Before servicing ThinkPad X1 models

Removing the SIM card:

Some models of the ThinkPad X1 you are servicing might have the SIM card that the customer has installed. If the computer you are servicing has the SIM card, remove it before you start the servicing.

After you finish the servicing, make sure that you insert the card back into the slot firmly.
