Be sure to follow all prerequisites before downloading and installing a BIOS update.
IMPORTANT: To reduce the risk of damage to the computer or an unsuccessful installation, download
and install a BIOS update only when the computer is connected to reliable external power using the AC
adapter. Do not download or install a BIOS update while the computer is running on battery power,
docked in an optional 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.
Do not shut down the computer or initiate Sleep.
Do not insert, remove, connect, or disconnect any device, cable, or cord.
