Modern Standby
Not my favorite topic. It’s not how I want my ThinkPads to act, but it seems here to stay, and perhaps the general laptop audience actually welcomes it…
Modern Standby is a sleep mode that keeps one eye open. The laptop can still access the network (subject to a bit of user control) and get background things done when “asleep”. Lenovo’s implementation/enhancement is Smart Standby.
Some configuration is possible via Lenovo Vantage, and there’s a BIOS option (in the fancy GUI, self-healing BIOS) to switch completely over to the old S3 sleep mode. This has been a relief to Linux users (Linux doesn’t support Modern s0i3 sleep… yet) but Microsoft says that if it’s toggled Windows must be reloaded. I’m not entirely sure that’s true – but fair warning.
I’ll admit I haven’t fully come to grips with this new “feature” and will try to learn more and update as possible. I have discovered that enabling Smart Standby overrides my chosen hibernation timing 🙁 Smart Standby was enabled by default along with a 6AM resume/wake up. Not nice. That’s not something that should happen without user interaction IMNSHO.
