[GUIDE] Extract and Fix DSDT MSI Z77A-G43

[g.maverick]

Hi,

I had never nice issue.
Sleep worked just some time ...
I tried every thing found on the web.
My bios was patched like described here.
I'm not remember version of the patch.
Dsdt was also patched like describe here with no issues.

My best solution was to sell the MB and replace by a gigabyte z77 ds3h.

Now everything is working without problems.

Good luck

Thanks for the answer.
I'll try to patch the bios and see if I will solve the issue.
Finger cross!

Can you tell me how can i fix this error:
Not all control paths return a value(_ROM)
Reserved method just return a value(Buffer required for_ROM)
this is the code:

Method (_ROM, 2, NotSerialized) // _ROM: Read-Only Memory
{
If (IGDS)
{
OperationRegion (VNVS, SystemMemory, VRBS, 0x00010000)
Field (VNVS, ByteAcc, NoLock, Preserve)
{
VBRG, 524288
}


Multiply (Arg0, 0x08, Local0)
Multiply (Arg1, 0x08, Local1)
CreateField (VBRG, Local0, Local1, TBF)
Return (TBF)
}
}
