Thank you MaLd0n for the DSDT.
I have a suspicion there is an issue with the CPU, I no longer think video accel. is the issue. I notice when the CPU go under load it stutters heavily this is without intensive task and just on the desktop, e.g. a youtube video in chrome is causing stutter etc or when initial boot, it stutters for a few minutes. Any ideas on this?
I don't particularly want to use this for video editing, I just want normal usage with a bit of coding but at the moment it's not very usable
EDIT: I've updated BIOS to latest, while this has not fixed my issue, it has made the DSDT.aml you patched for me not function I've reuploaded the files here from another runme output: http://s000.tinyupload.com/index.php?file_id=36589618916512122309
Thanks again!
