Fixed terrible coil whine in Early 2019 Razer Blade 15 advanced

I was about to return my 2060 Blade 15 to Best Buy, because the coil whine was so loud it was like the system was whistling sometimes. Before I did that, I decided to check the support page downloads, and discovered a bios update and another firmware fix for some controller or another. Good news! In the notes for those two updates, it specifically calls out motherboard noise, and after updating, coil whine is GONE!
