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.
