Thanks for the additional info!
Yes, notebook seems really slow for me, cause I'm using my book not only for the Internet and movies, but also for 3D rendering and video convertation. It has 12 Gb of RAM onboard, so I really want to use both kernels in max mode.
It's sad, but seems you are right - it always stays under 0.8 Ghz whenether how high load is, it's likely the LPM mode is enabled. I don't know who and why enabled it, cause notebook is really quite and has maximum 65 graduces of Celsium under the 100% CPU usage (using only 0.8 Ghz, of course). Seems it was a cheap and "ellegant" way to create such a power consumption and cooling conditions.
Ok, but now, how can I disable the LPM? Or check its status? Or enable Turbo Boost? Is there any adjustment/diagnostic utility available?
p.s. Finally I found needed BIOS setting: "CPU power saving mode". I disabled it, but all in vain - I have only 0.8 Ghz.
