It's going to be the laptop. Best example I can think to give doesn't match this exactly but it's pretty close.
An iPad draws a lot more juice than an iPhone. An iPhone charger provides 5v, 1 amp, an iPad charger is 10v, 2 amps. If you hook an iPad to an iPhone charger it provides enough juice to run the device, but not enough to charge it unless you completely power down (not just lock/sleep) the device.
Your USB ports might not be putting out enough juice to power and charge your phone simultaneously, that's what it sounds like to me. Outside of a cable just not working at all I've never heard of one reducing current so that doesn't seem likely at all. --- Every time I try to go where I really wanna be it's already where I am, 'cuz I'm already there XBL, PSN, Steam, Origin, BSN, GFAQs, MC: PhilOnDez
It could be the laptop. I once had a laptop that couldn't power a USB-powered external disk (it only managed to push the LED), while all other laptops could. --- MageofBlood391 posted... GameFAQs: Because if all else fails, you can always argue semantics.
