Lenovo 8098 manual Post error codes

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-OnSelf-Test, or POST. POST does the following operations.

vChecks some basic system-board operations

vChecks the memory operation

vStarts the video operation

vVerifies that the diskette drive is working

vVerifies 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.

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.
