Did you try PNLF DSDT patch for brightness:

Code:
#   Brightness control fix
into device label PNLF remove_entry;
into scope label \_SB insert
begin
Device (PNLF)\n
{\n
	Name (_HID, EisaId ("APP0002"))\n
	Name (_CID, "backlight")\n
	Name (_UID, 0x0A)\n
	Name (_STA, 0x0B)\n
}\n
end;

Your solution was possible thanks to the brightness option:)
However, even at maximum brightness is still dark.
How do I fix?

It could be EDID issue. You can inject EDID in DSDT. See: http://www.tonymacx86.com/mountain-...orks-though-intel-hd-3000-a-4.html#post648787

Tried in that way, but did not fix:cry:

Did you check your work? (eg. look in ioreg explorer for the EDID injection under GFX0 device).

You might also try ACPIBacklight kext for controlling brightness...

I don't know what you mean by 'But Disabled BrightControl And DisplaySetting see BrightControl but NotControlled'

But make sure you followed all instructions for using ACPIBrightness (which involves DSDT edits...)
