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

0 3

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

For reference, the lowest-spec Surface Pro 6 runs an Intel Core i5-8250U processor, which usually clocks at 1.6GHz. That’s 4 instances quicker than the throttled pace customers have skilled. And, that CPU can increase as much as 3.4Ghz, greater than eight instances quicker than the decreased clock pace.

The perpetrator for the throttling is unclear, however the techniques in these situations are reporting a “BD PROCHOT” CPU flag that signifies that some element inside the pc is working too sizzling, which ends up in the CPU throttling to lower the temperatures inside the pc. Unfortunately, the throttling would not cease, because the 400MHz clock pace stays for some even after shutting down and rebooting the pc.

But, which element?

Normally, you’d hope for the pc temperatures to go down and have CPU return to regular speeds after the element that raised the flag stops overheating. But, on this case, it isn’t clear that any element really is overheating. 

Some customers did counsel the throttling stopped when disconnecting a Surface Dock or AC adapter, whereas others counsel antivirus software program could also be at fault. What often is the root of all of it is a firmware replace. One was not too long ago launched for the Surface Pro 6.

This would not be the primary time an replace precipitated points for Microsoft’s machines. Just not too long ago, 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 instructed TechRepublic, “We are conscious of some prospects reporting a state of affairs with their Surface Books the place CPU speeds are slowed. We are rapidly working to deal with through a firmware replace.”
