Temperature Concerns

The customer may perceive this system to run hotter than previous models. However, the normal operating temperature is well within national and international safety standards. Still, customers may be concerned about the heat generated by their machine. To prevent an unnecessary repair, you can compare a customer's computer to a running model, if available, at your repair site. For more information on temperature concerns and customer perception, refer to Knowledge Base article 30612 Apple...

System powered test using Caps Lock LED

There are situations when the system is giving indications that it is shut down (no sleep light, no hard drive access, screen is dark, no fan, and so on) however, the logic board may still be active.
