I wanna buy a laptop

I'm a grad student at a civil engineering department. I really wanna buy a laptop. As a civil engineering student, I will be dealing with softwares like AutoCad, SAP2000, Etabs, Matlab, Ansys, … Etc. So guys please I need your help, what do you recommend? Lenovo? HP? Toshiba? Dell?
Also, if there's any discounted deals for students, I will appreciate letting me know.

Lenovo ThinkPad. Nothing else. You will not regret it in the least, I assure you.

Hi so you pays your money and you take a chance it really is that simple. The best one would be an apple. However money is the usual reason why they chose to buy lesser machines.

My Civil Engineering classmate only used AutoCAD, Solidworks, and Matlab while in school. He had them and Windows installed on his Macbook Pro. Apple offers student discounts around every July-August time frame. You just need to give Apple your school email address for the discount. I got my Macbook that way. It came $100 off with a free printer/scanner/copy machine and a free iPod mini at the time. I used it in engineering mainly for Microsoft Word, Excel, and Powerpoint. It turns out in engineering, you don't need to spend thousands of dollars buying AutoCAD, Solidworks, Matlab, and other programs because the school has them already installed in their free computer labs. Also, you only use these software's for 1 class, 1 semester (~10 weeks), maybe once per week. It is not worth buying those software's or buying a laptop that can use those software's.

Even when you graduate and get a job, those software's should be installed on your work laptop, which you are allowed to take home. Why spend thousands of dollars on these programs when they are already available to you for free?

Anyways, any laptop is fine for engineering as long as it has 4GB ram and a processor that is NOT an Atom processor (found in netbooks and very small laptops)
