[Problem fixes] - Fixed an issue where battery might be enabled unexpectedly even when Disable Built-in Battery is set by ThinkPad Setup. -------------------------------------------------------------------------------- DETERMINING WHICH VERSION IS INSTALLED There are two ways to check the UEFI BIOS version and BIOS ID. [Checking on Windows] 1. Hold down the Windows logo key and press X to open a menu at the lower-left area of the screen. 2. Select Control Panel from the menu. 3. Make sure "View by Category" is selected, and select System and Security, select Administrative Tools, and then select System Information. - or - 2. Select Run from the menu. 3. Type msinfo32, and press Enter. 4. On the System Information window, make sure System Summary is selected in the left side of the window. 5. Locate the BIOS version/date line in the right side of the window. "LENOVO BIOS ID (BIOS version), date" will be shown. If you are prompted for an administrator password or confirmation, type your password, or click Continue. [Checking on ThinkPad Setup] 1. Turn on the computer to start Windows. 2. Hold down the Windows logo key. 3. Select Power from the menu. 4. Select Reboot to restart the computer. 5. While the "To interrupt normal startup, press Enter" message is displayed at the lower-left area or lower-center of the screen, press the F1 key. The ThinkPad Setup menu will be displayed. If a password prompt appears, type the correct password. 6. Locate the UEFI BIOS Version line and Embedded Controller Version line. "UEFI BIOS version (BIOS ID)" will be shown on the UEFI BIOS Version line. 7. Turn off the computer. -------------------------------------------------------------------------------- NOTES - 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 [Enabled] 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] - Virtualization - Kernel DMA Protection [Disabled] [Enabled] - Intel(R) Virtualization Technology [Disabled] [Enabled] - Intel(R) VT-d Feature [Disabled] [Enabled] - Secure Boot - Secure Boot [Disabled] [Enabled] - Startup - UEFI/Legacy Boot [Both] [UEFI Only] - UEFI/Legacy Boot Priority [UEFI First] (Not shown) - CSM Support [Yes] [No] (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. -------------------------------------------------------------------------------- UPDATING THE UEFI BIOS Notes: - If your computer runs satisfactorily now, it may not be necessary to update the UEFI BIOS. To determine if you should update the UEFI BIOS, refer to the Version Information section. - You need an AC adapter and a charged battery pack. - Remove the Power-on password prior to updating the UEFI BIOS in the remote deployment environments. Attention: Do not turn off or suspend the computer until the update has been completed. IF YOU DO THAT WHILE THE UPDATE IS STILL IN PROGRESS, THE SYSTEM BOARD MAY HAVE TO BE REPLACED.
