Ubuntu :: Computer Turns On Then Off Then On By Itself
Jul 6, 2010
my computer this morning, then it suddenly turns off. I press the power button and nothing happens. After a minute I press it again and it turns on, but it quickly shuts down when it hit the boot screen. After I tried turning it on again, but it turns on for about 2 seconds and quickly dies. Some times it turns on itself and then turns back off. This happened when I had WIN XP installed too (which was about 2 years ago). I run full Ubuntu 9.1, no double boot. Is this hardware problem or a virus that affects both Windows and Linux? :O

suspend has always worked fine with 11.04 and now it stopped working a few days ago. How can I figure out what is going on? The display turns off but the computer never turns off and the only way to bring it back is to hold the power button down and then start it back up.

I have an 9.04 installation of Ubuntu.After a classical system update via the GNome-GUI my computer (laptop ASUS PRO55series) got the sick habit to turn off abruptly during work.It's like if there were no electricity in my house.It is not the hardware since I also have windows vista and it works fine.I suppose this is from ubuntu; it could be from the heat regulation, that ubuntu thinks it is too hot inthere and just turns off the laptop.

I just installed Ubuntu 10.10 32 bit on my desktop and I've encountered a curious and somewhat frustrating issue. It appears that when I plug a flash drive, external hard drive or MP3 player into a USB port my computer turns off. Sometimes it happens instantly, other times it occurs a minute or two later when I'm transferring files. I'm not sure how to approach this issue. I've searched the forum and haven't found any mention of this. I am working on said desktop and all other hardware seems in good working order. If it helps, This is a 3 year old desktop with an AMD Athlon 64 X2 4600 cpu, a ABIT NF-M2S AM2 NVIDIA GeForce 6100 motherboard, an EVGA GeForce 7600GT video card and a SATA harddrive. I can post a log if someone wants, not sure which one to post though.

I have an Asus Eee S101 netbook running UNE 10.10. When I have the netbook on, I have no problems connecting to my WPA encrypted wireless network being broadcast by a Buffalo router running DD-WRT. When I turn on my desktop computer in the other room (running Windows Vista) which also uses the same wireless network, the netbook disconnects. Then it will take a few minutes to reconnect. Periodically it will do this until the other computer is powered down. I don't know if this is an OS issue or the hardware, but is there any sort of troubleshooting I could do to look into this? It seems like the desktop is somehow interfering with the netbook's connection, booting it offline.

I have 2 computers, one running Ubuntu 9.10. I don't often use this one and rather than turning on the power point & having the computer automatically comen, as my Windows machine does, you had to press the power button to switch it on.As of yesterday - after not using it for some time - it turned itself on when I turned the main power point at the wall on to use my other computer. Thought maybe the button was knocked, but this has happened twice since. Seems it's mysteriously changed to automatic start up I can't work out how to change this. Can someone tell me what settings need to bechanged to have it not turn itself on until asked, please?

My laptop will be fine, then it turns off then immediately boots itself to a blank screen and no hard drive activity. This has happened 3 times today and never before. what ive done so far The first time this happened i tried turning it off and back on, still no screen and no hard drive activity so i took one of the RAM sticks out. Booted fine... To confirm that the RAM was bad i put it back and tried booting again, unfortunately it booted fine... i thought it was a fluke.
Until his happened a second time and instead of taking the RAM out, i waited a half hour and rebooted and it started booting fine, i turned my back for a sec and it was dead again. I have taken that RAM module out and am hoping it will not happen again, but it could well be the other RAM module since i really don't know or even if it is RAM at all.
Question is. Is this a RAM issue or something else? Where can i find a log to see what happened immediately prior to it offing itself? What's the chances it's the heatsync? (the laptop doesn't feel as hot as it sometimes does)

I had Ubuntu installed on my old laptop in dualboot with windows. This year i bought a new Sony Vaio VPCS12M9E preinstalled with windows 7 pro, but i liked the idea of having the opportunity of chosing between windows and ubuntu, so i downloaded ubuntu 10.10 and burned the ISO-image to a disc, and restarted my laptop just as i did when i installed it on my old laptop. The problem is that when i boot the disc after restarting the computer, the screen just turns black. What can i do to install Ubuntu?

