I'm DooMguy and I'll be your tech support for this question
Generally when it comes to laptops, thinner and lighter is better. You really don't want some chunky old thing that overheats after 20 minutes of use. What you want is a cold, slim thing that's also quiet (you really don't want to hear the fan grinding)
It's worth paying attention to the RAM realistically you're going to need at least 4gb to be comfortable. The cpu. . . that's just a long story
As for the HDD, you'll want it to be at least 500gb
Also you'll want a decent keyboard (one which doesn't jam) because. . . well you know, you can't really replace it.
That's just a general overview really. . . but above all of that the true sign of quality is warranty, 2-3 years warranty and it should be good, very good.
Yeah. . . not sure if that was all that helpful, I ain't sure what you want it for. If you want me to write more about specs/hardware just say the word
