Important notice for replacing a removable 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 Solution Center program provides an automatic battery diagnostic test that determines if the
battery pack is defective. A battery pack FRU should not be replaced unless this diagnostic test shows
that the battery is defective. The only exception to this is if the battery pack is physically damaged or a
customer is reporting a possible safety issue.
If the Lenovo Solution Center program is not installed on the computer, the customer should download and
install the program to diagnose the battery pack, before getting a non-physically damaged battery pack
replaced. Note that the replacement of a physically damaged battery pack is not covered by the warranty.
