Microsoft Surface updates cause massive CPU throttling issues

Latest updates from Microsoft are not only affecting Windows 10 PCs, but Surface devices as well.

Surface devices are plagued by throttling problems

After almost a year since the first reports regarding a throttling problem appeared on forums, the problem re-surfaced up with the latest updates for Surface devices:

CPU speed drops down to 0.4 GHz when fully charged while plugged into the wall

And here’s the OPs screenshot: surface pro 6 throttling problem

The main devices affected are Surface Book 2 and Surface Pro 6. It seems that many Surface users are complaining about massive thermal throttling issues, with clock-speeds dropping to 400 MHz from 1.6 GHz.

The problem isn’t on Microsoft‘s end, as an Intel CPU flag called BD PROCHOT is causing it. This flag is related to peripherals and it allows the CPU to reduce its speeds in order to manage high system temperatures.

This is not the only problem affecting Surface devices, as recently a lot of Wi-fi issues were reported.

Microsoft is working on a fix

Microsoft has acknowledged the throttling problem an is working on a fix:

We are aware of some customers reporting a scenario with their Surface Books where CPU speeds are slowed. We are quickly working to address via a firmware update.

In the meantime, if your a Surface owner, you can try to install the Microsoft driver pack for your device or a full reset, as some users reported that they managed to fix the issue this way.
