Is it possible to recharge a cell phone's battery even if USB is disabled or blocked on the system?

Blocked and disabled are not the same thing to my understanding. Blocked means the USB port I/O is restricted but the port still has power, in which case it will able to charge your phone. Disabled means the USB port has no power whatsover, in which case it cannot charge anything.

How are the mice and keyboard connected? Via a PS2 port? You could take a PS2 to USB adapter and charge your phone that way. If you dont have one, most IT geeks have them lying around. I just checked and I have 10 sitting in a box. :P

If the USB port on computer is disabled, then it will not charge.

  • I was surprised by this answer, but I looked it up. You are right. – Keltari Aug 22 '11 at 07:57
  • The reason is basically because it is not getting any power though the mobo. This means no data, and no power to charge anything. – soandos Aug 22 '11 at 07:58
  • I would have thought they would still be powered, just not passing date. You learn something new every day. – Keltari Aug 22 '11 at 07:59
  • If I want something disabled, why would I want to keep it powered? – soandos Aug 22 '11 at 08:02
  • the confusion is understandable. I also would have thought the mobo would keep the port powered only. Useful knowledge. – Sirex Aug 22 '11 at 08:32

Yes, it is possible to charge even though the USB is blocked. Most of the time, it is the data ports that are blocked leaving the power ports open for power supply.