I've read many posts about other people having this issue and I can't seem to find one that is the same problem I am having. I'm totally new to ubuntu and linux as well for that matter, Basically I wanted to give linux a try and started doing some research and liked everything I read about ubuntu. I went to the website and used the wubi (I think that was what it was called) to install ubuntu. Now when I boot my computer it asks me which operating system I would like to use. I navigate to ubuntu and press enter and it starts up with no problems what so ever.
At first I was really surprised with how easy the installation was and how great everything was going, however. After looking around for about 10 minutes, the screen abruptly went black and then my monitor had a small blue box on it with "No input" on it before the light went from blue to orange. I tried hitting every combination of keys I could think of and in the end had to do a hard restart.
Long story short. every time I use ubuntu my monitor shuts off after about 10-20 minutes, regardless of what activity I am doing. I've tried going to /apps/gnome-power-manager/timeout/ to make sure that sleep_display_ac was set to 0 (it was), I've turned off power management using the power manger under preferences. No matter what I have tried, it continues to be a problem.

Since I had updated to Lucid, I'm having some trouble with running my laptop on battery. It usually turns off when the battery notifier is still at 13%~18% (it is not shutting down, it is like when your battery runs out of energy). First I had thought that was a problem with the notifier and I was missing when the battery had no charge, but I kept looking at the notifier and suddenly when it had reached 15% my laptop just went down, without saving any job.
I've just upgraded to Lucid Lynx, running on a HP Pavilion dv4-1123us with 2.00 GHz Intel Core2 Duo T5800, 4GB RAM.
The battery is a 6-cell Lithium-Ion that came with the laptop.
I'd bought it about 1 year ago.

I have been using ubuntu for the last year. Everything has been working fine. One day I was in class listening to music through my headsets and closed the lid. The computer suspended and I didn't think anything about it. When I got home and opened the computer up with the headsets unplugged, the speakers were not playing. Now I only get audio through my headsets, but if I suspend the computer with the headsets plugged in and open the computer up with the headset unplugged, the speakers plays for 5 seconds and then turns off. I have an HP Pavilion Entertainment PC with Altec Lansing speakers

So I have this laptop, and ever since updating to Ubuntu 11.04, the screen will freeze when it turns off to save power, especially if music or video are playing. The screen picture will come up, and the mouse even moves, but I am unable to manipulate anything else on the screen. Sometimes I can hit buttons in the active program, but I cannot see that they are hit. However, when it's a music program or a video, I can hear the sound stop if I hit the pause button. I cannot use the power button to turn it off at this point. I am to do a forced hardware shutdown.
I recently downloaded the a for-pay game, Steel Storm: Burning Retribution, and it also seems to be affected by this bug when it tries to take over the screen. I have managed to close the program by intuition and following sounds, at which point the screen is restored to it's normal settings, but it is frozen and I have to do a forced shutdown. I downloaded several other games to test this out, and many of them then resize the screen have the same problem, though some of them occasionally work and occasionally do not. Of course, the only game that I actually paid for never works.

I am running Fedora 13 at the moment and am having trouble with my internet connection. The connection works fine, but at some point during the night, it turns itself off. When I try to get back on in the morning, I have to sudo ifup eth0 to get it working again. I tried a small bash script running through cron to do this for me every hour, but that doesn't seem to fix the problem.

I have a problem with opening files with accents with the kate editor. They are html files written on Windows, and contain the line
HTML Code:
<META HTTP-EQUIV="Content-type" CONTENT="text/html; CHARSET=Windows-1252">
Opening in kate, no matter the encoding, messes up the characters. They turn to (a '?' in a hexagone) or chinese characters!What's the proper procedure to open and save those files properly in kate ?

My webcam LED turns on whenever my Asus P50IJ laptop wakes up from sleep or suspend, and subsequently will not turn off. I can't tell if my webcam is actually activated or not, and furthermore the light beams right into my eyes and makes my lappy not so usable.
If someone knows why this might be happening or could possibly help me fix it that would be very much appreciated. I'm really trying hard to stick with Linux, but little things like this are making it difficult. I'm kind of a noob, but I'm trying so please be nice.

I use ubuntu netbook for an eee pc 1000h because windows is underpowered. I got it working perfectly in 10.04. I upgraded to 10.10 thinking, if they got it right with 10.04 then surely 10.10 should be fine. All function keys except wireless work.
1. After sleep, wireless turns off. Have to restart and re-enable in bios.
2. If I disable and the re-enable wireless networking it tries to connect but never does resulting in a reboot needed. Checking bios wireless is enabled and connects perfectly on reboot.
Just don't close the lid and sleep because you need a restart. Why would 10.04 be easy and the new version fail? I am windows user and linux does not do this kind of thing normally. MS screws things up with upgrades not linux surely.

