My Macbook pro In clamshell mode
After i got my macbook pro, my almost new LG LCD monitor was gathering dust, what a waste i thought, i imagined that mac os x will look great in the 19" monitor and frankly speaking surfing the web on a laptop is not very nice on the eyes.
I went down to parkway parade and went to the apple store at best denki and bought the mini display to dvi wire for $44 bucks, came back home connected the the wire to my LG monitor and bingo I have dual screen now
But i wanted only one screen that is my mac screen to close, so i got in touch with mac support and they send me the instructions to me via my email, I followed the instructions and voila, just closing my laptop lid and pressing my mouse activated the LG monitor as my default screen, but the macbook has to be connected to the main power, it won't work if you just use the battery power.
I had an external usb mouse and was considering if i should buy and external keyboard and lo and behold what a surprise i got when i open my laptop lid and found my keyboard illuminated but the laptop screen remained off, just what i needed, now there was no need to get an additional keyboard.
Now i have the best of both worlds :)
