Before servicing ThinkPad X300 Removing the SIM card: Some models of the ThinkPad X300 you are servicing might have the SIM card that the customer has been installed.

After you finish the servicing, make sure that you insert the card back into the slot firmly. Notice on disconnecting the cable from flip-lock ZIF connector: Some cables used in the ThinkPad X300 are connected to the flip-lock ZIF connectors. When disconnecting the cable from those connectors, do as shown in this figure. 1 2 60 ThinkPad X300 Hardware Maintenance Manual
