I ordered this PC 6 months ago and haven't got round to it yet, but I find that myself and many other users are having this problem.
Firstly, there is no support page for this model. I have no idea why, and this is extremely unhelpful when trying to find the most recent updates (there is the support assistant, but i'd prefer to be able to download these things myself.)
Secondly, the HD8670M switchable graphics has not been detected since i bought this. I have recently updated everything through the support assistant, then installed the latest graphics drivers to totally no avail.
Does anybody have a fix for this? I saw a previous thread what lead to nothing. Some people seem to have it available, but some don't.
