XPS 15 9560 i7 processor limited to 0.80 GHz

Turned on my laptop this morning and noticed it was running really slow.

Checked with Intel XTU to see what the problem was and noticed my laptop was Thermal Throttling and limited to 0.80 GHz. 

Called customer support, and after 90 minutes of running diagnostics, re-installing drivers, disabling programs that activate on startup, and reinstalling XTU, the processor is still limited to 0.80 GHz (although XTU no longer says it's thermal throttling). 

Support said they'd call back in 24-48 hours, but otherwise don't know how to fix the issue. 

I've added a picture of what XTU is showing. 

Any ideas on how to fix?

Is the system properly recognizing the AC adapter, or is it showing "unknown"?  F2 at powerup to check.

It seems to be showing up fine (not showing "unknown"). Problem persists whether AC is plugged in or not.

And you're using a 130W AC adapter?  Jump into the BIOS and check the Battery Information section to confirm that the system is in fact detecting a 130W power supply.  If you're powering the system via a dock attached to its USB-C/Thunderbolt port, a WD15 requires a 180W AC adapter to deliver 130W to the attached system, and a TB16 requires a 240W AC adapter to deliver 130W to the attached system.

Yes, I'm using the 130W AC adapter that came with the laptop. I'm not using a dock. When I checked in the BIOS it said 130W under the battery.

Try to remove the battery cable and power cable ,press the power button for at least 30 seconds. Then ,connect battery cable and start the laptop. I solved same problem like this.

Try to remove the battery cable and power cable ,then press the power button for at least 30 seconds. Finally ,connect all the cables and start your laptop. I solved same problem like this.
