>I've never been able to figure out if this Windows actually doing something useful in "modern standby" like Windows Update, or whether it's a bug. I asked a very similar question a few months ago. The sleep/standby modes were behaving as other people have reported, however, the fact that the battery was draining rapidly in shutdown mode, on a new Dell with a 3 month-old battery with very few cycles, was a cause for concern. Nevertheless, I tried using the CsEnabled trick, which didn't work. Eventually, after troubleshooting BIOS features, applying the latest updates and using powercfg options -- batteryreport, sleepstudy etc. I found a solution, which is a compromise at best. The battery drain was 20% within a few hours. But now with S3 sleep state -- it drains around 8-10% in full shutdown mode over a period of 8-10 hours. A similar drain in Standby is over a period of 15-18 hours. https://answers.microsoft.com/en-us/windows/forum/windows_10-power/how-to-disable-modern-standby-in-windows-10-may/db950560-33da-4a90-8340-b1f181f5efe6#?page=1 https://answers.microsoft.com/en-us/windows/forum/windows_10... https://old.reddit.com/r/Dell/comments/h0r56s/getting_back_s3_sleep_and_disabling_modern/ https://old.reddit.com/r/Dell/comments/h0r56s/getting_back_s...
