22. What are three important considerations when installing a CPU on a motherboard? (Choose three.)

Maximum insertion force is applied to the load lever so the CPU is locked in place.
The CPU is correctly aligned and placed in the socket.
The CPU contacts are first cleaned with isopropyl alcohol.
The CMOS EPROM battery is removed prior to installing the CPU.
Antistatic precautions are taken.
The CPU heat sink and fan assembly are correctly installed.

Explanation: The CPU is sensitive to static discharges. Its pins are very delicate and it works at high temperatures, so precautions must be taken. If the CPU has been used in another machine or if the fan is being replaced, you might need to remove the old thermal compound using isopropyl alcohol (not on the CPU contacts). The battery does not need to be removed from the motherboard during the CPU installation. This would cause the saved BIOS settings to be lost. Minimum force should be needed to lock the CPU load lever into place.
