Ubuntu :: Battery Not Charging And Greyed Out Menus?
Jun 2, 2011
Can't get my battery to charge, it reads that it may be broken (about 20%).It reads that it is charged but when I go to details it reads charged but no watts.Also the time and menu commands at the top of the screen are not readable.they seem to be black on black text. This may be something stupid I have done...Toshiba Satellite pro L300 running natty

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.

Is there a way I can specify at what percentage i can make my battery to start charging? I guess the default it 95% which ends up wasting a lot of battery cycles.And my second question being can i have different modes like power saver,performance?

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.

I'm running Windows 7 Enterprise and noticed something new. The system icon for battery life is showing "plugged in, not charging." Does this oddity occur in Fedora too?

I have a wireless headset that I'm trying to charge through USB. When I connect it, it just doesn't charge. Looking at dmesg, the device isn't recognised, which is not surprising, since I think the USB port is only for charging, and it won't communicate over USB. lsusb also tells me that (apart from other things that are connected to the USB bus, that all of the 'MaxPower' variables are set to 0mA. So what I think is happening is I connect the headset ubuntu queries it, receives no reply, and so doesn't let the port draw any current. As far as I'm aware, there usually is some kind of OS handshaking like this, but it may vary from model of computer to model, so there's no point in saying "my <INSERT USB DEVICE HERE> charges". I am able to charge my MP3 player from the same port (because it's recognised), and I can charge the headset if I use a dumb mains->USB/5V transformer, but it should also work with my laptop. What I think I need is some way of manually setting the 'MaxPower' on the USB ports.

I have a dual boot with Windows XP and Ubuntu 10.10. I connected my Amazon Kindle to an USB interface in XP and in Ubuntu. From XP everything works with no flaw. In Ubuntu the data exchange is perfect, but the device does not charge.

I didn't know that charging via usb for my sony ericsson mobile, w880i actually needs the SE PC Suite to be installed, cos, I used to charge it via usb cable, as mentioned, on my workstation, which is window based, it's kinda insignificant to me that the software has to be installed first.
However, I'm currently on the move, with my newly installed "netbook", I installed Ubuntu 9.10 on my twinhead efio 121A (which is good, no compatibility issue) and now, I just figured that, SE PC Suite does not have any linux version, but my mobile is already out of battery, and I desperately need to charge it,
I did run a lsusb, it doesn't seem to detect the phone, neither as usb storage, or as a phone, cos, I saw other people lsusb output, it's an item with "sony ericsson", but my output does not have such item. However, when I plug in the usb cable, it did prompt to ask me to choose between "file transfer" or "phone mode".

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?

I 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:
gconf-editor
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.

I've searched for this a fair bit but everyone seems to have a different cause.
I constantly get applications greyed out. (I understand this is when ubuntu sees them as 'not responding') It happens to Firefox a lot, but that may just be because I use it alot. It happens to Nautilus a lot too, and sometimes the everything gets grey at once.
Windows, every other OS I've ever had installed (including older Ubuntus) and the 10.04 live-cd all run fine. So I'm under the impression that it's something either that i've installed or that ubuntu did when it installed.
It's done this pretty regularly from day one, so it doesn't seem to be something I've done lol.
What possible causes are there for this? Is there a log or something I can check that may enlighten me?

I'm trying to use Open Office presentation, and it makes me angry and a little disappointed because it feels like it is everything else than user friendly...Like 50% of all the options are grayed out and it is really irritating!It started when i tried to view the presentation, and advance to the next image by pressing the mouse button like in power point, and it is so bad layout i don't understand how, and it makes it even worse when i can't click 50% of eventual solutions.

I have done a clean install of Ubuntu 10.04 on my laptop. However I don't like Evolution mail client and installed Thunderbird from the repositories. It installed fine and comes up with the wizard to fill account details in but for some reason you can't input anything from the keyboard - it seems greyed out. I tried uninstalling and re-installing but it's still the same. Everything else is fine and working.

Running Evolution 2.23.3.1 on a laptop with 8.04 installed. (Running 8.04 for good reasons - please don't query). I've been running perfectly for some time, but today when I booted up and opened Evolution to check my mail, the first sign of something odd was that it didn't ask me to unlock the keyring. Then I noticed that the send/receive was greyed out.
I rebooted several times with no change. I've clicked on Permissions in the File menu, but that doesn't then show any window, which is what I would expect, thinking that something has changed. Other than accepting all the usual update manager's recommended installs, nothing has changed on this laptop for several weeks.

ubuntu 11.04,Windows 7 dual boot. Almost total linux / ubuntu novice.I just installed ubuntu 11.04 this afternoon. The installation went smoothly but I did not get wireless internet connection. In the top panel : Network device not working (firmware missing)Some hunting indicated that one needed to remove some files and install some others using synaptic. Found synaptic, loaded it by clicking and found the file to install. However the Package Tab was completely greyed out. Any suggestions where I am going wrong?
BTW the 11.04 is different enough that I have not yet even found the terminal so any suggestions re it, please include a suggestion on how to find it.

Recently upgraded to Karmik and use KphotoAlbum version 4.0.2 for photos.On startup error messages says "exif2 library" not installed. Synaptics package manager indicates it is installed. The end result is that "Images" plug-in is grayed out and exif searches cannot be done, resulting in photos being displayed out of order.I used "Ubuntu Software Center" to install package.

I'm the only one using this pc, so I want to enable automatic login. When I open the "login screen settings" though, it's greyed out (inactive) and the "unlock" doesn't do anything.
I also have something about "keyring" asking my password each time just after login, which isn't pleasant.

I'm trying to burn the .ido of Mepis 11 to a DVD. I have a 4.7Gb DVD-R in the drive. Usually, I would just navigate to the .iso and select it, and K3b would do the rest. Now, when I do that, K3b does check the md5sum, and it's correct, but then it just sits there with the Start button greyed out.

Just installed Centos 5 and I'm wanting to learn. However I also need this machine to VPN to work. When I go to Network Connections and click on the VPN tab the button to "Add" a connection its greyed out.I've googled and tried a few things in terminal with openvpn, pptpd client, poptop, but now I'm more confused than ever. I think the problem is most of the pages I hit are how to create a SERVER on the Centos 5 box, I just want to be able to vpn into work, so I'm assuming a client?My question is
1. Is there a gui interface for a quick VPN connection?
2. If not, what is a help doc with just the connecting side of the puzzle?
I have a 2nd computer with Windows on it that was preset up on VPN for me.

I recently reinstalled Debian Lenny. Now, many images are greyed out. For instance, I can't see graphs in Google Analytics; can't change time period.Also, some video sites require the latest version of Flash. When I go to Adobe download, I only see *.debs for Ubuntu. But I'm not sure which version of Ubuntu is compatible with Lenny.
