Ubuntu :: Laptop Restarts Itself In It And GRUB
Jul 11, 2011
My laptop restarts itself frequently - full restart back through the bios screen to the bootloader, not just logging-out. It happens in Ubuntu 11.04 (32 bit and 64 bit), the Gnome 3 live CD from [URL] (the Fedora based one, run from a USB stick) and even from the GRUB bootloader menu. I have tried two different harddrives and two sets of RAM (all combinations) and the restarts still occur. They even happen when the hard drive is removed and Ubuntu 11.04 is booted from USB. Windows XP Media Center is also installed on the laptop too but the restarts have never happened when in Windows (even though they can happen in the bootloader!).
The memtest86 GRUB menu entry loads the blue screen with the title and memory info etc. but it seems to stop there and I don't think it's actually doing any tests, so I haven't been able to do a memory test. In Windows I have not installed any wireless network or 4-in-1 card reader drivers (among others probably), which is a possible reason why it does not restart in Windows, although I don't think GRUB has drivers for either of these devices either. My laptop is an Acer Aspire 5630 with the following hardware:
CPU: Intel Core 2 5500 (1.66Ghz)
Memory: 2GiB DDR2
Graphics: Intel 945 (integrated)
Audio: Intel HD audio with Realtek codec
Wireless: Intel PRO/Wireless 3945ABG [Golan]
It does seem that sometimes the restarts are caused by touching the keyboard (i.e. they happen exactly when I hit a key) but they also sometimes occur when I am not even touching the computer at all.

I come bearing a question that I hope I can get some info on. Here's the situation: I installed Ubuntu 10.04 Netbook Remix on my Acer Aspire One (didn't want it, but got it for free). I installed and am dual booting it with windows 7 basic. Both worked fine until this morning when the laptop ran out of battery and shut down.Now, on start up, the BIOS screen flashes, and its not the same BIOS screen, but I can't tell what it says, its moving too fast, the laptop then restarts. This problem may be bigger than the linux part of it

I installed Lucid Lynx some days ago. Whenever I try to access Vista from GRUB, the computer restarts. I haven't changed anything about how the computer starts.

I am having a re-occuring problem with Grub. The problem seems to occur about once every 15 or so times that I start up. Basically, it gets past the Samsung branded screen but before it goes to the Grub screen, the computer will restart - it just continually gets to this point and restarts until I shut down with the power button. The problem is easily fixed by re-installing Grub using an ubuntu CD. Things will then run fine for about a week and the same problem will occur.

I updated a RHEL 4 system today using up2date and when the system rebooted it just said "GRUB" on the screen for a few seconds and then restarted (and did this over and over and over).
I booted from a rescue CD and was going to reinstall grub.
Here's the kicker: this machine has two hard drives configured with software RAID 1, and I don't want to screw up the mirroring by tinkering with grub.
/etc/fstab shows that /boot is at /dev/md0 but "/sbin/grub-install /dev/md0" doesn't work ("/dev/md0 does not have any corresponding BIOS drive").
I have a bad feeling that if I do "/sbin/grub-install /dev/hda1" that I'm going to screw up my mirroring.

I just installed the newest version of Xubuntu using the LiveCD, I chose to install it alongside my current installation of Windows 7, everything went well it seemed, but now when I choose Windows 7 under the GRUB menu it just restarts my system and then takes me back to the grub menu, Xubuntu works fine though and boots fine, I tried sudo update-grub, didn't fix it.Heres the boot info from a script I found, but being rather poor when it comes to diagnosing Linux, I figured it'd be best to post this and see
Code:
Boot Info Script 0.55 dated February 15th, 2010

I don't really have any Linux experience. But I wanted to try it out. Now I'm afraid I did not set this up properly. Grub gives me 3 options:
Fedora (2.6.38.8-32.fc15.x86_64)
Fedora (2.6.38.8-26.rc1.fc15.x86_64)
Other
When I select <Other> to boot into windows... it starts to try to boot... but then flashes a quick blue screen & restarts. I tried to boot into Window's normal mode, safe mode, and command line... all just restart fdisk -l gives the following:

I recently purchased an Acer Aspire AS5517-5671 laptop [URL] Every time I try to install Fedora 12 it gets to the waiting for hardware to initialize then restarts. (using the F12 DVD) Ive tried both the default installation method and the basic video drive options
Ive successfully install OpenSuSe 11.2 on the laptop with little trouble however. So any idea if there is a work around, or is my laptop not compatible with F12?

I know this is an issue that has been brought up before and the solution I found is to recover Grub through the live CD [URL] However, this problem has occurred multiple times for me now. First time I thought it was just a freak error but it's happened multiple times within a short period of time (couple times this week) so I just wanted to get input on what's causing this and how I can fix it permanently. I've recently installed Ubuntu and I'm dual booting Ubuntu 9.10/Windows 7 Ultimate 64bit.

