Desktop shuts down when moved

[Arnold14]

I've had my HP z620 workstation for a few weeks now and have recently noticed that it shuts down and/or restarts when it is moved/tilted while running. I have already checked the power supply and both motherboards for visible shorts, and the power supply light is green. Is there anything else I can do to fix this?

Thanks!

Can you please include more details regarding your workstation configuration, i.e. single or dual CPU, graphics cards and any additional PCI cards, RAM type and amount, SSD/HDD's, etc. The more information supplied, the easier it is to try and resolve the problem. However, this does sound like something is not fully seated on the motherboard.

I would start by removing all PCI cards, RAM modules and drives. If you have access to alcohol wipes (used to clean glasses) then I would gently clean the gold plated edge connectors on the PCI cards and RAM modules. Re-install the minimum hardware to boot the system, i.e. 1 CPU, 1 RAM module, the OS drive and a graphics card and see if the problem still exists? If everything seems okay, then proceed to re-install any remaining hardware and re-test at each stage.

Thanks for the help, turns out the front panel connector had shorted and the power button connector was bridged if the machine was moved, therefore turning it off.
