Dell Latitude Laptops are quite good. I never have problem

Even I abuse quite bit for my company laptop. It still works fine.

Few times, My laptop was on when it's packed in my backpacks. When I realized, the system became very hot, everything still wroks fine.

The problem cause the laptop powered on in the bag because the sleep mode somehow got waked up due to the movement of my bag(I am not sure if this is normal).
