I was looking forward to the store so that the notebook is a bit faster, there is difficult if you want to use it on vacation and it depends continuously, despite minimal programs and applications. Unfortunately, I did not open the unit before storage order and am taken in by a video showing the exchange, unfortunately, I have a different device version. Turns out that in my series of memory is soldered. A real design flaw, because the device would otherwise fulfill his ministry fully. So memory back. But delivery and service top, a memory flopp- which is on my device. So before you come up with the idea to upgrade the 1015 BX - Screw and pure look. And if that does not look like the video tutorials on the Internet for the exchange of memory looks - Stay away.
