Important notice for replacing a battery pack:

Lenovo ThinkVantage Toolbox has 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 a non-warranty replacement.

For access, disable the battery pack first. Refer to “1000 Disabling the battery pack in the UEFI BIOS” for detailed instructions.

Then remove these FRUs in order:

• Please refer to “1010 Hard disk drive and solid state drive” for detailed instruction.
• Please refer to “1020 Keyboard” for detailed instruction.
• Please refer to “1080 Keyboard bezel assembly with fingerprint reader and audio sub card ” for detailed instruction.

Removal steps of battery pack

When installing:

Make sure the connector is attached firmly to the system board.
