How to turn off Optimus on your Gaming Laptop

Each laptop brand has a different way of using the MUX switch to enable or disable Optimus. This guide will show you where the setting is for all of the main gaming laptop brands.

How To Tell If Your Gaming Laptop Has A MUX Switch

Different laptops from the same brand may have different options to what’s shown here. In my experience, for the most, part they’re generally the same. That said, differences between generations of hardware are more common.

I’ve listed all gaming laptops that I’ve personally tested and covered if they do or don’t have a MUX switch here. This guide teaches you how to check for yourself if you have a model I haven’t covered.

Click on your laptop brand from the list below:


Acer

Open the Predator Sense software and select the cog icon from the top right. Click on “Discrete GPU only” to make the change. A reboot will be required to complete the process.

Alienware

I’ve only had the Alienware m15 R5 to test with this feature, and it does not have any front end software to use the MUX switch. You need to boot into the BIOS (power on and keep pressing F2). Go to the Advance tab and select “Enable Hybrid graphics” with the arrow keys and press enter to change it to the desired setting. Once complete, go over to exit, save the changes and leave the BIOS.

Aorus

Open the AORUS Control Center software. Select the “Manager” tab and toggle the “Graphic Switch” as needed. A reboot will be required to complete the process. Gigabyte laptops may be similar, but they are often resold Clevo models, so check the Control Center software.

Open the Lenovo Vantage software, on the right hand side there should be a switch for “Hybrid Mode”. Hybrid mode enabled means Optimus on, Hybrid mode off disables Optimus. A reboot will be required to complete the process.

I still can’t find it!

If in doubt, just look through the settings available through the laptop’s primary control center software. If there’s nothing there, have a look through the BIOS. Most laptops that let you toggle the MUX switch through software also give you the option through BIOS, but not necessarily the other way around, as is the case with the Dell G15 5515 mentioned above.

    Hi Jarrod,

    I have a Legion 7i (10865H/2080s) and the only time I was able to disable Hybrid mode was fresh out the box – no matter what drivers I’ve tried since then, when I disable Hybrid mode I get a blank screen on boot (can still get an output on an external display, so I can revert it back).

    Ever seen this issue? There’s a few similar stories on Reddit and such, but no concrete solution that I can see! Driving me up the wall, considering I only ever use it when attached to the wall!

      I’ve heard of similar problems but only when people do the opposite and disable the iGPU. I suppose for what ever reason the discrete graphics isn’t connecting to the screen, not sure why, could try DDU + clean driver install and make sure you have the latest BIOS, after that probably time to contact Lenovo support.

    I am using Acer Aspire E5-576G-57NY that uses Intel Core i5 8250U (Intel UHD 620 graphics) and Nvidia MX150. To my surprise, the Acer PredatorSense app works wonderfully to disable the Optimus.
