This happens randomly. I can't seem to reproduce it on call. Basically I close the lid to put it to sleep but the computer doesn't go to sleep. Airplane mode just turns on but the laptop stays on.
Thanks for writing to us.
When did the issue start?
Please update the BIOS and video drivers, also check the advanced power option settings ensure nothing is hindering the sleep mode from working.
Also do let us know what windows the system is running on, do PM us the system tag# by clicking on my name in blue and select send a private message .
Meanwhile you can go through the below steps to check more on the issue
Open the Start menu and then enter cmd into the search box. Hit enter and the command prompt window should open for you. If not, click it in the search result list.
Note: it is possible that you will need administrative privileges to complete the next part successfully. If you are having trouble, you can attempt to run cmd as Administrator. To do this, search for cmd again, and then right-click it and select Run as administrator.
Now that you have the command prompt window open, enter the following at the command prompt:
There is a space after powercfg
Hit enter .
If any process or device is preventing your system from going into sleep mode, information about it will be displayed here. The program will attempt to give you precise information on the disturbance
Though we can always rely on this method, but good to give it a try.
For sure one of the programs is stopping the system from sleep which is hard to find out.
Let us know how it goes.
Hi nice to hear from you.
The last we can think of is to reinstall the windows afresh, but before proceeding with that, please let us know if the issue was there from day one or if it started lately.
If it started recently then please try a system restore or if you remember changing/updating any software , could be windows update as well, uninstall them.
Post the restore if still the same, windows installation afresh is what we can do next.
We have seen many windows 10 users facing sleep related issues most of which are due to software .
