Make sure to directly check the BIOS configuration settings for your particular computer model. As mentioned earlier, some laptops come with BIOS settings related to graphics switching, like "Discrete," "Switchable," or "Hybrid." To do this, access your BIOS, search for your computer model on the Dell website, and follow the provided instructions for BIOS setup.
Just a heads-up, though: tweaking BIOS settings can be risky, so proceed with caution.
