Resetting SMC and NVRAM

I have covered resetting your SMC (System Management Controller) and NVRAM (Nonvolatile Random Access Memory) from time to time, but this article covers situations in which you need to perform these two troubleshooting steps. It is the most thorough look at SMC, and NVRAM reset I have ever seen. Give it a read and if you have any of the symptoms listed, by all means use one of these procedures. Be sure to scroll to the bottom of the article and go to the second and third pages.
