I bought a laptop that came with a broken charger, I could easily test it myself as a friend also had an HP laptop with the same brick (this was before the days of USB C).
I tried to make a warranty claim and they wanted me to send the laptop too and wipe the HDD, the RMA process would take weeks on top of that.
I ended up buying a 3rd party charger, I’m sure their RMA process is overly long and convoluted to deter people from making warranty claims
