USB-C Monitors Disconnecting

[k02]

My dual USB-C monitors constantly disconnect and reconnect, particularly when my laptop is under heavy load. I have tried multiple suggestions from this forum, including adjusting Power Management settings. I looked into updating my BIOS, but my OS (Windows 11) is not listed. My laptop and monitors are only 1-2 years old. Any other suggestions?

Hi @k02

Welcome to the HP Support Community. We are here to help you with it.

Solution 1: Reinstall the Universal Serial Bus Controllers Driver

A driver issue can be the reason for USB devices disconnecting and reconnecting Windows 10. To solve a driver issue, you can reinstall the USB or Universal Serial Bus controllers driver in Drive Manager.

To do this job, you need to follow these steps:

Step 1: Press the Windows + X keys simultaneously and then click on the M key to open Device Manager.

Step 2: In the Device Manager window, please go to find the Universal Serial Bus controllers option and expand it. Then, you need to look for the listing which is related to your USB driver.

Usually, there are two different situations:

• If it is a regular USB drive, it will be listed as a USB Massive Storage Device.
• If USB 3.0 keeps disconnecting Windows 10/8/7, you need to look for USB 3.0 Extensible Host Controller.

Here, take the USB 3.0 device as an example.

Right-click on the Standard USB 3.0 eXtensible Host Controller option and choose the Uninstall option to uninstall it.

When the uninstallation process ends, you need to reboot your computer to allow Windows to reinstall the drivers automatically.

Then, go to check whether USB ports keep disconnecting and reconnecting Windows 10 issue is solved.

Solution 2: Turn off the Power Saving Option

Some users say that they solve USB keeps disconnecting and reconnecting issues by turning off the power option. If solution 1 doesn’t work, you can try this way to get rid of the issue.

Here we will show you this solution with its detailed steps as follows:

Take the USB 3.0 device as an example.

Step 1: You still need to enter the Device Manager interface and find the Universal Serial Bus controllers option.

Step 2: Right-click on the Standard USB 3.0 eXtensible Host Controller option and choose Properties from the pop-out list. Then, switch to the Power Management section. Next, uncheck the Allow the computer to turn off this device to save power option and press OK to keep the change.

By doing this, it will make sure that the system will not turn off the USB device when you are using the computer but don’t use the USB device for some time

Hope this helps! Keep me posted.
