The notebook is very well made, the fan is pleasantly quiet and only under proper utilization through performance tests it is loud. Turbo - Boost the processor is functioning properly, the temperature of the hard drive and the processor remains in the specification. USB 3.0 is really fast with countries meet peripherals. The first impression I am completely satisfied, as the buyer of the "Glare" display should be aware that reflects of course, but precisely HD content is super brilliant. What really annoyed me, however, is that no media was (except the internal Fetplatte) supplied, the Rescue DVD (Double Layer 2 or more 4.7 GB blanks) itself must be created and even came with the operating system DVD. And with only one partition on the 640 GB hard drive ... No, there are two partitions, but the second is the recovery partition and neither visible, nor with an assigned drive letter. After I but, if you have multiple partitions, one as a system, the other for the data (users), which facilitates a backup, I want to use the function of Win7 to shrink the existing partition and create a data partition. But the existing partition could not shrink to less than 300 GB. So a lot of work to wishes the notebook and configure "sizes" just what only with a certain experience, care in handling the data (and the operating system !!!) and using - necessary indeed free, but to - external tools to create an image, new partitions and restore functions. An original Win7 DVD is to be recommended absolutely, otherwise you get the 100 MB on a system reserved partition (exclusively for Win7) is no longer there and the system will not boot. Please, dear SONY, sets but at least one OEM disk with Win7 Home Premium at !!! After all the time-consuming action, I can only say that the notebook is worth its price.
