Software Update and Recovery

The BIOS installation begins.

4.Complete the installation by following the instructions on the screen.

Recovering the BIOS

✎The BIOS recovery procedure requires a USB diskette drive and a formatted diskette.

The BIOS can be recovered if the flash memory is corrupted. Flash memory corruption can occur if the notebook powers down while the BIOS is being updated.

When the notebook is turned on, the boot block portion of the flash memory performs an integrity check on the rest of the BIOS image and enters recovery mode if the image is corrupt.

BIOS recovery can be forced on a non-functioning notebook by turning on the notebook while pressing and holding the Windows logo key + B on the nonfunctioning notebook keyboard until the caps lock light blinks.

To recover the BIOS:

1.If the nonfunctioning notebook is docked in an optional docking device, undock the notebook.

2.Attach the USB diskette drive directly to a USB port on the nonfunctioning notebook. (USB hubs are not supported for BIOS recovery).
