The workstation turns off immediately after power is applied. I thought about connecting another power supply, but could not find the pinouts for the motherboard power port and CPU power for the Z440. Can you please tell me the port pinouts on the motherboard of these ports.
Thanks for manuals. I studied the manuals, was able to connect other power supplies to the motherboard, but it did not help. The situation is such that the motherboard, in principle, detects errors when not connecting the processor or RAM. But when the test bench is assembled, namely (motherboard + processor + RAM + processor cooler, video card, hdd with Windows), then when the power is turned on, the system starts up and after 5-7 seconds it is cut down, no red blinking or sound signals no, not even the loading screen has time to load. What could it be? Please help.
1. check the cpu/cooler, remove it and check for proper contact between the cpu and cooler by visually inspecting the thermal paste for proper spreading also confirm proper xeon cpu family the z440 only supports v3 or v4 cpu's
2. BUY THE CORRECT POWER SUPPLY, they are quite cheap i've seen many cases where the non HP supply was supposedly connected correctly and appon replacement/inspection it was found not to be so
