HP Workstation xw4100 - POST and Error Messages

Power-on self-test

POST is a series of diagnostic tests that runs automatically when the system is turned on. An audible and/or visual message occurs if the POST encounters a problem. POST checks the following items to ensure that the workstation system is functioning properly:

  • Keyboard
  • Memory modules
  • Floppy drives
  • All IDE and SCSI mass storage devices
  • Processors
  • Controllers
NOTE: If the Power-On Password is set, a key icon appears on the screen while POST is running. You will need to enter the password before continuing.
