1110 Io Bracket - Lenovo 21D8 Hardware Maintenance Manual

The Vantage app provides an automatic battery diagnostic test that determines if the built-in battery is
defective. A built-in battery FRU should not be replaced unless this diagnostic test shows that the battery is
defective. The only exception to this is if the built-in battery is physically damaged or a customer is reporting
a possible safety issue.
If the Vantage app is not installed on the computer, the customer should download and install the program to
diagnose the built-in battery, before getting a non-physically damaged built-in battery replaced. Note that the
replacement of a physically damaged built-in battery is not covered by the warranty.
