I've been running my Macbook Pro on clam shell mode for a while now, as I primarily keep my laptop on my desk using a wireless keyboard and mouse with it. I like to use a bigger screen when at my desk as I'm usually doing music or photo editing.
This has lead me to nothing but problems with the power source of my laptop. Since you have to supply power constantly while running clam shell mode, it tends to shorten the life of the battery. I've already replaced two batteries within a year, and the laptop is no more than 2 years old. Luckily my Apple Care warranty covered it, others may not be as lucky.
Now recently, my charger stopped working. I took it in to get replaced, and they gave me a brand new one. Brought it home, had it plugged in over night, and the next morning it stopped working as well. However it works on other Mac's I've plugged it into. I don't know if it's my laptop or what, but ever since I've been using clam shell mode, I've experienced nothing but problems. I'm posting this just to give fair warning to anyone else who may want to use it or experiment with it. Maybe I'm a little behind on the curve and this is old news, but oh well. Just thought I'd share my problem for others to know.
