Never had a blue screen. Haven’t had the power off problem though there is a distinction between regular sleep and deep sleep. When coming out of deep sleep it boots up like normal and restores RAM from disk. Don’t have a touch screen but have the highest end, non-touch 4K screen Lenovo offered. They also offered a very good HD screen and a not so good 4K screen. Display is not as good as on a Mac but this is more a Windows problem than a hardware problem. If color calibration is an issue, you could have had them calibrate it for you for 25 bucks when you ordered it. I believe Lenovo support can send someone to calibrate later on too for a somewhat higher fee.
