Hello,
I have the same behaviour (the screen doesn´t light after suspension) with Coreboot + striped ME (latest) and _kernel 4.10.9_.
But with an older kernel (4.4.5) it recovers correctly.
I didn´t try to first boot with power supply attached..
I think it was kernel related not a coreboot or ME_cleaner problem
Best regards,
Elisenda

Hi Nicola Corna,
Recently I have observed some weird phenomina related to suspension on my x230 with coreboot and ME cleansed with latest me_cleaner:
- If its first boot after flash is done on a powered expansion dock, it has a high probability to fail to light the screen during recovery from suspension.
- If its first boot after flash is done with battery power, the screen will be lit during recovery if usb3 ports has never been used before suspension, otherwise it 100% fails.
- If its first boot after flash is done with a power supplier directly attached, the recovery from suspension can always light the screen.
Such "settings" are completely determined with how the first boot after flash gets powered, and are memorized across power cycles, but unrelated to where later boot is done, nor whether expansion docks are used after the first boot is DONE.
I guess it may be related to the MRC cache.
