On my Windows XP tablet, if I put an MP3 player into a USB port, does it charge the battery even when the pc is completely shut off?
I don't like to leave it plugged in to charge when I am using the pc since it keeps bonging (making a darn noise) every few seconds

There's a very easy way to tell - try it and see.

OK. Not smart am I?
I'll need to run the battery down and then try it!

I plugged my Cowon S9 into my HTPC which is plugged into the A/C outlet, but is currently off.

The Cowon's screen activated and is letting me know it is charging.

For a tablet / laptop, I don't know for sure...
