What is the POST (power-on self test), and what can be done to troubleshoot this process?

What will be an ideal response?


The POST is a series of tests performed by the startup UEFI/BIOS when you first turn on a computer. These tests determine if startup UEFI/BIOS can communicate correctly with essential hardware components required for a successful boot. If you have a problem that prevents the computer from booting that you suspect is related to hardware, you can install a POST card in an expansion slot on the motherboard. For laptops, some cards install in a USB port. Then attempt to boot. The card monitors the boot process and reports errors, usually as coded numbers on a small LED panel on the card. You then look up the number online or in the documentation that accompanies the card to get more information about the error and its source.
