External display draining my MBP's battery

[Smarterchild]

Hey, i have a mbp with a 19' HP display hooked up to it right now. I believe it runs off the main computers power(wasnt aware when i was switching outwith my old HP tower) but its running through my MBP's battery life about 10% every 5-10mins. Is that good or bad? And if its good for my battery and mbp in the long run to leave the charger constantly on it to supply my display.

Well your display cannot be possibly draining your battery the way you put it, your display should have its own direct power supply. No displays run off via anything, its all directly powered. anyways you are using battery because of the graphics card usage, prob needs to run more when on ext display mode. There is nothing wrong with having your mac continually plugged in as long as you drain and charge it every week or month etc, look up articles/posts on how to manage/condition the battery.
