If the computer you are servicing has the SIM card, remove it before you start the servicing.
To remove the SIM card, you need to remove the battery pack first. (See “1010 Battery pack” on page 56.)
After you finish the servicing, make sure that you insert the card back into the slot firmly.

1010 Battery pack
Important notice for replacing a battery pack:
• Lenovo ThinkVantage Toolbox or Lenovo Solution Center ( 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.
