Follow These Steps to Access the BIOS on a VAIO® Computer
WARNING!: Other than resetting the BIOS to the default values, making changes to the BIOS is an advanced procedure that can produce unintended results if not done properly. For instance, if you set a Machine Password, and later forget that password, it will require advanced technical support, and possibly service to regain access to the computer.  Go to Product Repair. 
- Power off your computer.
IMPORTANT: If you are having difficulty accessing the BIOS, or are doing so as a step in troubleshooting an issue, it is recommended that you remove all media, or any peripheral devices connected to the computer before trying to access the BIOS.
- Restart your computer.
- At the black VAIO logo screen, press the F2 key repeatedly for 7-10 seconds.
