Laptops always break after 4/5 years, from experience. In compagnies , they're changed every 5 years, and that's how i had a few short-term contract since a few years.
An that's the reason why i'll quit laptop for my next computer and return to a desktop PC. Less expensive over the long-term, more on the short-term because you have to buy a screen, a PC case, the CPU/GPU/RAM/MB and so on.
