Downloading a BIOS update

docking device, or connected to an optional power source. During the download and installation, follow these
instructions:
Do not disconnect power on the computer by unplugging the power cord from the AC outlet.

computer. Make a note of the date, name, or other identier. You may need this information to
locate the update later, after it has been downloaded to your hard drive.
b. Follow the on-screen instructions to download your selection to the hard drive.
Make a note of the path to the location on your hard drive where the BIOS update is downloaded.
You will need to access this path when you are ready to install the update.
