I want to buy a new Laptop. I currently have Dell Vostro 1400, but an IC in its charging port is damaged (cannot be repaired) so I have to use a UPS with my laptop (cannot run without AC supply).

I will use my laptop typically for watching anime and downloading. But I also need it to be powerful enough to run simulations in MATLAB (since I am an electrical engineering student).

Also I want it to be reliable.

So can any one suggest which brand i should buy (will be bought in Saudi Arabia) and which CPU should i use?
