Learn to test your computer
for a bad CMOS battery.
Your computer's CMOS (Complimentary
Metal-Oxide Semiconductor) is a small, battery-powered chip built into the
motherboard. It stores basic data instrumental to your computer's overall
performance. It primarily stores your computer's internal clock settings, and
allows some of your computer's hardware to communicate with the operating
system. When the CMOS battery goes bad, it can cause some of your hardware to
behave erratically.
