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.
Lenovo provides a diagnostic program to do an automatic battery diagnostic test, which can determine if
the removable battery is defective. A removable 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.
