I have a problem with my laptop. When I start it it locks CPU @ 800MHz and 8x multiplier, no matter what the load is. I've tried FireStrike test and Guild Wars 2 and it has been 800MHz flat. When I plug AC adapter out and in again, it goes back to normal frequency and multiplier (3.2~3.5GHz and x33-35 under load). I run default "High Performance" power plan and "Desktop mode" is disabled. I've already updated BIOS to A02 which suppose to solve this kind of issues. Is there any other fix or is it something wrong with the laptop itself?
