"During the upgrading of your computers BIOS, if the computer loses power or
fails to complete the process of upgrading the BIOS, the existing BIOS in
the computer may become damaged. Toshiba HIGHLY recommends that the computer is powered via the AC adapter during the entire BIOS update process.

the failure. If it does not, you'll need to have your computer serviced by a

"Due to the somewhat increased risk of errors updating the BIOS from within
Windows (as compared to using the boot diskette method), it is HIGHLY
recommended that the computer be connected to AC power via the AC adapter, and that the power-save mode is set to 'Full Power' or the equivalent while installing the BIOS."