I followed a tutorial to install XP across my entire HDD. I installed Ubuntu 10.10 "Alongside another OS". Ubuntu loads fine, but when trying to load XP, the boot screen shows up, but then the computer restarts and returns to the GRUB menu.
I saw some threads on this site and tried to type: sudo gedit /boot/grub/menu.lst
In the terminal. It returned a blank text document so I'm not sure if that information was outdated. I then typed: sudo fdisk -l
And got this:
Not sure what any of this means, but I sure hope someone else does. I would say forget XP, but it's hard to let go of some of the games and software I use. I appreciate any responses, thank you.
I tried to format the table as it appeared, but the forum corrected the extra spaces.

I installed Ubuntu 10.10 to dual boot alongside Windows 7 on a Dell Inspiron. This worked fine and after restarting it seemed to be working normally, after the first boot into windows though when I tried to restart the laptop again I just get a blank screen with a blinking cursor in the top left instead of the grub screen.I'm still able to boot the LiveCD fine and tried to reinstall Ubuntu but the exact same thing happened? Anyone know what's going on/how to fix this?

Scenario new-clean laptop computer "Hundyx W765TUN" with this test results:
Devices:
- Intel Pentium(R) Dual-Core CPU T4300 @ 2.10GHz: well managed with Live-CD
- VGA NVIDIA G98M/GeForce-G105M: well managed with Live-CD
- CD/DVD Matshita UJ890AS: well managed with Live-CD
- Audio Intel ICH9/82801I: well managed with Live-CD
[Code]...
On every installation I've cleaned the MBR and made new partitioning at all for a single system. Tried to partition the disk manually and tried the "use entire disk" option with the automatic wizard. Same results on all cases, when the installation process goes well at all.
I've tried also to leave the computer some hours with the "GRUB Loading." message, but it doesn't move and remains with the same screen/text. Cursor remains blinking all the time under the GRUB message. In all cases Control+Alt+Del works to reboot. With hundreds of installations made, I've never found the same situation. It would be so strange to be a hardware issue.

About two weeks ago I installed ubuntu 9.10 desktop with a dualboot to my windows 7, which was already on there. everything went fine, but I couldn't configure my wireless to work, so after a few days I gave it a rest and basically forgot about; I just stuck with windows. anyways, yesterday night I installed a program called solidworks on my system. I woke up this morning, turned on my computer, and this is what happened-
it turns on for about 5 seconds, but when it hits "grub loading", after about half a second it restarts. it's basically an infinite loop, until i throw in a cd or hit f8, but I don't know what to do with either of those options, so I'm kind of stuck.
I'm posting this in the ubuntu forums because I have NO idea what's wrong with it, and no idea of where to start. I've got both installation disks, but I don't know what to do when I put them in. I've got an intel pentium 4 processor, and like i said, i've got a dualboot with windows 7 and ubuntu 9.10.

I'm currently using ubuntu desktop 9.10 (without desktop - I've removed packages) as OS on my server.But there's going on some strange thing ... There are about 8 users, and the thing is they many times user rar or some other disk-demanding programs. What I've noticed is that sometimes server will go with load over 20 (I know that's not good ...) and it will come down in few minutes and everything is OK, but sometimes it just restarts itself. I would like to disable that so it won't restart

I'm a WuBi user, and wanted to upgrade XP to 7, I've upgraded it partially when in XP. So as expected he messed up my grub.
But now I have the problem:
Every time I insert the Windows 7 DVD the pc says "Please press any key to boot up from CD/DVD" (as normal), but when I press the "any" key, the PC does absolutely nothing and just restarts.
Not to long ago I used the same DVD on another laptop for an equal upgrade (XP to 7) that went flawless.
My booting set-up is correct, cleaned the disc 500 times now, nothing out of the ordinairy done to my boot-screen or the BIOS... And as far as I know, no blue screen of death when installing the upgrade.
I haven't got a clue what I have to do.

this problem has really been getting at me, I can't figure it out at all. About a week ago, I came home from school and found that my computer was shut down (usually I leave it on), I started it up in Windows 7 and a Malware Bytes scan said it found a virus "clipb.exe". Well, I decided to remove it, and when booting up in windows it BSOD's saying IRQL_NOT_LESS_OR_EQUAL immediately at the login screen. Same result in safe mode and "last known configuration". Well, I decided to reformat just because I didn't want to go through too much trouble, and about a week later (today) it came back. I have no clue how, I was away from my computer. But the difference between this time and last time is, I can't start ubuntu at all. period. It gets to grub, and then after that gets to a black screen with no progress. The only thing I can do is ctrl+alt+dlt which restarts the computer.

whenever I use the files, which are mostly audio files (that is, I play them), after they are downloaded, the torrent files restarts again. So I have to wait for the file again to finish downloading so I can seed.

my X server restarts and boots me to the log screen when I start programs. I recently took the Nvidia card out of my computer and put in an ATI card. This is of course after uninstalling the Nvidia drivers through the restricted drivers interface. This worked out very well but eventually I went back to Nvidia. I removed the ATI drivers put in the Nvidia card and installed/selected the Nvidia drivers just as I did when I did this the other way previously. However now when I start just about any program the entire X server boots me back to the login screen.

