In the unlikely event that a BIOS update is interrupted, it's possible the BIOS might be left in an unusable state. See instructions below, or use the PDF version.

There are two options to perform a BIOS recovery:
- Power Button Menu
- Security Jumper
BIOS Recovery by the Power Button Menu
Download the Recovery BIOS (.BIO) file. Example:
Copy the recovery file (*.BIO) to a USB device.
Plug the device into a USB port of the target computer when it's turned OFF.
Press and hold the power button down for 3 seconds, then release it.
The Power Button menu appears.
Press F4 to start the BIOS recovery.
Wait 2-5 minutes for the update to complete.
The computer turns off when the recovery process is complete, or it prompts you to turn it off.
BIOS Recovery by the Security Jumper
|Note||BIOS recovery using the BIOS security jumper clears trusted platform module keys, Intel® Platform Trust Technology (Intel® PTT) keys, and High-bandwidth Digital Content Protection (HDCP) keys. These keys will not be restored after the BIOS recovery.|
