Question about Compaq Presario 5686 (402445-003) PC Desktop
When I restart to access the BIOS Menu, I press F10. This is the correct BIOS menu button for my model (Desktop 5686). I know this because I have used the BIOS menu before. Anyway, When it comes up it says setup password, and shows a picture of a key. The only buttons that work are the two enter buttons.
Try removing the CMOS battery, waiting 10-30 seconds, and reinserting it. If the computer displays a "CMOS Checksum Error", the password will be cleared, but the BIOS settings will be lost.

Click the "Start" button found at the bottom left hand side of your desktop. Select "Turn Off Computer" in the "Start" menu options.
Click "Restart" in the "Turn Off Computer" dialog box to reboot your computer.
Watch your computer's reboot display closely. Press "F2" when you see the system keys display at the bottom of the screen, just before the Windows splash screen appears, to access the BIOS panel.
Make any needed changes in the BIOS and hit the "F10" key to save your changes and exit the BIOS. Your computer will complete the startup process and launch Windows.
