If you’re like me or most other people I know, your laptop doubles as a laptop and a power house. It powers all your other devices, sometimes I carry my laptop about solely for that purpose. Whatever happened to power banks? The thing is, I forget to charge my power banks, but I never forget to charge my laptop. So there you have it.
The problem with charging your devices with your laptop is that, when the laptop is not plugged in and all you’re doing is charge your devices, the laptop has to stay on, fully on and this wastes power. Power that could have gone into further charging my army of mini gadgets.
Until recently, I discovered that with a few tweaks here and there I could charge even after my PC goes to sleep. Heck if you’re lucky you can even charge when your laptop shuts down. I’ll show you how to do this in a few moments.
First take a look at your USB ports to see if there’s any yellow coloured one. If there is, you may not need to perform this tweak because they perform that function already. If there isn’t, just to be sure, shut down your laptop and try charging, then put it to sleep and try charging. No charge? No problem.
To change your USB port’s power settings, you need to open the device manager. In Windows 10, you do that by right-clicking Start and selectingDevice Manager.
Click on the section that says Universal Serial Bus Controllers. When the listing expands, look for the items marked USB Root Hub. You may see one or several labeled USB Root Hub (xHCI). Those are typically your USB 3.0 ports. Right-click one of the hubs and select Properties. Click the Power Management tab and uncheck Allow the computer to turn off this device to save power. Click OK and you’re done.
Now, when the PC is in sleep mode, you’ll still be able to charge your devices. You may not want to change this setting on all your USB hubs and instead go with just one or two. There may also be some situations where even after tweaking settings your USB ports won’t supply power. More often that not, however, changing these settings will do the trick.
