Hello everyone, I really need your help with this one as I have search on the internet but no luck so far. First of all I need to explain my setup in order to understand what I am trying to do. I have a laptop that I use in my office, that is always connected to power and to an external monitor. I also have a USB hub connected to one of its USB ports where I have connected a wireless keyboard and a fingerprint sensor (since I keep the laptop lid closed all the time). Now the problem I have is the same I had in my previous laptop which was an Asus Vivobook S15 S532FL. I always put my laptop to sleep because I don't want to open the lid every time I want to turn it on. I just want to press the space on the keyboard and my laptop to wake up. The problem I had with the Asus was two actually. The first was that with a slight movement of the mouse the laptop would wake up and the second was that randomly after a few hours the laptop would shut down without reason. I tried literally everything and the solution to my problem was to add the following line in the registry. reg add HKLM\System\CurrentControlSet\Control\Power /v PlatformAoAcOverride /t REG_DWORD /d 0 What this did was to change the sleep mode of my Asus laptop from S0 to S3. This really solved all my problems. The laptop never turned off after going to sleep for a few hours and the only way to wake it up was with the keyboard. And this brings us today. I had to change my laptop and I bought a brand new Samsung Galaxy Book 3 360. Amazing laptop really. Setup is the same. In its USB Type-A port I have connected my hub, in one of its USB C ports I have the power cable and in its thunderbolt port my monitor. But the problems I have right now are exactly the same. A slight movement of the mouse will wake it up and after a few hours of sleep it will turn off randomly. The obvious solution would be to use the same power command I used in my Asus laptop. I did try it but this time my Samsung laptop went crazy. It seems it didn't like this command as I had major problems even turning it on. The power button wouldn't do anything and only after some minutes it would turn on after constantly pushing it. So I had to delete that command and the laptop turned back to its initial behavior. When I write powercfg /a I get the following message. The following sleep states are available on this system: Standby (S0 Low Power Idle) Network Connected Hibernate Fast Startup The following sleep states are not available on this system: Standby (S1) The system firmware does not support this standby state. This standby state is disabled when S0 low power idle is supported. Standby (S2) The system firmware does not support this standby state. This standby state is disabled when S0 low power idle is supported. Standby (S3) This standby state is disabled when S0 low power idle is supported. Hybrid Sleep Standby (S3) is not available. The hypervisor does not support this standby state. And this is where I stand now. I don't know what else to do so if anyone has any idea I would be extremely thankful.
The issue is Modern Sleep will, after an amount of time, will go into Hibernation if it's enabled. (You are mistaking Hibernation as turning off) You need to disable Hibernation completely, and you will stop having this happen.
Hmmm. I haven't thought of that really. Does hibernation cut off power to the USB ports? Because sleep surely does not. And how do I disable hibernate completely?
Hibernation CAN cut off USB power, depending on BIOS setting. As for disabling hibernation, open a CMD prompt with Admin rights: "powercfg -h off"
if you have EuP enabled in the bios, hibernate will shut off power to everything but the power button.
