Question Dell Laptop high CPU usage with dock

[alexous]

Giissmo 9-in-1 docking station
Hi there, I have a Dell Inspiron 3501 laptop and I use it with this docking station. On the hub I connected two monitors, a webcam and the mouse receiver. I observe consistently that the laptop fan is working and also the CPU usage is very high. OS is Windows 11 x64 22H2 and the hub requires a Silicon Motion driver which is the latest. Any solution? Perhaps modify something in power settings?

Have you seen if your laptop is pending any BIOS updates? Might also want to see if your OS is pending any updates. Do you have any items in Device Manager flagged with a yellow exclamation mark?

1) Are you sure that it's the dock causing the high CPU usage?
2) You can try disabling PreFetch in Windows and see if that helps. Instructions can be found HERE.

No BIOS updates (it's latest version) and no (for Device Manager)

1) I don't know that, but how can I get to know it?
2) I did it and if there is difference I will reply here. I need to monitor for some time

Does the issue happen when you have the dock unplugged? If you're not sure, unplug it and run it with just the LCD and other stuff and none of the extras provided by the dock and see if the issue continues.
1) If does continue, it is something other than the dock itself causing the CPU usage to stay high.

According to the link you provided for the docking station I noticed this line:

Before using USB C Docking Station, you need the first download and install the program "Siliconmotion" on your computer, and make sure that the program is running when you use Docking Station

See if that particular program is the source of your high CPU usage. Bring up task manager and look at the CPU usage and whatever program is causing it to be high at the time.

It happens usually when I go away from the laptop and there is a screensaver on the screen. It happens also while in videocalls (ie MS Teams). I am running a VPN service all the time by the way and I think that the VPN drags a lot of CPU...

That can certainly increase the load of things.
