In that case I'd suggest getting a gaming laptop for gaming and a cheaper one for work. Any laptop powerful enough to run the most demanding games is going to consume a lot power, even when it's not running the games. There's just no way around it. I don't know what you do for a living, but I can't imagine there's anything you would be doing for work that would come close to exceeding what even a cheap piece of shit could handle. With the cheap work laptop you could focus on finding something with decent battery life since the other specs wouldn't be an issue.

Edit: I also wanted to add that gaming laptops are meant to be plugged in when running games. Trying to game on battery power will a) cause the battery to last than an hour on a full charge as opposed to the usual 3 or 4 and b) the game will run too slow to be playable as part of the computer's attempt to conserve power.
