@balveenI have a third party USB C adapter (Hyper Drive - 3xUSB 3, LAN, HDMI), and whenever connected my laptop goes to sleep only once in 5 times, and when it does it takes a long time for fans and keyboard light to turn off.
Even in cases when not having ANYTHING plugged in, the laptop often wakes up from sleep for no reason. When I check powercfg /sleepstudy it says the reason for waking up is keyboard input. But the laptop is sitting with closed lid, nothing is touching it. Something isn't right. (Btw, I checked powercfg -a, and the laptop is in "disconnected standby mode".)
The laptop simply does NOT sleep properly, and MANY people have this problem. I can't just close the lid when I'm done with work, I have to use hibernate. And then wait 20 sec for the laptop to wake up the next time.
Will you please fix this? You're behaving like an ostrich, putting your head into the sand, pretending the problem will go away with time. People feel cheated. Can you really have a clear conscience and ignore all the people who paid a lot of money for this half functional laptop?
Everything @balveen said is just wrong, and it is so cringe how no one working at Dell seem to have any true idea, what they are talking about.
1. you cant toggle or switch during Windows 10 setup, if you want connected or disconnected standby
2. you cant switch between connected and disconnected standby anymore, since over 1-2 years (not sure which major update it was), but MS changed it. There is no toggle option anymore under System->Energy (you were able to select if you want to use connected or disconnected)
3. The current setting you can chose from is this: https://i.imgur.com/jxc4Pi5.png It will disconnect WLAN during modern standby.
So everything Dell is telling here and everywhere else is total nonsense. They have no idea, what they are talking about. This is not the cause of drains or your laptops "burn to death" in your bags.
Another <attacking> post by Dell to keep the problems under the rag and hopefully the issues goes away by itself through time or should I say after the users moved on with this junk. Paid $2000 on this junk with all the premium support and decided to NEVER buy a Dell again.
Go to windows settings. Select "Power & Sleep" there will be an option of "Network connection" (When my PC is asleep and on battery power, disconnect from the network), change it to "Always".
From the factory settings it was selected "Never". And i faced the same problem of battery draining.
