Windows 10: 100% CPU when laptop screen off AND mains power

I have a Thinkpad x230 and just installed Windows 10 Pro 64. Every time my display turns off AND the power cable is plugged the CPU goes to 100%.I've looked in Resource Monitor and it's "NT Kernel & System" which is responsible.I've seen similar questions and people have been advised it can be a virus..... it's not. I also doubt my drivers are wrong given how new the installation is.I think this is related to Windows services causing Windows to install updates/do lots of work in the background when screen is off and mains power plugged.Could someone please help advise how I can narr

Laptop with broken screen How much?

I would like suggestions and look in local stores. I dont wanna buy a laptop from someone online. Sorry. But could be a good idea if you asked him about the performance on older games. Gonna make a list ofall laptops people suggest me.

Remove the screen for space purpose here its small desk and if the screen is opened it will hide my 22 inches lcd

CPU is always forcing to 100%

So my cpu is always forcing itself to 100% for example with Microsoft edge open it forces edge to use 85% cpu to make the total up to 100%.

I've tried resetting my windows but only on my C drive which only really had windows on as I install the majority of my programs on another drive.

I'm using a 7700K.

Ive updated my motherboard drivers tried updating my gpu drivers.(1070)

I've messed around with the power settings im currently on balanced and have tried power saver.

On my resource monitor it says 104% cpu usage and the main two at the top are memory compression and system even after reset. and max frequency is 103%. Strangely however on CAM which I have to monitor my hardware it said that my usage was hovering around
20-30%.

Really no idea how to fix this any suggestions?
