Hold down SYMB, connect the USB, and chances are it will power up. Your battery is probably completely drained down. Leave it plugged for a while and the battery should charge up some.

Tim, the battery is fully charged (checked with a multimeter). Even with usb plugged (with or without battery inserted) the SYMB-Reset does nothing.
An USB power checker shows that when I connect the calculator (with battery) to the cable, no current flows (or a current less than 0.005A).
The only, slight, sign of life I get from the calculator, is if I remove the battery completely, and then insert the USB power cable: then for about 1/10th of a second, the screen lights up (with no discernible image). But even then, having SYMB or other keys depressed does nothing.
I opened the calculator and there's no visible damage. All the connectors and cables are tight.

I don't know about calling support... I bought the calculator in the US but I'm in Italy now, and besides, I think I lost the receipt. I suppose I'll start looking for a good-condition, used one. But if you want it to have it looked at, if someone at the lab is interested, I can send it to you.
