Hi m_helal,
For security measures and to best serve our customers, we can help with password information to the rightful owner. We would need to verify that you are the legitimate owner of the Laptop. For this we need the System Service Tag and First and Last Name on the Account (i.e., the Registered Owner’s first and last name). Providing this information in the open forum is violation of Dell Website Terms of Use and the Dell Privacy Policy. So, I have added you as a friend. Please accept my friend request. I am sending you a private message as well. Respond to the message and provide the system's Service Tag and First and Last Name on the Account so I may access your system records and check for further course of action.
