Not sure there can be such a thing as different makers have different policies and recommendations, but more importantly, different technologies require different maintenance. For example, there are several different battery types used in notebooks. There could be Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH), or Lithium Ion (LiON), and even several types of fuel cell technologies are starting to emerge. They all require different maintenance.
So, I recommend you read your owner's manual. It will tell you how to properly maintain and use your notebook. If you don't have your manual, you should be able to download a copy from the maker's website.
That said, all electronics is adversely affected by excessive heat. So with any notebook, it is important to keep all the vents, fans, cavities, slots, bays, etc. free of heat trapping dust.
