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 following FRUs:
•
"1010 Battery pack" on page 54
•
"1020 Bottom door" on page 55
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:
The Lenovo ThinkVantage Toolbox 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.
