This battery powers the laptop's optional metal-oxide-semiconductor (CMOS) chip that stores BIOS settings and passwords. Removing this battery will reset the BIOS settings to factory defaults, including the password. Here's how to do it: Make sure your Lenovo laptop is completely off. Disconnect it from any external power source. Open the back panel of the laptop to access the internal components. This varies by model, so consult the user manual for specific instructions.
If your laptop has a removable battery, remove it. This is usually done by sliding the lock or pressing a button on the bottom of the laptop. For non-removable battery models : If your laptop has a non-removable battery, you should find the battery connector on the motherboard. Carefully disconnect this connector to make sure the laptop is completely off and there is no residual power. The reason we need to remove the main battery is that it can continue to supply power to the CMOS chip even when the CMOS battery is removed. This means that simply removing the CMOS battery may not reset the BIOS settings, including the password, because the main battery continues to power the memory that stores these settings.
