HP EliteBook 8740w sleep and wake not working.

Ideally you rename GFX0 to IGPU. Then rename DGFX to GFX0.

I can rename GFX0 to IGPU.
There is no DGFX, only PEGP.DGFX. Should I rename PEGP.DGFX to GFX0 or to PEGP.GFX0?

PEGP.DGFX is DGFX in subscope PEGP. You should keep the subscope, rename just DGFX.

Names in ACPI are 4-characters max. ACPI spec: http://acpi.info/spec.htm

Thanks, that's good to know.
Well, I did the renames with this patch

into_all all code_regex GFX0 replaceall_matched begin IGPU end;
into_all all label GFX0 set_label begin IGPU end;
into_all all code_regex DGFX replaceall_matched begin GFX0 end;
into_all all label PEGP.DGFX set_label begin PEGP.GFX0 end;

but the behaviour is the same.
The system logs show it trying to sleep (19:18:07) and to wake (19:18:24) but there's no error that I recognise.
