Is there an effective way to contact Nokia?

I'd like to see if they could diagnose this problem remotely before I mail it off to them.

BTW, I also tried bringing it up in "target" mode by holding down the "swap" key while powering it on.

I get a little blue "USB" icon in the upper-right corner for a split-second, and then it goes away.

My N810 just sits there with the blue NOKIA on a white background.
