Windows 10: 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

:)

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.

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.

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
