Modern laptops have something called "modern standby" (S0 mode)
It means the laptop stays active during sleep. This S0 mode is non compatible with openVPN tap-driver or Wintun driver. After windows suspend, it can take up to 2 minutes before openVPN is reconnected which is quite annoying for users.

seems openVPN was looking into S0 in respect to DCO: OpenVPN/ovpn-dco-win#64

for Tap driver or Wintun there is no fix yet.

Some laptops can be forced with a registry setting from S0 mode into S3 mode, however latest laptops don't support in BIOS S3 anymore. reference: https://www.reddit.com/r/Dell/comments/h0r56s/getting_back_s3_sleep_and_disabling_modern/

We need to investigate a workaround/fix for our Wintun implementation.
