    My laptop has shut down several times while using youtube after short periods of time. I can feel heat coming from the bottom. Just before it shuts off it displays a black screen with some text on it, lasting about a second.

    I'm running Xubuntu 12.04. I have tried running it on both Adobe Flash player as well as HTML5. The only proprietary driver it has is for the WiFi card. Laptop is running dual boot with Windows Vista. Don't know my way around Linux too well, so simple explanations would be much appreciated.

    system specifications (in case they might be helpful in diagnosis):

    • Dell Inspiron 1525 (from 2008-09)
    • Intel Celeron 2.00 GHz
    • 2GB memory
    • 32 bit
    • 110-ish GB hdd
    • graphics card is "mobile Intel 965 express chipset family"

    think i got what you were talking about entered

    grep -iE "(emergency|temperature)" /var/log/syslog
    

    got

    Jun 20 01:19:24 ubuntu kernel: [ 3617.333801] Critical temperature reached (99 C), shutting down.
    Jun 20 01:34:21 ubuntu kernel: [  867.196196] Critical temperature reached (99 C), shutting down.
    Jun 20 02:43:52 ubuntu kernel: [ 1708.282274] Critical temperature reached (99 C), shutting down.
    

    those are the three times it over heated -- entirety of it:

    thanks a ton for the help Cleaned fan works smoothly now, couldn't figure out the amd propriety driver though

    As for the hardware part:

    I solved the same problem on the same model (with Windows) recently. You are lucky, in this model it is really easy to clean the cpu cooler. You may only open the small cover of the CPU/RAM, unscrew the cooling system and it's cover and clean the dust from the fins. NOT only the dust from the fan. Think that it is the only way your laptop "breathes" and it is blocked with a "blanket" made of dust! You may also replace the thermal compound. These two together will for sure make things a lot better.

    Videos such this may help you. (you need only the first two minutes of this)

    As for the software part:

    Try the AMD's proprietary driver for the GPU. In my case (other model), it lowered the temperature a lot. Although, maybe things have changed latelly as for the power-saving features of the open source drivers.

    shutdown - Dell Studio 1558 shutting down due to over heating
  • Johnny

    My system (DELL Studio 1558) gets shut down while using GNOME Shell on Ubuntu 11.10 without any message, because the system over-heats. The fan below the processor is also not working. Does any one know what to do?

    According to this page on Dell Support,

    Problem: May randomly shutdown

    The Studio 1558 may intermittently restart or shut down during use.

    Resolution: Update the BIOS

    To resolve the issue, download and install BIOS (System Setup) version A04 or later. If you need help to download or install the BIOS, click here for downloading and installation instructions.

    Your next question/step would be how do I update BIOS on your Dell from Linux? For that the answer is provided by our moderator Bruno Pereira here. Following is the information provided in that answer:

    Dell has a very nifty utility to download and apply latest BIOS to their computers that are using Linux. It should theoretically run without any problems and you can run it in Ubuntu.

    Please visit their page for more information, there are precise instructions there

    Here are the instructions from the linked page

    sudo wget -q -O - http://linux.dell.com/repo/firmware/bootstrap.cgi | bash
    sudo apt-get install firmware-addon-dell
    sudo apt-get install $(bootstrap_firmware -a)
    sudo update_firmware
    

    Please note: I have not tested this myself, you might first drop an email to Dell support to ask them if this method deprecated or if there are any issues with it.

    I've had the same issue on my Studio 1558 since I purchased this thing! It's been defective from day one and Dell's solution is to update the BIOS. Mine is up to date (A12) and it still randomly shuts off with and without the AC plugged in! And yes, it is due to overheating. Someone, who still has a Dell warranty managed to get theirs fixed through Dell and they replaced the entire Motherboard for him. But he also did confirm that it is an overheating problem that the Studios have. Someone else got a cooling stand and he hasn't had a problem since. I'm going to purchase one (about $25) to see if it helps. Good luck!
