Does anyone know if the Wizard is capable of charging its battery in a completely powered down state?

The battery on my Wizard (G4 Qtek 9100) was low today, but I just ignored it, the battery ended up running down completely to the point that the phone powered off, and would not turn back on when I tried to repower it. I connected the charger and left it sit for about half an hour, the charging light did not light, but I left it to charge. After the half hour I figured it should have gained enough charge to power on, so I tried and no luck. Luckily I have a charged spare battery, so I left the dead battery in the phone and wedged thin wires in between the dead battery contacts, and the phone's spring loaded contacts. I connected the + of the dead battery to the + of the spare, and the - of the dead to the - of the spare. Now both batteries are connected to the phone in parallel. This allowed me to power the phone up and boot it all the way up, where the charging indicator LED lit. I disconnected the spare battery, so that the dead battery can charge on its own. Sofar it looks like it is taking the charge.

I'm wondering if some of the people that have "bricked" phones might have run into the same problem that I have. If you have a "bricked" phone, try using another battery that you know has a charge.

go in registry with totalcommander or something similar to this key:

HKLM\Drivers\BuiltIn\usbfndrv

and change : EnableUsbCharging to '1'

press reset after u done this.
i had this several times with death battery and wouldnt charge on usb on the
computer but it did with the original charger.

Thanks, i'll give that a try. Just curious, do you know anything about how that works? I'm wondering how a registry key can controll a piece of hardware that has been completely powered down, and that windows mobile hasn't yet booted on.
