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. Removal steps of the battery pack DANGER Use only the authorized battery specified for your computer.
