Debian Hardware :: Thinkpad E440 Does Not Boot Without Battery Plugged In
Jul 3, 2015
I have a thinkpad e440 with Debian Jessie installed. I use GNOME and thus systemd. Recently the laptop's battery stopped charging when the AC is plugged in. This could be several things, maybe I need to get a new battery (the battery is only a year old). However I need a computer for work, so I tried unplugging the battery and turning on the computer with AC plugged in.
The computer turns on, the grub menu appears, but after I choose the option to boot Debian grub shows the loading ramdisk (or is it the kernel or something like that? The two lines that grub shows after selecting Debian) verbose and then shuts off. When I plug the battery back in, grub is able to boot Debian. As my battery is running out I am not sure whether I will be able to boot when the battery life is zero. Is systemd just looking to make sure the battery is plugged in and then fails when it is not? I suppose I'll find out soon as to whether I can boot without battery life, but the battery plugged in.
With 0% battery I am able to boot into Debian as long as both the AC and the battery are plugged in. Battery still won't charge, but at least I can use my computer.

A couple of days ago, my laptop battery starting discharging at random times. I could rectify this by either pushing the A/C cable in or rotating it slightly. Now the battery discharges unless the A/C cable is pushed in constantly. A few months ago I had a similar problem, though it was accompanied by the computer randomly shutting off. The battery had to be removed and reinserted before I could successfully power the machine back on. Purchasing a new A/C cable fixed this problem quite well. I suspect it may be the battery this time. The gnome battery monitor in LMDE is going completely nuts, announcing I have five minutes of power left and then happily informing me that I have 10 hours 42 minutes only a few moments later.

For about the past month I have been having a very frustrating problem When I boot the system with the ethernet cable attached it acts as if the cable is unplugged even though the connection light is litWhen I boot the system with the ethernet cable disconnected and wait until it boots all the way to gnome and then plug in the cable everything works fine

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.

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?

This sounds strange, but my laptop (running 11.2) won't boot correctly unless my external HDD (ext3) is on and plugged in. If I don't turn it on, it hangs at the start of udev. If I press ctrl+c, the system continues to boot, but the keyboard and mouse don't activate... don't function, etc. But I can press my power button and it does shut down. Going through dmesg (during a successful boot with the external HDD on), I saw this (not sure if it is relevant):
Code:
[2.201029] scsi 2:0:0:0: Direct-Access Ext Hard Disk PQ: 0 ANSI: 4
[2.201450] usb-storage: device scan complete
[2.206637] sd 2:0:0:0: [sdb] Spinning up disk......
[6.062434] udev: starting version 146
[6.225262] .
The device sdb1 is the HDD.
Now, I don't know much about udev. I can tell you that I have no sdb1 lines in /etc/fstab, and I have no autofs references to it.

I was building LFS on a pendrive this morning when it crashed in the middle of making gcc. I rebooted without my pendrive and I never got into the desktop. Instead, I get a visually pleasing terminal telling me that it couldn't find and that the only way to reboot would be to press CTRL+D. I'm then given a command line and that's that.
Rebooting with the key inside works perfectly.
I reformatted my key and now there's nothing on it. I feel like somewhere somehow I added an entry to the boot process of my system and now I have to remove it. Never dealt with something like this before
Fstab:
/dev/disk/by-id/ata-WDC_WD2500AAJS-60Z0A0_WD-WCAV2M336077-part1 swap swap defaults 0 0
/dev/disk/by-id/ata-WDC_WD2500AAJS-60Z0A0_WD-WCAV2M336077-part2 ext4 acl,user_xattr 1 1
[Code]....
The LaCie entry at the bottom there is my pendrive.

So I just got a new 1gig HDD and added it to my ubuntu server but if the HDD is plugged in when the computer is off, it will not boot. But if I turn it on and then plug it in, everything is fine.
I dont know whats happening when it tries too, there is no monitor. What logs should I check and what should I look for?

whenever Ubuntu boots, it searches for an external hard drive that I no longer have plugged in. It hangs on the Ubuntu load screen for a while, then says that it cannot find the drive and I have to press (S) to skip the attempt.

After I select to boot Ubuntu (I dual boot Vista Ultimate 64.), it just sits at a black screen with the blinking dash.Cannot enter anything and it will just sit there. But if I plug in my Flash Drive it will boot into Ubuntu either before starting the computer or while Im stuck in the black screen.Plugging in the drive while I am in the black screen will make it boot right up. The drive will light up and a couple lines that quickly say something will show up on the screen and then it boots.This Flash Drive contains Ubuntu and is what I used to Install Ubuntu.

