Before servicing the computer

Removing the SIM card

Depending on the model, the computer you are servicing might have a SIM card slot. If the customer has
installed a SIM card in the slot, remove it before 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, ensure that you insert the card back into the slot firmly.

1010 Battery pack

Important notice for replacing a battery pack:
• The Lenovo Solution Center program provides an automatic battery diagnostic test that determines if the battery
pack is defective. A battery pack FRU should not be replaced unless this diagnostic test 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 the Lenovo Solution Center program 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.
