Just got a beautiful Ratel and everything is great.... except for this one little quirk. When watching videos the screen blacks suddenly after 10 minutes. Touch a key and it's back for another 10 minutes. Works fine while typing. Hmmm <System settings>,<Power> It's set "don't suspend" and "Never" show battery status in the menubar. I tried setting it to "1 hour" ect. to no avail. Hmmm <System Settings>, <Brightness and lock>. I set it to never. I guess this is where I turn off the pesky lock after it returns. Yep that works but it still shuts off. I click on the "dim to save power" and it works! That wasn't dimming that was total blackness. The whole deal was confusing. That has been the only thing and with a little searching. I think it could be an OS thing so the Ratel gets 5 stars. Hats off to System 76.
