Win 10 - computer won't lock or sleep when lid is closed

Hi Shari, 

Thank you for posting on Microsoft Communities.

Please follow the methods mentioned below:

Method 1: Follow the steps:

1. Press Windows Key + X.

2. Select on Control Panel.

3. Click on Power Options.  On the left, click on "Choose what closing the lid does".  Click on the drop down menu for "When I close the lid" and choose "Sleep" or "Hibernate.

Method 2: I suggest you to run in-built Power troubleshooter and check. Follow the steps:

1. Press Windows Key + X.
2. Click on Control Panel.
3. Select Troubleshooting on the left pane, click on View All.
4. Click on Power to run the troubleshooter.

Method 3: If the above method doesn’t help, I would suggest you to reset and restore all of the default Power Plans back with their default settings. Follow the steps. 

1. Press Windows Key + X.
2. Select Command Prompt (Admin).
3. At the command prompt, type powercfg -restoredefaultschemes, and then press ENTER.
4. At the command prompt, type exit to exit the Command Prompt window.
5. Restart the computer and check with the issue.

Let us know if the issue is resolved or if you require further assistance.

Thanks for the help. Even tho with win 10 my computer no longer locks unless I do it manually, I have followed your instructions to put it to sleep.  

    With win 8, it would lock and sleep with my lid closed or after a time limit whether I had programs running or not.  With win 10 NO programs can be running for the lid close to sleep.  And with win 10 I can expect my computer not to lock unless I manually do.  Bad feature. 

   Thanks for your help

its simple with the password lock when you close your lid:

go into settings

click on account

and click on SIGN IN WHEN

it should say when windows gets woken up what does it do

the drop down feature should allow you to lock it again

I've noticed this frustrating problem along with a couple of other rather major/bizarre flaws in the new Windows 10. How i fixed this was as follows:

I imagine most people have done this bit but here goes anyway: 

Settings -> Accounts -> Sign in options -> Require sign in box (at the top) and select ' WHEN PC WAKES FROM SLEEP'.

THEN i did the following:

Settings -> Personalisation -> select screen saver settings (at the bottom) -> Select the screen saver you want or select none BUT MAKE SURE you check the box that says 'ON RESUME, DISPLAY LOG IN SCREEN'.

Hope that works for you all...

Having the same problem I tried many proposed solutions without any success.

It's really weird that the computer restart randomly without any apparent reasons.

One possible cause of this problem could be a Bluetooth mouse (that switches off automatically) connected to the laptop.

Both the wireless mouse and the laptop are most probably carried together in a bag. Any click of the mouse performed by any pressure in the bag will wake the mouse up and send a signal to the laptop which may in its turn wake up from sleep mode.

Does it make sense?
