Detailed description: It doesn’t happen that often but sometimes when the laptop is under load the CPU would throttle to 0.4 ghz and everything would run so slow. However the moment I unplug the charger it goes back to normal clock speeds. If I plug it again it either remains normal or eventually slows down again.

Is this a bug with the BIOS firmware or something? Currently I have BIOS version 307. This isn’t Windows 11 related as this also happened when the laptop was on Windows 10.


  • Hi there,

    does enter BIOS and load BIOS default setting again help?

    Thank you.

  • There was a new BIOS update recently so I will see if that solves the problem
