Low Clock Speed

My Asus X560UD's CPU (i5-8250U) clock speed is stuck on 0.40GHz. It doesn't go way beyond that.

 

I tried turning it off and on again, temporarily disabling Virtualization, reverting to a restore point, adjusting processor power, and re-installing Intel DPST and none worked.

 

This happened while it was running SimCity. I accessed a file in the laptop over LAN when the frame rate suddenly plummeted to 10fps and later finding out the CPU clock speed is way ridiculously low.

 

Anything I can do? I'd like to avoid resetting to factory default.

I know. But that's how far an Aida64 stress test can bring it.

 

After running the laptop for a few minutes, the clock speed rose to stable 3.34GHz while plugged in. It's good but not normal as I'd normally see 1.00GHz on idle. Running it on battery brings it to 0.80GHz and adjusts depending on system load. Restarting the laptop, however, reverts the system back to 0.40GHz. It takes a few minutes for it to run at 3.34GHz again.
