[James Geboski <jgeboski@xxxxxxxxx>]

I think the 15 series are somewhat similar but, I believe in terms of
the monitor identification it uses CRT-0 instead pf DFP-0 like the
L702X, if I recall correctly, which makes me think something else
might be a little different on the ACPI end, but I could be wrong.

Hopefully, someone with a 15 series machine can confirm or deny this for us.
