I suggest (but now it is too late) to no to buy this model. It has a BIOS deeply customized, Ubuntu 17 doesn't work well, the computer is not able to logout properly (I don't know if it's a problem of the Ubuntu version or of the hardware), and if you want to log out you cant't, the screen gets stuck. This happened after the attemp to install lkde desktop. I also think that there is not fully compatibility with the hardware monitor, because I've experienced some problem visualizations, but I don't know if it all comes after the installation of lkde dektop environment. And, after three months of usage, this laptop stopped to work, there is a component that gets hot when you plug-in the battery. I suggest to not to buy this laptop, because I think that there is not fully compatibility with Ubuntu 17.