I have fresh installation of Ubuntu server upgraded with apt-get dist-upgrade and with XFCE4 installed on my notebook. The problem is whenever I type startxfc, startx or X, the NTB freezes, CRT display connected to docking station/port replicator turns off, LCD in NTB gets black. The system does not respong to any signal, even the alt+sysrq ones. If I even install Xubuntu-desktop, as the X gets loaded every start, system everytime hangs after few seconds and I cannot do anything. Now I reinstalled and tried autoconfiguration with Xorg -configure. If I start the X with this configuration file, the result is still the same. Log at /var/log/X11/ seems to be blank.
Any ideas? Should i try to get drivers for my video card? I thought this is not necessary, the X server should start without anything, even only with basic resolution settings. As I looked, the video card chipset (Intel 82852/82855) is detected in my /root/xorg.conf.new file.

I downloaded the ubuntu Desktop i3386 iso and followed the instructions to install from windows. I'm a windows 7 user. So after rebooting, I booted using ubuntu and as it was loading, I left my laptop idle for a few minutes and it suddenly booted windows 7. I restarted and booted ubuntu only to find that it has become command prompt format instead of the usual gui. Then when I tried to use it, it turns to blackscreen and the only thing that produces a response is by hitting the power. It then warns me that the power button has been pressed. The model of my loptop is Toshiba Satellite L640.It says it has security error. Will post later the details of the error.

I believe it might have to do with dpms (according to KiPi on the #debian-boot chatroom) but I'm not entirely sure why my monitors keep turning off 10 minutes into the installation. I have tried using Live CD and a netinst version of the Debian 8.2 installation methods.
I'm going to try to disable dpms in the Live CD and hopefully that works.

While using FireFox the application will sometimes turn a shade of grey. Almost as if the entire application is locked. Most times if I wait for a while it will "colorize" itself after a moment or two and I'm right back to doing whatever I was doing.,I was just wondering if anybody could tell me why this happens?
I have noticed that the AutoTen program does the same thing while an application is being installed. The terminal-style window will open and start doing all the important stuff, and the GUI will grey out until it's done... I just don't understand why FireFox would be doing this...

FC13. In Screensaver, I've made sure no screensaver is selected. In Power Management, PowerDevil is unchecked, profile is set to "performance" and that profile is set to never dim the screen. In fact, just to be sure, I edited all the other unselected profiles to not dim the screen. I've done this as a user, and I've done this as root. My monitor still gets turned off at the 10 minutes mark (I used a stopwatch).
Site search only turned up this thread, but I'm using kde not gnome, and I can't locate a screensaver daemon to kill.

I'm running 9.10 on an HP d530 SFF, Pentium 4 2.8GHz HT w/800MHz FSB and 512KB L2, 1.25GB DDR333 RAM, GeForce 440MX. In the BIOS I have ACPI S3 Video REPOST enabled, as well as ACPI S3 Hard Disk Reset enabled. Resuming had the same problem with either of these settings disabled as well. Install graphics driver is nvidia-glx-96, version 96.43.13-0. To my knowledge, this is the newest driver that supports the GeForce 440MX -- I attempted to upgrade to newer drivers for XBMC before but they do not support the card.
uname -a output:
Linux fahrenheit 2.6.31-20-generic #57-Ubuntu SMP Mon Feb 8 09:05:19 UTC 2010 i686 GNU/Linux
When I attempt to suspend this machine it suspends fine, and will come back to life when I press the power button. I then get a hardware (text mode) cursor for a few seconds, then the screen blanks and goes black. At this point I can ssh into the machine and it is responsive, mostly, but Xorg is taking up 100% CPU and the fan spools up to maximum. The Xorg process is unkillable -- kill -9 won't do it. Load avg on the machine is high and it gets freeze-y for a few seconds at a time. How to get either suspend or hibernate working. This is a media box and we'd like the convenience of a quick resume time, but the ability to save electricity when it is not in use.

I insert my DVD into my machine. The little "waddya wanna do" window then opens, and I select "play in VLC." I then press the play option on the video menu (not the play button on the VLC controls). Then the VLC window turns black, or the part where the video is supposed to appear does, anyway. So double-clicking to get to fullscreen sometimes fixes the problem, but then I can only view it in fullscreen, not good. It didn't fix the problem this time, so I double-clicked again to get out of fullscreen. Then my whole display turns black and white. WTH? The display problem fixes on a reboot.
This happens on a regular basis when I try to play movies. My display is, right now, black and white. After I finish this post I'll restart my computer to fix the colors.Also, it should be helpful that when I move the VLC window or am going to/from fullscreen, I can see the movie for a split second, and in full color. The rest of the screen stays B & W, though.Also, for some reason, when I play a movie, VLC open two windows: one with the video, and the other with a visualization and a title bar saying "VLC (X11 output)"
