[Guide] Laptop backlight control using AppleBacklightFixup.kext

[stevep0070]

Still none of the profiles in ApplePanels matches what the system is expecting.
You will need to experiment with other profiles

So I need to add the P's and S's to the ApplePanels from:

F%uP%04x
F%uT%04xM
F%uT%04xL
F%uT%04xD
F%uT%04xLD
F%uT%04xDL
F%uT%04x
AppleSense
F%uS%04x

What about the data values? still the same as F14Txxxx?

Adding all of them, and also trying them individually with a shorted patch is the way to discovering which pattern is expected...
Shortened patch:
Find: <2530 3478>
Replace: <7878 7878>

Im so lost. This entire list? And leave the values blank?

This entire list?

No. Only those that correspond to the profile format strings:

F%uP%04x
F%uT%04xM
F%uT%04xL
F%uT%04xD
F%uT%04xLD
F%uT%04xDL
F%uT%04x
F%uS%04x

So, F14Pxxxx, F14Sxxxx, and the other F14Txxxx profiles you already have.
If you get a match, then try each individually.

Ok and the same data from the F14Txxxx in the value column?

Yes.

 

[stevep0070]

Yes.

Done. Still no change. Any other ideas?

Read post #1, "Problem Reporting" (seriously, why do I need to keep repeating that?)

Hi, I've tried almost everything I could in the first post of this, guide but still no backlight control. Here's my info... any ideas about what I'm missing? Perhaps something to do with DSDT? (my patched DSDT is called DSDT1.aml)
