Installation Instructions ------------------------- NOTES: - As written on LCCM Compatibility and Configuration Guide, remove the Power-on password prior to flashing the BIOS in LCCM (LANClient Control Manager) environment. - You need an AC adapter and a charged battery pack to update the system program. - If your computer is attached to any kind of port replicator, turn off the computer and detach it before proceeding. (Except the ThinkPad UltraBase X2 option. You can attach the option and use the embedded diskette drive in it.) - Make sure the System Program Service Diskette is write-protected. 1. Print these instructions or display on another computer. 2. Firmly connect the AC adapter to the computer. 3.

Press the Esc key to return to the menu. 6. Select Update system program and follow the instruction on the screen. Note: If you are updating the system program through the external diskette drive (USB type, not the diskette drive in the ThinkPad UltraBase X2), it will take quite a long time to complete reading the system program file, but it is normal. Continue the update. Warning: 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, do the following to make the changes effective. 7.
