Revision : 01 -------------------------------------------------------------------------------- Software name BIOS Update CD (ISO image file for bootable CD) Support models ThinkPad T520, T520i Operating Systems Microsoft Windows 7 32-bit, 64-bit Microsoft Windows Vista 32-bit, 64-bit Microsoft Windows XP Professional SP3 Refer to marketing materials to find out what computer models support which Operating Systems. Version 1.32 -------------------------------------------------------------------------------- WHAT THIS PACKAGE DOES This package provides the ISO image file of UEFI BIOS which is compatible with CD/DVD/BD writing software to create the CD/DVD/BD for the UEFI BIOS update. Hereafter the CD/DVD/BD for the UEFI BIOS update is called as "BIOS Update CD". The BIOS Update CD can boot the computer disregarding the operating systems and update the UEFI BIOS (including system program and Embedded Controller program) stored in the ThinkPad computer to fix problems, add new functions, or expand functions as noted below. For that purpose, it is necessary to have the CD/DVD/BD writing software (with CD/DVD/BD creation function from the ISO image file) prepared separately. Also, any one of the following types of CD-RW, CD-RW & DVD Combo, DVD, DVD Multi, BD or other optical drives should be prepared. (Hereafter these drives are called as "optical drive".) - ThinkPad internal - USB This program is language independent and can be used with any language system. -------------------------------------------------------------------------------- CHANGES IN THIS RELEASE Version 1.32 [Important updates] Nothing. [New functions or enhancements] - Improved system performance when a heavy software was executed with the 65W AC adapter. - Added support for some USB keyboards with a fingerprint reader. - Added support for the option to change product name and version format in SMBIOS. - Disabled keyboarding while the lid was closed to avoid unexpected key input when the computer was held with the lid closed. - Added support for Airplane in-seat power mode of ThinkVantage Power Manager. [Problem fixes] - Fixed an issue that might cause slow system boot. - Fixed an issue where the computer might fail to boot when connected some Smartphones with the USB port. - Fixed an issue where the BIOS Update Utility failed to update the BIOS when DEP (Data Execute Prevention) was enabled. -------------------------------------------------------------------------------- KNOWN LIMITATIONS - After backing up a Windows XP system to a hard drive connected to the e-SATA port through Rescue and Recovery, when attempting to restore the backup image from the e-SATA hard drive through Rescue and Recovery, a blue screen error occurs. Rescue and Recovery can not access the e-SATA hard drive. -------------------------------------------------------------------------------- DETERMINING WHICH VERSION IS INSTALLED There are two ways to check the UEFI BIOS version and BIOS ID. [Checking on Windows] Windows 7/Vista: 1. Click Start, click All Programs or Programs, click Accessories, click System Tools and then click System Information. - or - Click Start, type msinfo32 in the Start Search box and then click msinfo32 in the Programs list. 2. On the System Information window, make sure System Summary is selected in the left side of the window. 3. 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. Windows XP: 1. Click Start, click All programs, click Accessories, click System Tools and then click System Information. - or - Click Start, click Run, type msinfo32 in the Open box and then click OK. 2. On the System Information window, make sure System Summary is selected in the left side of the window. 3. Locate the BIOS version/date line in the right side of the window. "LENOVO BIOS ID (BIOS version), date" will be shown. [Checking on ThinkPad Setup] 1. Turn off the computer. 2. Turn on the computer. 3. While the "To interrupt normal startup, press the blue ThinkVantage button" message is displayed at the lower-left area of the screen, press the F1 key. The ThinkPad Setup menu will be displayed. If a password prompt appears, type the correct password. 4. 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. 5. Turn off the computer. -------------------------------------------------------------------------------- NOTES - You should install the CD/DVD/BD writing software which supports CD/DVD/BD creation function from the ISO image file to create the BIOS Update CD. - To boot the computer from the BIOS Update CD, you should have any one of the following types of optical drives. - ThinkPad internal - USB Any types of other optical device like ExpressCard device are not supported. - To boot the computer from the BIOS Update CD, you may need to change the boot device setting in your ThinkPad computer. Refer to the "Prepare boot device" section in this document. - The contents of the BIOS Update CD can not be shown by Windows Explorer. -------------------------------------------------------------------------------- CREATING THE BIOS UPDATE CD This section assumes to use Internet Explorer and Windows Explorer. Downloading file 1. Click once on the underlined file name. Once this is done, some pop-up windows will appear. 2. Follow the instructions on the screen. 3. In the window to choose Run or Save, click Save. 4. Choose the folder you would like to download the file to and click Save. A different window will appear and the download will begin and complete. Once the download has completed, there may or may not be a message stating that the download completed successfully. Creating BIOS Update CD 5. Prepare a computer with an optical drive installed and a blank CD/DVD/BD disc, and make sure the CD/DVD/BD writing software is installed into the computer. 6. Locate the folder where the file was downloaded. 7. Locate the file ending in ".ISO" that was downloaded, then double-click it. A writing software will open. 8. Follow the instructions on the screen to finish writing and complete creating BIOS Update CD. Finally delete the file saved in the step 4. -------------------------------------------------------------------------------- PREPARING THE BOOT DEVICE Confirm that the BIOS CD is set up as bootable and an optical drive is in the boot device list of your ThinkPad Setup. 1. Power off the computer. 2. Power on the computer. 3. While the "To interrupt normal startup, press the blue ThinkVantage button" message is displayed at the lower-left area of the screen, press the F1 key. The ThinkPad Setup menu will be displayed. If a password prompt appears, type the correct password. 4. Choose "Startup" from the menu. 5. In "UEFI/Legacy Boot", make sure "Both" or "Legacy Only" is chosen. 6. Choose "Boot" from the menu. Note the current boot priority order for restoration later if you need to modify your boot list. 7. In "Boot Priority Order", make sure the following device is on top of "ATA HDD0". - "ATAPI CD0" (when using a ThinkPad internal optical drive) - "USB CD" (when using a USB optical drive) 8. Press the ESC key several times to enter Restart menu and choose "Exit Discarding Changes" to exit from ThinkPad Setup, or press the F10 key to save the new setup and then select Yes. 9.
