Hi ! need some help with sony vaio i7 4500U intel ig _(hd4400) 8gb ram

ussing unibeast and updated usb 10.9.3 maverick. I have a 90% funtional mac. only have two issues ,


1º brightness ( i read about this in forums and i have the solution)

2º I am Unable to Power on with battery supply ,( I have to plugg it to the wall to power on , later i can put battery and unplug from wall.the system recognises battery and battery percent.

I was patched with rehabman patchs my dsdt and sleep /wake/reset /shutdown is 100% Ok.

Know someone how to fix my second issue?

thanks in advance.

#2 could be brightness issue. Fix #1 first.
 
Now my problem is only power up my laptop. Some one can help me??

Brightness control is not implemented correctly....

Haswell Brightness Fix:
DSDT Patches from here: https://github.com/RehabMan/Laptop-DSDT-Patch

Apply:
"Rename GFX0 to IGPU"
"Brightness Fix (Haswell)"
- rename patch must be done first and to all DSDT/SSDT that contain references to GFX0 that you're including in your final SSDT set
- Brightness patch must be done to the DSDT or SSDT that contains the definition for Device GFX0 (search for 'Device (GFX0)'
- Place DSDT and SSDT (if necessary) into a place where the bootloader will load them. For Clover, EFI/CLOVER/ACPI/patched (DSDT.aml, SSDT-x.aml where 'x' is a number). For Chameleon, /Extra/ssdt.aml, /Exra/ssdt-1.aml, /Extra/ssdt-2.aml, etc.
