How to turn off standby mode on IBM ThinkPak Lenovo

I want to connect the Lenovo IBM ThinkPad laptop to a bigger LCD monitor to work easier on the big screen but when I fold down the monitor of the laptop then the computer automatically go to standby mode.  Anyone knows how to turn off that standby mode so I can work on the bigger LCD monitor? My laptop has VGA connector only (3 rows of 5 pins) and run XP Pro.  thank you.
