The display becomes less bright when on battery than on AC power, but I already unchecked "Reduce backlight brightness" on the power management setting. What else can affect the brightness?
View 5 RepliesSo my display keeps dimming on even when plugged into the charger.The option to dim display is unchecked in power preferences, it gets really annoying when I'm trying to watch a movie.

However I'm still looking for a method that can automatically disable screen fade while watching videos in a browser. I don't want to permanently disable the powersaving idle method. I have both cpufreqd and laptop-mode-tools to conserve my powers.
View 2 Replies View Relatedgetting 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.

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.

How can I disable this check so that the laptop will still boot without a battery fitted?
Just installed openSUSE 11.4 which comes with KDE 4.5. It has taken a while for me to find my way around and I am still trying to change settings so that VLC is default multimedia app rather than Amarok or similar. how to turn off the jerky dimming effect which was being applied when I close a window. Out of interest does anybody know what memory and cpu overhead these effect costs and how many lines of code? More to the point does anybody know who needs them?
When using Dolphin with column view does anybody know how to have the left margin shown rather than the right. As it is now, with long files names, the right hand end of the filename is shown and to see the directories I have to use a slider to scroll back to the left. I do not recall this being the case before. It used to be that the long file name was cut off unless one scrolled. In that way you could see all the directories and when moving files life was simple. Now this is not the case and actions take longer.
I've recently installed Squeeze on my laptop. All was fine (except for a small change I needed to make to the GRUB code in order to install and boot it) and I find the OS easy to use. I am sure I will be using it for a long time! I might even change my desktop over to Squeeze as well - I'm using Linux Mint 10 at the moment.I have found just one minor problem: the battery icon continuously shows 100% full, even when the indicator on the laptop is showing that it needs recharging - after about two hours' use.This has not happened before:although the laptop is about two years' old, I have had this battery for only a month, so it has not yet done much work!

How to set battery charge thresh ?I use thinkpad w500 with Debian 6 .
View 1 Replies View RelatedI have looked all over the place but I can't find if this is possible. I am running Debian 6 as a media server (SMB) and it is tied to a UPS, I used gnome power management to set up a low battery shutdown but this UPS also is powering another embedded computer. So, I was wondering if it was possible to have a script run (to log in and shut down the embedded system) before gnome power management shuts down the Debian server. I know I could probably get it to run on every shutdown, but I am looking for low power only.
View 1 Replies View Relatedis there a way to configure shutdown on critically low battery to give me a bit of time before actually shutting down?I've set Gnome to shutdown on low battery. Problem is, I don't get any notification about battery running low, and as soon as battery level reaches the critical threshold, the system starts shutdown without me having any possibility to quickly complete some tasks. Of course, I'd increase battery level thresholds accordingly.
View 3 Replies View RelatedI 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:

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 ?
when running on AC-power, only on battery.When I have my laptop on battery, and I plug the mouse in, then the USB mouse is working if I keep moving it around. If I then lay it alone for 5 secs, or so. it stops working.I cannot get USB sticks to work as well.
View 3 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

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.
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 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...
I'm using Debian Xfce. Packages already upgraded from testing repository. The problem is while acpi command says correct result, the battery indicator in notification tray doesn't. Unplugging or plugging the power cord, the indicator doesn't change.
I added battery monitor (right clicking panel - add new item - battery monitor), same behavior. I already googled, no solution yet.
I went cold turkey from 7.6 to 8.3 (needed to re-partition anyway)..reformatted etc. I'm seeing this in my logs:

I have Etch running in my laptop. I found that if the laptop is only running on battery, the disk seems to performs slower than if I running on a power adapter. How do I possibly check the setting and fix it?

I got a brandnew Acer Travelmate Timeline X (13"). I do not really know if this is the right topic for my problem. But here it comes: The Acer uses a special smart battery with special chips in it controling the powermanagement of the battery and the system. In general there is a kernel module to handle this (sbs). But for me this does not work.I am using Squeeze and it does not recognize the battery. It always acts like being on AC power. If I unplugg the AC it runs with the battery till it is empty. But the ACPI can not recognize the battery and can not read how much lifetime it has. I tried the reassambling method. But this method does not work for me. Nevertheless I think the reassambling method does not run because there is no more developing on it because of the kernel modul.
What can I do? Will I have to wait till a new workaround of sbs comes out, which can handle my battery? I read about a BIOS hack that disables the smart battery functions. Should I try this? But I am not really firm in that kind of stuff and I will loose the guarantee. Has anyone got an idea?
