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