Actually CMOS is not a battery ,it is a technology which is used to construct Integrated Circuit. CMOS stands for Complementary Metal Oxide Semiconductor. This technology is basically used in microprocessor, micro-controller,RAM ,different logic circuit.
To check the CMOS battery we have to take following steps:
To check the CMOS battery we have to take following steps:
- Remove the CMOS battery from the motherboard.
- Set the multimeter in DC voltage mode
- Put the red probe on +ve side (mentioned on the CMOS battery) and black probe on opposite side of the CMOS battery.
- If the output voltage shown is grater than 2.5 volts on multimeter then it is OK otherwise replace the battery.
