8355 N/B MAINTENANCE 7. Maintenance Diagnostics 7.1 Introduction Each time the computer is turned on, the system bios runs a series of internal checks on the hardware. This poweron self test (post) allows the computer to detect problems as early as the power-on stage. Error messages of post can alert you to the problems of your computer. If an error is detected during these tests, you will see an error message displayed on the screen.
