Question

Over the past week, every time Larry has started his computer, he has noticed that the time is not correct. Larry didn’t consider this a problem because his computer was working properly. However, now Larry has decided that he should investigate why the time is not accurate?
A. The mother board is going bad and needs to be replaced.
B. POST is failing.
C. The CMOS battery is bad and needs to be replaced.
D. The internal time clock is mal-functioning.

Answer 1

Answer:

The reason for this is most likely because the CMOS battery is bad and needs to be replaced.

Explanation:

The CMOS battery is used to power operations that run before the operating system is loaded in a computer.

Answer 2

Answer:

(c) The CMOS battery is bad and needs to be replaced.

Explanation:

In a computer or laptop the CMOS (Complementary metal oxide semiconductor) battery contains small amount of memory space and stores the hardware configuration settings (such as BIOS data and clock/time settings) of the laptop/computer. So if the CMOS battery goes bad, the following are some of the problems that will be encountered on the system;

i. The date and time of the computer will be incorrect.

ii. System may display error messages such as "CMOS checksum error".

iii. The system may turn off and not start because the configuration settings used for starting up the system are not found.

Therefore, to fix this problem, changing or replacing the battery is a way out.
