Hey guys. So here's my issue. My XPS 15 9550 (i5, 8gb, 256gb, 4k, 960m) is an awesome laptop and i love it. Whenever i am at home, i have it on the charger almost the entire time, unless im working around the house. Because i hate taking the bulky charger with me to class everyday (sometimes ill do some video editing and photoshop work between class's), i decided to buy an 87w macbook pro charger. That way i could always leave that in my bag and also use it to charge my OG pixel. However, whenever i run the laptop while charging off of the type c port, CPU performance tanks. It drops to nearly half of what it should be at. When the laptop is off the charger, the cpu runs fine. But when i charge it through the type c port, it gets halved, which seems kinda ironic. Any ideas? Also, it runs perfectly fine off the regular charger and I have the latest BIOS and haven't changed any bios settings and i have high performance selected when the CPU performance tanks.
