Important notices 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 Lenovo Solution Center program provides an automatic battery diagnostic test that determines if the
battery is defective. 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 Lenovo Solution Center 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.
For access, remove this FRU:
• "Removing ThinkPad Pen Pro (for ThinkPad X1 Yoga Gen 8)" on page 64
• "1010 Base cover assembly" on page 64
