Macbook Pro / AIr – SMC Reset / PRAM Reset



Broadway Computers :
PRAM Reset :
Your Mac stores certain settings in a special memory area even if it is turned off. On Intel-based Macs, this is stored in memory known as NVRAM; on PowerPC-based Macs, this is stored in memory known as PRAM.

Information stored in NVRAM / PRAM includes:

Speaker volume
Screen resolution
Startup disk selection
Recent kernel panic information, if any
If you experience issues related to these functions, you may need to reset the NVRAM or PRAM. For example, if your Mac starts up from a startup disk other than the one you’ve specified in Startup Disk preferences, or if a “question mark” icon appears briefly when your Mac starts up, resetting NVRAM / PRAM may help.

System Management Controller (SMC) Reset:

It is possible that the SMC could encounter an issue that may cause unusual system behavior typically related to the symptoms described below. In some cases, resetting the SMC may be the only correct method to resolve the issue. However, an SMC reset should only be attempted after all other standard troubleshooting has been performed.
