ProBook 450 with high CPU usage

[Expander77]

Many thanks to both of you! 😉 I hope the low CPU usage will remain in the future days!

I've installed the card reader driver as described above (driver version is 10.0.16299.29095). Now the PC works with NO high CPU usage after hibernate. The 5 months quest looks like is completed...

I dont have a Root port #12 nor do I have the Realtek card reader but I still have the issue.

@ju1c3: Can you post a screenshot of your Device Manager, with the opended System devices section? I suspect, that your Laptop has a SD Card reader.

I do not see card reader under system devices but under something like Memory (or storage) Technology Devices. As I do not have English version, I am just guessing English original name of the item:-) However, there is Realtek PCIE CardReader.

Also, under its properties, I can see following:  Slot PCI 11 ( bus PCI 4) so I am not sure it is connected to stated PCIe port #12 but update of driver for this CardReader definitely solved the issue.  In my case  it is version10.0.16299.21304 .

OK, so that explains that you might have different HW configuration than European laptops that I suppose were talked about here before mostly.
