- thermal design has long been a weak point
-
Even Apple's laptops have suffered from poor heat extraction. What is needed in part is a better case and airflow design, similar to that used by Lenovo. With the Lenovo laptops the fan pulls air in from the side and it exists out the top so the flow is much less likely to be restricted when the user sets the laptop on their lap.
The other requirement is intelligent power consumption with the CPU only using as much power as needed for the tasks at hand. This is also a concern with dedicated video cards being added primarily for gamers but also potentially adding a lot of heat inside the case.
The mechanical engineer doing the case design is going to usually be the low man on the totem pole with the EE guys and gals in the driver's seat on product design and execution. Product design is treated as a linear process and this takes a lot of options off the table at the onset. Using a metal shell to fix a heat problem at the tail end of the process is bad engineering and the result of bad product design and ineffective product management. What is different about Apple is that Job's will not settle for what passes as design and engineering at other companies. - Posted by: stenman@...
