NOTES
- If the UEFI BIOS has been updated to version 2.78 or higher, it is no longer
able to roll back to the version before 2.78 for security improvement.
- If the UEFI BIOS has been updated to version 2.75 or higher, it is no longer
able to roll back to the version before 2.75 for security improvement.
- If the UEFI BIOS has been updated to version 2.72 or higher, it is no longer
able to roll back to the version before 2.72 for security improvement.
- If the UEFI BIOS has been updated to version 2.70 or higher, it is no longer
able to roll back to the version before 2.70 for security improvement.
- If the UEFI BIOS has been updated to version 2.69 or higher, it is no longer
able to roll back to the version before 2.69 for security improvement.
- If the UEFI BIOS has been updated to version 2.63 or higher on the system with
the new on-board memory installed, it is no longer able to roll back to the
version before 2.63 with the system.
- Due to Security improvement, once updating UEFI BIOS to this version 2.10
(G6ET66WW) or higher, it is prevented to update UEFI BIOS to 2.09 or older
version.
- If the UEFI BIOS has been updated to version 2.50 or higher, it is no longer
able to roll back to the version before 2.50 because the new 10-digit part
number and serial number format was once installed. The old UEFI BIOS with the
7-digit part number and serial number format can not handle the 10-digit
format.
- Be aware that the OS Optimized Defaults option in the Restart menu of ThinkPad
Setup should not be normally changed. Lenovo recommends to use the factory
default setting for it, as follows.
OS Optimized Defaults
- For Windows 10/8.1/8 64-bit Preload models [Enabled]
- For Windows 8.1/8 32-bit, Windows 7 or Windows XP [Disabled]
To install Windows 8.1/8 32-bit, Windows 7 or Windows XP, the OS Optimized
Defaults option should be [Disabled].
If the OS Optimized Defaults setting is changed, Setup Default by the F9 key
will not load the same default configuration, as follows. Furthermore, by the
condition of Operating System installation, the computer may not be booted due
to the setting change.
If your computer runs satisfactorily now, you have no need to change the OS
Optimized Defaults option. If you need to change the setting, consider well
the effect of the setting change.
Affected Setup menu items :
"OS Optimized Defaults" setting [Disabled] case [Enabled] case
- Security
- UEFI BIOS Update Option
- Secure RollBack Prevention [Disabled] [Enabled]
- Secure Boot
- Secure Boot [Disabled] [Enabled]
- Startup
- UEFI/Legacy Boot [Both] [UEFI Only]
- UEFI/Legacy Boot Priority [Legacy First] (Not shown)
- CSM Support [Yes] [No]
By the OS to be newly installed, you need to change the OS Optimized Defaults
option, and load default configuration.
1. Enter the ThinkPad Setup menu by following steps in [Checking On ThinkPad
Setup] in the DETERMINING WHICH VERSION IS INSTALLED section.
2. Select Restart, then select OS Optimized Defaults and press Enter.
3. Select the following setting and press Enter.
[Enabled] (for Windows 10/8.1/8 64-bit)
[Disabled] (for Windows 8.1/8 32-bit, Windows 7 or Windows XP)
4. Press the F9 key to load default configuration.
5. Select Yes.
6. Press the F10 key to save default configuration and exit.
7. Select Yes.
The computer will be restarted automatically.
- Lenovo recommends to install the USB 3.0 driver for Windows (Version 1.0.4.225
or higher) prior to updating the UEFI BIOS. Because the UEFI BIOS requires the
modification in the USB 3.0 driver to fix USB 3.0 related issues.
(Caution)
If both the Secure Boot option is Enabled and UEFI Secure Boot in the Main
menu of ThinkPad Setup is shown as Off, restoring Factory Keys is needed. Do
the following to restore Factory Keys.
1. Enter the ThinkPad Setup menu by following steps in [Checking On ThinkPad
Setup] in the DETERMINING WHICH VERSION IS INSTALLED section.
2. Select Security, then select Secure Boot.
3. Select Restore Factory Keys, and press Enter.
4. Select Yes to restore Factory keys.
5. Press the F10 key to save configuration and exit.
6. Select Yes.
The computer will be restarted automatically.
- To enable 30 Day standby feature of ThinkVantage Power Manager, the computer
has to disable waking computer by network adapters and USB devices. Uncheck
the checkbox next to "Allow this device to wake the computer" in the Power
Management tab for each device in Device Manager.
