You can tell if a Lenovo laptop battery is bad if it doesn't hold a charge for long, drains quickly, or the laptop only works when plugged in. You might also see battery error messages or a "replace battery" warning in Windows or Lenovo Vantage. Additionally, the battery status in the system settings may show "Battery not detected" or "Battery needs replacement."
