The Dell Vostro 1500 is a mid-level, multipurpose laptop designed primarily for small businesses and professional users. A likely used feature of this laptop is the ability to set a BIOS password, which prompts the user to enter a series of characters to allow entry into the operating system.
The Basic Input/Output System is a program which is built into a computer system motherboard and offers access to the setup and configuration of the hardware. During the initial boot phase, the BIOS is accessed and acts as the controller for processes such as booting into the operating system.
Two ways exist to reset the Bios/CMOS battery in laptops like the HP Pavilion N5415 that have the CMOS battery physically glued or soldered to the motherboard. The first is by removing power to the Bios causing it to restore to defaults without a set password or by using a program to identify the password.-->
