apxd1-dm wont power on

[biqut2]

I have two apxd1-dm motherboards I have purchased from  a retailer to use in a custom CNC setup. I chose this motherboard for it small size and price. I can't seem to get either of them to power on. I purchased a new 19v power supply, have it hooked up to a monitor via the vga port and it just never powers up. These came from a reputable retailer that I have done lots of business with in the past so I think it is highly unlikely that I have two DOA motherboards. Any ideas on what to check? I have 4 GB of ram in each mothorboard and two solid state hard drives.

Welcome to the HP Forums 🙂 
I would like to take a moment and thank you for using this forum, it is a great place to find answers. 
 
As I understand the motherboard you've purchased isn't powering on,

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details: 

Did you ensure power is being supplied to the parts?

here's what you need to know:

• Checking the power source
• Power supply fan is noisy or having interference
• Power supply light does not turn on or power supply fan does not spin
• Testing the power supply separately from the system
• Power supply light is on and flashes
• Ordering a replacement power supply

The power supply funcions just fine, I have verified voltage and current being upllied as well as tested with another computer. The problem is elsewhere.

Thank you for replying, 

I understand your concern and if you've confirmed that there is power being supplied to the motherboards and yet the issue persists,

This could be a hardware malfunction within the motherboards and hence, I have brought your issue to the attention of an appropriate team within HP.  

They will contact you shortly and likely request information from you in order to look up your case details or product serial number.  
Please look for a private message from an identified HP contact.  

Additionally, keep in mind not to publicly post personal information (such as serial numbers and case details).
