Suspend for the X1 Carbon 2018 on Linux
This is short on details. So here are some more: since S0 ( active suspend) became more popular with windows 10, most manufacturers have decided to REMOVE THE CODE from the bios that allows S3 (suspend to ram).<p>Worst case is they left the stubs pretending S3 is supported, so the computer goes to sleep - but never wakes up! Dell, I&#x27;m looking at you!!<p>Workarounds come from redoing the S3 code, mostly in ACPI tables with triggers - for all peripherals.<p>It is a shame, as in S3 most laptops eat less that 1% of the battery per hour, while in S0 such good results require heavy configuration to prevent the &quot;active&quot;  part of active sleep, and make sure the laptop never wakes up until you actually press on the power button. But I guess it is the road to progress, as S0 is more flexible.
