Question

What causes the ‘55’ error code and no display on first power of the DIVAR IP all-in-one 7000 gen 4 (DIP74xx)?

Answer

Note that BIOS POST Code ‘55’ indicates that the memory is not installed or not detected.

Since this occurs on the first power on, the most likely cause is that the memory modules were moved during transportation.

To resolve the issue:

• Open the top cover

• Reseat all memory modules

• Power on the unit again and check if the if the issue is resolved
