Battery pack removal and installation

Important notice for replacing a battery pack:
Lenovo ThinkVantage Toolbox have an automatic battery diagnostic that determines if the battery pack is defective. A battery pack FRU should not be replaced unless this diagnostic 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 ThinkVantage Toolbox is not installed in the computer, the customer should download this program before a non-physically damaged battery pack is replaced. Note that a physically damaged battery pack is non-warranty replacement.


Use only the battery specified in the parts list for your computer. Any other battery could ignite or explode.

Unlock the battery latches [1]. Holding the battery latches in the unlocked position, remove the battery pack in the direction shown by arrow [2].


When installing: Install the battery pack in the slot, and then make sure that the battery latch is in the locked position.
