T400 on advanced mini dock wakes up then switches to 640x480

2008-11-24, 9:02 AM

Everything works fine. I'm using Windows XP and a DVI connection from the dock to the monitor. The problem I see is when I need to wake the machine by pushing the power button on the dock (touching a keyboard key isn't enough). The monitor comes back fine for a few seconds, then switches to 640x480 which shows me an unusable section of the screen in extremely poor resolution. I've got to reboot to get rid of it.  I've seen at least similar posts around forums but no real solutions. Anyone work through something like this ? The T400 is just a few months old.

 

Strangely enough, when I was first getting the external monitor working, I fond it hard to get the resolution set so that the resolution setting would work. It always seemed to want to revert back to 640x480 on the external monitor. Not sure why. It eventually stayed on the resolution I set but obviously not very well.

I should add that in my display settings, What I THOUGHT I needed to do was set the #1 monitor resolution to 1440x900 which is the laptop screen resolution and set the #2 monitor resolution to 1680x1050 which is the 22" external monitor resolution but windows just resets the #2 one to 640x480 so perhaps this is my own configuration problem but now I'm confused as to how the setup should look.

Have you checked the system eventlog for driver problems? Use the utility called "Event Viewer" by START/Run... and then type "eventvwr" to do so.

 

Under Vista, there have been reports about driver problems with your configuration. See here.

Thanks ! Looks very close to what I'm seeing (except for the Vista part). I'll read through it and subscribe.
