> Windows keeps waking up for random things, the problem is getting worse with every Windows release I resorted to removing the power plug from the PC every evening after it kept turning itself on during the night semi-randomly. It was in "suspend to disk" mode, whatever that is in more technical power-save jargon terms, not just "suspend-to-ram". I spent a significant amount of time going through Windows event logs to find what caused the wake-ups, fixed some, others were too broad to do anything about it. The settings are useless. So is the Microsoft help forum. I won't even try to ask Dell (Dell 8500 PC), they are only good at sending replacement hardware but unable to answer anything related to software (as long as they do the former I came to accept the latter). I too had my (also Dell) laptop overheat after I had suspended it, thinking it was turned off. It was very hot when I took it out of the bag later, fortunately it was just in time. It seems this mishap caught a lot of people off guard.

Before you put it sleep activate Airplane mode. Hopefully it will disable wake ups.

What REALLY pisses me off is that if I put my computer to sleep for the night, and windows then runs some updates, it doesn't put the computer back to sleep! Why not? Why should it run all night instead of going back to sleep, what the hell microsoft

I've seen the same behavior on a 10+y.o. system with Win11 on it. I started unplugging it every night and re-plugging it every day when I went to use it. Funny thing has happened in the meantime, since getting a MB Air I haven't plugged it in for like 2 months now...

> I resorted to removing the power plug from the PC every evening after it kept turning itself on during the night semi-randomly. It was in "suspend to disk" mode, whatever that is in more technical power-save jargon terms, not just "suspend-to-ram". In "Suspend to RAM", the RAM is kept powered when the computer is shut down, and thus doesn't have to be touched on wake, but it means the computer has to stay powered the whole time. In "Suspend to disk", the entire RAM is written to disk (which can take some time especially with an HDD) then the computer shuts down entirely, on wake the OS will restore RAM from disk before resuming. The need to read data back from disk to RAM makes the wake costlier, but because everything's on disk the computer can be completely shutdown. The two can be combined into mode where data is written to disk (making going to sleep slower) then the computer enters "suspend to RAM" mode. If the computer is resumed normally it is restored from RAM, but if the computers suffers power loss it's restored from disk. Either way the computer doesn't have to boot from scratch and all the working set should be recovered. IIRC it's the default behaviour for macOS laptops, microsoft calls it "hybrid sleep".
