Before replacing any FRU, ensure that you have disabled the built-in battery by doing the following:

1. Turn off the computer. Disconnect the ac power adapter and all the cables from the computer.

2. Turn on the computer. When the ThinkPad logo is displayed, press F1 to enter the ThinkPad Setup

program.

3. Select Config ➙ Power. The Power submenu is displayed.

4. Select Disable built-in battery.

5. Click Yes in the Setup Warning window, then the computer will be turned off automatically. Wait for

three to five minutes to let the computer cool.

Note: After the battery pack is disabled in the UEFI BIOS, it will be automatically enabled when ac power is

reconnected.

Some models you are servicing might have the SIM card that the customer has installed. If the computer you

are servicing has the SIM card installed, remove it before you start the servicing.

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