Computer with windows 8.1 is unexpectedly waken up from sleep and is shut down after hibernation
My computer is Lenovo yoga 13 with 8G memory. It originally ran win8.
After updated to win 8.1, it still works perfectly but with two problems.
First, when the computer goes into sleep mode, usually when I close the lid, it will occasionally wake up in
my bag and then run on into hibernation until the battery is dead. In hibernation mode, about 50% chances that the computer will end up in shut down mode when I tried to wake it up.
This is quite annoying since some of my programs does not have the auto-save
function, and this unexpected shut down causes the loss of work progress.
Does anyone have ideas? Thanks!
Keys to the Problem Computer with windows 8.1 is unexpectedly waken up from sleep and is shut down after hibernation
This issue might occur if there is device that is triggering Windows to boot from sleep mode.
Sometimes, scheduled automatic maintenance could also cause Windows to automatically wake Windows from sleep or hibernate mode.
Outdated/incompatible display driver
might also cause such issues.
I would suggest you to use Command Prompt (admin) and then find out the device or the automatic maintenance that is causing the issue.
Follow the methods:
Follow the steps below to run the command in Command Prompt:
Type “cmd” on the Start screen.
Right Click on Command Prompt and select Run as administrator.
Type the following command and hit Enter:“powercfg –lastwake”
Take a note of the device name or the task details that is causing the issue.
You can also use these command for troubleshooting the issue:
Type cmd on the Start screen and right click on it.
Run as administrator.Type the following command and hit Enter:
Powercfg -devicequery wake_armed
You will get the name/names of the devices.
To disable a specific device from waking the computer, run the following command:
Powercfg -devicedisablewake "devicename"
Note: Make sure that you replace the “devicename” placeholder with the name of the device that you want to disable.
If this issue still occurs after you disable one device, disable the devices in this list one by one until you determine which device is causing the issue.
If you want to re-enable a device to wake the computer, run the following command:
Powercfg -deviceenablewake "devicename"
Let us know the results of these commands in Command Prompt if the issue still occurs and proceed to the next method.
You can follow the steps to run the power troubleshooter on the computer
Type troubleshooting on the Start screen.
