u/Aspiring_Reject

I got gifted this Dell precision M4600 back in high school. I used it for about four years and then when I moved it just got put in the box. Well now five years later I find it and found out it still turns on! Only problem is I forgot the password. Is there anyway to factory reset it without putting in the password? I also don’t have the Reset disk, but I’m willing to buy one off of eBay or something if it’s cheap and that’s the only option.
