Bigger powerbricks with splitters perhaps?

High wattage 19.5V 7.4mm are usually harder to find. Most common are 65W chargers.

HP uses two different voltages for the 7.4mm black tipped chargers: 19V and 19.5V. Not sure if both will work with the latest gen mini PCs but 19V chargers will work for these. I’ve had a hard time looking for 120W 19.5W chargers that 705 G1 minis used that I had to resorted to using 19V ones.

Their laptops use the smaller 4.5mm blue tipped chargers. Makes sense since these laptops are too thin.

I have the same question. We are about to sunset about 20 of these at work. I could take them but would have no clue what to do with them. I have zero interest in learning Kubernetes as the network I sysadmin for is so dirt simple as far as servers go. VMWare cluster maybe? Proxmox cluster?

Look for a Lenovo M720Q, M920Q, or M330. All of them not only do VT-D and IOMMU but even have a real PCIe x8 slot. I picked up an M720Q for $220 CDN off FB Marketplace and it’s my Proxmox server running pfSense, Window Server 2016, Turnkey-NAS (using an 8TB and a 16TB USB 3.2 Gen 2 10Gbps external hard drives), Pi-Hole, and a battery backup monitor LXC.

I have 32GB RAM in it, but even though the docs say that’s the maximum I’ve been told by several people that you can actually put two 32GB modules in them for a total of 64GB. When the M720Q was released 16GB was the biggest RAM module you could get.

No cluster yet, but someday…

A lot of these devices are above 12v so with that said yes it can be done but it would require a special power supply that puts out enough watts and enough volts at whatever the voltage is cut the power ends leaving the ferrite on make sure you keep center Pin Positive or Negative whatever they are or meter to find positive and negative before you fully cut them off the bricks and viola a power supply. I’m guessing a lab power supply would likely come close to what you need its adjustable in voltage and amperage.

I’m currently in the stages of taking the other route I want multiple cores and virtual machines = less electricity. Looking at getting cloudmin running only 75 big ones a year less than I would spend on having another rig up a whole year. IDK just seems like it’d be the way to roll if you ask me beef up one server run KVM and viola done deal. Everything managed from any TV in any room of the house with a video network and a switch 4k management of multiple servers with a single server sipping electricity. The savings in electric will pay for the expense over time. So no point in cheaping out here. Bit of a curve at the moment but I’ll get there.

Perhaps, i tried reading up about it, looks like HP will not just accept 19V and needs some sort of verification of the power supply’s capabilities. It will just run in “Low power mode” if only 19V is supplied and no data signal

is there not just a simple jumper header for clearing cmos?

That actually sounds like a fun challenge! Good luck to you!

Honestly I have no clue why you’d need a cluster at home either. But I guess it’s fun to tinker? A raspberry pi cluster would be cheaper though and have the same result.
