Laptop turns on automatically when I open it. How do I stop it?

@J-Money-Love  That only happens if the system is asleep, not fully shut down, but it seems to be a behavior that's part of the new "Connected Standby" systems -- so chances are you'll see that behavior more often on newer laptops.  It surprised me when I first noticed it on my wife's XPS 13 9350, and my initial reaction was that I wanted to disable it, but I suppose in the overwhelming majority of cases where a system is asleep and the user opens the lid, it's reasonable to assume that they will want to wake the system up rather than just staring at their still-asleep laptop while the lid is open.  One thing you could try if you really wanted would be to disable Connected Standby entirely, which can be accomplished with a registry change (you should be able to find the details by Googling), but even if that changes this behavior, disabling Connected Standby has a wider impact than that.

You need to change what the power button is doing right now it sleeping, you want it to shutdown the notebook https://www.tenforums.com/tutorials/69741-change-default-action-power-button-windows-10-a.html

Also check you power setting follow the path at the top of the window to get to these options.

Control Panel/All Control Panel Items/Power Options/system settings

@Clintlgm  the OP might not be using the Power button; he might simply be closing the lid.  And either way, he might want to be able to have a Power button press or a lid close action cause the system to sleep rather than shut down, but NOT have the system wake up simply by the lid being reopened.  Those are two different things.

i was able to disable this feature with the article suggested.

You should accept the reply as the answer you needed and close out the thread

The article you link to is indeed the answer. Thanks! I'm not sure why you included the bit about the diagnostics check and Dell Support Assist. It's just a setting, not a diagnostic issue. The only problem is that Dell put the lid/power option in the BIOS (whatever that is) instead of including it as an option in the Power Management section of the Control Panel.

I guess Dell thinks that turn-on-laptop-when-lid-opened is all that. However, for all the great reviews of my particular laptop (XPS13 bought in April 2020), one issue several reviewers complained of is that the lid doesn't stay as tightly closed as previous versions of the XPS13. That's not SUCH a big deal, except when the manufacturer builds in a power setting that relies on the very hardware functionality they fell short on in their updated design! 

Please tell me how did you solve that issue? Where are those settings?

Thanks
