1090 Battery pack

For access, remove these FRUs in order:

• "1020 Hard disk drive or solid state drive assembly" on page 54
• "1030 Keyboard" on page 55
• "1040 Top case assembly" on page 58
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 Lenovo 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 part.
Note: Before removing the battery, insert a straightened paper clip into the emergency reset hole to reset the
computer.
