Hi Char! Yes this has been pretty standard on laptops since at least by
the late 90's. And yes the monitor hotkey works fine, so no problem there.
Oh aside note: If you are ever on a Windows system and Windows or the
hotkey won't let you switch monitors, close all video players and try
again. As it had taken me years to figure that one out.
Anyway you give me some ideas. Under Screen resolution I told it to
always use the external monitor. And that behavior of automatically
switching screens when the lid was opened stopped.
So I rebooted to see if it would stick. Nope, Windows 7 defaults back to
the original settings once again. And I tried it again and now I can't
get it to stick anymore.
I don't often lift the lid while is it docked, so I guess I can live
with it. And I do occasionally use them off of the dock using the
internal screen. So that all works, just don't raise the lid while the
external monitor is in use.
I have more of these same models, but they all have XP on them. And
raising or lower the lid, Windows XP doesn't care (I always have it set
to do nothing with the lid switch). If I want to switch to another
monitor, XP allows me to but I have to do it manually.
