Microsoft Surface Devices Slow Down After Safety Firmware Update
Retailers who sell Microsoft Surface devices are facing complaints after owners discovered that the devices are slowing down due to an Intel speed issue.
Surface Pro 6 and Surface Book 2 devices are being throttled down to Pentium 2 speeds of 400 MHz, according to TechRepublic. The issue was immediately identified after a firmware update.
A Microsoft executive “We are aware of customers reporting a scenario with their Surface Books where CPU speeds are slowed”.
Initially designed as a safety issue the problem is apparently due to an Intel CPU flag named BD PROCHOT, which stands for bi-directional process hot.
The safety feature was designed to keep systems from overheating.
It can be set by any peripheral and may kick in even if the CPU is within its temperature limits if another component is becoming too hot.
The Surface Pro 6 runs at a minimum of 1.6 GHz while the Surface Book 2, which received an upgraded processor earlier this year, goes at 1.7 GHz. T
Digital Trends said that some owners of the Microsoft Surface devices said that removing the devices from their docks or AC adapters fixes the throttling problem, while some claim that the issue is caused by third-party antivirus software. However, there are some reports that even rebooting the systems do not set the processor speeds back to normal.
The increasing number of reports, as well as the recent firmware update, suggests at least a correlation between the feature and the affected 2-in-1 Surface devices, according to Tech Republic.
The true reason behind the throttling remains unconfirmed, and Microsoft has not shared the timeline for the release of the firmware update that will address the problem. In the meantime, affected Surface Pro 6 and Surface Book 2 owners may try the suggested solutions while waiting for the fix.
