Legion 7i Pro wakes up every hour from sleep preventing hibernation

[drifting temple]

Model: Legion Pro 7 16IAX10H Gen 10 83F50010US
Describe the issue: Windows wakes up roughly every hour from sleep, preventing hibernation
What have you tried already?: Disabled all wake timers, tested with lid closed, lid open. This is Classic S3 not the new modern sleep mode.
When did it start producing the issue: It's less than 2 weeks old, from the start
Did you install new drivers or software?: Just full update after purchase
Can you provide images/videos to show us the issue: Can't take a video of it, but basically sleep study and powercfg /lastwake show no info. GPT seems to think it's a hardware / EC problem and I agree as Windows has nothing left to cause i t to wake.

I bet it's a usb device. You can try disconnecting peripherals and if you figure out which one, remove it's permission to wake from device manager

[drifting temple]

Nothing was connected to it and I disabled wake on USB

Why don't you try to get it directly Hibernate?

[drifting temple]

Obviously I can, but it takes longer to boot each time so I'd rather it sleeps for a bit before. Also, I'd like it to do what it's supposed to do 🙂

How long does it take for your device to wake up from Hibernate?

[drifting temple]

Didn't measure I guess 10 15 sec

I think your reddit post is the one I commented on recently but figured I would post here as well. I am having the same issue with my Legion Pro 7 that was purchased in the last couple weeks.

[deep stratus]

I'm having the exact same issue and have no peripheral devices connected.

[drifting temple]

Sopey it is the same post yeah - and I have the samae issue. Nothing is plugged in, all wake timers disabled. It basically wakes up to hibernate and instead of hibernating just stays awake and the cycle continues. I think if I set the timer to 2-3 mins to hibernate it doesn't happen - but generally it does

The AIs think it's something to do with the EC and it makes sense. Windows doesn't register any event whatsoever

Maybe some app in the background is not letting it sleep?
What are apps are running in the background?

I wiped the computer and installed a fresh copy of Windows 11, direct from Microsoft, and still had the same issue. For that install, I let Windows grab the latest driver updates but did not install any apps. Then I wiped again and installed a fresh copy of Windows 10; the problem remained. I have tried flashing back to two older bios versions, qvcn38ww and qvcn42ww, and the issue remained. The EC version was re-written when flashing the bios. Right now I am back on the latest version, qvcn44ww.

It's interesting, I found a 2019 post from an MSI forum with the exact same issue. I can set my hibernate to 15 minutes, anything higher than that and the computer wakes from sleep instead of transitioning to hibernate.

I can take a deeper look but I don't really have anything specific running in the background, especially after I did the fresh installs. In both cases I didn't install any new programs that weren't pre-installed on the computer. It's odd that a specific timeout limit and below works, but anything above that 15 minute timeout doesn't. It's almost like something the system relies on for sleep transitions is being put to sleep or stops funcitioning.

[drifting temple]

Exactly that. I didn't go up to 15 but 5 seems to work still. But at some point it simply wakes up to hibernate and instead goes full on.
@deep stratus what do you plan to do about it? I thought about returning at first but I'm going away for several weeks and would rather keep it. Just have to either settle for the short window or manually hibernate, which sucks 🙁

[deep stratus]

I purchased mine for a really solid price ($1,999 along with another $200 back from Rakuten and $120 in Lenovo reward money, for the RTX 5080 model) so I think I'm going to keep it. However, I may consider reaching out to Lenovo and going the warranty route. Trying to decide if that's worth it though. In the meantime, I'm going to set the computer to "never" auto hibernate, closing the lid set as sleep, and the power button set as manual hibernate.

[deep stratus]

I think the thing that bothers me more is that the computer is supposed to auto hibernate after losing 5% battery in sleep, but that's not working properly either. I like it because then I don't lose a ton of battery if I decide to leave the computer in sleep longer than expected.

[drifting temple]

Yeah I feel exactly the same. I'm going to travel with it and handle it when I'm back via lenovo

[deep stratus]

I've been focused on the sleep to hibernate transition based on time, but I decided to test the transition based on battery loss as well. Default Windows behavior puts a computer into hibernate mode if it has lost 5% battery while sleeping. Unfortunately the computer also wakes up when trying to transition to hibernate based on battery loss.

[drifting temple]

Damn. Seems like the whole transition to hibernate just isn't working well at all.

I do not have any sleep to hibernate transition setting. i put my laptop manually to hibernation every time. but recently since last week i've been facing issues of my laptop battery draining to 0% even though it should be in hibernation. not sure what is causing it to wake up and consume the battery. did you manage to find a fix?

i have a Legion Slim 7 2022 model

[deep stratus]

I have not been able to find a fix. I called Lenovo and they want me to send it in to look at it.

[coral tundra]

i'd suggest to not do that. maybe the issue will stop after a few udpates. i remembering facing the same issue for a while back in 2023. but it stopped after a few weeks.

[deep stratus]

Do you know what changed to fix the issue? Was it a bios update, driver, or firmware from Lenovo?
