HP Elitebook 840 G5 14-inch FHD (1920x1080) Business Laptop With Charger LOCKED

This is something that I picked up from a garage sale! I dont know much about it but its a pretty unique item! This laptop is locked to a company! I have the password to get in, however the administrator on the laptop is the company, and I’m not techy enough to figure out how to get past this! Only purchase if his works with you! Comes with charger
