@Nee24 Your laptop only has one GPU, so it doesn't matter whether the graphics hybrid function is supported. I don't know enough about that feature to know whether the driver is too old for it, or there's a hardware requirement your laptop doesn't meet, or it's just automatically disabled when there's a single GPU, but I do know your laptop can't use it.
It is worth updating the graphics driver though. In general, it's best to use the driver provided by a laptop manufacturer unless you find a specific reason not to: an error that points to the driver and isn't fixed by reinstalling, or a new feature you want or need. When the problem might be the driver or might be something else, it's typically better to address that potential something else first. Since there's no direct evidence that the driver is the problem, I wanted you to update your other software first and also try addressing the errors you are seeing.
However, since none of that helped, it's time to try the newest driver from Intel, which you can get here:

Run the installer as an admin: right-click the download and select "Run as administrator." If you see the option to do a clean install, choose that. Either way, restart after installing and before trying to play.
If you get an error when trying to install the driver, that's likely Dell software blocking any drivers not provided by Dell; some manufacturers do this for some models. There's a way around it; let me know if you're interested.
As for your mother's laptop, you could absolutely sign into your account in the EA App and download your game and DLC there. Your saves wouldn't be present, but those are easy enough to transfer, and everything you've bought (or redeemed for free) should be available.
