Hi all,

I have a problem with my Sony Vaio SVE1512X1ESI (HM76 chipset, ivy-bridge cpu and HD4000 mobile graphic card only, there aren't other graphic card).

I successfully enabled display brigthness control following this guide:

http://www.tonymacx86.com/yosemite-...ching-dsdt-ssdt-laptop-backlight-control.html

but.....
If I put the laptop in sleep manually or if it goes to sleep automatically (with opened lid), the brightness and the brightness control work well after wake up (they don't work rarely).
If the laptop goes to sleep by closing the laptop lid, after wake up the screen brightness is always very very low (the screen is nearly black) and the brightness control doesn't work despite I can see the brightness slider moves from min to max position.

What can I do?

Ask me if you need other informations.
Thanks.

Download patchmatic: https://bitbucket.org/RehabMan/os-x-maciasl-patchmatic/downloads/RehabMan-patchmatic-2015-0107.zip
Extract the 'patchmatic' binary from the ZIP. Copy it to /usr/bin, such that you have the binary at /usr/bin/patchmatic.

In terminal,
Code:
if [ -d ~/Downloads/RehabMan ]; then rm -R ~/Downloads/RehabMan; fi
mkdir ~/Downloads/RehabMan
cd ~/Downloads/RehabMan
patchmatic -extract

Note: It is easier if you use copy/paste instead of typing the commands manually.

Post contents of Downloads/RehabMan directory (as ZIP).

Also, post ioreg: http://www.tonymacx86.com/audio/58368-guide-how-make-copy-ioreg.html. Please, use the IORegistryExplorer v2.1 attached to the post! DO NOT reply with an ioreg from any other version of IORegistryExplorer.app.

And output from:
Code:
kextstat|grep -y acpiplat
kextstat|grep -y appleintelcpu
kextstat|grep -y applelpc

System: manufacturer/model + bootloader(Clover/Chameleon/Chimera)
CPU: detailed CPU model + motherboard chipset
Graphics: all graphics devices + laptop internal screen resolution

For example, typical Ivy laptop:
Mobo: HP ProBook 4540s (Clover)
CPU: i5-3320m/HM76
Graphics: HD4000, 1366x768

Use CPU-Z on Windows to find CPU (Core iX-xxx) and motherboard chipset (HMxx), and graphics capabilities. For a laptop, these details are important and affect critical installation procedures.

The ioreg shows brightness set relatively low (0x17d of 0x710).

Other than that, looks relatively normal.

ok.

So it's difficult to understand the problem that occur after wake up.

It is probably something your DSDT is doing. If you have some programming background, debug it with ACPIDebug to try and see the difference in code path for lid sleep/wake vs. normal sleep/wake.

What do you think about the setting of my laptop? In general, do you see wrong things or mistakes in the files' contents attached two post ago?

Mostly normal (from ioreg), except for:
- PXHCD for Intel USB3...
- unsupported WiFi card installed
