Laptop for a university college student

Hello.

I'm going to attend a university college this coming fall and that means that I need to get myself a new laptop. I was hoping that you guys here would have a couple of suggestions for me. The requirements I have for this laptop is that it needs to run all of the programs from microsoft office at a good rate. I don't care that much about games as I have a gaming stationary that I will also bring along to keep in my room.

Back during higher secondary school I had a Dell Vostro 3300 for 4 years with an intel celeron inside core, something I'd rather avoid this way around since the laptop started to freeze and such during my last year. I think that an I3 or I5 is more than enough in this case. RAM wise I think that 4gb should be enough, though 8gb RAM is no problem either. I would like to avoid an HDD if possible and get either an SSD or hybrid SSHD. (Though I could also just upgrade it at a later date with an SSD drive) I would also prefere that it has a quiet fan and a large battery. Size wise I think a 13.3 or a 14 inch is probably for the best. I don't really mind if it is an ultrabook or not though, since the Vostro 3300 was quiet bulky, so I am used to a somewhat thick laptop.

I have also been looking at some laptops myself so I was curious if anybody here have any experience with any of them, these are:

Lenovo Thinkpad L450
Lenovo Thinkpad L440
Asus ZenBook UX305 (128 GB SSD one)
HP Pavilion 13-b080

I would appreciate any help, as there are quiet a lot of laptops to pick from.
