On my E540 I use System Update app from Lenovo. The app repeatedly tells me to update Intel Management Engine Interface 8/10. I've done so 5 times, each time the app says the installation was successful. What gives?
It seems to be a problem with the system update application from Lenovo, it might be that is not reading the installation lines and this is why keeps detecting new updates for the management engine.
Please check with Lenovo for possible workarounds or fixes for your program.
