Dynadock U3 - Satellite L500 sleep issues

[chippedliver]

I suspect there is no fix, but I've got the dynadock working fine under windows 7 x64.

The laptop monitor is set as off in dynadock and the display via HDMI is on the external monitor, however whenever I sleep the laptop and then wake it up the display is in a random state:

1) On the laptop only

2) Extended desktop on the dynadock monitor

3) Correctly on the dynadock monitor

I've updated the drivers, and checked every setting I can think of, but I cannot see a way to force windows to only ever display on the dynadock external monitor after waking from sleep.

I tried turning off power management for the USB and this didn't help if I manually put the computer to sleep. This also prevented to laptop from going to sleep.

I notice if I unplug and replug the dynadock it goes to the external monitor without issue, but this is annoying to do everytime it sleeps.

Anyone got any bright ideas.

Thanks
