Windows keeps defaulting to dual video output!?

[aceo07]

Every time I close my Thinkpad x40 lid, while it's on, it will default to using dual video output when I open it back up. Is there a way to stop this behavior?

^bump. Can I get this moved to Windows forum? I don't seem to be getting much response here.

I don't know much about the X series, but have your looked at the BIOS settings to see if there's an option to control this behavior?

In the BIOS, it's set to use only LCD on startup. That's the only option that seems related to video output.

After I close my screen and reopen it, the OSD will tell me I have both video outputs active.

This is a problem since dual video output will drain 0.5watts more than single video output. I can stay under 9watts using wireless, medium brightness and web browsing if it's just single video output.

I have run into the same problem with my X21. Even worse, if I extend the external monitor, my X21 (1024x768) cannot do higher than 800x600. These are not acceptable, so I dropped the idea to use an external monitor.

I love X2* very much - they run so darn cold and quiet! However, the aged BIOS really has these and other issues with XP. For example: it never turns off the monitor after 15 min idle (actually it does but then turns it on shortly for no reason) or go into sleep mode; it crashes into blue dead screen sometime right after wake up or a network failure (WiFi PC card or built-in Eithernet); the mouse and some keys do not work sometime after wake up. Such unpredictable crash is unacceptable for business, so I no longer use my X2* as my primary computer but for entertainment only. Sigh.

Now waiting for the Fujitsu U820 to come to U.S., then it will be my primary and only computer for years to come.
