As the title suggests i bought a second hand laptop from some guy on facebook market place. The problem i cant login to it and it seems to have been an old company laptop. It has a user thingy.

My thing is i cant find the dude anymore cause he deleted his account and we met at a neutral location so idk where he lives. So what can i do know, i still want to use the laptop but i cant login to factory reset.

Basically im just asking uf anyone has any software or tips that can help me factory reset this crap laptop.

Its a Fujitsu lifebook A series seriel number A555

Please and thank you 😓
