Only comes on when i plug in the usb cable to charge and only for about 5 seconds then it goes out.
Tried the usual removing the battery left it for an hour or so and stuck it back in - nada.
Tried new battery.
Tried Apploader and JL commander but can't connect as I'm getting the "Usb device not recognised" every few minutes whilst the computer tries to identify the Blackberry!
Cant even get to the USB-PIN:UNKNOWN stage so at a loss as to whether it is permanently nuked or just stuck in a power diagnostics loop.
The screen is dead but displays the power dead/battery symbol once in a while which leads me to think that it isnt completely dead and may just be a faulty usb port but without the ability to charge the battery as i dont have a standalone charger unable to proceed.
No it was a cheapo from Hong Kong but i've tried a new battery from our spares cupboard at work sup3p3lied by Rim and its the same.
I have borrowed a mains charger will try that next but sure its the usb socket!
I think it may be a case of pulling the usb cable without stopping the port which although microsoft says cant damage the usb device anymore i am doubtful - you should really always eject the device but sometimes being lazy doesnt help!
The blackberry if plugged into the AC USB charger when pulled does not cause any issues so I doubt the Data cable connected to the PC would cause any issues. You may be correct in that the connector is defective.

Blackberry must be buffered then i guess im clutching at straws but for sure you can still damage usb peripherals by yanking them from the usb port - i saw a user do it with a cheap memory stick last week!
