Here you go guys, not my proggy so thanks to original developer. This little thing is hard to come by. This will unlock your Dell computer whether it is BIOS or HDD master password. You need to enter the full Asset number including the "-" for the BIOS and the first ** for the HDD password. Even works with the dreaded 595B models. Enjoy!!

There is no need to post multiple requests for unlock codes. If a code can be generated someone will hopefully get back to you. Please be patient; duplicate posts will now be deleted without notice. EDIT----- I've changed the link to this to bit.ly....this is so i can keep track of usage due to my dropbox account being hammered. A quick search on the internet reveals loads of forums with this link lol. EDIT 5: The information provided on DW is supplied "as is", free of charge and without warranty or liability. In line with our "no traders" rule; any member found to be charging for unlock passwords will be banned.
