MacBook Air, the Dell XPS 13 and Thinkpad X1 Carbon are a great example of design excellence in lightweight notebooks and are sought after by many users. But for Windows Camp notebooks, there's been a bad rumor lately: the Intel 7 Series CPUs only support Windows 10 systems and do not support Windows 7 and Windows 8. In order to confirm the authenticity of this message, I specifically investigated the drive

Dell has launched a developer version of the XPS 13 notebook in its official website, with a hardware configuration that is consistent with the Windows version, using the Intel Core i7 processor, 8GB memory and 256GB SSD, and running the Ubuntu 12.04 LTS operating system. In addition, the 1080P screen has some new features, the gamut from the original 45% to 72%, to provide a richer detail performance. The

number is 383, the difference between the two numbers is: 383-357=26,26 can be divisible by 13, therefore, 383357 must be divisible by 13.This method also applies to judging whether a number can be divisible by 7 or 11. such as: 283679 of the last three digits is 679, the last three digits of the previous number is composed of 283,679-283=396,396 can be divisible by 11, therefore, 283679 must be divisible
