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

Ok, I think I've solved it through some scripting.

Unplugging and re-plugging the dock seems to always work in bring the display to the external monitor. Why oh why it doesn't work when you sleep/wake is beyond.

Anyway. Plugging/unplugging is the same as disabling/re-enabling the USB Composite Port. I also discovered that disabling/enabling the "Dynadock U3.0" under USB Display Adaptors has the same effect. The picture freezes when you disable and then you can re-enable via the laptop screen.

What I did is get devcon.exe for Windows 7 which allows you to manage devices from the command line.

I then dump the hwids and found the hwid for the "Dynadock U3.0" and put it in a script. i.e.

c:\devcon\devcon.exe disable "USB\VID_17E9&PID_4305&REV_0015&MI_00"
c:\devcon\devcon.exe enable "USB\VID_17E9&PID_4305&REV_0015&MI_00"

And this worked perfectly. If you get no matching device errors despite it finding the device then you have the wrong (old I suppose) version of devcon or didn't follow the install instructions. I tried copying it out of the cab file and kept getting the error. Following the instructions from microsoft worked.

I then followed these instructions to create a script to run when the computer wakes.

It makes wake up a fraction slow (20 seconds) but the external monitor is always there now or so it seems with limited testing.

Have you tried deleting

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\GraphicsDrivers\Connectivity

and

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\GraphicsDrivers\Configuration

? These are Windows' memory of the arrangements and settings for different monitor combinations you've chosen, and can sometimes get out of whack.

I just tried that (and rebooted). With the laptop setup with the external monitor (1680x1050) on HDMI I put the laptop to sleep. Wake it up and the laptop is in duplicated display mode on the laptop and the external monitor which I then have to correct.

It's going back to the shop. Very frustrating.
