Before servicing ThinkPad T510, T510i, and W510
Table 9. Removal steps of SIM card
Some models of the ThinkPad T510, T510i, and W510 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
Battery pack" on page 87.)
After you finish the servicing, make sure that you insert the card back into the slot
firmly.
