Fix computer auto-start

If your Windows computer restarts on its own after being put into Sleep mode or randomly restarts on its own, the culprit is most likely due to hardware or software problems. The next part below Taimienphi.vn will show you some ways to fix the error that the computer automatically restarts after shutdown or put into Sleep mode .

Method 1: Disable, turn off Fast Startup

Windows 10 is integrated with Fast Startup mode, this mode does not turn off the computer in the usual way but keeps the computer in a mixed state so that when the user reopens the computer the process will happen faster. However, this can also be the cause of the error that causes the computer to start automatically when plugged in, so the solution is to disable, turn off Fast Startup.

If you don't know how to disable and turn off Fast Startup, readers should refer to the article Quit Fast Startup , fix black screen error when starting win 8 and win 10 on Taimienphi.vn to know how to do it.

Method 2: Prevent Task Scheduler from waking up the computer

Sometimes the culprit causing the error that causes the computer to start up automatically after shutting down, the computer restarting itself many times is more software than hardware. Chances are you are using Scheduled Task to track and complete some of your tasks at specific times of the day. In this case, the way to fix the computer restarting error is to change the Power settings to make sure the device skips tasks when in Standby or Hybrid mode.

Step 1 : Open Power Options => click Change Plan Settings .
Step 2: Make sure you have selected the correct Power plan , then select the Change advanced Power settings option.
Step 3: Find and expand the Sleep section to find the Allow Wake Timers option and disable this option.

Do the above to ensure that no program can wake up the computer even when the device is in sleep mode or when it is turned off.

Note: This method only applies to laptops.

Method 3: Disable, turn off Automatic Restart (automatically restart)

If the computer crashes many times and the system restarts on its own, the cause may be the Automatic Restart feature. The solution to fix the error in this case is to turn off Automatic Restart to fix the error that the computer restarts continuously without showing the screen.

Method 4: Mouse or keyboard wake up the computer

Besides, the mouse or keyboard can also be the culprit causing the computer to restart itself continuously, sometimes just lightly touching the key or mouse can also start the computer when it is in sleep mode, . .

These devices include a power management option, which we can disable to ensure these accessories do not wake up the computer, unless we really want to.

Open Device Manager by pressing Windows + X then pressing the M key. This window displays a list of all computer hardware. Here you choose mouse or keyboard.

In addition to the mouse and keys, if you are using other gaming devices to play games on your computer, you will have to disable or turn off the power options for these devices.

To find the devices that are the cause of waking up, causing the computer to restart automatically, we use the command powercfg -lastwake that Taimienphi.vn introduced above. Try disabling each device to find out which is causing the error.

Note : Make sure at least, either the keyboard or the mouse has the ability to wake the computer if you don't want to have to press the Power button every time you wake up, turn on the computer from different sleep modes.

Method 5: Turn off the Wake On LAN feature

If the computer is connected to the network, Wake On Lan can bring the computer back online. This feature is extremely useful if a computer wants to communicate or send data and files to another computer on the same network that only comes online when requested.

Wake On Lan built into the hardware, ie the network card, can also be the cause of waking up the computer and causing an error that causes the computer to start up on its own. To fix the computer booting error, we will turn off the Wake On Lan feature.

Open Device Manager by pressing Windows + X then M key. In the Network Adapters section , find any network, the default is Miniport.

Right-click it and select Properties => Power management => Uncheck the option Allow this device to wake up the computer .

In addition, Windows also has a built-in Automatic Maintenance mode to wake up the computer at the set time and update all available updates on the computer.
