I work in a company selling used computer equipment. I just made good deal from big supplier with notebooks dell. I have an invoice for all notebooks. All DELL notebooks have password on the bios. The model is DELL E6410 and I have more than 50 pcs. They are out of warranty. I contacted dell in my country but they did not help me. I hope that i will find understanding here and someone will help me as so many notebooks with password is too big problem for me. Please help me.
Wherever they were purchased, if the seller cannot transfer the ownership to you or remove the password, you will be purchasing a new mainboard for each system that's locked with an unknown password.
I have a Dell laptop from one day to the next it appeared with a problem, without having exchanged any parts.
As soon as it is turned on it prompts for password and displays Service TAG B6NV9X1 and does not continue.
If you're 100% certain you did not set a password, and no one else did -- i.e., no one else had access to the system, it's a mainboard failure -- replace the system board.
You might try resetting the BIOS to original factory state to clear the BIOS password. Following is a link to the Dell KB article describing the process. Click on the notebook tab for the proper instructions.
