The CMOS battery has failed is the most likely problem when you boot your computer, it hangs after asking you for the current time and date.
Complementary metal–oxide–semiconductor could be a kind of metal–oxide–semiconductor field-effect transistor (MOSFET) fabrication method that uses complementary and symmetrical pairs of p-type and n-type MOSFETs for logic functions.[1] CMOS technology is employed for constructing integrated circuit (IC) chips, including microprocessors, microcontrollers, memory chips (including CMOS BIOS), and alternative digital logic circuits. CMOS technology is additionally used for analog circuits such as image sensors (CMOS sensors), data converters, RF circuits (RF CMOS), and extremely integrated transceivers for many varieties of communication.
The complementary MOS (CMOS) process was originally planned by Frank Wanlass at Fairchild Semiconductor and conferred by Wanlass and Chih-Tang Sah at the Conference the next year in 1963. Wanlass later filed a US patent of 3,356,858 for CMOS electronic equipment and it absolutely was granted in 1967. RCA commercialized the technology with the trademark "COS-MOS" within the late 1960s, forcing other makers to search out another name, resulting in "CMOS" turning into the quality name for the technology by the first 1970s.
