# Disabling laptop dGPUs
|
||||
|
||||
So with laptops, we can hide the dGPU from macOS with the little boot-arg called `-wegnoegpu` from WhateverGreen. But one small problem, the dGPU is still pulling power draining your battery slowly. We'll be going over 2 methods for disabling the dGPU in a laptop:
|
||||
|
||||
* [Optimus Method](/Laptops/laptop-disable.md#optimus-method)
|
||||
* [Bumblebee Method](/Laptops/laptop-disable.md#bumblebee-method)
|
||||
|
||||
## Optimus Method
|
||||
|
||||
How this works is that we call the `.off` method found on Optimus GPUs, this is the expected way to power off a GPU but some may find their dGPU will power back up later on. Mainly seen in Lenovo's, the Optimus method should work for most users:
|
||||
|
||||
To start, grab [SSDT-dGPU-Off.dsl](https://github.com/khronokernel/Getting-Started-With-ACPI/blob/master/extra-files/SSDT-dGPU-Off.dsl.zip)
|
||||
|
||||
|
||||
Next we need to get on Windows, and head to the following:
|
||||
|
||||
```text
|
||||
Device Manager -> Display Adapters -> dGPU -> Properties -> Details > BIOS device name
|
||||
```
|
||||
|
||||
This should provided you with an ACPI path for your dGPU, most commonly:
|
||||
|
||||
* Nvidia dGPU: `\_SB.PCI0.PEG0.PEGP`
|
||||
* AMD dGPU: `\_SB.PCI0.PEGP.DGFX`
|
||||
|
||||
Now with that, we'll need to change the ACPI path in the SSDT. Main sections:
|
||||
|
||||
```text
|
||||
External(_SB.PCI0.PEG0.PEGP._OFF, MethodObj) // ACPI Path of dGPU
|
||||
```text
|
||||
|
||||
```text
|
||||
If (CondRefOf(\_SB.PCI0.PEG0.PEGP._OFF)) { \_SB.PCI0.PEG0.PEGP._OFF() }
|
||||
```
|
||||
|
||||
Once adapted to your config, head to the compile section
|
||||
|
||||
|
||||
## Bumblebee Method
|
||||
|
||||
With some machines, the simple `.off` call won't keep the card off properly, that's where the Bumblebee method comes in. This SSDT will actually send the dGPU into D3 state being the lowest power state a device can support. Creit to Mameo for the original adaptation
|
||||
|
||||
To start, grab [SSDT-NoHybGfx.dsl](https://github.com/khronokernel/Getting-Started-With-ACPI/blob/master/extra-files/SSDT-NoHybGfx.dsl.zip)
|
||||
|
||||
Next we need to get on Windows, and head to the following:
|
||||
|
||||
```text
|
||||
Device Manager -> Display Adapters -> dGPU -> Properties -> Details > BIOS device name
|
||||
```
|
||||
|
||||
This should provided you with an ACPI path for your dGPU, most commonly:
|
||||
|
||||
* Nvidia dGPU: `\_SB.PCI0.PEG0.PEGP`
|
||||
* AMD dGPU: `\_SB.PCI0.PEGP.DGFX`
|
||||
|
||||
Now with that, we'll need to change the ACPI path in the SSDT. Main sections:
|
||||
|
||||
```text
|
||||
External (_SB_.PCI0.PEG0.PEGP._DSM, MethodObj) // dGPU ACPI Path
|
||||
External (_SB_.PCI0.PEG0.PEGP._PS3, MethodObj) // dGPU ACPI Path
|
||||
```
|
||||
|
||||
```text
|
||||
If ((CondRefOf (\_SB.PCI0.PEG0.PEGP._DSM) && CondRefOf (\_SB.PCI0.PEG0.PEGP._PS3)))
|
||||
{
|
||||
// Card Off Request
|
||||
\_SB.PCI0.PEG0.PEGP._DSM (ToUUID ("a486d8f8-0bda-471b-a72b-6042a6b5bee0"), 0x0100, 0x1A, Buffer (0x04)
|
||||
{
|
||||
0x01, 0x00, 0x00, 0x03
|
||||
})
|
||||
// Card Off
|
||||
\_SB.PCI0.PEG0.PEGP._PS3 ()
|
||||
}
|
||||
```
|
||||
|
||||
Once adapted to your config, head to the compile section
