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: • "1010 Removable battery" on page 57 • "1020 Base cover assembly" on page 57 Removal steps of the built-in battery or dummy built-in battery DANGER Use only the authorized battery specified for your computer.
