How to Flash the BIOS on an Inspiron
The BIOS runs basic systems when you turn on your computer. The BIOS is stored on a memory chip inside of the computer and runs by a small BIOS battery. It enables the CPU to control and communicate with devices. If you are having a problem with your Dell Inspiron laptop, flashing the BIOS may fix it. It normally isn't needed unless you are having problems.
