X240: slow POST



My X240 needs 17s until the first message appears on the screen.
Usually this takes about 2s (no matter whether Quick Boot is on or off).
Everything else works fine.


By searching for similar problems I found about a dozen threads covering the same topic (for other models), but no solution.


The laptop has the newest BIOS (2.40). Unfortunately I can not test any downgrade, because of security reasons. I tried to force a downgrade by extracting the BIOS files and by using a generic flash tool, but I did not succeed. If someone knows how to do that, please let me know.


Resetting the BIOS did not help.
In the last few days I tried almost every combination of BIOS settings, but no success.


I should mention, that the Intel AMT has been configured to be permanently off.


I should also mention, that for testing purposes I'm using a minimalistic setup: the naked mainboard just with the CPU cooler, a DRAM module, and a SSD is hooked onto a docking station.


Any help greatly appreciated.
