Debian Hardware :: Hibernate Fails When On Battery Power

Jan 31, 2011

Fresh new installation of squeeze on an MSI Wind U100 netbook.Everything works fine, except resuming from hibernate when on battery power. The netbook starts loading the hibernate info after grub booting, then the screen goes blank and the netbook reboots.The unusual thing is that resuming from hibernate works when on AC power.Could not find anything interesting in /var/log/messages

Debian :: Battery Discharging Even When Power Is Connected - Asus UX305

Feb 26, 2016

I'm using debian testing on my Asus UX305. When my laptop is connected to power, the power notification still shows "discharging". And The battery part of the laptop feels unusually hot.

while connected to power, "acpi -b" gives me this information: Battery 0: Discharging, 98%, discharging at zero rate - will never fully discharge.

This problem was reported by some ubuntu users too: [URL] ....

Debian :: Allowing Disk Check To Proceed When Running On Battery Power

Feb 12, 2011

Is there any way to allow normal fsck boot-time checks when running on battery power? After looking around, the only solution I've seen is to manually alter the /etc/init.d/ and /etc/init.d/ files and remove the AC power check. There must be a better way than that surely?

Debian Configuration :: Squeeze: Suspend/hibernate Resume Fails With Radeon Graphics

Aug 6, 2010

I am running Squeeze on an older Compaq EVO laptop with radeon graphics.

A few months ago, after an upgrade, suspend and hibernate stopped working. The suspend or hibernate worked fine, but the resume just hung with a black screen. I finally got around to looking into it and found a workaround.

The workaround is to disable Kernel Mode Setting for the radeon. This can be done by adding the boot parameter "radeon.modeset=0" or by editing /etc/modprobe.d/radeon-kms.conf so that it includes the line "options radeon modeset=0".

If you are interested in the details, you can search for problem reports related to radeon kernel mode setting.

Debian Configuration :: Restore From Hibernate Fails From Time To Time?

Apr 28, 2011

I have a Insprion 14R (N4010) and when I hibernate it will usually restore without a problem, but maybe 15% of the time it will reboot while loading. I would like to figure why, since I'd rather not lose anything... My swap space is 5.9GB, I have 4GB RAM (video uses 1gb, so I have 3gb usable)

lspci says

00:00.0 Host bridge: Intel Corporation Core Processor DRAM Controller (rev 18)
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 18)
00:16.0 Communication controller: Intel Corporation 5 Series/3400 Series Chipset HECI Controller (rev 06)


I do have the hibernate package installed...

Ubuntu :: Prevent Automatic Shutdown/hibernate/sleep When Critical Battery Reached ?

Aug 8, 2010

I'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

Ubuntu :: Hibernate Will Not Power Off System

May 6, 2011

I've got a problem with hibernating my laptop. It manages to copy everything to swap memory, but when it finishes, it won't power off my laptop. I have to manually turn it off (by pressing the power button for a few seconds). If I restart, everything is still there, so the hibernating itself works, but not the powering off part. My laptop is an Asus notebook K52F with Ubuntu 11.04 and Gnome 3.

Fedora :: Battery Power Comes Down To 40 - 41 Percent

Mar 18, 2010

I am using Fedora 12. Prior to this I was using Ubuntu 9.10. In Fedora 12, I am facing a problem with battery power. Sometimes when it is fully charged I remove the power cord, battery power comes down to 40%-41%. It never happened with Ubuntu, which gave quite a good battery performance. My question is when it is showing Laptop Battery 100% i.e. fully charged, if I remove the cord why it comes down to 40%-41% (and always in this range).

Ubuntu :: How Do I Check Battery Power

Dec 17, 2010

I have a starling netbook, but I have the regular ubuntu interface on it. I normally have it plugged into a power source, but now it is unplugged. As I remember, at one time there was an icon on the top bar that showed you how much battery life you have left, but now I don't see it. How do I get info on the percent of power I have left?

