When installing: Install the battery pack along the slide rails of the slot. Then
make sure that the battery release lever is in the locked position.
Important notice for replacing a battery pack:
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 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.
