At first, was a tremendous laptop.  Value was through the roof.  Until the problems started.  For me, it was naturally out of warranty.  There is the well documented "black bar" issue.  A piece of the screen frame black plastic will separate and begin working its way down the screen.  Not a huge deal breaker, except for me it was a $1600USD laptop.The infamous "screen flicker".  To be specific, the screen will randomly display artifacts, or screen garbage. Occasionally it will freeze the laptop. It happens so frequently the screen is basically useless.  I tried all the searchable "solutions", updating drivers, BIOS, resetting PC, wiggling cables.  Adapting brightness and power settings. Something worked.Then one day the close lid button failed to properly detect the laptop as being closed.  This became a big problem because I was playing Cities Skyline at the time.  I placed the laptop on my bed and fell asleep.  Well, the laptop continued to run, without proper cooling keeping the fans on overnight eventually wearing out the bearing in one of the fans.Two months after, the screen flickering/artifacting came back with a vengeance.Lenovo is blaming drivers and Windows.  They do not "support" this laptop any longer so BIOS updates and such are not available.The only aside is I can use it connected to an external monitor.  But that defeats the purpose of buying a somewhat future proof portable device.I have literally tried every solution listed.  Some driver /OS updates make it slightly, slightly better.  Some make it slightly worse.I am about to open it up again, try a co.plwte static power discharge, cable fiddle and check all the other "solutions" one last time.Trash.
