Laptops lifespan increase?

My lappy is lenovo g580 and specs are win7 ultimate, win8 pro, i5 3rd gen quad core 2.5 ghz,4gb ram,1gb nvidia gt610,500 gb hdd. I use my laptop basically for heavy games like splinter cell blacklist, assassins creed black flag, batman arkham origin, sleeping dogs, resident evil 6, any latest games. My laptop is 1.5 years old. I'm worry about laptop.so please how my lappy will last long and how to increase lifespan? I don't play games everyday and not use laptop everyday. I use to play games in summer and winter 8hrs daily.

If you use your battery for playing heavy games as this, the performance will be downgraded very badly… If it is heating up issue you talking about then just take a break between playing for hours… I too have a laptop of about the same configuration and i have been playing games for hours but on charging… To decrease the heating up of your lappy, remove the battery when on charging.
