Hello Nhawk,

S4 is hibernation. The computer saves memory to storage and powers down most parts. S5 is full shutdown.
Reason for USB power still on:
There are BIOS settings overriding power - down for USB.

Have a nice day！

    Then I don’t understand the point of that selection in the BIOS. Why have something that says power down USB during S4/S5, but yet it has no effect

      The USB port is always powered, even when the computer is turned off.
      S4 and S5 are related to network wake-up.

      Then can we get a new addition in the BIOS to disable the USB ports when computer is powered off?
      My Gigabyte motherboard (Intel chipset) has the option to turn it on or off. Beelink SER8 should have it too.

        Hi there
        I am sorry ,currently .
        We don`t have such BIOS issued yet .
        please stay tuned with us .
        or try this .
        Please check the save energy in the device manager—universal serial bus controller–USB hub—properties–power management—check “Allow the computer to turn off the device to save power”

          I know the BIOS doesn’t have this feature now, but can you add it?
          As for Device manager:

          1. All USB devices already have "Allow the computer to turn off the device to save power” enabled
          2. When the computer is off, Windows Device manager has no effect, since Windows is NOT running

          Thanks for your support .We will provide feedback to the R&D.

          Nhawk How high is your CPU usage when idle? On my system (SER8 with 8745HS running Windows 10 LTSC) it never goes below 5%, which is far too high.

            Windows 11 24H2 shows 2% when idle (lowest I’ve seen so far) and that results in 2.38Ghz CPU speed (Task Mgr)
            Here’s a snapshot from CPU-Z:
            Image description

              The normal CPU usage when idle can vary depending on several factors such as the system configuration, background processes, and software running. Here’s an analysis of your situation:

              1. For the SER8 with 8745HS running Windows 10 LTSC

              2. Possible reasons for relatively high idle CPU usage (never below 5%)

                • Background services and processes: Windows 10 LTSC may have certain services or background processes that are constantly running and consuming CPU resources. Some of these could be related to system updates, antivirus software, or other installed applications that have background tasks. For example, if you have a cloud storage syncing application running in the background, it might be periodically checking for changes and using some CPU.
                • Driver issues: Outdated or incorrect device drivers can cause the CPU to work harder than necessary. For instance, an improper graphics driver might lead to inefficient rendering processes that consume additional CPU cycles even when the system is idle.
                • Power management settings: The power plan settings on your system could be configured in a way that causes the CPU to run at a higher frequency than needed when idle. This might be set to prioritize performance over energy savings, resulting in a higher CPU usage percentage.

              3. For Windows 11 24H2 showing 2% idle CPU usage

              4. Reasons for lower idle CPU usage

                • Optimized system architecture: Windows 11 has been designed with certain optimizations to reduce idle CPU usage. Its kernel and system processes are more efficiently managed, which can lead to lower resource consumption when the system is not under heavy load.
                • Improved power management: Windows 11 has better power management features that can more accurately adjust the CPU frequency based on the actual workload. This allows the CPU to run at a lower speed (such as the 2.38Ghz you observed in Task Manager) when idle, resulting in reduced CPU usage.
                • Enhanced background process handling: The operating system is better at suspending or minimizing the impact of unnecessary background processes when the system is idle, reducing their CPU consumption.

              3.To address the high idle CPU usage on your Windows 10 LTSC system, you could try the following steps:

              • Check background processes: Open the Task Manager and look for any unnecessary processes running in the background. Disable or uninstall any applications that you don’t need to be running all the time.
              • Update device drivers: Make sure all your device drivers, including those for the CPU, graphics card, and other peripherals, are up to date. You can do this through the device manufacturer’s website or using a driver update utility.
              • Adjust power plan settings: Try changing the power plan to a more energy-efficient one. In the Control Panel, go to “Power Options” and select a plan that prioritizes energy savings. This may cause the CPU to run at a lower frequency when idle, reducing the usage percentage.

              Nhawk 2% is also too much for idling. Which process is causing the CPU load for you?

              For me it is ‘system’ and frequent system interrupts.
              ‘system’ can be resolved to ntoskrnl.exe in the properties.

              If you investigate further with WPA from the Windows Performance Toolkit, you get the following files that seem to be related to the high load:
              msgpioclx.sys
              Wdf01000.sys
              ACPI.sys

              Another approach is
              powercfg /energy
              This also indicates too high processor load, missing standby modes and the missing pluton driver.

              It seems to be some kind of driver problem or a bad BIOS customisation.

                  Hi there
                  thanks for sharing .
                  please email us with BIOS version and SN pic if you need to update the BIOS.

                      Hi there
                      V29 is the latest BIOS . USB ports will stay on when shutting down the PC .
                      unless you pull out the plug.
