USB Ports Still Powered in Sleep Mode? Here’s How to Fix It

USB devices still draw power from your laptop, even in sleep mode. Here’s how to change that.

I use my laptop pretty much like a desktop recording studio. It sits in my basement with all manner of USB devices plugged into it, including a USB audio interface, a USB midi controller, and a USB hub that has my mouse plugged into it. One thing that really bugs me about this set up is that when I put my laptop to sleep, all these USB devices remain powered on. Realistically, this isn’t a big deal. The amount of electricity it’s using is probably minimal. But it gives me anxiety to see that USB audio interface with its flashing light, indicating that it’s powered-on but can’t connect to my computer. If this laptop were somewhere other than my basement—say in the family room or in a dorm room—I can see how a tabletop full of dumb flashing USB devices could be even more annoying.

Short of shutting down my computer entirely each time I leave the room or unplugging the USB devices, I hadn’t been able to find a fix for this. Keeping USB ports powered while a computer is in sleep mode is the intended Windows 10 behavior.

Long story short, what fixed my problem with the USB devices staying powered was setting up my laptop to hibernate instead of sleep. Not a perfect solution, but it works for me. Read on for more details.

How to Power Off USB Ports when Laptop is in Hibernate

First, let me go over a few things that did not work for me. There are a number of Windows 10 settings that seem to relate to how USB ports are powered and when, but they all ended up being dead ends for me.

In the Advanced Power Options menu, there’s an option that lets you enable or disable USB selective suspend. This option lets your computer put USB ports into a low power state during sleep, rather than turning them off completely. Unfortunately, enabling or disabling this feature had no effect for me.

In Device Manager, if you go into the properties of a USB device, there’s a Power Management tab with an option that says “Allow the computer to turn off this device to save power.” Seems promising, but again, changing this setting didn’t help my cause.

I saw some suggestions in forums and Q&A sites about fiddling with BIOS settings, but I wasn’t about to do that (I also heard it doesn’t work).

In the end, what did the trick was changing my laptop’s behavior so I go into hibernate mode rather than sleep mode when I close the lid.

“But wait,” you might say. “There is no hibernate mode in Windows 10!”

Oh, but there is. Check out Brian’s article: How to Enable Hibernate Mode in Windows 10

Now, when I close my laptop lid and walk away, all the lights go out on my USB devices. Much better.

Of course, there are some pros and cons of sleep vs. hibernate. But for me, the only pro I care about is getting rid of those annoying blinking lights.

Do you use sleep or hibernate in Windows 10? Tell me why in the comments.

  1. Do keep in mind that this might decrease the overall lifespan of your SSD if you have one. Even if just for a little. I personally rely on a USB hub with power switches so that I can turn off certain USB devices easily.
