XPS 15 9560, CPU/GPU, not working at full, solved

As far as i was able to find there are two funky fixes to this issue:

1. https://www.reddit.com/r/Dell/comments/5uh6wo/fixing_your_dell_xps_cpu_stuck_at_minimum/ 

I had the same issue, the CPU was stuck at 800Mhz on Windows 10 and on Ubuntu.I found a fix without having to open the bottom lid and removing the battery:

Disconnect the power supply and use the laptop until the battery is empty.

The laptop shut down when the battery was almost empty, I restarted it again to really drain the battery. At 0% battery load I pressed the power button several times until nothing happened anymore. After waiting a minute I reconnected the power supply, hold the power button down for some seconds and started the laptop again. That solved it! The CPU now runs at 3.12 GHz as expected.

Has anyone found a proper solution for this? I am facing the same issue on my Dell XPS 15 9560 with the i7-7700HQ, the core frequency is stuck at 0.8GHz no matter the power option, or load. I tried updating every driver, and have the latest BIOS update, I tried changing and resetting the C-state and UEFI options and nothing changed. The system is passing all the tests Dell and Intel utility tools can possibly run. I tried booting in Safe Mode and noticed that the core frequency went back to 2.81ghz, which is normal, it's just when I boot into windows normally that it gets stuck again. I tried disconnecting the battery and reconnecting it, as some suggested it may be to power delivery problems, but it was still stuck to the low frequency plugged or unplugged, and connected to the power or not.

The only work around for me was to try ThrottleStop, which many other threads recommended, and it's the only option that seemed to work. Specifically, you need to uncheck the BD PROCHOT option, BD PROCHOT stands for bi-directional processor hot. It is basically a signal line going to your Intel CPU. When a CPU receives a signal on this line, it is forced to immediately start throttling. It does this by dropping the CPU multiplier down to 8 so the CPU will be stuck at 800 MHz. It's a bad sensor in the motherboard apparently. If you uncheck the BD ProcHot option, you might see that the processor frequency will shoot up to the it's max all the time, so if you don't want that, you can check the Disable Turbo option, which will bring it down to it's regular base frequency, in my case 2.81ghz. 
I just wanted to see if more people are still facing this issue, and if it's truly a hardware issue relating to the sensor on the motherboard, or if some new update fixed anything. I hope Dell at least acknowledges us, because it's been very frustrating dealing with this issue personally, and seeing many others online facing the same problem.
