Important notices for replacing a built-in battery
Attention: Lenovo has no responsibility for the performance or safety of unauthorized batteries, and
provides no warranties for failures or damage arising out of their use.
The Lenovo Vantage program 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 Lenovo Vantage program 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.
