Important notice for replacing a 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 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, remove this FRU:
