Removing the SIM card:

Some models of the ThinkPad T400s, T410s, and T410si 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.

To remove the SIM card, you need to remove the battery pack first. (See “1010

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