First, let’s start with a little bit of background on CMOS batteries. A CMOS battery is a small, coin-shaped battery that provides power to your computer’s Basic Input/Output System (BIOS). The BIOS is responsible for booting up your computer and keeping track of time and date. Over time, CMOS batteries can lose their charge and need to be replaced.
If your computer’s time and date are constantly resetting, or if your computer is having trouble booting up, it’s a good sign that the CMOS battery needs to be replaced. Luckily, replacing the CMOS battery on a Lenovo laptop is a pretty easy process.
