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.
