To remove the time-of-day battery, complete the steps in this procedure.

1. Ensure that you have the electrostatic discharge (ESD) wrist strap on and that the ESD clip is plugged into a ground jack or connected to an unpainted metal surface. If not, do so now.
2. Grasp the time-of-day battery and pull it out of its slot in location P1-C1-E1 on the service processor card as shown in Figure 1.
   Attention: While removing the battery, do not use a metallic tool to disengage it from its slot.

   CAUTION:

   • After removing the failed time-of-day battery, do not:
     • Burn or charge the battery (to avoid possible explosion as the battery contains lithium).
     • Throw or immerse the battery in water.
     • Heat the battery to more than 100 ⁰C (212 ⁰F).
     • Repair or disassemble the battery.
   • Exchange the battery only with the IBM-approved part. Recycle or discard the battery as instructed by local regulations. In the United States, IBM® has a process for the collection of this battery. For information, call 1-800-426-4333. Have the IBM part number for the battery unit available when you call.
   When you remove the time-of-day battery, ensure that you also did not loosen the service processor card. Press the service processor card in to be sure that it is not loose.
