LG gram 15.6 2024 - sleep issues with Win11 Pro

[rabidman]

I bought the above laptop 2 weeks ago from Costco, with Intel CPU, 16GB of RAM and 1TB of SSD. It is fairly nice. This is the first portable PC I have ever owned in 37 years of using them, and 32 years of building them - desktops, obviously.

 

I'm having issues with the power management on this laptop.

 

1) on battery

 

Closing the lid when on battery should make the machine sleep. Even with the lid open, the balanced power plan is supposed to make it sleep at 3 mins of inactivity on battery. It just doesn't seem to go to sleep. My evidence for that is that after a very long (>24hr) journey during which it wasn't used and in my backpack, the battery was at less than 20% when I finally arrived at my destination and started using it.

 

Also, I couldn't easily connect my Sony headphones to my smartphone while in the airplane. The headphones were paired with both the PC and the smartphone. The headphones would always connect to the PC in the overhead bin first, which was presumably not fully asleep.

I kept turning the headphones on and off and manually trying to connect from my phone, and eventually won the race.

 

2) lid closed, plugged in

 

At home, I use the laptop with a USB-C docking station, and the lid closed. The balanced power plan is supposed to make it sleep at 5 mins of inactivity when plugged in. It does not. It remains constantly on 24/7, consuming power. It can be ping'ed, remote accessed into, used locally with the KVM, etc. Forcibly using the start menu and  shutdown->sleep has no effect whatsover.

 

These are serious enough problems that I'm considering returning the laptop to Costco, even though I paid for an upgrade from Win11 Home to Win11 Pro from Keysoff, and the key is now tied to this hardware.

 

Does any LG laptop user have an idea what to do here to let the thing sleep ?

I have similar problems with a 2022 Gram 17 running Windows 11. After some initial fiddling with various settings I concluded that the underlying problem is with Modern Standby https://support.microsoft.com/en-gb/windows/power-efficient-settings-in-windows-11-0d6a2b6b-2e87-4611-9980-ac9ea2175734, https://answers.microsoft.com/en-us/windows/forum/all/how-to-enable-s3-sleep-state-and-disable-modern/507c85fb-977d-4891-b5b1-d302c918ee0e. Effectively there's less sleep, more keeping aware of what's going on (checking emails, etc) and has become a security feature to turn off the screen and lock the computer while the user is away from their desk.

 

I'm also old enough to remember that Windows sleep could never be trusted with people publishing photos of melted parts of computers where they had been put in bags while sleeping. Consequently, I've always used hibernation. SSD speeds means that this is a much faster process than with mechanical hard discs.

Same here, 2023 version, always hibernation to be on the safe side. This is a Windows 11 issue, not a Gram specific issue, you will have similar problems with other Windows laptops. There was a vide on Linus Tech tips about it, it showed that if you put the laptop in sleep while plugged in and then unplugged, it never went to sleep, had to unplug and then put it to sleep. Also when Windows is freshly installed it will keep on indexing and syncing in the background. So the best solution is to activate hibernation. Use the LG Power Manager App to activate hibernation.
