White screen here too: happens the same way.
Almost as if there's some kind of power surge happening that knocks out the CPU and/or power-management driver when the Axim's docked?
It's happening, it's consistent and this is an expensive device. So... let's hope Dell does something soon, as it's getting tired. Along with the memory cards going AWOL.
UPDATE:
almost got a white screen just then with the Axim
undocked. The screen built very slowly, but I got it working. Here's my revised theory...
In effect, when the machine is off, there is a non-backlit white screen (which is normal). But then I think that when Axim gets switched on, it puts the backlight on, but then can't start the graphics for some reason... maybe a conflict with ActiveSync that stops it stone-dead?
