dell xps15 9560 cpu stuck at 0,78GHZ. PLEASE HELP!!!!!!!!!!

HI, recently i format my computer , and now i noticed that the cpu stucks at 0,78ghz. And this correspond betewen 2% at 10% of the processor full power. The other thing that seems oddly is the fact of the thermal throtlling its always on , even when the temperatures are lower than 40C.

@dloureiro  glad to hear that your power source is ok, but sad to hear that it means the underlying cause still isn't clear.  There's a thread here about Latitude E7440s getting stuck at 0.8 GHz where owners of other system models have mentioned having the same experience.  There are a few different fixes, although some of them would be trickier or even inapplicable on the XPS 15.  For example, disconnecting and reconnecting the battery is a bit more difficult, and removing the screw in a particular area of the keyboard is likely specific to the E7440.  Using Throttlestop might work, but I've never used it personally so I can't comment on reliability or any risks that might arise from going that route.

@dloureiro  go into your BIOS Setup and go to the Battery Information section.  Below the battery icon, the system will indicate the detected wattage of the attached power source.  The XPS 15 is designed for a 130W power source, so make sure it shows at least 130W.  If it shows "Unknown", there might be a problem with your power adapter, and when the system can't identify the wattage of a power source, it operates using as little power as it can, which includes throttling performance significantly.  If it shows a wattage number that's less than 130W, make sure you're using a 130W power source.


hi @jphughan  thanks for your reply. 

I just went now to bios setup and everything is ok
