How do you enable Clamshell mode?

connect the keyboard, monitor and mouse. After connecting these devices, put the computer to sleep. Close the lid. Click the mouse or click a key and the computer will spring to life.

 

Attach an external mouse and keyboard to your PB. Close your PB (put it to sleep). Wake it up by touchng mouse or keyboard (you need to adjust Systm Preferences so that Mouse/Keyboard can wake up the machine). Afer that, you can keep the lid shut or you can open it (your PB's screen is off). If you download the update and need the re-boot, you can just let PB restart and it will start in the clam shell mode.

 

It's amazing Microsoft hasnt figured out how to do this yet.

 

so you can do "clamshell" with a Bluetooth mouse and keyboard? that's cool, i thought you could only do it with USB.

 

That's because it's more of a hardware thing than a software thing. MS doesn't make laptops. My mom's IBM laptop from work (pentium II 266MHz) allows you to close the lid and use it with an external monitor, keyboard, and mouse.
