Not switching graphics from integrated to Radeon HD8850m problem

Hello fellow forumers, I come here to seek some help for my Samsung NP670Z5E-X01 laptop (all same specs).

I own this laptop for 3 weeks now and until few days ago, I've never plugged it out from power source since I didn't need to. And this is where all my problems started.

My Radeon 8850m worked normally as I wanted in certain applications when I set them to High Performance Mode, but since the day I plugged it out (and now it is back in the power source) Radeon HD8850m doesn't want to start anymore.

I made sure to set all settings to High Performance trough Catalyst Control Center, but it still doesn't want to start.







I am 100% sure it is some problem with Graphic Card because my laptop no longer heats up in certain applications nor it gives high performance.


I also noticed each time when I restart my laptop Power Saver mode turns back on even though I set it to High Performance trough control panel.




I hope to find solution with you guys.



Update: I dont recall doing anything else that could influence my situation except turning laptop off from power source to work on battery.

-Also after this I installed all newest Windows Updates version 6.2 build 9200. and also checked CCC if it needs any updates (it didnt need any).
