PC Server 310 - POST Beep Codes
Applicable to: World-Wide
POST Beep Codes
The Power On Self-Test generates a beeping sound to indicate successful completion of POST or to indicate that the tests detect an error.
One beep and the appearance of text on the display indicates successful completion of the POST. More than one beep indicates that the POST detects an error.
Power-on Password
To service Type 8639 computers with an active and unknown power-on password, power-off the computer and do the following:
Note
This procedure will not remove the Administrator Password.
1. Unplug the power cord and remove the top cover.
2. Refer to 'System Board— on page 28 for the jumper location.
3. Move the password jumper to connect the center pin and the pin on the opposite end of the connector.
4. Power-on the computer. The system senses the change in the position and erases the password. - It is not necessary to move the jumper back to the previous position.
5. Remind the user to enter a new password when service is complete.
Power-On Self-Test (POST)
Each time you power-on the system, it performs a series of tests that 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:
- Checks some basic system-board operations
- Checks the memory operation
- Starts the video operation
- Verifies that the diskette drive is working
- Verifies that the hard disk drive is working
If the POST finishes without detecting any problems, a single beep sounds and the first screen of your operating system or application program appears.
If the POST detects a problem, an error message appears on your screen. A single problem can cause several error messages to appear. When you 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 system.
