I recently purchased the dv6 quad edition laptop with the intel i7-2670QM processor. It already has 4 cores, and I have no need of the hyperthreading to divide them into 8, as I'm not even able to use all 8 if I wanted to. I was hoping to be able to turn it off so as to increase the power of the individual cores. I could be wrong, but it seems to me that if a core is cut in half and running at 100%, it's performance would be improved by having access to use the whole core for the single thread. I've been looking around and it seems that a lot of people have similar issue, but I'm just wondering if there is anything that I can do with the BIOS in order to open up the ability to enable/disable hyperthreading. It doesn't really make sense to me that it is disabled for hp in the first place...

If there is not a setting in the bios to disable processor hyperthreading then you cannot. No the bios cannot be modified to do it, sorry.
A similar question was asked on this forum, very smart people over there, and it can only be done in the bios, but there is a complex solution for disabling some of them for any given program, see answer by member Breakthrough.
