Yoga 920 randomly wakes from sleep while lid is closed and on battery power.

My Yoga 920 seems to ranomly wake from sleep when the lid is closed. I'd had several occasions when travelling to find my latop completely dead when I needed it - or finding it burning up in the confines of my bag. A few times, I've been alerted to problem when I happen to hear my laptop make a notification sound. When this happens, the screen is already on when I open the lid and much of the bettery has been used. I've seen this occur both in and out of my bag. Nothing is plug into the laptop other then the dummy USB holder for the pen. I have Vantage installed and all updates have been applied.

Re: Yoga 920 randomly wakes from sleep while lid is closed and on battery power.

Hi nick-riggs,

 

Greetings.

 

You may be able to check what services and application that last woke your laptop on CMD elevated command prompt:  powercfg –lastwake. 

 

I would suggest to initially try also the steps described here disable Allow Wake Timers and unchecking options on power management for Allow this device to wake the computer under device manager.

 

You can uncheck the same advance option /properties to which ever device that cause it to wake up like network card, bluetooth, input keyboard and pointing devices etc from the findings in powercfg -lastwake.

 

Update us how it goes.

 

Regards

Re: Yoga 920 randomly wakes from sleep while lid is closed and on battery power.

This doesn't seem helpful. The output of the command is simply: 

 

Wake History Count - 1
Wake History [0]
Wake Source Count - 0

 

When I go advanced power options, the option under power concerning "wake times" isn't an option:

And of all the devices I've checked in device manager, none of them have a "Power Management" tab:

Hi nick-riggs,

 

Greetings.

 

If you try powercfg -devicequery wake_armed in the elevated CMD, this would give off the hardwares that wakes the machine when a condition like wake timers and scheduled task such antivirus scan or Windows / application update. Either disabling the hardwares like wifi via airplane mode or changing how machine wakes from sleep.

 

Other options you can try below:

 

Go to Settings> power option> change plan settings> change advance power settings> allow wake timers :disable >apply >ok

 

Control panel> Security and Maintainance> Change Maintainance Settings> uncheck Allowed Scheduled Maintainance

 

Seach for Task Scheduler and right click to properties, under Conditions Tab to uncheck Wake this computer to run this task

 

Try to observe how it goes.

 

Regards

powercfg -devicequery wake_armed returned "NONE". 

 

"Go to Settings> power option> change plan settings> change advance power settings> allow wake timers :disable >apply >ok"

 

Best I can tell, Windows 10 doesn't have doesn't have options for "wake timers" anymore. At least not where you are suggesting. 

 

"Control panel> Security and Maintainance> Change Maintainance Settings> uncheck Allowed Scheduled Maintainance"

 

Again, this doesn't seem to be an option in Windows 10: https://imgur.com/a/XuR11

Hi nick-riggs

 

Greetings.

 

Would it wake up with the internet access disconnected ?

Would you have this issue eversince you have the machine?

 

I would suggest that you try to call in technical support so that they would be able to remotely check the system if there is anything that triggers wake cycle or if disabling hybrid sleep and shutdown as an option.

 

Regards

Re: Yoga 920 randomly wakes from sleep while lid is closed and on battery power.

This is still happening. Today leaving for the airport I closed the lid and packed the laptop. The laptop was at 100% power. After getting through security, I heard the laptop make a sound... ugh... I got it out and it was very hot to the touch. It once again, it didn't sleep when the lid was closed. And was now at 45% power - so much for working through today's travel.

 

It's clear after all the steps, this is a defect. How do I go about returning this heater?

Hi nick-riggs,

 

Greetings.

 

You can check the options for repair as I am not sure at the moment if returns are possible without having the machine serviced yet as implied by the warranty aggreement. The best way to proceed is to call in technical support.

Try this: Settings -> Power and Sleep -> When my PC is asleep and on battery power, disconnect from the network -> Always.

 

I'm not sure if this helps in your case, but it won't hurt to try.
