[Solved] Dell Inspiron 15 3521 laptop with Radeon Graphics card overheating issue solved

It is a headache for Dell Inspiron 15 3521 laptop users that the laptop gets overheated and fan runs continuously in Linux operating system. After many experiments finally I got a solution. I don't know whether it is the proper procedure. Anyway I got positive result and now battery status indicates about 4 hrs backup. But even sometime, fan runs. But most of the time, it is peaceful :D Check whether it is working for you!

I downloaded Ubuntu 12.04.4 LTS version (ubuntu-12.04.4-desktop-amd64.iso, you can download it from this link, select from the list) and installed in my computer. Because I found that official drivers (no need to download any files) for my graphics card (Radeon HD 7600M) is provided for 12.04.4 LTS version. Some other newer versions are also supported, but I chose LTS version.

After installing Ubuntu. Go to terminal Ctrl+Alt+T

Then run following codes.

sudo apt-get update

sudo apt-get install fglrx fglrx-pxpress

Now the graphics card drivers are installed on your system.

Then Reeboot your system

After turning on, again go to terminal and run following codes.

sudo amdcccle

 Now AMD Catalyst Center will be opened.



Go to Switchable Graphics option and select Power-saving GPU for improved battery life and click Apply and OK. Then reboot the system.

After turning on, again go to terminal and run following codes.

sudo apt-get upgrade

sudo gedit /etc/default/grub

Then the following screen will be appeared.


Change the highlighted line as follows.

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi='!Windows 2012' radeon.modeset=0"

Then run in terminal sudo update-grub

Then Reboot your system. After two-three shut down, there will be improvement in the overheating. In my laptop, it works. Try it!
