No-beep symptoms
Important:
Type 2271/6840/6841 computers default to come up quiet (no beep and no memory count
and checkpoint code display) when no errors are detected by POST.
To enable beep and memory count and checkpoint code display when a successful POST
occurs, do the following:
1. Select Start Options in the Configuration/Setup Utility program (see “Setup Utility
program” on page 8).
2. Set Power-On Self-Test to Enhanced.

POST error codes
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,orPOST. POST does the following operations.
v Checks some basic system-board operations
v Checks the memory operation
v Starts the video operation
v Verifies that the diskette drive is working
v 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 the operating system or application program appears.
Note:
Type 2271/6840/6841 computers default to come up quiet (no beep and no memory count
and checkpoint code display) when no errors are detected by POST.
To enable beep and memory count and checkpoint code display when a successful POST
occurs, do the following:
1. Select Start Options in the Configuration/Setup Utility program (see “Setup Utility
2. Set Power-On Self-Test to Enhanced.
program” on page 8).
If the POST detects a problem, an error message appears on the 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.
In the following index, X can represent any number.
