HP EliteDesk 800 G5 mini
Microsoft Windows 10 (64-bit)

Hi,

 

since HP EliteDesk 800 G5 MINI has a very small form factor and powerful CPU it perfectly fits for a development of a mobile robot base.  Naturally autonomous robots do not provide AC power and using inverter is not an desired option because of high power conversion and space losses. The computer only boots when connected to genuine 150 W AC adapter, other vice won't boot and emits 3.4 beep error(power failure).

A suitable 150W DC/DC genuine adapter does not seem to exist or I'm not able to find one. Tried several no names with same voltage and current ratings with no luck.

What are our options?

you need a power supply that has a pwr sense circuit, the HP supply is using a "one wire" sense circuit

 

this is what tells the system which power supply is connected 18.5 v (65 or 90 watt)

 

rather than fight HP and make a custom adapter or buying a expensive retail supply look at the Pico-ITX motherboards and pwr supplies that run off 12v DC

This took me by surprise, because I used Dell's product with identical form factor without this restriction. I could understand if this was a laptop and optimal battery charging was required.

I'm aware of small ARM CPU computers and they are no match when high computing power needed.

And I already have the HP.
