Even when you set up different programs failed the device. There were rattling sounds and then came even more to a logon screen. With other computers I have at the Sony Support inquired who shared my way in the BIOS of the computer. The then worked well. There was then but an indication that the hard drive is not recognized. Then I returned the unit to Amazon. The offered me then a new device, in which then the delivery time lengthened greatly, perhaps hung with the change from Windows 7 to 8 together. Then they offered me a successor to the laptop, which was slightly more expensive, but which I then bought. The unit I have for a few days, it is operating normally.
