Hi markdalern,
Welcome to Sony Community!
The SVE15112FXS has no supported drivers for Windows 10 therefore upgrading to this version will lead to certain limitations on the functionality of the laptop. Here is the link for more information about your laptop. I'm not really sure what you meant about "The drivers are all updated so that's not the problem" , were you talking about Windows 8.1 drivers (this is the latest that we have on the website) or Windows 10 (which we don't have yet)?
Regards,
Jen
