AI Thread Summary
Charging a phone through USB without a functioning outlet charger can be problematic. While some phones can charge via USB without being recognized by the computer, others require recognition for charging to occur. The ability to charge depends on the phone's design; not all phones support charging through a USB data link. Additionally, the charging and battery control circuits may be located in the charger rather than the phone itself. Using generic USB-to-charger adapters can pose risks, as they may deliver unregulated power, potentially damaging the phone. For certain models, like the Motorola Razr, specific software or drivers must be installed on the computer for USB charging to work effectively. Caution is advised when dealing with Li-Poly batteries due to safety concerns, as improper charging can lead to dangerous situations.

Ok, so my phone died :( and my outlet charger is broken so I charge it thru the USB. Does my computer have to actually recognize my phone in order for it to start charging it?

I've had it hooked for an hour now ... but it still hasn't turned on even for a second.

If your phone has a Li-Poly battery do NOT plug it into any old place. The battery can explode and burn your house down. Not kidding, Li-Po batterys are not a joke.
 
yes this will work
 
Grr ... I think it does need to recognize it :( it's still dead.
 
It doesn't have to recognise it - but it does have to be able to charge through USB!
Not all phones can even though they have a USB data link.
Sometimes the charging / battery control circuits are in the charger rather than the phone. Another problem is that the USB->charger plug adaptors just put 5V into the phone with no control - I have ruined phones with these before.
