You can check the current BIOS and ECP versions on your ThinkPad by using dmidecode. For example:
# dmidecode -s bios-version
6DET52WW (3.02 )
# dmidecode -t 11
# dmidecode 3.1 Getting SMBIOS data from sysfs. SMBIOS 2.4 present. Handle 0x001D, DMI type 11, 5 bytes OEM Strings String 1: IBM ThinkPad Embedded Controller -[7XHT22WW-1.04 ]-
Showing BIOS version 3.02 (6DET52WW) and ECP version 1.04 (7XHT22WW).
Alternatively you can grep the information from dmesg
$ dmesg | grep "ThinkPad BIOS"
