    OK i will need your OS (XP,VISTA,ect..). or try this below:

    1. Restart your computer.
    2.At the first text on the screen or when the Dell™ logo appears, tap until the message Entering Setup appears.

    Some older Dell computers use an alternate key sequence instead of to enter System Setup. These key sequences include:

    *
    *
    * (laptop computers only)
    * (laptop computers only)

    Your computer is locked with a Power on Password set in the bios. With the service tag and -595B you can call Dell and they can give you a bios master password that will clear all bios password and let you have access to bios setup. You can also use MIT Unlock Bios

Please help me i forget bios password in my laptop dell model is 1525 how can i open it


To reset the BIOS password in your Dell Inspiron 1525 you would first need to disassemble the laptop and remove the CMOS battery for 30 seconds and put it back in. You can do this by following the service manual below provided by Dell.

Please be aware that this will take some technical knowledge to do, making a mistake here can be fatal to the operation of your system. I urge you, if you are not comfortable following any of these steps, take it to a local professional.
