I installed the latest version of puppy linux on this Nobilis laptop and I am having a little trouble with the battery. As you can imagine being able to see the battery power left is a bit more then convenience. I am running it frugal install. Is there just a setting or something that I am flat out missing? I used the Hardinfo hardware information tool (A tool in puppy linux) and it also didn't find the battery.

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.
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.

View 2 Replies View RelatedI was using a friends laptop and decided to boot into an install of tinycore on a flash drive. This laptops battery is already pretty much shot because it is left plugged in all the time no matter what the use, and before I booted into it the level was at about 60%, which means about 40 minutes in windows. When I booted into tinycore, there was only about 10 minutes before it shutdown completely. I noticed the fans were on high and the air coming out was rather hot, but why does that happen?
View 1 Replies View RelatedI'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):

What's wrong with my laptop? Where should I look for errors?
I've been using Ubuntu for the past four years, but I recently bought a Dell Mini 1012, and while Ubuntu 10.04 is wonderful in every way, it is giving me quite poor results in terms of battery life, compared to Windows 7 which is also installed on the device. I have been able to get 4.5 hours out of Ubuntu,compared to the 8 hours I have been able to get with Windows 7 Starter. I have tried everything suggested here in order to get better battery life out of Ubuntu, but without success.I'm wondering if I might have better success with another distribution.Are there any Linux distributions available that can claim longer battery life than others, on netbooks and in general? This question can be answered objectively if it is backed up with hard data from based on benchmarks,
View 1 Replies View Relatedi recently purchased my second laptop, primarily for linux. When i chose it, my main concern was battery life. Just to make a side note. When i say battery life, i mean how long the computer takes until the battery goes flat. Not how many years/ect it takes till the battery will no longer hold charge.
My new computer claims to be able to get 10 hours. Although it's a bit off, i get a satisfying little bit over 6 hours, from full charge. This is running Windows 7. I couldn't wait to put Linux on my new computer, i have, but it just isn't satisfying because i only get about 4 hours while running linux, tried three different distros, and all roughly the same.
I am using Ubuntu 10.10 on an IBM ThinkPad t43. I have a 9 volt battery that I use only occasionally. Usually I use the AC connection and when I'm finished working I leave the laptop in "sleep" mode. (Not always, but often.) When using the AC is it okay to leave the battery in the computer or is it better to remove it? Some swear it shortens the battery's life to leave it installed when not in use. Others swear--with equal fervor--that the newer ion batteries know when they are fully charged and don't have to be removed. Which is true? It's inconvenient to keep taking the battery in and out, but if it's necessary to prolong it's life I guess it's worth it. Some clarity good because, as I said, you can find equally impassioned arguments for both sides of this issue.
View 6 Replies View RelatedSo I've come across several tips to optimize battery life on Linux. [URLs]. In addition to undervolting, I would like to underclock. Is there a way to control CPU speed outside of the BIOS via some software control in Linux... or some sort of boot manager? I would like to boot to linux using underclocked speeds and have Windows running full blast. Is there a way to run Linux completely in RAM? I have read that saves on power consumption from the hard drive.