I decided to test Ubuntu 11.04 on my Lenovo Thinkpad T520 as it has no OS currently. I created USB boot media with unetbootin on a 4 Gb stick, and it worked with my old T60 but not with this T520 (it just jumps back to boot device selection few seconds after selecting USB as there was nothing written on the stick).
Specs of the machines are
T60:
C2D T5400 CPU
3 Gb RAM
ATI Mobility Radeon X1400 GPU

I have connected (sata cable I mean) the drive where I have got my Ubuntu installation to another pc with windows 7 64 bits (but I think that 32 and 64 doesn't make difference). Windows 7 doesn't boot. So I thought it may be some kind of issue with the hard drive itself (but the drive is healthy), anyway I have plugged one drive from one NAS (you know, NAS drives are linux partitioned and formatted).Same result: windows 7 doesn't boot.
Windows 7 boot sequence hangs and at the next boot prompts
"Repair windows installation"
"Boot windows normally"
(and obviously none of the options works)
Looks really like that Windows 7 doesn't boot if any linux partitioned and formatted drive is present.

I have a system I use as a file server running Ubuntu 10.04. I don't have a screen hooked up to this system. When this system reboots, if there is no screen, X wont start on it. This then prevents me from using VNC to get to the desktop.If a monitor is plugged in at the time it boots, then everything works, and I can then remove the monitor. But moving this monitor between computers and crawling under desks is not enjoyable.How can I fix this so X starts on boot even when no monitor is plugged in?The error I get in /var/log/Xorg.log* looks like this:
grep -EnC2 "EE|WW|fatal|error" /var/log/Xorg.0.log

I use an IBM Thinkpad T30 with an ATI Radeon Mobility 7500 graphics card as my work machine, mostly at a desk, using a docking station to link it into a monitor. I upgraded to Lucid last weekend. When using the integral screen on the laptop the graphics have been fine, but when using a monitor I initially got some very poor contrast, brightness and gamma output, described in this bug.
https://bugs.launchpad.net/ubuntu/lu...ux/+bug/548709
According to the advice in that bug report, I upgraded the kernel, with Kernelcheck automatically updating me to 2.6.35-candela. Now, rather than poor graphics with the monitor it just hangs on the splash screen, displaying the words Ubuntu with the dots underneath.
Reading around, when similar problems have been seen in previous versions of Ubuntu it has been a graphics issue, which fits. One piece of advice I've seen quite commonly is to remove the "quiet splash" from grub, which I've tried but doesn't work. I am tempted to try and work through the different grub commands these guys used to tackle a similar problem with the live CD:
http://ubuntuforums.org/showthread.php?t=1472054
But am a bit reticent as I don't know what they all do.
As an aside, the 2.6.35-candela kernel brings up a bunch of errors on boot, described at the link below, but reading that thread they don't look like they would cause my problem:

I have an old computer (Pentium 4) without a monitor. To make the most of it I installed Ubuntu server on it and have been using it for almost a year. A couple of months ago I don't really recall what I did but since then it doesn't start-up unless a monitor was plugged in.
I've tried pinging it but it doesn't respond when no monitor is plugged in. meaning it's not even booting correctly.
I'd like to know what the problem is and how to fix it. And I'd really appreciate any help in diagnosing the problem. I just don't know where to start.

I was wondering if anyone uses older laptops (for e.g., Centrino M) like Thinkpads from the T40-series.I am finding LXDE to be extremely buggy. There's been more than one occasion in which I've been totally surprised at weird 'events.' It's been so often that it annoys me now and I wish to switch DEs now.
I guess my choices are Gnome, KDE and xfce. I think KDE 4 will be too bloated so I guess that leaves Gnome and xfce. I also read that LXDE is actually a 'beta' (release?) even though LXDE versions are in 'release' form. I come across too many 'bugs' so I think the other desktops, even if it takes up a bit more resources, is a compromise I have to take.
Is xfce the best choice for an older laptop like mine? I thought LXDE sounded great and had great potential but the amount of bugs I find and the fact it looks like there's not much of a team developing and working on it, is disconcerting. Hopefully, things will improve but I don't want to work out or encounter 'bugs' on my laptop so often.

