check the operation of the system and some options. This series of tests is

called the Power-On Self-Test, or POST. POST does the following operations.

• Checkssomebasicsystem-boardoperations

correct the cause of the ﬁrst error message, the other error messages

probably will not appear on the screen the next time you turn on the
