Because availability is so important to students and teachers, Toshiba's notebooks and Tablet PCs have reliability built in. We've taken an engineering approach to this, selecting a solution because it is the best, not necessarily the cheapest.
For example, heat is one of the leading causes of component failure in notebooks, so we map heat flow in detail. This enables us to identify any hot spots created by heat generating components like the CPU. Then we redesign the component arrangement or change the way air flows within the system to prevent heat build up and reduce the risk of a problem.
Our Portégé and Tecra ranges are also a graduate of our Highly Accelerated Lifetime Testing process - a torture test that cycles notebooks through extremes of heat and cold to simulate several lifetime's use. This helps us identify potential design problems so we can fix them before we go into production.
