4. Disconnect all cables from the motherboard, including those for the keyboard and
mouse.
5. Remove all add-on cards.
6. Install a CPU, a heatsink*, and connect the power LED to the motherboard. Check all
jumper settings as well. (Make sure that the heatsink is fully seated.)
7. Use the correct type of onboard CMOS battery as recommended by the manufacturer.
To avoid possible explosion, do not install the CMOS battery upside down.
