Before servicing the computer
Carefully read this topic before servicing the computer.
Removing the micro SIM card
Some models you are servicing might have a micro SIM card that a customer has installed. If the computer
you are servicing has a micro SIM card installed, remove it before you start the servicing.
To remove the micro SIM card, you must remove the battery pack first. See “1010 Battery pack” on page 72.

After you finish the service, insert the card back into the slot.

Important notices for replacing a battery pack
Attention: Lenovo has no responsibility for the performance or safety of unauthorized batteries, and
provides no warranties for failures or damage arising out of their use.
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 on the computer, the customer should download and
install the program to diagnose the battery pack, before getting a non-physically damaged battery pack
replaced. Note that the replacement of a physically damaged battery pack is not covered by the warranty.
