I suppose you tell them it's been damaged and you want a new one.

HP offer ARs (Advanced Replacements), whereby they ship a replacement unit and upon receipt, they expect you to send the defective one within 15 days.

Failure to do so, may result In your account being debited for the cost of the Item. Do take this under advisement with your SE.

Thank you, any more tips to how to pull this off?

As you've stated, tell them that you've disposed of It, namely for health & safety purposes.

Alternatively, use a drop address/house.
