<hardware> (POST) A sequence of diagnostic tests that are run automatically by a device when the power is turned on. In a href="module.php?name=Lexikon&file=search&eid=1&query=personal computer">personal computer a typical POST sequence does the following: - checks that the href="module.php?name=Lexikon&file=search&eid=1&query=system board">system board is working - checks that the href="module.php?name=Lexikon&file=search&eid=1&query=memory">memory is working - compares the current system configuration with that recorded by the PC' s configuration program to see if anything has been added or removed or broken - starts the video operation - checks that the href="module.php?name=Lexikon&file=search&eid=1&query=diskette">diskette drive, href="module.php?name=Lexikon&file=search&eid=1&query=hard disk drive">hard disk drive, href="module.php?name=Lexikon&file=search&eid=1&query=CD-ROM">CD-ROM drive, and any other drives that may be installed are working. When POST is finished, typically it will href="module.php?name=Lexikon&file=search&eid=1&query=beep">beep, and then let your href="module.php?name=Lexikon&file=search&eid=1&query=operating system">operating system start to href="module.php?name=Lexikon&file=search&eid=1&query=boot">boot. If POST finds an error, it may beep more than once (or possibly not at all if it is your PC speaker that is broken) and display a POST error message. These messages are often nothing more than a single ominous number. Some common numbers and their meanings are: 161 Dead battery (get a new battery for the system board) 162 Configuration changed (you added some memory or a new card to the PC) 301 Keyboard error (take the book off the corner of the keyboard) Because a successful POST indicates that the system is restored to known state, turning the power off and on is a standard way to reset a system whose software has href="module.php?name=Lexikon&file=search&eid=1&query=hung">hung.
