HP ProDesk 490 G2 User Manual

Activity Beeps Possible cause Recommended action
until failure occurs. Replace the device that is
causing the failure. Continue adding devices
one at a time to ensure all devices are
functioning properly.
3. Replace the power supply.
4. Replace the system board.
Red Power LED flashes five
times, once every second,
followed by a two second pause.
Beeps stop after fifth iteration
but LEDs continue until problem
is solved.
5 Pre-video memory error.
CAUTION: To avoid damage to the DIMMs or the
system board, you must unplug the computer power
cord before attempting to reseat, install, or remove
a DIMM module.
1. Reseat DIMMs.
2. Replace DIMMs one at a time to isolate the
faulty module.
3. Replace third-party memory with HP memory.
4. Replace the system board.
Red Power LED flashes six times,
once every second, followed by
a two second pause. Beeps stop
after fifth iteration but LEDs
continue until problem is solved.
6 Pre-video graphics error. For systems with a graphics card:
1. Reseat the graphics card.
2. Replace the graphics card.
3. Replace the system board.
For systems with integrated graphics, replace the
system board.
Red Power LED flashes seven
times, once every second,
followed by a two second pause.
Beeps stop after fifth iteration
but LEDs continue until problem
is solved.
7 System board failure (ROM
detected failure prior to
video).
Replace the system board.
Red Power LED flashes eight
times, once every second,
followed by a two second pause.
Beeps stop after fifth iteration
but LEDs continue until problem
is solved.
8 Invalid ROM based on bad
checksum.
1. Reflash the system ROM with the latest BIOS
image.
2. Replace the system board.
Red Power LED flashes nine
times, once every second,
followed by a two second pause.
Beeps stop after fifth iteration
but LEDs continue until problem
is solved.
9 System powers on but is
unable to boot.
1. Check that the voltage selector, located on the
rear of the power supply (some models), is set
to the appropriate voltage. Proper voltage
setting depends on your region.
2. Unplug the AC power cord from the computer,
wait 30 seconds, then plug the power cord
back in to the computer.
3. Replace the system board.
4. Replace the processor.
Red Power LED flashes ten
times, once every second,
followed by a two second pause.
Beeps stop after fifth iteration
but LEDs continue until problem
is solved.
10 Bad option card. 1. Check each option card by removing the card
(one at a time if multiple cards), then power on
the system to see if fault goes away.
2. Once a bad card is identified, remove and
replace the bad option card.
