Optimus 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 whats shown here. In my experience, for the most, part theyre generally the same. That said, differences between generations of hardware are more common.
Ive listed all gaming laptops that Ive personally tested and covered if they do or dont have a MUX switch here. This guide teaches you how to check for yourself if you have a model I havent 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
Ive 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.
ASUS
Open the ASUS Armoury Crate Software. Under the System Configuration section, toggle the GPU Mode setting between Discrete Graphics and Optimus as needed. A reboot will be required to complete the process.
Dell
Ive only had the Dell G15 5515 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.
HP
Open the OMEN Gaming Hub software, select the Graphics Switcher tab and swap between Hybrid and Discrete modes. A reboot will be required to complete the process.
MSI
Open the MSI Dragon Center software and select General Settings. Change the GPU Switch option between Discrete Graphics Mode or MSHybrid Graphics Mode (Optimus on) as needed. A reboot will be required to complete the process.
Lenovo
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.
Razer
Open the Razer Synapse software, go to the System menu and then the Performance tab, change the setting under GPU Mode. A reboot will be required to complete the process.
Tongfang (Eluktronics/XMG/Aftershock etc)
Open the Control Center software. Select General Settings, scroll down to Disable Nvidia Optimus and make the appropriate change. A reboot will be required to complete the process.
I still cant find it!
If in doubt, just look through the settings available through the laptops primary control center software. If theres 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.
