It addresses a potential issue which might cause a system to exhibit erratic behavior such as a system hang, reboot, blue screen or Kernel Panic (Linux), and may also cause in-progress system operations (e.g. file, I/O) to fail. The possibility of this behavior is believed to be limited, but Lenovo strongly recommends that customers install this update as soon as possible to prevent the possibility of the issues listed above. The ID of the affected microprocessors is "F29" for the ThinkPad G40. * Determining Processor ID There are several ways to determine the processor ID: 1. Go to the Access IBM Predesktop Area (hold down the Access IBM key when the IBM logo screen is displayed during the power up sequence). Click on the "Information" box on the left. (The "CPU id" is in the third box down on the right.) 2. Use the Microsoft "System Information" tool. Click Start, select Programs, select Accessories, select System Tools, then click System Information. The first screen displayed with this tool has processor information. The processor ID identifies the Family, Model and Stepping of the processor. For example, a processor with an ID of "F29" will have the following entry. Note that the "F" is translated to a "15" by this tool. "Processor x86 Family 15 Model 2 Stepping 9 GenuineIntel .." 3. DMI information. The processor ID is presented in the DMI (Desktop Management Interface) Type 4 structure. There are various tools (DMI browsers) available to view this information. 4. If you have a Windows installation that for some reason does not have the "System Information" tool, a utility to display the processor ID can be obtained from Intel at the following URL: http://support.intel.com/support/processors/tools/ frequencyid/ 5. System administrators may wish to refer to the following URL for an example of a Microsoft script file that extracts (among other things) the processor ID. http://www.microsoft.com/technet/community/scriptcenter/ compmgmt/scrcm73.mspx <1.15 - 1TETA0WW> - (New) Added new menus in the BIOS Setup Utility. ("Timer Wake with Battery Operation" in "Power", "Require password after hibernate" in "Security" then "Password") <1.17 - 1TETA2WW> - (Fix) System may shutdown at password is prompted without waiting one minute in wake up from hibernation if power on password is set and if "Require password after hibernate" option in the BIOS Setup Utility is enabled. <1.18 - 1TETA3WW> - (New) MPU microcode update. <1.19 - 1TETA4WW> - (New) Enhancement of security function on password process <1.20 - 1TETA5WW> - (Fix) POST error appears on power-on, just after power off at BIOS password prompt with a USB floppy drive or USB HDD. <1.21 - 1TETA6WW> - (New) The security process at reboot by WOL was updated. Installation instructions ------------------------- Notes: - You need an AC adapter and a charged battery pack to update the system program. - If your computer is attached to any kind of docking station or port replicator, turn off the computer and detach it before proceeding. 1. Print these instructions or display on another computer. 2. Firmly connect the AC adapter to the computer. 3. Insert the write protected System Program Service Diskette into the diskette drive and turn on the computer. 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 system program and follow the instruction on the screen. Attention: 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 replaced. After the update has been completed, do the following to make the changes effective. 7. Make sure there is no diskette in the diskette drive, then turn on the computer. 8. While the To interrupt normal startup, press the blue Access IBM button message is displayed at the lower-left of the screen, press the Access IBM button. Select Start setup utility. If you have set a supervisor password, the BIOS Setup Utility menu appears after you enters the password. 9. Verify the BIOS Version and date. BIOS information ---------------- Each version of the System Program Service Diskette contains the following system program (BIOS). The BIOS Version and the date can be viewed by running ThinkPad Configurator from your operating system and selecting the System Information button or by invoking the BIOS Setup Utility. 1. Make sure there is no diskette in the diskette drive, then turn off the computer. 2. Turn on the computer. 3. While the To interrupt normal startup, press the blue Access IBM button message is displayed at the lower-left of the screen, press the Access IBM button. Select Start setup utility. If you have set a superviser password, the BIOS Setup Utility menu appears after you enters the password. 4. The BIOS version and date are displayed on the first screen of the BIOS Setup Utility.
