Ubuntu :: How Much Battery Time Still Remains

Dec 5, 2010

When I boot without the AC cable plugged in the Power Applet says I am on AC power (but the notebook is of course running on battery power). Which is bad because I don't know how much battery time still remains. Strangely, when I boot on AC Power and then remove the AC cable both the fact that battery power is used and the remaining battery time is shown correctly. Also when I boot into battery power and then plug in the AC cable it correctly shows that the battery is charging and how long it takes until fully charged. I use Ubuntu 10.10, 32bit on an Acer Aspire One 751 if that helps. The problem has also existed in Ubuntu 10.04 and I hoped the update would solve it but it did not.

General :: Swap Usage Remains Zero All The Time

May 31, 2011

No matter what I do, the SWAP usage remains zero all the time. Is there anything I am missing? In the following case (see attached screenshot) I am running make on the kernel that I downloaded. The CPU usage is understandable. But what is the use of Swap when its never used. [URL]. I am on Kubuntu natty. My partitions are as follows:

Kamesh@Galaxy:~$ sudo fdisk -l

Ubuntu :: Battery Meter Never Accurate As Far As Time Remaining Goes

May 2, 2010

I have an Asus EEE PC900. Just installed 10.04 netbook remix and everything works fine straight out of the box. it works great and is a vast improvement on windows xp which was previously installed on the asus. Just one small thing - the battery meter is never accurate as far as time remaining goes - it currently says i have 19 hours 55 minutes to go - unfortunately this is not quite true i suspect. It was the same with 9.10, Does anyone have a solution for this?

Ubuntu Installation :: 64bit Less Battery Time Than 32bit

May 13, 2010

I installed Ubuntu Lucid 64 bits, but found out that my laptop battery doesn't less longer on the 64 bits. I never had this problem with the 32 bits version. After going back to 32 bits lucid my Battery had much more time. My question is why are the 64 bits eats more battery energy than 32 bits version?

Ubuntu :: Time And Date / Battery Indicator Not Working Properly

Oct 19, 2010

The Time and Date at the top docking bar is Hanged. It shows Mon, Oct 18, 6:35 PM. That's all. But when I click on it, it shows correct date in Calender. And correct time in the bottom. I believe those gadgets are not updating at all. Cause my Battery indicator is also not working.

Ubuntu :: Battery Backing CMOS Memory Dead - RTC Time Setup

Mar 9, 2011

In my computer with Ubuntu 9.10 the battery backing CMOS memory is dead (and replacing it is not an option). This requires from me to set up RTC time in BIOS each time I turn on computer (default date is from couple years back). When I don't set time, Ubuntu don't want to startup and it shows me fallowing message :

/dev/sdb1 : Superblock last mount time (Tue .... 2011, now = Mon ...200 is in the future.
/dev/sdb1 : UNEXPECTED INCONSISTENCY; RUN fsck Manually.
mountall: fsck / [842] terminated with status 4
mountall: Filesystem has errors: /
init: mount main process (840) terminated with status 3
Mount of filesystem failed.
A maintenance shell will now be started.

Is there any way to run Ubuntu without having RTC time set over, and over again in BIOS ? (It's acceptable for me not to have current time).

Ubuntu :: Laptop With No Battery - Checking Battery State

May 1, 2010

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?

Debian Hardware :: Lower Laptop Battery Charging State To Prolong Battery Life

Mar 2, 2010

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.

Ubuntu :: "Battery May Be Broken" - Disable The Popup If Battery Has Little Life Left In It?

Aug 31, 2010

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.

Ubuntu :: Install Remains On Startup Screen

Sep 7, 2010

I installed ubuntu via virtualbox one day for fun, just to test it out. I didn't really need it, so i deleted the partition it was on and resized my hard drive. Thing is, when i startup my computer, ubuntu is still listed as an operating system, but whenever i go to choose it, my computer says "this file is missing or corrupt." I was just wondering if i make it so Ubuntu is not even shown on the screen anymore.

Ubuntu Installation :: Removed - But Option Remains On Boot Up

Jun 19, 2011

I reclaimed the hard drive space on my hard drive entirely for Windows 7 with the intention of installing another hard drive solely for Ubuntu. When I reboot my computer it still gives me the option to choose Windows or Ubuntu. I tried Ubuntu just to see what happens and all that came up was some error and an option to type in help for a list of commands. And if it makes a difference I was running Ubuntu 11.04.

Debian :: Printer Remains Idle?

May 17, 2011

This is my first day with Debian, I have used other distros, and am a long time linux user. My HP D 1600 series is recognized, but when I try to print a test msg. it says sent, but the printer remains idle. I have tried everything I know. When I run the trouble shooter I get this. /// /usr/lib/cups/backend/hp failed////

In the past when having a printer problem I have installed HPLIP-gui and removed the printer then re-installed it. That has not worked and I cannot even remove the printer.

Debian :: System Remains Sluggish After Heavy CPU Use

Jun 11, 2011

I have a problem with my Debian squeeze system. After I have run some CPU-intensive application for a while the system becomes sluggish. Ok, maybe one would expect that. But. The system remains sluggish even after that process has been killed and then top shows high cpu usage from unrelated processes and a high %sy percentage as well. I don't really know where to begin solving this problem except I've checked that this is specifically related to (at least) CPU use as opposed to heavy memory use or IO (by running an application with low mem/no io but high cpu use). I am running the latest standard kernel from squeeze, 2.6.32-5-686. Also, thing is, I remember having similar problems with other Linux distros before, where for example gzipping a large file would cause the same. I did not have similar problems on {Net,Open}BSD, so a hardware fault seems an unlikely reason to me.

Hardware :: Boot - Down Button Remains Pressed ?

Sep 13, 2010

When I boot, apparently any Linux (Ubuntu and CloneZilla), I see the letters Code: ^]]B scroll pass, over and over again. This represents the down key as when I try to do anything the down key is held down. This occurs during boot on Ubuntu (once I get to the login screen it stops and does not happen). This does not happen at the GRUB screen or in Windows. It also occurs during the entire CloneZilla process and Ubuntu alternative install process (making both of these impossible)

I can't find any reason for this to happen and have been using both CloneZilla and Ubuntu for a long time before this happened. Does anyone know what I could try to fix this.

Ubuntu no longer boots.

Ubuntu Networking :: (fluxbuntu) Network Remains Connected; Internet Connection Sometimes Not Available?

Apr 10, 2010

I'm running Ubuntu 9.10 with fluxbox installed. Occasionally my internet connection will stop working, but when I check on wifi radar, I'm still connected to the network. The router is not plugged into a computer at the moment, just the cable jack. It is likely a hardware problem however, since my other laptops also experience disconnects. Any help beyond "change the cable" would be greatly appreciated. For instance, even though I am connected to the network, I cannot post at the moment due to lack of internet connection.

I tried using the nvidia settings application but to no avail.

Ubuntu Networking :: Mobile Broadband Keeps Disconnecting, Network Manager Remains Silent?

Apr 18, 2010

I have a broadband mobile modem iCon 225 (Option) with SiMobil provider (Slovenia). I run ubuntu 9.10 (Karmic Koala). I connect to the internet without problem. After a few minutes, the modem lights start signaling that there is no connection, but the network manager shows connected status. I have to reconnect the network manager to regain connection. After about a dozen times of reconnecting like this, I have to reboot the system, as it won't connect, even if I unplug and replug the modem.

I've noticed these frequent disconnects have started a few days ago. I did experience disconnects in the past, but as nearly often as this. I can't attribute disconnects to activity/inactivity, as they seem to happen no matter what I do.
