The Power-On Self Text (POST) is a series of diagnostic tests that runs automatically when the

Audible and visual messages occur before the operating system starts if the POST encounters a
problem. POST checks the following items to ensure that the workstation system is functioning properly:
●
Keyboard
●
DIMMs
●
Diskette drives
●
All mass storage devices
● CPUs
●
Controllers
●
Fans
●
Temperature sensors
●
Cables (front/rear panels, audio, and USB ports)
The table shown next describes the POST error messages.

Recommended action
Verify the correct ROM:
1. Flash the ROM, if needed.
2. If an expansion card was recently added, remove
it to find out if the problem remains.
3. Clear CMOS. If the message disappears, there
might be a problem with the expansion card
4. Replace the system board.
1. Clear the CMOS.
2. Remove the expansion boards.
3. Replace the system board.
Run the Computer Setup (F10) Utility to disable
unneeded option ROMs, and to enable ACP0/USB
Buffers at Top of Memory.
1. Set the date and time from the Control Panel or in
the Computer Setup (F10) Utility (depending on
the operating system).
2. If the problem persists, replace the RTC battery.
