Click here for instructions and limitations on downloading and creating the diskette.

Use the links below to obtain the BIOS and Embedded Controller files in other file formats:

• Embedded Controller Non-Diskette
• BIOS Non-Diskette
• BIOS Diskette

• (New) Enhance safety with an unsupported battery.
  

• To determine if you should update the Embedded Controller Program, refer to the Summary of changes section.
• You need an AC adapter and a charged battery pack to update the Embedded Controller Program.
• If your system is attached to any kind of port replicator, turn off the system and detach it before proceeding. (Except the ThinkPad UltraBase X3 option. You can attach the option and use the diskette drive option in it.)
• Make sure the Embedded Controller Program Service Diskette is write-protected.
• Remove the Power-on password prior to updating the Embedded Controller Program in RDM (Remote Deployment Manager) environment or similar environment.

1. Print these instructions or display on another system.
2. Firmly connect the AC adapter to the system.
3. Insert the write protected Embedded Controller Program Service Diskette into the diskette drive and turn on the system.
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 system until the update has been completed. IF YOU TURN OFF OR SUSPEND THE SYSTEM 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.
   
   

To enter the BIOS Setup Utility:
