Thank you for your reply. It is possible that I could have pressed Fn + F11 by accident. And, at the time, I was unaware that there was a way to throttle the CPU on Samsung notebooks. Samsung Technical Support should have pointed that out; it would have saved me a lot of time.
I was very pleased with the “Samsung Series 7 Ultra vs Asus Zenbook Prime UX31A Touch Comparison Smackdown”. Those were my choices as I went to Best Buy last Saturday. I chose the Samsung Series 7 Ultra primarily because of its upgradeability. Moreover, it appears from forum postings that the ADATA mSATA SSD in the Asus Prime X31A has a TRIM issue. It has been said that while other manufacturers using the SandForce controller have resolved the issue with a firmware upgrade, inexplicably ADATA has not released it.
I ordered a pair of PC3-12800 SODIMM modules from Crucial. I will let you know how it affects the memory and graphics subscores in the Windows Experience Index. I am also considering upgrading the SSD but have not completed my research.
Samsung should do better than releasing in the U.S. market a stripped-down version of one of its better ultrabooks. The Samsung Series 7 Ultra was designed with an i7 processor, AMD HD 8570M switchable graphics, a 256GB SSD, and TPM security. I would have liked to order it with all the available options.
