Resetting PRAM

PRAM (pronounced P-RAM) is a battery-powered portion of your computer's memory where default settings for basic functions (including video display and what's connected to certain types of ports) and some system preferences (including the startup disk) are stored. If, on starting your computer, the picture doesn't display properly or other basic functions (such as the time) don't reflect the preferences you've set, you may need to reset the PRAM.

If you frequently have to reset your PRAM or your clock resets itself each time you shut down, it may be time to replace your computer's internal battery.
