Hi, i can't get my brightness Key working, in console i see:

fn + F2 = Brightness Low
fn + F3 = Brightness High


When Press fn + F2 = ACPIDebug: EC _Q0B enter
When Release fn + F2 = ACPIDebug: EC _Q2B enter
When Press fn + F3 = ACPIDebug: EC _Q0C enter
When Release fn + F3 = ACPIDebug: EC _Q2C enter

How can i fix It in DSDT, i'm a bit confusing because the event when i release the Key didn't exit but generate another enter event as you can see...

Use only _Q0B and _Q0C

If using hotpatch, rename to XQ0B and XQ0C and implement the brightness code.
If not using hotpatch, remove body code for these methods and implement the brightness code.

Using Only _Q0B for Brightness down and _Q0C for Brightness up It works Only for the First click...

Then nothing, the keys didn't response more...

For the hotpatch i don't know how to Do It, i know how to rename the keys but i don't know how to implement Brightness code, can you explain me how to Do It?...

Thanks a lot
