HP Elitedesk 800 G3 DM Power Supply for 800 G4 DM?

[ncg]

Hello,

I have a HP elitedesk 800 G3 DM 35W with a 65W power brick. I recently got an elitedesk 800 G4 DM 65w and when I plugged it in, I got the 3 short 4 long beeps so seems like a power supply issue. Wondering if my 65w power brick that I got with the G3 can be used with the G4? I read something about a smart pin but really was not sure. 

I did try to search the forum but came up empty.

Hi:

The 65W power adapter only works for the models with the 35W processors.

You need the 90W or 150W power supply for the 800 G4 DM 65W processor model.

Thank you! It seemed a bit counter intuitive to me but I appreciate the quick response. I can’t seem to find the service manual specifically for the 800 G4 DM but wanted to clarify if this is the part number from the manual if you happen to have it?

You're very welcome.

Yes, that part number should work, but it is on back order...$91.13.

If you click on the part number, it will provide a list of models the power supply is good for.

It appears they are using the same power supply used in the G5 and G6's for the G4's.

If it were me, I would be buying a used but tested and working P/S on eBay be it the old or new part number.
