I am running Windows 10 Version 3 Build 18363 and my processor is an Intel(R) Core(TM) i7-8705G CPU 3.10GHz, 3096 Mhz, 4 Core(s), 8 Logical Processor(s). Integrated: Intel(R) HD Graphics 630 25.20.100.6615 ()ĭiscrete: Radeon RX Vega M GL Graphics 8.2 () You may remember some of our January power experiments we mentioned in Build 15002’s release notes. Screenshot 2: CPU Usage graph showing top at 50% consistently even though computer is sluggish With Power Throttling, when background work is running, Windows places the CPU in its most energy efficient operating modes work gets done, but the minimal possible battery is spent on that work. Screenshot 1: Sample process using "high power" while only 40% or so CPU Screenshots (check captions for number label): Used the computer with the power cable plugged in. What I have tried (not a comprehensive list):Ĭhecking power management plans and current CPU usage (everything is on maximum performance) Do you have any suggestions or ideas regarding potential fixes? Also, if there is any way to fix the issue where dwm uses the integrated GPU, please let me know. I believe that this is still a power issue with the CPU, especially since the clock speed seems throttled. I know that Minecraft typically uses system resources inefficiently, but it still appears that CPU usage is getting cut off at around 50% most of the time even when the game or other task is unresponsive due to slow processing. I have rarely seen my CPU usage go above 50% for most tasks, including gaming with stuff like Minecraft. Nevertheless, here is my current problem (previous text still important):
This generally fixed my issue, although it still locks the clock speed at some points because the Desktop Windows Manager (dwm.exe) still sometimes uses the integrated GPU excessively. I found that the times where the clock speed would lock corresponded to a usage increase in the integrated GPU so I switched most of my apps to my discrete GPU (manually because there was no BIOS option to use the discrete GPU as the default -_-). First, I had an issue where the clock speed would lock at exactly 25% CPU usage and 25% clock speed (0.77 GHz). I have owned my HP Spectre x360 15-ch0xx for almost a year at this point and have experienced numerous issues related to CPU usage which seem to be based on a lack of power to the CPU (bad motherboard?).
