Laptop purchase for disabled

[Sunnydee]

I'm currently working for a 15 year old with A typical Autism and ADD and he asked me to look over a computer he can use for a year or 2.

His budget isnt that big sadly but had my eyes on 3 different laptops and wonder if someone could give feedback on which one would handle browsing, flash games to help him out and some minor games (heartstone, sims and such)

3 currently ive spotted is

Compaq 15-s000so

Toshiba Satellite C50-B 14M

Lenovo IdeaPad G50-30

Edit:also able to get my hands on a Sony Vaio SVF1521E6EW which is 3 months old and roughly half price of storebought.

Im absolute horrible when it comes to laptops so here i am asking u guys, whatcha reccon?
