You are the technician on call at Certkiller .com. A client complains that her time and date on her
desktop computer is constantly wrong, even though she resets it. Which of the following should
repair the problem?
A.
A new system board.
B.
A hard disk.
C.
An installation disk to re-install her operating system.
D.
A new CMOS battery.
Explanation:
These symptoms indicate that the system’s CMOS is losing the time, date, and hard disk settings.
The CMOS is able to keep this information when the system is shut off because there is a small
battery powering this memory. Because it is a battery, it will eventually lose power and go dead.
Incorrect answers:
A: The symptoms exhibited are not characteristic of a faulty system board.
B: A faulty hard disk in need of replacement does not show the symptoms described in the
question.
C: It is not the operating system that is responsible for the symptoms that the client is
experiencing.
