Hi, I just installed Sierra 10.12.6 on my Asus :
https://www.intel.fr/content/www/fr...ndard/acer-aspire-e5-575g-551m-H36226248.html

I'm trying to disable the Nvidia gpu because the battery lasts for less than two hours.
I tried using the guide (https://www.tonymacx86.com/threads/guide-disabling-discrete-graphics-in-dual-gpu-laptops.163772/)

When i use grep -l Method.*_OFF *.dsl, I get DSDT and SSDT-10
When i use grep -l Method.*_INI *.dsl, I also get DSDT and SSDT-10

These two files are attached to this thread, if you have any idea of what I am supposed to do I would be very grateful

Thank you

The ioreg shows Nvidia at _SB.PCI0.RP01.PXSX.
Confirmed in SSDT-10.aml, which is where _OFF is. The associated _INI is in the same SSDT-10.

Yes that's what I figured, so applying this patch should disable it ?
[PATCH]
into method label _INI parent_label \_SB.PCI0.RP01.PXSX insert

begin

//added to turn nvidia/radeon off\n

External(\_SB.PCI0.RP01.PXSX._OFF, MethodObj)\n

_OFF()\n

end;
[/PATCH]

That's what I was missing, so your example in the guide was
\_SB.PCI0.LPCB.EC0.SPIN
and mine is
SB.PCI0.RP01.PXSX.HGOF

am I right ?

No.
EC related code is inside your HGOF method.
Look at the code in the HGOF method.
