Maybe been a while since you had a new computer? Consumer laptops just do not support docking stations any more. HP has not had a clip-down powered docking station on the consumer lines in years. Here is the Service Manual:
External ports are identified on p. 7 and 8. The port you ask about may be the wired network RJ-45 port.
If you want expansion as with a docking station you will have to use a USB "port replicator". A true "docking station" powers the laptop and also has a switch to turn it on and off. You would not have those features but could add extra monitors, external keyboard and mouse, speakers, etc.
Thank you, no i have had to replace the laptops almost every year (unfortunately) since they seem to break down. My previous one was also an HP that had battery/power issues. Anyways, you're correct that I have not attempted to gain additional ports via a docking station (as i do with my work laptop, also an HP).
I will look at the pages you recommend. Thanks again.
