In the official Lenovo Forum there are solutions in which you should follow the installation order of the drivers, but also that to no avail. From the part of Lenovo, a solution is the forum for months promised, but unfortunately nothing is happening apparently. Unfortunately a waste of time and very annoying that it fails for me to such basics.
The Notebook:
The notebook makes a somewhat unstable impression, because quite a lot of plastic was used, which in some places strong yields when you press on it. Even the keyboard is in my opinion very soft, or are typing strongly after. But that side issues are not bother me further. Otherwise, processing fits. That part is super fast and barely audible. Even the display is extremely sharp and neat light.
The unit makes a good impression and ansich is certainly for Windows 8 users have monetary value. I would like to reserve the device, because in my opinion the price-performance ratio is very neat.
Unfortunately, I have to because of mangehaften Windows 7 Support send back.
Many Greetings,
