Inspiron 15-3521 DELL OEM Ubuntu image
Hello,
I recently bought an inspiron 15-3521(the one with i5 and radeon 7670), which had Ubuntu 12.04 LTS preinstalled. I wiped the whole disk shortly because I wanted to install windows 8 and then dual boot it with 'buntu 12.10.
Then I tried the 'normal' version of Ubuntu. It was a disaster - fan was almost constantly running on max power, it really didn't like the Integrated GPU/Radeon combo and as a result the battery was dying for about two hours. In windows, it easily lasts 5-6 hours. I tried Ubuntu, Mint, ElementaryOS, Fedora and openSUSE - same thing.
Turns out the version of Ubuntu, that was preinstalled was some kind of special OEM release for dell laptops/for the 3521/.
So my question is - Is it possible for me to get that OEM image, that was preinstalled on my computer before I formatted the hard drive? Also - is it even available in the 'my DELL downloads' page, I can't seem to get through the service tag check.

The problem was not CPU usage, the laptop has an Ivy bridge i5, it can handle unity. The problem is that linux doesn't like the intel/ati gpu combo and for some reason the discrete card is heating up quicky(even though it should pretty much not work, when it's not needed), which turns the fan on so it can keep up with the heat, which uses a lot more battery.
Disabling the discrete gpu did it for me - no constant fan running, normal battery life.

Hello svinqvmraka,
I would like to ask you to tell me in details, how did you do this discrete card disabling with vgaswitcheroo. I can echo OFF to the switch file and then it says that the discrete card is off, but the fan is running constantly. Should it go down? I think the problem is that on every boot the system starts with the default options (DIS ON). How did you achieve that the fan goes down and the card is really off? Do you use any method to apply these settings at boot time? I've tried to use the rc.local file, but somehow it didn't work. Please give me a full instruction from the very beginning. By the way, I called the Hungarian Dell Technical Support again (after 1 month) but they can't tell me any good news about this problem.
Thank you,
Wrezter

Hey wrezter,
I did what I posted a few posts back - just run the three commands:
1. chmod -R 705 /sys/kernel/debug
2. chown -R usrname:usrname /sys/kernel/debug/vgaswitcheroo (replace 'usrname' with your username)
3. echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
First thing - make sure you run all those with sudo - the chown and chmod commands need root access.
Second - For easy running, i created a bash script that runs those three commands all at once. Here is what my script contains:

Hi I use 3521 inspiron. Intel 2117u Cpu. No discrete graphics card. The laptop's fan works constantly.
Only an integrated card in laptop (HD Graphics 2500).
Is there any solution? The factory-installed ubuntu no on the disk.
Is there any difference between the pre-installed ubuntu and 12.04 ubuntu?
The pre-installed system can obtain a copy somewhere?
With the pre-installed ubuntu is constantly spinning the fan?
Or a list of drivers. Dell uses to the pre-installation.
(package name list)
Thank you in advance for your help.

Здравствуйте! Я так и не нашел на сайте OEM образа Ubuntu 12.04 от Dell, более того в нескольких постах утверждается, что его не существует. Хотя при покупке были установлены утилиты Dell и логотипы от Dell & Energy Star. Все ссылки, какие смог найти, смотрите выше в моих постах. Образ на rutracker.org выложил я, создав его из раздела восстановления. Дополнительные пакеты находятся в каталоге debs. После обновления ядра и BIOS стал сильно шуметь и постоянно работать кулер. После нескольких восстановлений из раздела плюнул и стал пробовать свежие версии Ubuntu. Сейчас стоит 13.10, хотя 13.04 на мой взгляд была стабильней. Еще стоит Elementary OS Luna. Кулер успокоился, индикатор батареи показывает то 3 часа, то 5 - не поймешь. HDMI в 12.04 тоже работал странно - на телевизоре не выставлялось родное разрешение.

Thanks, clempe! I answerd Dmitry K. Pre-install on my Inspiron 3521-6777 Ubuntu 12.04 differs from the original image of the presence of additional packages of Dell, which are not in official repository. I now use Ubuntu 13.10.
