@rahulsantra,
Welcome to the HP Support Community!
I reviewed your post and I understand that you want to know whether you can add one more CPU on the computer.
Don’t worry, I assure you I will try my best to get this sorted.
I would like to inform you that there is no option to add one more CPU on the All in one computer.
I hope that answers your question and you have a great day!
If you wish to show appreciation for my efforts, mark my post as Accept as Solution. Your feedback counts!
Cheers!
