First of all, THANKS.
Its so perfectly written.

I too have dv6 i5 with radeon (HD) 6490M. I wanted to install any linux OS.
I did try Ubuntu 12.04 but felt that the laptop performance declined + had problems with graphic card compatibility. The battery life i got with ubuntu was less than 90 min or so but with win7 i get more than 3 hours. Though i don't mind as my laptop is usually plugged in.
Hope you could help.

thanks again
Kartik :D

Did you install the ATI catalyst application and drivers for the video card? To get the best battery life it's necessary to use the integrated Video card not the ATI card. Under catalyst select the integrated card, it actually works pretty good so long as you are not gaming or doing openGL stuff.

How to configure additional speakers?

That helps a great deal, thanks a lot.
I'll let you know how I get on.

Robin,

That model looks very close to this one, the most notable difference is the ATI 7470M video card. I would suspect it will work just good as mine. The setup I have uses the ATI catalyst driver which has worked perfectly so far (though I know others have had difficulty in the past). Double check and make sure that driver supports your card.

As for the battery, I have done some limited testing and currently it uses about 18-21 watts on the intel card, and about 28-33 watts on the ATI card. Mostly I use the computer plugged in as a desktop replacement, and have not tried to see how long it could go. I do have a number of the power saving tweaks loaded in the grub defaults for the kernel: http://help.stedman.net.au/2011/10/xubuntu-1110-on-hp-dv6-6023tx.html. In the link, he gets it down to 13 watts and mine a little higher. I would bet you could get win 7 comparable battery life if you applied power saving tweaks. Note I do NOT have the VGA switcharoo installed as he mentioned, so it seems I'm not able to fully power down the ATI card (I'm relying entirely on the Catalyst driver). Having said that I mostly use the intel graphics as it is sufficient for most needs.

Hope that helps.

Scott

I'm thinking of buying a similar model for use with Ubuntu 12.04: http://www.amazon.co.uk/Pavilion-dv6-6c56ea-i7-2670QM-Processor-Windows/dp/B006OJ4JZI/ref=wl_it_dp_o_npd?ie=UTF8&coliid=IV8QNUZHQCS0H&colid=1MT20DV2O5NBX

Would this work fine also? Main questions are graphics card compatibility and battery life. How long's the battery lasting on your machine? Cheers, Robin
