Hardware :: Computer Automatically Shut Itself Down If It Overheats - Thermal Protection?
Jan 3, 2010
I am considering trying out gentoo linux on my machine and wanted it to compile while I was gone (going to be gone for a week). I just want to make sure that my system will not MELT while I am not there to make sure everything is okay. I have a pentium 4 prescott. Will my computer automatically shut itself down if it overheats? I've heard its supposed to but sometimes is too late. Can I trust it?

I purchased a macbook (for cheap) without a hard drive and decided to go with Ubuntu 10.10 on my new drive.
This laptop has serious overheating issues. I installed the sensor applet and the fans are not coming on, even when the core temp exceeds 167(f). The base of the laptop becomes hot enough to fry an egg on.
I'd like to find a way to make the fans come on in an automated fashion (without having to do it at the command line each time I want them to come on). I'd even be happy with them on all the time if that will resolve the issue, as the laptop overheats until shut down / freeze every time I use it.

So I forgot how to do something in Compiz and I quickly Googled it to find the answer. On the first or second link I clicked, a pop-up box opened from Firefox saying that I should scan my computer. Immediately, I pressed the X button, but a page started to load that tried to "scan" my computer. I closed out Firefox and re-opened it. I did the exact same search again on Google, but I clicked on the cached view of the site. It was harmless enough--a blog with some ads on the side of the page. I'm assuming that it was one of the ads that somehow must have taken over the page.
Anyway, I know that the discussion of anti-virus programs is not anything new, but I would like to know if this virus may have affected Ubuntu. What would you guys recommend in this case?Also, after running the update manager, I received a pop-up box asking if I would like to update Grub. Is this a normal part of the update, or could it be a virus? I'm a bit paranoid, being from the land of Windows.

If I click on the shutdown bottom (in my lower panel) I get an new window to choose if I really want to shut down or restart or suspend or hibernate. Under that alternatives there is an text that says: "[...] The system will automatically shut down in 60 seconds." Why is the text "60" not running down like a countdown? Can I set another (shorter) time for the automatic shutdown (10 seconds)? If so, where? Or shut I just make another bottom to shut down immediately?
I use (normally) OpenSuse/SUSE Linux
Release 11.1
Kernel Linux 2.6.27.45-0.1-pae
Gnome 2.24.1

OK, so basically my problem is that I can't log out, shut down, or restart my computer through the GUI. The thing is, it used to work. Note: this started happening right after I put in the lock / logout widget, but it's really a pain to have to go through the Kickoff menu to lock the screen each time, and leaving my files, online accounts, and what's on my screen open to anyone who wants to snoop is not an option. I may have to just suck it up and lock the screen the old-fashioned way, but only as a last resort.
Configuration: An older Gateway (idk the exact specs) desktop machine with Windows XP and Kubuntu 9.10 Karmic (dual-boot)

Since a long time I have a problem when shutting down my computer. I have ubuntu 8.04 installed, and I do install regularly all the updates including new kernels, etc. Here are the symptoms: After pressing "shutdown" (or issuing a command in terminal) it happens (always) that the screen is still working at the end of shutdown process (ubuntu progress bar is at minimum and it stays visible). Also, CPU fan is still working. However, power and HDD lights go off.
The only possible way to shutdown computer at that moment is holding power button for 5 seconds. However, restart works OK. Now, I am sure that shutdown worked earlier fine, but unfortunately I cannot remember when the problems started: either when I installed 8.04 or after installing some of the kernel updates. Configuration: Asus 5pgl-mx motherboard, 1.5 GB ram, nvidia graphic card (sorry, not sure what model), etc.

I have had an issue with the log out since yesterday. instead of shutting down the computer, the computer loaded the GDM. The only way to shut down is to click the log out on the GDM. What to do to resolve it?

I've come across a problem just recently where my laptop will restart after I shut it down from within Debian. I've looked into my BIOS for anything that might trigger this, but could not find anything. I run Debian Testing 64-bit on a Dell Inspiron 17R laptop.

I seem to get different options depending on the user. On my main, admin user, when I click on the `power button` icon on the right of my taskbar, I get a choice of:
shutdown
restart
suspend
hibernate
and if I want to log off I click on the start button.but when I log on as my `guest` user, who has next to no permissions, I get log off, switch user etc on the `power button` icon. It would be nice to have all these options on the `power button` icon on my admin user. Can this be achieved? Why are they different?

I'm going to guess this has to do with me updating yesterday, as there were no problems before that. Which kind of ticks me off, because I came back to ubuntu because I got tired of micromanaging updates in arch.
Audio is down. The volume can be changed, but it isn't reflected in the volume icon at the top of the screen. Sound preferences show the only output available is a dummy speaker. When I try to restart or shut down, it just logs me out of my profile and takes me to the login screen. As always, if you need more info, just tell me where to find it.

I'm stuck in the "log off" mode. I don't get the shut down menu. It started when I turned the computer on today. I got a verbose boot up and had to login and enter password and run "startx". Then I got a gray screen before the splash screen.
I had been trying to get alsa to start in the "runlevel" section yesterday, could I have messed something up in there causing this?

When I shut-down the computer from OpenSuse 11.4, it does log out and exit the operating system but the computer does not turn off. Can this possibly be corrected?

