I didn't expect a flawless system, but this unit was a lemon from the very beginning, as it was shipped with a keyboard that had issues w/the numeric pad, they sent another one (off brand generic), which worked at least. About 45 days in production we had issues with the unit wanting to restart, because the OS detected problems, upon diagnosis the bootable SSD reported flaws. We tried to get support from the vendor via Amazon email, and it was ignored, as they never acknowledged the issue. So we did some work around, but the unit progressively got worse, with issues of integrated video memory and the SSD kept failing. Our tech recommended to replace the mother board, since the bios diagnosis pop up different issues every time is executed. Overall the unit has been a nightmare, and the vendor isn't reliable.
