    Hi sabasi,

    Is your laptop overheating? If so, clean the air vents:

    Below are the steps to clean the air vents:

    1. Check the vents on the computer to see if they are covered with dust and not allowing heat and air to pass through.
    2. Turn off the System.
    3. Unplug the AC Adapter.
    4. Remove the Battery.
    5. Use Compressed Air to blow the dust out of the vents.

    Note: Do not use your mouth to blow the Dust out of a Laptop. If using a can of compressed air use the can according to the directions on the side of the can as you can cause damage to the computer if used incorrectly.

    Please check your system's functionality in BIOS:

    • Restart the system and keep tapping 'F2' as soon as the Dell logo appears
    • The system should enter the BIOS (system setup).
    • Check if your system shuts down in BIOS as well

    I will also recommend you to update the BIOS:


    Note: The ac adapter should be connected and the battery should be at least 10% charged. Please disconnect all the external devices connected to the system before updating the BIOS. Please save all the unsaved data as your system will restart automatically while updating the BIOS.

    I'm having the same problem with a brand new inspiron 14z, seems to be when processor is high and the power cable is off and you connect it, or the cable is on and you remove it.

    I'm not sure, but it seems to be relatet to the change of video driver, from intel to amd, or the change of battery profile.

    My not-yet-one-year-old N411z displayed the same problem. It would power off whenever I'd do anything more than just web browsing -- it would even turn off on flash games. Watching hi-def video or doing anything CPU intensive would do the same.

    After going through the normal troubleshooting like BIOS, drivers, dusting the vents etc. to no avail, I downloaded the Core Temp software to see what my CPU was idling at and was shocked to see it idling in the 70s Celsius.

    System fan was working fine and there was no dust ball clogging the vents anywhere. So I took the heatsink apart and voila~ discovered the problem with dried up thermal compound.

    After cleaning and reapplying the thermal compound I had laying around, I'm currently running 1080i video and Core Temp software is telling me Core1: 50C Core 2: 39C.

    It's no longer powering off.

    I have had the same problem and cleaning does nothing.  I would follow what you are doing but it is Greek to me.  What and where is the heat sink?  What is the thermal compound?  Be most greatful to hear back from you as I am in Spain and have no way to communicate with someone (I don't speak Spanish well enough) for help with this.
