to look at the new patch set (#3).

ec/lenovo/h8/acpi: Support pulsing LEDLOGO on Haswell ThinkPads
The name LEDLOGO comes from schematics. It's the red indicator, embedded in the dot of the 'i' of the ThinkPad logo on laptop's lid.
In vendor firmware, this led starts fading in-and-out, or, in other words, pulsing, when laptop is put to S3. It helps to determine whether the laptop is in S3 just by taking a look at the logo.
As of now, coreboot doesn't do anything with this particular indicator, it's always in enabled (on) state, whether it's in sleep mode or not, which is not convenient.
This patch fixes it.
Tested on T440p.
