Power-On Self-Test (Post) - Compaq Armada E700 Series Maintenance And Service Manual

2.2 Power-On Self-Test (POST)

The Power-On Self-Test (POST) is a series of tests that run every time the computer is
turned on. POST verifies that the system is configured and functioning properly.
To run POST, complete the following steps:
1. Complete the preliminary steps (Section 2.1).
2. Turn on the computer.
If POST does not detect any errors, the computer beeps once or twice to indicate that
POST has run successfully. The computer boots from the hard drive or from a bootable
diskette if one is installed in the diskette drive.
