The default config of systemd on Arch suspends to RAM when the lid switch of a laptop is triggered. Unfortunately many modern laptops no longer implement the S3 sleep state in favor of Microsoft's proprietary "Connected Standby" (i.e. the mode that tends to cook laptops in their bags). My new Thinkpad has a toggle in the EFI to re-enable S3, after which suspend to RAM works on Arch with no further configuration necessary.

Do you have any further information about the issue with Connected Standby? It’s one of my favorite features on my Surface.

This was discussed on hn a while ago: https://news.ycombinator.com/item?id=28639952

My old surface also never stayed in suspend reliably.

Thanks!
