Bricked?

[Christopher Heiny]

I think I've done something awful to my Neo.  After running the battery 
flat last Wednesday, I plugged it into the USB wall charger and left on 
a long weekend.

Co-workers report that for a while on Wednesday and Thursday the Neo was 
intermittently lighting up and showing the boot splash screen.  This 
behavior is not seen any more.

In fact, no behavior at all is seen any more.  There's no response to 
the power button.

We've switched batteries, and changed from the wall charger to a USB 
port, but the problem remains.

I'm not much of hardware guy, so I'm not sure where to go next.  Any 
suggestions?  Or have I very stupidly fried it?

                                    Thanks,
                                        Chris
