1010 Battery pack
Important notice for replacing a battery pack:
The Lenovo ThinkVantage Toolbox (in Windows 7), Lenovo System Toolbox (in Windows Vista and Windows
XP), and Lenovo Solution Center (in Windows 7) 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 or Lenovo System 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.
