I have a Surface Pro 5 with i7, 16GB memory and a 1TB SSD. It only runs Microsoft software, e.g., Edge, Teams, Office apps, etc.
Whether plugged into the power or not it runs very hot and becomes unusable (screen still visible, mouse can move erratically) and. In the task manager I can see that the CPU is running low (<50%). It is most frustrating when on a Teams meeting and everything just stops. I've tried everything over the past few months per advice in these forums, but nothing works.
I do have a laptop fan device that I can lean the Surface Pro on whilst at my desk which is sufficient to keep it cool and running. When I travel or move away from my desk the Surface quickly becomes unusable.
I really like my Surface but if this cannot be resolved I will be looking to swap to another device brand.
Cheers
Brad
