't know why but sometimes zypper (v1.4.5) removes some of the installed packages before upgrading them.
Actually it removes it even before downloading a newer version. I just wonder what a stupid f**k implemented this behavior. I wish something awful happens to him.
An hour ago I tried to update few packages, among those were sysconfig, firefox and yast. Guess what? Zypper removed those before downloading newer versions. Due to a temporary network connection loss zypper could not download packages and quit leaving me without firefox, without yast and, what's even worse, without sysconfig package which contains essential system scripts such as ifup, ifdown etc (so my network went down completely without a possibility to restore). It's a big luck there was no new package of rpm (or it would be removed by zypper too) so I could just download those packages with my second PC and reinstall them from a memory stick.
Now I'm interested where should I file this bug, because without a doubt it's a critical one.
I started to use the smart plugin for munin to monitor my HDD. I changed the script a bit to report the raw value instead of the value for Power_On_Hours and temperature. It all works.
However, it now reports the values for these 2 sensors as critical, even though the power on hours is 928 and threshold is 999 (I even tried 9999) and temperature is 51 (threshold is 60).
I got the same error while installing (even though install works fine!) during installation and after it. Its Critical temperature reached, 3564 C, shutting down. Celcium value is not made up, its actually among those lines (four-digit).
I had another problem with installation, but I managed to install using nomodeset setting. My pc is a rock laptop (which is actually supposed to work well with vista instead.. oh wel..).
Any suggestions? I have tried installing with acpi=off, but it doesnt make any difference during installation or after it..
Also another error I got during some of my tests was: "init: Failed to spawn rc-sysinit main proccess: unable to open console: input error
Fascinatingly weird one here. First, this issue isn't on my computer, it's from someone who I am helping. I don't have first-hand access to the computer. Some background: the machine originally had Ubuntu Hardy, which we upgraded to Lucid a couple of weeks ago. Earlier this week, he gave me a call that Ubuntu wasn't booting up; it dropped to the command line. Some tinkering later, I figured out that libgthread-2.0.so had become corrupted, so X wasn't starting. It gave an error complaining that it had an invalid ELF header.I figured that this was just an odd freak occurrence; there was a bad kernel panic previously, so maybe the library was upgraded and the system was just writing to the disk at that time. Fixed via sudo aptitude reinstall libglib.
Ubuntu then started and everything ran perfectly. Today, he gave me a call. After he had restarted the computer, Ubuntu again dropped to terminal at the same point while booting. I had him open a new tty and run startx, which failed with a different shared library but the same error: libXext.so.6 has an invalid ELF header!
We had run updates, but I don't recall whether X's shared libraries were touched. Even if they were, though, that shouldn't affect anything. There were no hard resets between my fixing libgthread and libXext breaking. I'm going to try a clean install; I'm really just hoping we can figure out why this is, because it's an amazing little problem.
