POST
When you turn on the computer, it performs a series of tests to check the operation
of system components and some of the options that are installed in the computer.
This series of tests is called the power-on self-test or POST.
If POST finishes without detecting any problems, the first window of your
operating system or application program appears.
Notes:
1.
If you have a power-on password set, you must type the password and press
Enter, when prompted, before POST will continue.
2.
A single problem might cause several error messages. When this occurs, work
to correct the cause of the first error message. After you correct the cause of the
first error message, the other error messages usually will not occur the next
time you run the test.
POST beep code descriptions
The possible types of beep codes that your system might emit are:
Repeating long beeps
Indicates that a memory error has occurred. Ensure that all RIMMs are
correctly installed.
One long beep and two short beeps
Indicates that a video error has occurred and the BIOS cannot initialize the
video screen to display any additional information. Ensure that the video
adapter is correctly installed.
Small computer system interface messages (some models)
The following table lists actions to take if you receive any error message.
Note:
If your system does not have a hard disk drive, ignore any message that
indicates that the BIOS is not installed.
