Before I explain about the troubleshooting steps to resolve this issue, let me first give you a brief information about the BIOS Updates.

The BIOS Updates or any Firmware Updates are those Updates which will be installed in the Hardware chipsets.

For, example the BIOS Update will be installed in the BIOS Chipset.

It is required to extreme precaution which installing such Firmware Updates.

It is required to keep the Computer ON while performing these Updates.

If these Updates are not installed successfully or if the Computer is turned OFF during the Installation procedure, this might lead to a Hardware failure.

Hence, for such issues it would be better to get the Unit examined at the Authorized Service Center.

In this case, as the Computer was turned OFF while installing the BIOS Update, the issue might be with the BIOS Chipset.

It is required to get the Unit serviced at the Service Center.

The BIOS Chipset will be flashed to resolve this issue.

This will be done by the trained Technicians at the Service Center.
