Search the internet for the complete user guide of the device to understand the steps for setting a password on a Lenovo laptop. Often a unique code is required.
Most manufacturers store passwords in the BIOS/UEFI chip, not in ROM. Removing the battery won’t erase them. You typically need a specific code to reset it. If you contact the manufacturer, they might provide one if your device is covered under warranty or support.
It always helped for me, but I usually just tried it on Dell products. Results might differ with other brands.
