Modifying the hibernation mode

Hi, I've experienced a couple of problems with the default "platform" kernel hibernation mode on my laptop (basically, sometimes the hibernation image fails to resume, leading to a reboot), so I've been testing the steps shown here [1]. In fact, changing to "shutdown" mode does work. There is a way to force systemd to use a specific mode/state configuration by means of creating /etc/systemd/sleep.conf according to man systemd-sleep.conf. I'd add this to the wiki, but I'm not sure which is the most appropriate section to add this information, whether Power management#systemd or Power management#Troubleshooting. --Eugenio M.

I think you can put it under Power_management#Power_management_with_systemd, since sleep.conf isn't mentioned at all in the article yet, and the new section could be expanded and generalized. In any case we're always in time to move it somewhere else if needed. — Kynikos (talk) 07:07, 30 March 2016 (UTC)

Suspend on LynxPoint

I had to disable SLPB and JMC2 too, to avoid instantaneous wakeups from suspend. Should we add this to the list of acpi devices in the "Suspend on LynxPoint" section? Dervomsee (talk) 11:54, 5 March 2017 (UTC)

Is the introduction too long?

The introduction is much longer than other pages, should we move it to its own section such as "suspending methods"? --Fengchao (talk) 06:39, 15 November 2017 (UTC)

Admittedly the introduction is quite lengthy but nevertheless descriptive and it provides the necessary information to understand the following chapters. IMHO I would keep it as it is. -- Edh (talk) 19:13, 15 November 2017 (UTC)
I agree, the problem with separate "introduction" sections is that they would still need to be introduced at the top of the page. -- Lahwaacz (talk) 19:25, 15 November 2017 (UTC)
It is just a style change, no change to actual content. Currently the whole introduction is above the table of contents. When table of contents is expanded, looks bad from my point of view. Add a section will keep table of contents at the top of page. --Fengchao (talk) 03:31, 16 November 2017 (UTC)
Right, I already assumed, that you were just intending to move stuff around without changing the content. Nevertheless I still think that the current introduction is the way to go since it is essential for understanding the following content. However feel free to disregard my opinion. I do not feel to strongly about it. -- Edh (talk) 20:59, 16 November 2017 (UTC)

Suspend then hibernate

To be honest, I find this article somewhat underwhelming when it comes to dealing with modern suspend/hibernation methods.

1. I have personally set up my system to use Intel Rapid Start Technology (IRST), which works great for my purposes, on my machine. Unfortunately it seems that there is virtually no information on IRST on the Arch Wiki.

2. Other than IRST, this page does not make any mention of configuring suspend-then-hibernate (briefly mentioned here).

Both suspend-then-hibernate methods are better than "suspend to both", IMO, since there will be a much shorter delay before going to sleep, and the system will always hibernate after the timeout is reached, rather than when the battery is nearly depleted. This means that you can close your laptop lid, and leave it for a few days yet always be certain that you have a fairly decent amount of battery power left once you resume your system.

Is there a reason this wiki article does not include information on either method, or would it be appreciated if I put time into adding instructions on how to enable them?

Or, in the case of IRST, we should perhaps create a separate page for it? It can then include a list of laptops verified to work with it, since it seems to depend on firmware/BIOS support.