Brand-new to Linux. Using a computer with openSUSE 11.3 (64-bit) freshly installed. Install went flawlessly without any kind of error messages.
Hardware used: MSI X58 Eclipse, Intel i7-920, 6 GB memory, Seagate 500 GB SATA.
openSUSE is the only OS installed.
After the install is finished, all programs work fine. HOWEVER when I try to shut down/restart the computer nothing happens! I basically have to use the power off button to shut down...

Code:
sudo shutdown now
command does not shut the computer down
When the command is typed a, all the programs are closed and proceeds to shut down. But after some time, screen gets stuck(plymouth animation stops moving). But the computer is still working. Fan is running , Power LED is on. LED showing hard disk usage blinks at equal time interval. There is no problem in shutting down using the button on panel. So I suppose it is not a hardware problem. More over there is no problem in windows. The graphics card is Nvidia Geforce 7300GS. I am using proprietary Nvidia driver.

I have installed Linux Mint 10 on a HP Pro Book 4720s, see here: [URL]
After the installation I wanted to shut down the PC and used the button in the menu. Then appears the Linux Mint Screen and nothing happens.
I could just shut down the PC by pressing the power button for a few seconds, but that isn't a solution.

Last night I decided to upgrade to Natty Narwhal 11.04 from MM10.10. I tried to leave it to install overnight.
Some bright spark turned off the power supply to my computer.
I don't know exactly what stage the installation was at, but it must have been installing the upgrade at least, because I'm now locked out of my computer.
Boot up progresses until the ubuntu loading screen. At this point is says,
'Ubuntu 10.10'
The disk drive for / is not ready yet or not present Continue to wait; or press s to skip mounting or M for manual recovery.
(If I press 'S', it says something like 'cannot find /tmp folder')
I don't know if the upgrade installation was completed, but I suspect not, because the power was turned off just an hour into the installation. Also it still tries to load Ubuntu 10.10.
Anything I can do besides formatting for a fresh 11.04 install? If only to save some files?

I could be wrong, but I swear that when I first considered switching to Linux a few years back the gnome windows manager's main menu had an option to exit said windows manager. There is obviously no such option now. Looking at some other forums, it seems that you can START gnome properly... but to exit the windows manager you have to kill processes? If I want to close down the Gnome WM without rebooting the computer - say, to just try TWM alone, or some other WM - there must be a 'legal' way to do it.

My computer won't shut off unless I just hold down the power button. Everytime I try System > Shut Off it just turns off, then restarts. My computer screen will sometimes just 'turn black' and become unresponsive, and I have to shut it down and restart. (The longest I waited was a few minutes with no response. How do I get customized mouse pointers? When I download something and 'extract' it, how do I know which file I'm supposed to open after I click 'show the files'? I've downloaded a few things and extracted them but I'm assuming I must do more, since they are not on my applications. Which is the best browser to use on Fedora? I love Opera, but for some reason my internet is twice as slow on Opera as it is on Firefox or Chrome?

I have v 10.10 and I had to hook up with ethernet cord to download and activate both broadcom b43 and sta drivers. Once they were both downloaded and activated my wireless worked fine. (Also I have an hp mini 210-1000 if that helps.) After unplugging my laptop and using it, if it dies or if things are running really funky and it seems like it could use a restart, or on one of the many occasions where I am not going to be using it for a few days and just shut it down, as soon as I start it back up.
I find that sta driver still says activated under system - admin - additional drivers, however the b43 now says inactive, and my wireless wont connect to any router, even though it can detect them, until I connect with the ethernet cord and redo the whole driver activation for both, and then restart. This happens every time, and although I don't often take my laptop out of my room, my router is away from my desk, so this is a major inconvenience when i have work to do, or if I were to ever take it out somewhere with me.

I have experienced this problem a couple of days now.The ubuntu-syncd process seems to create a ubuntuone-sync-<user> process. This restarts in an infinite loop and creates overload and the cpu to overheat.I have stopped the ubuntuone-launch process in the Startup Applications, but this is not really what I want.

I have done a clean install of Ubuntu 9.10 (from the CD), single OS on the machine, it seems to be working perfectly alright (better than windows 7 which was previously installed).Only one problem I am facing right now is when I open lot of firefox tabs, I can hear that the processor or fan starts making a lot of noise and eventually system shuts down abruptly, i can feel that the machine heats up. Than I have to wait for few minutes to let it cool and than start again. If i use firefox with (lets say) 2-3 tabs open, it works ok. but when i open over 4-5 tabs, it goes mad.

Offlate I installed F11 i586 on my laptop. F11 shares the hard disk with Vista Home Premium 32-bit. The problem is that when running F11 (or even Ubuntu), my system shut off suddenly(not a normal OS shut down, but a sudden power off without any warning). This could have been a hardware trouble(heating) but it doesn't happen with Vista.
Machine specifications:
Maker: Toshiba
Model: Satellite L305D-S5881
AMD Turion X2 Dual Core Mobile Processor RM-70
3072 MB 800 MHz SDRAM
I don't want to open up my machine unnecessarily, if it isn't a hardware issue.
I am not sure how to verify the bit length of the machine and the OS and does it create a compatibility issue ?
Your advise would be highly appreciated.
