How to charge your external device when the computer is in sleep mode?

Original title: Charge external device while laptop sleeps

I know there is a way to charge an external device, such as a mp3 player while the laptop hibernates/sleeps. I accidentally turned it off one day when prompted and I cannot find it since.

Please help.

Thank you in advance.

Hi wavelily,


Does your external device uses a firewire port or USB port?


Here are the steps to get your external device (USB) charged even when the computer is in sleep mode

a.    Click Start -> in the start search field type: Device Manager, press enter.

If you are prompted for access either press continue or supply the necessary username and password.

b.    When Device Manager opens, expand the Universal Serial Bus controllers category.

c.    Here you will see several USB Root Hub listings, for each right-click and select Properties.

d.    In the properties window, click Power Management.

e.    Uncheck ‘Allow the computer to turn off this device to save power’, click OK.


Hope this information is helpful and let me know if you need any further assistance.
