The main draw backs in HP ProBook 440G2 are
1)the processor is very slow.
2)display brightness is very low.
3)so much amount of heat is coming while operating.
4)drivers update is also very slow.
5)volume is very low.
6)performance is poor then compared to other laptops.
7)wire less connectivity is also poor.
8)key pad is not that much smooth.
9)connection between display and key board bad.
so I did not prefer to buy this laptop.
