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.
For access, do the following:
1. Disable the built-in battery. See "Disable the built-in battery" on page 34.
2. Turn off the computer and disconnect the computer from ac power and all connected cables.
3. Close the computer display and turn over the computer.
4. Remove the base cover assembly. See "Base cover assembly" on page 34.
