Introdução
Use this guide to remove the CMOS (Complementary Metal-Oxide-Semiconductor) battery from a Lenovo ThinkPad T14s Gen 1. This is a small, coin-cell battery attached to the motherboard that powers the CMOS chip when the laptop is unplugged. The CMOS chip stores essential system settings, such as the date, time, and BIOS configuration. This ensures that these settings are maintained even when the laptop is powered off. A failing CMOS battery can cause issues such as an incorrect date and time, boot errors, or beeping sounds.
Other notable CMOS battery failure symptoms:
- Hardware drivers are missing or have disappeared
- Can’t connect to the Internet
- Error Messages During Boot
