yeah, we need to buy the external piece to cool off this laptop.
Kinda sad to hear about ur services, if I were u... I'll be shouting at that person who hand in the laptop.. haha!!!
We should get a good service anyway...
I've read thru your post about the heating up.
Well, actually, our model which is 5560 - 5563 have defect, in terms of the flow of the hot air.
To get rid this kind of problem, try to use cooling pad + heat extraction fan.
I recommend the "Magic" from Evercool. It's an extraction fan where it extract hot air from your laptop.
