I bought this laptop with a market companions from Amazon, because it greatly reduced the offer was there (due to a scratch on the lid). The unit is not priced in while the upper class, which is why you probably should expect a lesser extent, but that leaves much to be desired presented here left. When delivered, the device hung shutdown now and on, both among the included Windows 8.1, as well as an installed parallel Debian 8. After a BIOS update the shutdown problems were indeed resolved, but appeared two new problems : From time to time, especially when the device was longer, then the Ethernet port is not working. Neither Windows nor Debian ever see the network card, she dives for example under lspci not. A reboot does not help, you have to shut down the equipment off and on again. In addition, USB devices are no longer detected at startup. This prevents the one to boot from a USB flash drive, to the other but the USB device also provides the OS launched not; it must be back-off and re-infected. I hope all will be resolved through further BIOS updates, otherwise the thing is to use a pain.
