I ask for help.
There is a system unit "HP ProDesk 600 G1 Small Form Factor".
The system unit configuration has changed:
CPU - Celeron g1640
RAM - 2Gb Samsung.
There is a problem when supplying power to the PSU, while the battle is heard the BIOS signal (two long beeps).
Without a CPU (or 4p power supply of a CPU), the number of beeps is more than 3-4.
I tried with other RAM slots - anyway, 2 beeps.
The battery shows exactly 3 volts. I can’t answer for the processor.
1) Could the g1840 CPU be not compatible with a 600 G1 motherboard? (I read on the net that there are HP computers that can only work with ATI Radeon 7000 series).
2) Please give a link to a list of compatible processors.
3) Where can I connect a POST card (there is a PSI x1 and a LPC port of 2 pcs.)
4) Is it possible to update BIOS without booting? Will this help?

Below is the link to the quickspecs for that model series.
I do not see the G1840 listed as a supported processor...1820 and 1830 only.
Below is the link to the service manual which has the beep code translation...chapter 9 starting on page 194.

Thank you for your informative answer. Judging by the documentation, I have a problem with determining the connection of the cooling system for the CPU. However, replacing the fan with 4 and 3 pin ones did not solve the problem. With any fan in the CPU fan 2 sound signals.
Is the CPU or motherboard to blame?
After applying voltage, 12 volts rise for 1 second on the CPU fan connector

After CPU installation: Pentium G 3250, which is missing from the list. The system unit turned on without any problems.
