Hi folks,
First-time poster here.
Got a problem with an xb2000 expansion base and a compaq R3070US.

When the laptop is plugged into the base, it won't boot up. The fans and drive power up, but the laptop just sits there indefinitely with a black screen (doesn't even flash on power up).

After powering down (holding the power button for 5 seconds), and removing the laptop from the dock, the laptop then powers-up (on battery) with a "failed boot" message. After hitting F1 to get past that, the laptop will boot up, and will continue to work if it is plugged into the expansion while running (I know, not a good practicve, but it seems to work).

I am running XP with SP3. Any ideas why the laptop won't boot in the expansion base?

Oh yeah, during the "infinite wait", the built-in USB thumb-drive on the R3070 flashes on and off about once a second.

Thanks folks, E.

I'd remove the thumb drive, turn on bios expanded message and see what it says

cheers ...
