Overheating was always a problem with the older, non-Centrino notebooks.

Now one of the ways that Centrino technology overcomes the heating problem is by creating more an improved airflow through the notebook, in addition to lowering the power requirements.

The older laptops usually have 2-4 air ducts or openings which may or may not have a fan. Sometimes, these may get slightly clogged by dust, or blocked by an external interferance. Against dust, which is the more obvious issue, a can of Spray Duster would easily reduce the problem. With some of the laptops, which may or may not have air ducts at the bottom, rather than at the back of the laptop. Some devices exist to blow air UNDER the notebook, which has a noticibly cooling effect. in any case, leaving a reasonable gap for air to flow, with or without an external fan, aids in cooling the notebook by creating a greater surface area for conduction to take place.
