Understanding POST

When you turn on your computer, a routine called POST (Power-On Self-Test) automatically runs to test the computer components. System logo appears on the screen during POST.

Screen messages are built into the computer to report both normal and abnormal system conditions. If an error message appears, take any action suggested in the message. If the message identifies the error condition but does not suggest any corrective action, write down the message and contact manufacturer or an authorised service center for assistance. (See ”Troubleshooting” on page 95.)
