BIOS Upgrade Downloads

ATTENTION! Lenovo silently recalled the 1.11 BIOS for the X60 and T60. No information about this recall is known, they just reverted the BIOS download page, reverting changelogs. NOTE! Firefox or Konqueror users should disable the Use IBM Download Director option when downloading files.

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.