I am reciving a strange backtrace furing the boot process of an IBM thinkpad 600 with debian lenny. The errors appear to be in the 'cs' module, but I'm not sure. Also the "Waiting for /dev to be fully populated..." script in which the backtrace occours also hangs and hasto be Control-C'd, or you have to wait for it to time out. Attached is my syslog

I have an old laptop I bought for $20 & thought I'd install Linux & XP in a dual-boot. It couldn't handle the MINT installer, so I thought I'd go with Debian. XP was already on there, so I ran the Debian install CD (LXDE), set up the 2nd partition, and finished installation. It rebooted once, but since then will not load Debian.
I get the GRUB menu, pick the default (not single user), it runs through all the lines of text down to the block that says "starting gnome display manager gdm" & maybe 4 lines after that (which I can't read in time)... then the screen goes blank, there's a brief flicker, the CPU thinks a bunch, and then there's usually a low-pitched BOOP at which point the CPU stops thinking & the screen just stays blank. The power is still on, but nothing happens.
Anyway, I don't know if it has an ATI card or whatever (saw something online alluding to that being a problem.) I also don't know how to use the single user mode, or how to display error messages, or do anything useful in the command line. Haha... But I'm a novice programmer & "computer literate" outside of Linux, so I can learn.
The laptop has 128MB of memory (which functions perfectly according to MemTest 86), I think a 450MHz PIII processor, 20GB HD (split between XP and Linux), a dead battery, a slightly damaged Power Supply, damaged screen...

with the help of others (to whom grateful thanks), I've managed to get this distro installed and my PCMCIA Wireless card working without a LAN connection!Result......well it was for me!next big prob is sound.......any sound at all!This command sudo modprobe snd-cs4236 sometimes gives me some, just for the current session, if it don't want to play, it just ignores me!Two main questions,
1) How do I get the attention of the "Alsa Mixer"? (the GUI is normally just blank and may or may not be activated by the above command!)
2) Once I have the attention of the "Alsa mixer", how do I maintain it upon re-boot?
Some one guided me to this post and despite it's age, I appended my plea for help....but I fear it is not the correct place............I just hope I'm now in the right place.url

I've just joined the linux gang(or I am trying to) I have
-downloaded desktop/netbook edtion
-burned to dvd using infrarecord
-changed bios settings to boot from cd
-didn't work
-used the override feature that gives a bootlist at splash screen but cd drive not listed so I assume the cd is not recognised as a boot disk
-tried the usb/cd maker that comes with in the rar but its looking for the cd image...an .iso file, but I can't find one in folder.
ubuntu says I can run a trial from the cd alongside vista but when I open the executable it just offers intall, no try and if selected starts to install I think I can do the partition thing if I have to but I don't want any vista running on my machine.

I am trying to build a media pc, and successfully so till this one little/big problem. I want to be able to turn on my tv, and pc, and have the pc display onto the TV. Ports used are HDMI(pc)->HDMI(HDTV)
But for some reason Ubuntu will not fully load with just the TV plugged in (all i get is a black screen, not even a "no signal" message).Once a LCD monitor is plugged into the VGA port. Then I see a glossy white Ubuntu symbol on the LCD monitor. Then the Ubuntu loading screen appears on both the LCD monitor AND the TV. in mirror mode. And I can see the desktop on both monitor AND TV.
I am using an ATI RAEDON HD 4200 chipset that is on the mobo. I have downloaded the proprietary drivers and installed them. A few things I have tried are the instructions on this page, finding my modeline using a modeline calculator and also going off of a suggestion from a thread on this website, stripping down my xorg file so that the Xserver would autodetect it. Which i think I did wrong because after that, it wouldn't display on TV at all.

If I boot CentOS (5, up to date) without my USB headphones are plugged in, all sound output goes to the sound card. But if I have the headphones plugged in when I boot, all output goes to them, and the sound card does not seem to be recognised at all.
Is there any way I can force the sound card to be recognised, and chosen as the default device, when booting with the headphones plugged in? If I have booted with the headphones plugged in, and then I unplug them, go into System|Preferences|Sound, and press the Test button with sound playback set to autodetect, I get a dialog with the message: audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! gconfaudiosink: Could not open audio device for playback.
Then I started System|Administration|Soundcard detection, and it detected both Intel and Radeon sound cards, but its test button did not produce any sound for either. I moved the Intel device to the top of the list in the Settings tab, and then ran "Reload audio drivers" in the System tab. I got an error message saying I needed to reboot, but I didn't. At this point, the test buttons in the Sound test tab, and in System|Preferences|Sound started working OK. Do I have to go through this rigmarole every time I boot with the headphones plugged in?

So I think it's a problem with the resolution not changing back. But I don't see any menu, like the HP Logo, on my monitor at all. Thought It might be the blue cable, changed it, nothing. Plugged it back into TV and it works fine.
