Surface 6 Pro CPU stuck @ 0,40 GHZ

When I leave my laptop for lunch break (as it is or before putting it in energy save mode) -- CPU is always on 0,40 GHZ when I come back.

I have 2 external monitors via the dock box connected.

So when I unplug the power supply from the laptop - CPU goes right up to normal speed.

Sometimes this stays ...  

Sometimes it falls back to 0,40 GHZ a minute later

Then only restart helps 

I have latest Windows 10 - all up to date.

Its there a solution for this problem??

Hello Paul Caspers (pcaspers),

                                                                                                                                                                                                                                           

Thank you for reaching out Surface Community. I think you are referring to the Clock speed is also called as clock rate. It is an indicator of its performance and how rapidly a CPU can process data (move individual bits). It measures how quickly a computer completes basic computations and operations. So if too many applications are running depending how much speed it needs to operate the GHz changes. If the CPU is practically at idle it will lower itself for power and heat purposes. Just make sure that the device is always completely up to date to avoid future issues.

No.

Its this what you describe above ... 

CPU stucks after a putting Surface in "energy saving mode" at 0,40 GHZ (see screen shot - here its just 3,20 GHZ)  - independing of what I do on the machine.

If I then remove the power cable from the Surface (connected to the Surface dock with 2 external monitors) CPU works normally again. When I reconnect the power cable - I'm back at 0.40 GHZ (mostly - sometimes it just keeps running normally)

Hi all,

me too, I'm having the same issue with a brand new Surface Pro 6! Our GPO will put my Surface to sleep after 30 mins of inactivity. So, when I come back from my lunch break, it's stuck and capped at 0,40GHz. Only a reboot or unplugging the damn thing will help. I am so very annoyed about this...

Please fix this.

If the Microsoft agent did even a little research before posting that response, he would have found many, many reports about this issue. Here are some examples:
