  1. PCI Express Root Port


    Hi,


    I built my windows desktop a few months ago and have never been able to get it to sleep or hibernate.

    I ran the powercfg -lastwake command and received this back:


    C:\Windows\system32>powercfg -lastwake

    Wake History Count - 1

    Wake History [0]

    Wake Source Count - 1

    Wake Source [0]

    Type: Device

    Instance Path: PCI\VEN_1022&DEV_1453&SUBSYS_14531022&REV_00\3&11583659&0&0B

    Friendly Name:

    Description: PCI Express Root Port

    Manufacturer: (Standard system devices)


    C:\Windows\system32>



    I have adjusted power management settings, disconnected all peripherals etc and none of it has made a difference.


    I had this issue before putting in a usb pcie expansion slot. My other pcie connected components are my GPU.


    Does anyone have any tips on what to change to be able to get my computer to sleep?

    These are my components:
    Mobo Gigabyte B450 aorus pro wifi
    GPU Gigabyte 1080 windforce

    CPU Ryzen 2600x

    RAM Trident Z 3200

    Boot drive m.2 970 evo

    Second drive m.2 860 evo


    Thanks PCI Express Root Port :)

    :)

  3. Windows 10 PCI Express Root complex Code 28

    Hello Patricia,

    Just curious how is it that you found out that the device installed on the PCI Express Root Complex is the drop / fall sensor, I'm having the same issue and have no clue how to determine what is this "unknown device" that installed on the PCI Express Root
    Complex.

    PCI Root Complex uninstalled

    Hi,

    Thank you for posting your query in Microsoft Community.

    I understand your concern regarding the issue that you are facing.

    In a PCI Express (PCIe) system, a root complex device connects the processor and memory subsystem to the PCI Express switch fabric composed of one or more switch devices.



    Please reply to these questions:



    1. What is the make and model of the mouse?

    2. Have you tried with different USB ports?

    Let us try the following methods:



    PCI Express Root Complex issue:

    Method 1: It is a component of the motherboard; update the chipset drivers from the manufacturer’s website and see if that helps.



    USB mouse issue:



    Method 2: Windows has a built-in troubleshooter to check and fix issues with Hardware and Devices. I would suggest you to run this troubleshooter to check if the issue is with your Devices.

    Refer these steps:

    1. Press Windows key +X, select Control panel

    2. Change the view by option on the top right to Large icons

    3. Click on troubleshooting and click on the view all option on the left panel

    4. Run the Hardware and Devices



    Method 3: Try with different USB ports, and see if that helps.



    Method 4: Update the mouse drivers, and see if that helps.

    Follow the steps below to update drivers.

    1. Press Windows key + X and click on Device Manager.

    2. Expand Keyboards, Mice and other pointing devices.

    3. Right click on the driver and select Update Driver Software.

    Hope this information helps. Do reply, if you need further assistance, we will be happy to help you.
