Your Dell Inspiron 1501's BIOS controls the basic functions or your laptop. It is the "Basic Input/Output System" that runs the clock and mediates between the operating system and the hardware. According to the Inspiron 1501 owner's manual, a small button battery preserves the BIOS settings when the main battery is empty. You may need to reset the BIOS if you have made changes to the settings that prevent your laptop from operating properly.
