Immediately when I plug in my charger my CPU will downthrottle and stay at 798MHz according to RealTemp. That's with balanced mode or high performance mode running as power plans. I have gone into the Advanced Power Saving Options menu's for both settings and changed the Processing Power Management submenu's to running 100% while plugged in. Still no change. No clue what to do from here. Any suggestions? This is a Acer laptop running Windows 8.1 with an Intel i5 4210u
