Updating the BIOS will require a USB flash drive to store the BIOS information on during the update. To perform the update to the BIOS:

1. Go to Toshibas Homepage and download the latest BIOS for the notebook.
2. Extract the files from the downloaded zipped BIOS file.
3. In the Dos_Flash folder, rename the BIOS file from xxxxx.fd to SACPHO10AP.FD, in all capital letters.
4. Copy SACPHO10AP.FD to a (bootable) USB flash drive
5. Ensure that the AC adapter is plugged in.
6. Insert the USB flash drive into a USB port.
7. Press and Hold down the ALT-F or WINKEY-F keys together and press the power button.
8. When the unit's power light comes on wait a few seconds and release keys.
9. After the keys have been released the power light will start to blink.
10. During the BIOS update process the display will be blank.
11. Let the unit run and after approximately 1 to 7 minutes, the unit should reboot and the BIOS will be updated.

If the unit fails to reboot, or the BIOS was not updated sucessfully, try the steps again. If the unit continues to fail to reboot, the unit may need service.
