BIOS Upgrade Downloads

ATTENTION! BIOS 70ET67WW v. 1.27 for the TP-70 (T43, R52) dated 2006/10/04 and later require vesafb:nocrtc parameter in vesafb-tng mode. Your console screen will become black without it. NOTE! Firefox or Konqueror users should disable the Use IBM Download Director option when downloading files. NOTE! All Lenovo T, X and R laptops have several bugs in the BIOS that are being actively fixed by Lenovo. For these laptops, BIOS updates are not optional if you find anything to not be working properly, be it the brightness control, or suspend to RAM, or volume keys.

You can check current BIOS and Embedded Controller versions using dmidecode command line tool. For example: bash# dmidecode | grep 70 Version: 70ET69WW (1.29 ) String 1: IBM ThinkPad Embedded Controller -[70HT28WW-1.05 ]- The following table lists direct links to BIOS updates for most Thinkpad Models. Refer to BIOS Upgrade for instructions on how to perform a BIOS upgrade. The FW model column is what actually identifies which sort of firmware (BIOS and Embedded Controller) should be installed in a ThinkPad. Machines with the same firmware model use the same BIOS and Embedded Controller firmware. It can also be found as the OEM table ID in the ACPI DSDT. It is formed by the characters "TP-", plus the first two characters from the BIOS/EC update part number.
