Sandy, the computer will need to be powered on for it to charge the device. Unless of course the usb port you are using supports charging while off. I have a dell laptop that has this functionality on just one port. It's a new function from what I remember.

Hi, Can anyone tell me, if one is charging a device using the usb connection and the PC or Laptop, both of which are plugged into the mains, do you need to leave the pc or laptop booted up in order to charge the device? Thanks, Sandy. =========================================================== The vicsireland mailing list To unsubscribe at any time send a mail to: vicsireland-request@xxxxxxxxxxxxx with the word "unsubscribe", without the quotes in the subject of the message.
