John Ratsey Posted October 26, 2022 Share Posted October 26, 2022 I'm getting frustrated by Modern Standby on my LG Gram 17 (2022) with Windows 11. When I tell the computer to Sleep then the fan keeps running and running. In reality, it's not sleeping at all but just turns off the display and keeps everything running. One consequence of this is the risk of overheating when the screen is closed and heat dissipation is less effective. Battery drain is also much higher than the traditional sleep. I wonder if Modern Standby was created for desktop computers and has been inflicted on notebooks without proper thought. The traditional low power sleep uses low power state S3. However, when low power state S0 is enabled in the BIOS then other sleep states are automatically disabled. Using a registry entry to disable S0 seems to work when telling the computer to sleep - it quickly goes quiet - but reboots when told to wake up. I've also tried disabling S0 in the BIOS and Powercfg /a shows that this enables the other sleep states. However, the reboot on wake problem still happens. There is some potentially relevant discussion here but I think the problem is if wider interest to notebook users. I suspect that something else in Windows needs to be changed to ensure trouble-free waking when Modern Standby is disabled.Ideally, S0 would be disabled before Windows is installed and Windows would then configure itself accordingly. Has anyone else had this problem and managed to solve it? 1 Link to comment Share on other sites More sharing options...
