I am revising the review as I was able to fix the issue with the BLACK screen after every windows restart attempt. Now it is the fastest and nicest laptop I have owned. The predator sense makes it very easy to get all the power you need out of the GPU and CPU.I added a 1tb SSD and a 2tb HDD. I had to move the INCLUDED SSD to the empty SSD SLOT and put my new SSD in the other SSD SLOT. For some reason ACER is putting the included SSD in SLOT 2 and this causes the computer to get confused on RESTARTS... It was fine on POWER UP.Tried to Install X-Plane 11.  The X-Plane 11 download install takes a while. When it was done the screen was black and was not going to come back on.... I had to hard shutdown computer by holding down power button. Screen came on after reboot I updated the nvidia and windows drivers, thought this would fix it but after a reboot the screen would not come on...Hard shutdown and reboot and screen worked... I am seeing multiple instances of the screen going black, keyboard lights if you touch a key, but the screen does not come back on... Only solution so far with a 12 hour old laptop is to hard shutdown and reboot...I see lots of comments of a similar problem in 2018... This is 2019, this problem should have been sorted out by now...
