You should specify the following: 1. how this password got there (whether it's set by a user or original from the factory) 2. what kind of password do you mean (usually there are more than 1 of them - what is the exact name of this password) 3. If possible, post the image you see when you open the BIOS settings screen The service code/tag you provided currently only provides the following information: Dell HDD Serial Number (old): yyyyydvv *For Dell - Type password then hold Left Ctrl & press Enter twice. NB! This may be wrong, because it is for HDD and it is the default code for old computers.
How can I post image when I power on laptop it’s comes in screen that says system is protected by a password authentication system.......No hdd in system
You need to revert the BIOS to A15 to use the password generator...it contains the old master password algorithm. Get a USB stick (formatted FAT32) and put the D830 A15 BIOS HDR file on it. Then perform the HDR recovery method to revert the BIOS. Then generate the password online.
