Removing the SIM card:
Some models of the ThinkPad X200, X200s, X200si, X201, X201i, and X201s you are servicing might have the SIM
card that the customer has been installed.
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 71.)
After you finish the servicing, make sure that you insert the card back into the slot firmly.

Some cables used in the ThinkPad X200, X200s, X200si, X201, X201i, and X201s are connected to the flip-lock ZIF
