Unsupported Adapter installed

[KennyRH]

Hi, I bought a couple of 2nd Hand L2L47EA#ABU All in One PC 27" from an auction site, and also purchased an HP 130W PSU for them.

I also get the dreaded 3 long 4 short Beeps for 5 times, then get the error of Unsupported Adapter installed.

I can get the system to boot up by pressing ESC and F1 then F2 after the "Beeps" and everything works fine.

I've heard that the PSU needs to be a "special tipped one ?"

Is this true?

I took out the WiFi adapter and Hard Drive but it still did the same.

Another issue I have with the other computer, apart from the "Beeps" is that the UEFI ( or is it the NVME?) isn't recognised so I can't run the OS from it, anyone got any ideas?

I tried another SSD module in it, but still no response.

Would appreciate a solution.

Thanks

Kenny

Hi, Kenny:

Below is the link to the parts list for your PC.

HP PartSurfer

681058-002

Power Supply - EPS 2.0, 150W, 19.5V/89% eff

It doesn't seem that a 130W P/S furnishes enough power to the PC which is why you are getting that error.

I recommend you go on eBay search by the HP power supply part number and buy a used but tested and working genuine HP power adapter that references that part number.

681058-002 for sale | eBay

The parts list indicates the PC came with a 128 GB PCIe (NVMe) SSD.

757759-001

Solid State Drive - M.2, GNRC, 128GB, 2280SS, PCIE, EC0

So any M.2 NVMe SSD should work.

A SATA M.2 SSD will most likely not work.
