When Vantage checks for updates, it downloads and runs several small EXEs (we call them detection EXEs) that are used to check firmware versions so that Vantage knows whether there is an available update for your system. One of these detection EXEs wrongly disabled USB selective suspend. We fixed the detection EXE as soon as we realized what was happening but then we still needed to fix the PCs that were impacted. That's what the new patch is for.

There are long threads about this topic and I reviewed them but I could not find a solution.
I purchased an X1 yoga recently and I am experiencing battery drain during sleep, on modern standby periods.
I ran a sleep study and according to the report, Nvme controller is active for most of the sleep period, there is also an unregistered device, which is also active during that time period.
I reviewed potential solutions, I updated all windows and nvme drivers from intel but it still drains 1% battery/hour during sleep.
I don't know what else I can do. Any suggestions?

Hi MatthewZhao, and welcome to the Lenovo User Community!
Just checkin' that you are aware that there are two ways to "shut down" when heading out of the office. Clicking on Shut down puts the machine into Modern Standby, which has some benefits such as fast startup, with battery drain trade offs. Shift-click on Shut down and the machine shuts down completely. Startup then takes longer, but no battery drain. I have an X1 Carbon 6th Gen and I like Modern Standby because it suits the way I work (I move around a lot) and this is how I use it.
Hope this helps!

I've had my X1 Yoga 3rd Gen for a couple weeks now, and the battery drain during sleep has been maddening. I've found the sleep behavior to be unpredictable. Sometimes it'll sleep without much battery drain, and other times some process will be active the entire time and waste the battery. I never know what I'm going to get in the morning when I wake up my computer. Will it have gone into hibernation mode? Will it not revive at all? Will half of the battery be drained?
Just yesterday evening I charged the computer to 100%. It is now at 14%, and I've only used it for under 2 hours. The rest of the time it's been sleeping. I can't believe I spent $1700 on a computer that has the equivalent battery life of the 7-year-old MacBook Pro it's supposed to replace. I've adjusted all the setting I could find to reduce this problem, but I'm just not willing to spend all my time diagnosing the battery problems of an expensive new laptop.
Fortunately, Lenovo has authorized a return. I'll be sending this back.

Shame on Lenovo. No S3 support, no WWAN support on Linux, no fingerprint reader support on Linux...
This was my last buy from them. Will never recommend this brand again.

Modern standby is an absolutely untenable situation also in my case: Programs will randomly crash or close, battery drain is totally unpredictable and the fan/heat during modern standby is really just a loose cannon and makes you worried about whether it will run hot as a plutonium rod in your bag.
I also demand S3 sleep!
