Help me choose the best student laptop from this list

Hello, I really need your help choosing the best laptop for the university as an Electrical engineer - so I guess I won't need so much of a graphic power, but rather a good battery life/performance ratio.
This is the list: (scroll down in each page to view full specifications - it's the website of the store I'm buying from)

I truly need your help because I've never had a laptop and I don't know which is the most reliable, and has the best screen,battery life, performance, service etc.
*I've also chosen the i5 and not i3 or i7 because I thought it would be the best for a student on this budget (not too expensive, not too slow)
Thank you

Update : I bought the Lenovo IdeaPad G510 with Intel Core i5 4210m, and the AMD R7 m230 2GB GPU.
This is a nice laptop, however, I am not too happy with it as a student.
Next time I purchase a laptop I'll have more experience, so I'll probably know what to choose myself, and I will try to explain:

This laptop is quite heavy and thick! for a student I'd recommend a thinner and less heavy device, even if the battery life is shorter (I'm not sure the different is going to be too big, and I'm sure you can find power outlets before the battery runs out in a university)

Next time, I will surely choose a Full HD screen, I really don't like the quality of this monitor, it hurts my eyes.

I'm not sure I really need the Graphics card as a student, and besides, so far this laptop is only using the Intel HD Graphics (it is automatically switchable, and for the apps I use it just won't switch to the AMD, so render that useless)

I should've bought something perhaps more expensive, but with a Full-HD screen, less weight, and not even care if it has a graphics card or not (the intel is definitely enough for a regular student)
