This is the screen after "Test this media & start Fedora-Workstation-Live
25_Beta":

This is the output of dmesg after "Start Fedora-Workstation-Live 25_Beta":

That's a 4.8.0rc7 kernel, lots of bug fixes since then and are in the
final release kernel.
The dmesg shows a bunch of ACPI errors, I can't tell if they're
critical. Does this laptop have USB-C? I wonder if you're running into
a variation of the bug I'm hitting
https://bugzilla.redhat.com/show_bug.cgi?id=1381039
which I still need to do an upstream bug writeup for but have been
preoccupied with an HP spectre sleep bug, which looks like some intel
folks are zeroing in on
https://bugzilla.kernel.org/show_bug.cgi?id=185521
