Laptop guidance needed for Comp Science Student.

[Ranchboy]

I'll be using the laptop for coding and application development.
Most important qualities needed:

1. Solid Build.
2. Good Display.
3. Good Battery life.
4. I rarely game, so gpu doesn't matter.
5. Budget 700$

I'll be putting a 512gig SSD and ubuntu into the laptop once I get it so storage doesn't matter either. Warranty doesn't matter either as I repair laptops as part time.
Any suggestions are welcome. Also should I consider refurbished ones?

Warranty doesn't matter? Well the biggest cost in fixing laptop is parts not labor. Why don't you just buy a Ubuntu laptop from Dell?
