How to dell latitude d620 bios password reset free

use a password reset disk if you have one.
can't help you with any kind of bypassing password protection. there is no way to verify you as the legitimate owner.

Toms hardware does not allow discussions about bypassing passwords or security. Please read the forum rules. password are there for a reason, especially a bios password, we have no way to know it's your laptop, and it's extremely strange to forget a password you use every day.

You will have to contact Dell and provide PROOF of ownership.