My dads' hard drive went up a while back. So we got him a new one and installed Ubuntu 9.10 instead of windows. All was going well until About two weeks ago. The system restarts randomly. Not when anyone is doing anything in particular. Sometimes when we are using firefox, sometimes just sitting on the desktop, and never after any certain amount of time.Some times its after five minutes, some times after several hours. It's not a full out crash, the window for shutdown/switch user/restart comes up out of nowhere. When we close the window, it shows back up pretty quickly, but then the computer will just crash. While restarting, half of the time the computer won't make it past the bios screen before restarting again,and will continue the bios restarting cycle until the computer is unplugged. By the way, the system is a dell dimension E310 from 2005 with all of the original hardware minus hard drive inside, so if it is a hardware issue that wouldn't surprise me. Also, just one time after the restart I received the message "fsck from util-linux-ng 2.16" , if that helps at all.

Recently, I updated the kernel to the latest version and also installed Ruby and the Passenger module for Apache. The server was fine for a few days.However, today, it's been restarting randomly (usually a minute after I can log in).I tried booting with recover mode so I could view the logs for a longer period of time, but that caused it to restart before even allowing me to log in. Now, all boot modes will just cause the server to restart right after the GRUB messages appear.Our server setup complicates things. We have a RAID-1 mirroring for the /boot partition and a RAID-5 (software) for the / partition

I'm running Ubuntu 10.04, and ever since last upgrade a couple of days ago (I think), everytime I hit shutdown on the gnome-panel (admittedly, I haven't tried the command line shutdown) the computer restarts itself. This computer is dual-booted with Win 7, and the shutdown command there properly halts the system.

I had perfectly working lucid on my laptop (64 bit) which I installed from a live CD not wubi. I tried to upgrade with update-manager and everythingooked fine until I accidentally updated compiz from the cache before everything else finished. this made compiz stop working completely, which also broke metacity. I tried to fix this with multiple things: Downgrading compiz (failed to apply changes), sudo apt-get install -f, finishing the upgrade (see the following).
during the applying changes stage of the upgrade i got an error with almost every package it tried to apply (sorry I don't know what, but it said something about 'this package failed to upgrade and may be left in a broken state'. I let the upgrade finished and at the end it said 'Upgrade Finished but not all changes were successfully applied' and I shut down the computer. when I turned it back on everything looked fine until I past to the usplash screen. Then the screen went black, a bunch of error messages scrolled by too fast to read, and my system rebooted.
I tried recovery mode and another kernel choice at grub but all did basically the same thing. Windows still works as much as it usually does but I want my ubuntu back! I am OK with doing a fresh install if I can somehow recover a small amount of my data in my home folder. If you can tell me how to get into ubuntu from windows or something that would be great but I also need to know how to decrypt my home folder (I used the encrypting option in the installer)

I can chose Shutdown from the menu but the system gets to the point where the power supply should 'click' and shut off. It doesn't, it cycles and the system reboots. It wasn't doing this in 10.04, at least not towards the end prior to updating to 10.10 beta/rc/final. Also, 10.10 didn't do this either, until recently. (Current default = 2.6.35-22-generic)
Here's the funny thing though; if I choose a previous version from the GRUB2 menu, 2.6.32-21-generic for example, the login screen won't allow mouse nor keyboard control but will shut down normally w/ a single, momentary push of the Power Button. Now, there are folks w/ a seemingly similar problem, but in their case they can't shutdown at all. My trouble is a shutdown just triggers a restart.

since the launch of Natty I have been having stupid reboots randomly happening, no warning or otherwise occurs just a full reboot. This only seems to happen when browsing (FF or Chrome) and I have disabled every one of my addons and done the usual checks - baffled I am...So I had this with the upgrade I did on launch day, so naturally I did a full wipe and fresh install. Same situation - personally I cannot deal with this happening all the time so I went back with another full wipe to Maverick and all has been well.
Anyway I thought leaving this a few weeks would mean the community would have seen and squashed dealbreaker bugs so I re-installed yesterday, today the crashes came back again so I throw myself to your wisdom - anyone else seen this, know where I should be looking for ideas? My logfiles don't show anything prior to the reboot as an error.In all honesty I do not want to go back to maverick and cannot believe that Ubuntu have released such a bug riddled distro.
