Other key symptoms of a failed CMOS battery include problems in the boot process and constant beeping noise from the motherboard. Figure (a) shows an inverter circuit using PMOS logic (not to be confused with a power inverter).MOSFET Q 1 acts as an active load for the MOSFET switch Q 2.For the circuit shown, GND and V DD respectively represent a logic ‘1’ and a logic ‘0’ for a positive logic system. But if your computer is showing the wrong system time or date after a reboot or you are facing hardware compatibility issues, it may be time to replace the CMOS battery. The PMOS logic family uses P-channel MOSFETS. Most CMOS batteries last anywhere between two to 10 years, depending on the computer usage. And since the removal or failure of CMOS battery has traditionally been associated with clearing CMOS data, modern motherboards also reset UEFI settings when CMOS battery fails. That said, CMOS batteries are still used to keep time in your computer. ![]() The non-volatile memory can retain data even without applied power. However, the modern UEFI motherboards use a non-volatile memory or NVRAM to store UEFI configuration data. An NMOS transistor consists of n-type source and drain and a p-type substrate. What is NMOS NMOS (nMOSFET) is a kind of MOSFET. CMOS technology uses less energy to operate at the same output and produces less noise during operation.
