1. Print these instructions or display on another computer.
2. Firmly connect the AC adapter to the computer.
3. Insert the write protected Embedded Controller Program Service Diskette into the diskette drive and turn on the computer.
4. Select Read this first from the menu and carefully read the information that appears.
5. Press the Esc key to return to the menu.
6. Select Update Embedded Controller Program and follow the instruction on the screen.
   
   Note: If you are updating the Embedded Controller Program through the external diskette drive (USB type, not the diskette drive in the ThinkPad UltraBase X3), it will take quite a long time to complete reading the Embedded Controller Program file, but it is normal. Continue the update.
   
   Attention: Do not turn off or suspend the computer until the update has been completed. IF YOU TURN OFF OR SUSPEND THE COMPUTER WHILE THE UPDATE IS STILL IN PROGRESS, THE SYSTEM BOARD MAY HAVE TO BE REPLACED.
   
   After the update has been completed, the system is automatically turned off.