Ubuntu :: Battery Power Percentage To Low

Jan 19, 2011

I know how to set and have set my net-book gz5 running on lucid to stay on at all times.however unlike in xubuntu I don't have the option to change when the computer is critically low. I don't have the room to install xubuntu with my preferred gnome desktop wondered if anyone out thee knows where if there is a .config file that I can dictate the percentage of battery life before being considered critically low. ei now it seems to consider itself low at 15% which robs me of about 2 hours of usage id like to set it around 1%

Ubuntu :: Hangs And Freezes On Battery Power?

May 30, 2011

I'm running 11.04 on my Dell SXPS 1645. Today I unplugged my laptop from AC power a few times and after about 10 minutes, Ubuntu would hang, not responding to anything. Frozen mouse, frozen keys. The ONLY thing I could do to get it out was to do a hard hardware restart by holding down the power button.

It happened twice on Skype (and I thought it was just the buggy 2.2 beta that was hanging my beautiful OS), once while installing a printer, and once while I was just futzin around on firefox.

General :: Laptop Freezes When On Battery Power

Jun 1, 2011

I'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):

Slackware :: HD Constantly Spinning When On Battery Power

Dec 27, 2010

I'm running the latest slackware64-current on my Dell laptop (Inspiron 1420). I rarely run it on battery power, so I don't know when this behavior started, but now it seems when I'm on battery power the hard drive likes to spin down and then spin up. This is not after 5 minutes or so of inactivity. This is 30 seconds of inactivity because I'm reading a web page or something. There is a noticable delay in the response of the system as a whole when the drive is having to spin back up. I'm also using xfce-4.6.2 with the xfce power manager. I've checked the settings, and I don't see anything about spinning down the hard drives. I've also looked through some ACPI rules, but I'm coming up empty.

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 reactionsŁ 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 MaintenanceŁ 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 :: Hibernate Option Disappears From Power Down Menu

Mar 9, 2011

I increasingly use Ubuntu so swapped SATA ports 1&2 around so now 7 boots from BIOS F11 pop out menu. Windows did not complain so far but hibernate is missing from Ubuntu's power down options. I installed Ubuntu Tweak, but cannot see an option to re-enable. Is this something to do with the swapped HDDs &/or the swap partition? Or more likely a recent update?

OpenSUSE Hardware :: 11.2 Virtually Unusable On Battery Power

Mar 23, 2010

I recently bought a 12-cell (extended-life) battery for my HP dv8000 AMD Turion64 laptop. While the extra battery life is spectacular, the machine is virtually unusable when not plugged in. Either the hardware or the OS (I'm not sure which) seems to view each of the 12 cells as a separate battery, so whenever a cell nears depletion and the machine prepares to transition to the next cell, the computer slows to a standstill, as though it were shifting into an extreme version of Powersave mode. This can last for several minutes at a time, during which period all I can do is stare helplessly at my screen.

I have all but disabled Powersave features in the Power Management applet, setting the laptop to Performance mode on both AC and battery power, with Powersave only kicking in below 10%. So that isn't the source of the problem. I have also disabled Compositing and all desktop effects, except the mouse pointer application-icon animations that appear when I open an application, which I can't figure out how to disable. All this to no avail.

Plug the machine back in and it zips along at a merry Linux pace. I don't want to keep it plugged in all the time, though, because a) this is a laptop and therefore should be mobile; and b) keeping a charged battery plugged in drastically shortens its battery life. Besides, this is a brand-new battery; it should still be working fine.

I am having several problems with what i believe to be gnome-power-management. Power management will randomly say that either i do, or don't have a battery. This means that the icon in the notification area does not appear, and I can not access the settings for on battery power. also, when i tell Ubuntu to suspend, it just goes to the screensaver and nothing happens. conky is still able to read the battery just fine, its power management thats having problems.

Ubuntu :: Huge Performance Decrease On Battery Power

Oct 23, 2010

I'm having a huge performance decrease when I'm on Battery Power. Plugged in this thing runs AMAZING, HDMI with HD video, I can run compiz 3d, full desktop advanced effects, HD video from ....., you name it. Just when I pull the cable out it slows down. I tried disabling ATI powerplay but that didnt help.

Is there a way I can toggle the performance, so that I can get "plugged in level performance" even when i'm on battery power? I'm not too bothered about how long the battery lasts. I'm usually always near an outlet.
