Connect tower to my desktop

[Brutus-02]

I need to know what cords go where on the back of my tower. I have 3 USB cords. A green round one is connected to 1 of them.

Hi @Brutus-02,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

I understand how confusing this can be; those ports can look very similar, especially when you’re setting things back up. I’ll help you get this sorted.
 

From what you’ve described:

• The green round connector is typically for a wired mouse (this is called a PS/2 port).
• The USB cords (flat rectangular connectors) can be used for devices like:
  • Keyboard
  • Mouse (if it’s USB instead of round)
  • Printer, webcam, or other accessories
     

Basic guidance:

• The green round port → Mouse
• A purple round port (if present) → Keyboard
• Any USB port → Keyboard, mouse, or other USB devices (they can usually go into any available USB slot)
   

To make sure we guide you correctly for your exact HP tower, could you please share a clear photo of the back of the tower?

Once we see the ports, we can:

• Identify each connection for you
• Tell you exactly where each cable should go
• Help avoid plugging anything into the wrong port

We’ll take it step by step with you once you share the image.

I hope this helps.

Take care and have an amazing day!
