1010 Battery pack
Important notice for replacing a battery pack:
Lenovo ThinkVantage Toolbox (in Windows 7) 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 the replacement of a physically
damaged battery pack is not covered by the warranty.
