I got a laptop, not too long ago, when I put the laptop to sleep, in not less than 15mins, it comes on by itself, so I tried to patch it up, and got it fixed, these methods should work for you.

Stop the mouse from waking up the PC

Mice, especially, wireless mice, can sometimes wake the PC up. In fact, there is a specific setting to allow this. If the mouse turns out to be a problem, you can change the setting with this procedure:

  1. Open the Start menu and type “mouse” (without quotes) in the Search bar
  2. Under the Control Panel list, click “Mouse” (or just press Enter in Vista)
  3. In the dialog box that opens, select the tab “Hardware”
  4. Highlight the entry for your mouse and click the button “Properties”
  5. A new dialog will open. Click the button “Change settings”
  6. In the new dialog that opens, click the tab “Power Management”
  7. Remove the check by “Allow this device to wake the computer”
  8. Click “OK” and close the dialogs.

The mouse properties dialog is the same in Windows 8.1/10. Here is one way to access the mouse settings:

  1. Right-click the Start button
  2. Select “Control Panel” from the context menu
  3. Enter “mouse” in the Control Panel search box
  4. Click “Mouse” in the list that opens
  5. The mouse dialog  box will open
  6. Proceed the same as indicated above from step 3 on

Stop a network card from waking up the PC

From what I read, a network card is the most common source of wake-up problems and that was the cause of my own computer never staying asleep. Here is how to configure a network card:

  1. Open Device Manager. There are many ways to do this but a quick way is to enter “dev” (without quotes) in the Start search bar and click “Device Manager”
  2. Expand the list for “Network adapters”
  3. Right-click the adapter to be configured and choose “Properties”. There may be several adapters, one for Ethernet, one for wireless, and others like Bluetooth
  4. In the dialog that opens, click the tab “Power Management”
  5. Remove the check by “Allow this device to wake the computer”
  6. Click “OK” and close up Device Manager

Device Manager remains the same in Windows 8.1/10. To access it:

  1. Right-click the Start button
  2. In the context menu, select “Device Manager”
  3. Proceed as given above from step 2 on

Scheduled tasks , updates, and other causes

Sometimes a task or Windows Update is scheduled for a specific time and will wake up the computer.

.

Use the command line to find what causes the PC to wake up

One way to find out what is causing a wake-up problem is provided by the command line. Open a command prompt(run as administrator) and enter this command:

    powercfg –lastwake

The last device that woke up the system will be shown.

To find out which devices are enabled to wake up the PC, enter this command

    powercfg -devicequery wake_armed

These commands are the same in Windows 7 on up through Windows 10.
