Just change that, and your device should charge. I also put my computer to sleep manually if I know I am going to be taking a break for more than 15 minutes.

If after following all of the previous steps your device won’t charge, it’s because you are using MTP or File Transfer on your device instead of using the charging connection. I have my computer set to automatically sleep if it is idle for 15 minutes and my screen dims after 5 minutes.
My Device Won’t Charge After Following the Guide If you are the administrator and can see the tab, the only option you should see will say “Allow the computer to turn off this device to save power.” All you need to do is uncheck this, and next time you need to charge your device while your laptop is in sleep mode, you can easily do so. The last option you will see is “USB Root Hub ” right-click on it and select “Properties.”Īfter you have done this, you should be able to see a tab called “Power Management.” If you can’t see it, that means you are signed on as a regular user without administrative options, and you won’t be able to change anything.
