Runtime D3 support on Lenovo Legion 5 (Ryzen 7 4800H, GTX 1660TI)

From @Cherenkov11’s instructions in this post:

$ mkdir rtd3 && cd rtd3
$ sudo pacman -S acpica
$ sudo acpidump -b
$ sudo chown $USER:$USER ./*
$ iasl *
$ rm *.dat

I then grepped for _PR3 and _PR0:

$ grep -ir "_PR3\|_PR0" ./*
./ssdt3.dsl:        Name (_PR0, Package (0x01)  // _PR0: Power Resources for D0
./ssdt3.dsl:        Name (_PR3, Package (0x01)  // _PR3: Power Resources for D3hot
./ssdt3.dsl:        Name (_PR0, Package (0x01)  // _PR0: Power Resources for D0
./ssdt3.dsl:        Name (_PR3, Package (0x01)  // _PR3: Power Resources for D3hot
./ssdt6.dsl:        Name (_PR0, Package (0x01)  // _PR0: Power Resources for D0
./ssdt6.dsl:        Name (_PR3, Package (0x01)  // _PR3: Power Resources for D3hot

So it looks like Runtime D3 is supported (I think - need confirmation).
