HP 5000c-ct Manuale Utente

There are a number of POST tests that are performed after the
BEEP Code tests.  Failure of one or more of these tests will result in
a displayed failure code (i.e., 03044).  It is extremely important not to
interpret a failure code immediately as a hardware failure until:

all accessories are removed, including memory cards external
floppy, port expander, modems, PCMCIA cards, LAN cards, printers,
VGA-out cables, external pointing devices, clean AC power is
provided (no "chained" battery chargers or auto adapters), and press
reset.

If the unit still fails to boot, it requires service.

NOTE:  make sure the display is adjusted to be visible.
