If it helps, all our portables have PCMCIA controllers as discussed before somewhere in this forum as far as I recall, so I've done a simple query to show the portables:
SELECT DISTINCT dbo.tblPCMCIAController.Computername, dbo.tblPCMCIAController.Lastchanged, dbo.tblComputers.Username
FROM dbo.tblPCMCIAController INNER JOIN
dbo.tblComputers ON dbo.tblPCMCIAController.Computername = dbo.tblComputers.Computername
