UPDATE: This has been solved. Resolution can be found in this thread. New Laptop (Dell XPS 15 9550) is currently stuck at 800mhz with windows reporting a maximum CPU usage of 28%. Any ideas why? CPU: I7-7700HQ (2.8ghz) Memory: 16gb HDD: M.2 512gb OS: Windows 10 (latest updates) Latest BIOS installed. It looks as though the multiplier is currently stuck at 8, however I have been unable to make any changes. The BIOS is typically useless, very little information regarding processor clock speed etc. I have reset the BIOS to factory defaults however the problem still persists. I honestly think this may be a problem with Windows power management however, for the life of me I cannot find the relevant options. Any help would be greatly appreciated.
