1010 Battery pack

Important notice for replacing a battery pack:
Lenovo ThinkVantage Toolbox (in Windows 7) and Lenovo System Toolbox (in Windows Vista and Windows
XP) 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 Lenovo 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 a
physically damaged battery pack is non-warranty replacement.
