You cannot -- you need the registered owner's information (name/email/phone number) at least.   
Hello colleagues, I bought a laptop not long ago to a person, the computer looked in good condition and after a while of use it turns out that I keep it had password in the bios I forgot the bios password, then I do not have how to contact the person who sold it to me I did not know him I do not have his contact I do not know where he lives, try with Dell technical support and fill out a form for them to help me I fill it out I wait 20 days the computer appears on my device. When I go back and contact tech support they tell me ok we will help you they send me a code that did not work and tell me I have to call tech support where I live to help me, I call and the first thing they tell me they can not help me without the invoice of the computer and I tell them for something fill out a form and wait 20 days they tell me no without invoicing they can not help me they give me an address of a technician that I do not know if it is certified by Dell the same. Do you think it is possible to get the invoice without being the buyer of the computer but the current owner. Regards JenselPC.
Is it possible to recover the purchase invoice of a computer if you bought it 
second-hand?
