You can enable the start menu hibernate button in advanced power settings: System -> Power & sleep -> Additional power settings -> Choose what the power buttons do -> Change settings that are currently unavailable -> Check Hibernate. And then get lucky that your laptop wakes up again (mine dies 1 out of 10 times) Edit: sorry, can't read.

No, you can't; that option is disabled. It cannot be checked. I don't know how I can state this more clearly. "Turn on fast startup (recommended)" is checked, and that option is also disabled and can't be unchecked, despite obviously being undesirable.

The checkbox is disabled by default. To enable it you have to click the "Allow advanced options" button at the top of the page.

There is something OS specific: Windows has some setting to wake up when a WLAN connection is available. I had this issue once, that I hibernated it, put it in a bag and went home. On the way it must have picked up some WLAN somewhere and have turned on, while in my bag, while the lid is closed, while hibernated ... And I believe this was the standard setting. I mean, who in their right mind wants their laptop to tur…

Windows keeps waking up for random things, the problem is getting worse with every Windows release and Microsoft keeps removing more and more controls. Just a few days ago I spent hours trying to fix the constant wake-ups. This time it was a waketimer set by the StartMenuExperienceHost.exe process! [1] Microsoft already removed the Power Management tabs in Device Manager for most devices (mouse, etc.). They also remo…

My previous PC would wake up every night around 1am and I could never figure out why. I disabled every single wake timer, all kinds of wake permissions on devices, yet it would always wake up in the middle of the night. The power event in pc management only said "woken by: unknown source".

> Windows keeps waking up for random things Mine will wake the screen and make "device connected" and "device disconnected" sounds while the computer isn't sleeping, regularly. Besides being annoying (I eventually disabled those specific sounds), it probably meaningfully hurts the lifespan of my monitors to power cycle them every five freakin' minutes. I've never been able to figure out what exactly is happening here…

powercfg /lastwake will tell you why the machine woke up. Honestly I'm not sure where else you can find that information.

Generally it doesn't actually tell you why.

lastwake will be blank and the power report will just tell you it changed state but give no reason.

Clickbaity title. It says > Under no circumstances should you leave a laptop powered on and in any sleep/hibernate/standby mode when placed in a bag, backpack, or in an overhead bin. The PC will overheat as a result of that action. Any resulting damage will not be covered by the Dell warranty. Now how a hibernated laptop could overheat..

Submitted title was "Putting a DELL XPS laptop in a bag voids its warranty". We've changed it to a shortened version of what you quoted. Thanks!

I have an XPS 9500 and have found this infuriating. I think there's two separate things going on: As others have noted, S3 sleep isn't supported, only S1 "sleep to idle" sleep. But I don't think this is the direct cause of the overheating. In S1 sleep, the laptop can average something like 900mW of power usage, which is enough to annoyingly knock a few percent off your battery overnight, but not enough to make the la…

I was going to post the exact same thing. I have the 9500; this definitely infuriated me and is mostly solved by installing Linux.

There are still some things that can annoyingly wake it (usually a bluetooth device trying to pair to it); but it's an odd exception versus the 50% chance every time I went to transport my laptop with Windows.

This is one of the main reasons I just returned my XPS 13 9310 and got a Framework instead. The sleep/standby/hibernate stuff is just bad. I don’t know if it is a Dell problem or a Windows problem or what, but it’s terrible.

I’m primarily a Mac user but I haven’t had the same issue with other Windows laptops and the Dell has standby issues in Linux too so it’s just bad. And loud. And hot.

if this comment is serious i strongly suggest you inform yourself about nvme drives. they're absolutely worth their money. i haven't encountered anyone in years that didn't have at least one in their pc/laptop, but if you dont: i strongly suggest you buy one. because writing 30 Gbyte sequentially generally does takes about 10 seconds.

When I got my work laptop, first thing I did is erased its NVMe SSD by writing garbage. It was fast first 30 seconds. In the end sustained write speed was around 60 MB/s. My old HDD works faster. It's fast enough in day-to-day usage, though.

I'll be honest. i haven't encountered a single workload in which i had to write over 90 GByte over 30 seconds (3gbyte sustained for 30 seconds), so you could be correct. Even benchmarks are generally done within 10-15 seconds and my IO is usually constrained by network or CPU at that point.

not sure how that would in any way impact a hibernate routine which would very rarely have to store more then 64gb though.

This is a life-threating design. A high-end "gamer" laptop in a bag powering up unexpectedly could easily catch fire and kill someone. These shenanigans will keep going on until someone dies and a manager or two at Microsoft is sent to jail for criminal negligence.

How can laptop catch fire? CPU throttles itself at 100 C and shuts down shortly thereafter. 100C is not enough to make a fire.

CPUs don't burn, but lithium ion cells don't like being at 100C.

I've seen issues with Modern Standby on my fleet of Lenovo ThinkPad Yoga L13 and L13 Gen 2. Usually everything is fine, but sometimes they get super hot in standby as well. It's like something is keeping the CPU awake but the rest of the hardware is asleep (including the fans). My older units (ThinkPad Yoga 260, ThinkPad Yoga 370, ThinkPad L380 Yoga, ThinkPad L390 Yoga) never had any problem like this because they do…

Not sure if this is related, but I have a 2021 Legion 5 Pro, and even fully powered down it seems to lose a lot of battery power overnight. (Maybe 5%-10% charge, IIRC?)

And this is even after changing the BIOS setting so that it's always-on USB port isn't always on.

I'm really curious where the power is going. Or if the supplied battery has internal leakage issues.
