What happens to my laptop if a friend made a purchase on my laptop and then does a charge back with his bank, or uses a stolen card and the owner does a charge back?

Context:

A lent my laptop to my friend to make a purchase he used his own credit card, and is joking about making a charge back as it was done on my computer and can not be chased back to him. What will happen to my computer data wise if he does do a charge back and wins the case. Does my laptop get black listed or the hardware details is saved somewhere.

This makes me wonder as well is it the same if they were to use a stolen credit/debit card?
