Many Surface Pro 6 and Surface Book 2 models are suddenly being throttled

Microsoft's Surface Pro 6 and Surface Book 2 are operating into some crippling points, as processor (CPU) clock speeds throttle down incredibly low speeds, TechRepublic reports. The report comes from consumer complaints that point out their machines' Intel processors are slowing right down to as little as 400MHz.

For reference, the lowest-spec Floor Professional 6 runs an Intel Core i5-8250U processor, which usually clocks at 1.6GHz. That's four occasions quicker than the throttled velocity customers have experienced. And, that CPU can increase up to three.4Ghz, greater than eight occasions quicker than the lowered clock velocity.

The offender for the throttling is unclear, but the techniques in these situations are reporting a "BD PROCHOT" CPU flag that indicates that some element inside the pc is operating too scorching, which leads to the CPU throttling to decrease the temperatures inside the pc. Unfortunately, the throttling doesn't cease, as the 400MHz clock velocity stays for some even after shutting down and rebooting the computer.

But, which element?

Normally, you'd hope for the pc temperatures to go down and have CPU return to normal speeds after the element that raised the flag stops overheating. But, in this case, it's not clear that any element truly is overheating. 

Some customers did recommend the throttling stopped when disconnecting a Surface Dock or AC adapter, while others recommend antivirus software program could also be at fault. What would be the root of it all is a firmware replace. One was just lately released for the Surface Professional 6.

This wouldn't be the first time an replace induced points for Microsoft's machines. Only recently, Wi-Fi and Bluetooth drivers were hit with points, and the Windows 10 May 2019 update has caused problems for the Surface Book 2.

A Microsoft spokesperson advised TechRepublic, "We are conscious of some clients reporting a state of affairs with their Surface Books where CPU speeds are slowed. We're shortly working to deal with by way of a firmware replace."
