T520 4242xxx Intel ME Management Engine Firmware update does not work

2017-05-31, 15:50 PM

For Lenovo T520, Type 4242xxx an Update for the Intel ME Firmware is offered. There are to links to the update, with the same aim:



Gives the Link to package 83rf45ww.exe 


The same file is linked here for T520


It is described as Version in the download page for Intel Managmenent Engine Firmware

The delivered Package 83rf45ww.exe starts an installer mentioning an earlier version 7.1.xx.1zzz, which should not solve the intel ME security issue (last number has to be bigger than 3000).

The update does not work. If you take a look at the unpacked package content under standard-path C:\DRIVERS\WIN\ME it contains a *.bin dated 22.09.2014 (dd.mm.yyyy)
If you run fwupdlcl.exe from commandprompt with administrative rights it shows you a lower version as well.


Please check the provided update and provide an appropriate update. Thank you.
