If you make this mistake, you will lose laptop battery power quickly
A Microsoft employee recreated this behavior with a little test and wants to report it to his colleagues on the Windows team as a bug. So, if you want to avoid running into the modern standby problem, you should always unplug the power cord before shutting down your laptop.
In other words: if you unplug the power cable while your laptop is in sleep mode, it is active on the network and this can drain the battery, for example when a Windows update is loaded. You can often recognize the activities of the notebook by the fact that it has warmed up when you take it out of the backpack.
Unfortunately, S0 mode can often no longer simply be disabled. This is partly down to Microsoft, as the proper Windows settings have disappeared over the years, but BIOS manufacturers are also contributing to the problem by only supporting S0, even though today’s processors have different sleep modes.
Which is a possibility: Going back to S3 (Suspend to RAM) in sleep mode. This can optionally still be enabled in the BIOS. If not, it will be interesting to see if Microsoft offers a solution for Modern Standby.
You can manually set modern standby to “Network disconnected” using two commands:
- powercfg /setdcvalueindex scheme_current sub_none F15576E8-98B7-4186-B944-EAFA664402D9 0
- powercfg /setacvalueindex scheme_current sub_none F15576E8-98B7-4186-B944-EAFA664402D9 0
Go back to “Network Connected” with the same commands, just replace the “0” at the end with “1”.
