this might think that the dock itself is plugged into com port 1 and/or the IR port.<br />

i would check the bios to see if there are any settings pointed to com port 1 that should be changed or diabled.

I checked the device manager and nothing was using com port 1, so I then disabled it in the BIOS and I can now undock the laptop Thanks!

Whenever I try to undock my laptop for the port replicator I get an error message stating &quot;&nbsp;Cannot undock because com port 1 is in use&quot;. But there is nothing connected to the laptop besides a monitor and a usb keyboard and mouse. Any thoughts?
