2.Use a pointing device or the arrow keys to select File > System Information. BIOS and other system information is displayed.

3.To exit Computer Setup, click the back arrow, or use the arrow keys to select File > Ignore Changes and Exit, then follow the instructions on the screen.

4.Select Yes when you are prompted to confirm your choice of Ignoring Changes and Exiting, and the computer will restart.
