Computer wakes up from Sleep mode immediately

Hi,



Thank you for writing to Microsoft Community Forums.



I appreciate the efforts taken by you in resolving the issue. I understand that the computer wakes up immediately after putting to sleep.



However, please let us know:

• Are you aware of any canes made to the computer prior to this issue?
  
• Which build version of Windows 10 is installed on the computer? Refer
  Which version of Windows operating system am I running?
  

There could be several reasons for the computer not going to sleep mode. To determine which device is causing this, we can run a simple command and check the reason why the computer woke up from sleep mode. To do this refer the steps mentioned below:

1. Type command prompt in the search bar on the Taskbar.
2. Right click on the command prompt icon and select Run as administrator.
3. Now, paste the following command and hit Enter: powercfg lastwake.
4. Share the results of the command.

The above command should let us know the device that is preventing the computer going into sleep mode.



Please reply with the status of the issue, we will be glad to help you further.

No internet when computer wakes from sleep mode

No Internet when computer wakes from sleep mode or from cold start until I disable the Local area connection and then enable it.

When I run the diagnostic after it fixes the connection it says this: Local Area connection doesn't have a valid IP configuration - Fixed

But its not fixed. Every time I wake my computer up from sleep mode after its been in sleep mode for a few hours I have to disable and then enable the Local area connection.

When the computer wakes up it has a yellow triangle warning of limited or no internet access. So I have to do the above every time I wake it up.

Things I've done so far: Update drivers, No fix.
