<p>So with laptops, we can hide the dGPU from macOS with the little boot-arg called <code>-wegnoegpu</code> from WhateverGreen. But one small problem, the dGPU is still pulling power draining your battery slowly. We&apos;ll be going over 2 methods for disabling the dGPU in a laptop:</p>
<ul>
<li><a href="laptop-disable.html#optimus-method">Optimus Method</a></li>
<li><a href="laptop-disable.html#bumblebee-method">Bumblebee Method</a></li>

<h2 id="optimus-method"><a name="optimus-method" class="plugin-anchor" href="#optimus-method"><i class="fa fa-link" aria-hidden="true"></i></a>Optimus Method</h2>
<p>How this works is that we call the <code>.off</code> 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&apos;s, the Optimus method should work for most users:</p>

<p>To find out what EC you have, open your decompiled DSDT and search for <code>PNP0C09</code>. This should give you a result like this:</p>

<p>This SSDT is used to force enable our GPI0 for VoodooI2C to connect onto.</p>
<p>With most modern laptop DSDTs, there&apos;s a variable called <code>GPEN</code> or <code>GPHD</code> which are used for setting the status of the GPI0 device. For us, we want to enable the device.</p>

<p>So first things we need to do is find out what variable is used to enable our GPI0 device, lets open up our decompiled SSDT and search for <code>Device (GPI0)</code>. Should give you a desult similar to this:</p>

<p>What we care about from this is the <code>_STA</code> method:</p>

</code></pre><p>What we want is for this to always return <code>0x0F</code> when booting macOS, so we want to make an SSDT that will return <code>GPHD == Zero</code> in macOS.</p>
<p><strong>NOTE that you may have the other way around where GPHD needs to be set as <code>One</code> to return <code>0x0F</code></strong>. And your device name may also be different, don&apos;t throw random SSDTs in thinking it&apos;ll work</p>
<p>Once you found the variable and what it should be set to, grab a copy of <a href="https://github.com/khronokernel/Getting-Started-With-ACPI/blob/master/extra-files/SSDT-GPI0.dsl" target="_blank">SSDT-GPI0.dsl</a> and make the required edits. Then clean up with compiling it</p>

<p>With this example, we can see that we need both <code>SBRG</code> and <code>GPEN</code> to return <code>One</code>. If only one is present, it&apos;ll create some issues so in our SSDT we&apos;ll want to have both of them return <code>One</code>:</p>
