Yoga 900 does not sleep

Q: Yoga 900 does not sleep

When I close my Yogo 900, it often does go to sleep. It continues to run (and of course eating battery). I've installed all the latest drivers and BIOS. Any ideas how to solve this?

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

Hello, we got 2x Try-and-Buy Lenovo Yoga Tablet Laptops (an X1 Yoga and a Yoga 260) to evaluate their suitability for our company, since we intend to upgrade several of our employees laptops. However, ever since we got the devices we noticed on both of them frequent issues with the display and waking from sleep. Very often the laptops won't wake up properly with the screen staying black. In those cases the display-backlight seems to turn on, and I assume the system is running somehow in the background. Putting the computer to sleep again (e.g. by closing the lid) makes the computer wake up properly on the second attempt. Different error in the same category is when a video is running and the laptop is connected to AC - plugging out the AC cord made the screen go black while the media content's sound kept playing. All drivers were updated to the newest version via Lenovo System Update 5.07.0029. Any ideas? I also tried to open a support ticket, but Lenovo wanted to send and install a new display (!). Apparently, that seems like a driver/software issue?! Best regards

In the past 2 days, my new Yoga 14 has gone to sleep while in use. If I check the event log, the sleep reason is button or lid. I've got about 2 weeks left on the return window and will probably return if I can't find a solution for this.

I've had the problem where the Yoga 3 won't turn back on.   Fully charged, power cable in and out, even tried the hold down the power button for 10, 20, 30 and 60 seconds. Disconnected the battery, ran off power cord and ran every virus/system check.  Put everything back together and everything works fine.... for a day or so, then same problem. Thoughts? Is this a function of coming back from sleep, i.e. can I work around this by never letting it go to sleep?  Would replacing the battery fix the issue (and if so which battery should I get?) Sean

I have a Yoga X1 (1st generation).  I have the screen set to max brightness.  When I wake the laptop from sleep, the screen is always dim for a few seconds before going to 100% brightness.  I would like the screen to start at 100% brightness.  How do I prevent it from starting dim.  (Note: I have adaptive brightness turned off and I tried going into the Intel Graphics Settings and changing the Power Plan to Maximum Performance.  These interventions didn't solve the problem.)

Hi all, I've had a Yoga 13 for nearly a full year now with no problems until recently, when the laptop has constantly failed to enter sleep mode when the lid is closed. As a result, the laptop will continue to run in my bag until the battery drained. It is not a problem of rewaking when closed, as the screen will remain on with lid closure and the laptop never enters sleep mode. Is there a way to tell if this is being caused by a software problem (recent update to 8.1) or if the hardware involved in sensing a closed lid is now faulty? Steps already taken:Usng advice from a previous thread, I have uninstalled the Lenovo Energy Management software - this does not solve any conflicts with Window's own energy management.Power options shows that device is supposed to sleep on lid closure - changing settings to hibernate did not cause machine to hibernate on lid closure either.Powercfg shows no wake timers, -devicequery wake_armed shows "RTL8723A 4.0 + High Speed Chip." However, these should only be impacting the problem if it was waking from sleep - my device never enters sleep in the first place. Thanks for the help - hopefully I can fix this while hanging on to this fantastic laptop.

A:Yoga 13 does not sleep on lid closure

I know I'm digging up an old post and I'm not sure if you've figured it out. I also had this problem and I think I've 'fixed' it. When I was trying to diagnose the problem, I too tried to watch the screen closely as I closed the lid. I noticed that right before the magnets click together, I saw a notification appear on the screen. If you open the lid again fast enough, you might be able to see the message. The message I saw was a digalog box asking me if I wanted to enable tablet mode. This made me think that for some reason, the laptop thought I was actually folding the screen backwards (into tablet mode) when I was actually closing the lid. What I did was to fold the screen all the way back, waited for the computer to show the dialog box, I chose an answer (I think I chose 'Always ask'), and then folded it back into regular laptop mode. I closed the lid, the screen turned off, and the computer went into sleep mode (the setting I chose in Power Options). Hope this helps.

Just got a brand new Yoga 710 w/ Win 10 Pro and the system just shuts down when put to sleep.Happens when:- I close the lid (even if "close lid" power option is set to sleep), or- I select the "Sleep" option from the Start [equivalent] menu, the system immediately shuts down (within seconds),- Leave the system idle for 5 min (what sleep timeout is set) And since it shuts down:- I lose any open document, applications running, etc. Also, on restart, Windows occasionally will also complain that it wasn't shutdown properly, starts to scan disk, etc. This is really BAD!- Pressing the mouse or keyboard doesn't do anything and only pressing the power button will get it working again (and I see the Lenovo BIOS logo, etc.).It feels like the OS is trying to go to sleep, but the laptop is shutting down instead. I tried calling Lenovo customer service but the response was really really unacceptable:- First tried to disable sleep completely and saying that that since this is a new machine so that should be okay.- I asked what about battery life if I don't use the laptop (say overnight) for a while -- response was I should shutdown the laptop. I checked the power option, tried disabling hibernate, disable fast boot, etc. and other suggestions from searching the forum but nothing worked.   Also checked BIOS settings but there's not much that can be changed (which is rather surprising).Drivers are BIOS are up-to-date. Any other ideas?  Any one else seeing this i...

Anyone else having a problem with it not waking up from sleep? I put it to sleep, the screen goes black and the keyboard is still lit up.

Hi everyone,  I bought a Yoga 920 about a month ago, and in the last week or so have had an issue with the computer's sleep function. Essentially, when I put the computer to sleep (either by shutting the lid or clicking using the mouse or pressing the power button), after a few minutes, it will not wake like you would expect it to do so under regular operation. The only way to awaken the laptop is to hold the power button and do a hard reset. This has caused me to have to do a hard reset multiple times a day.  The issue appears to be similar to this: https://forums.lenovo.com/t5/forums/v3_1/forumtopicpage/board-id/ll06_en/thread-id/34896  Has anyone had a similar problem? What solutions are there?

I had posted about this near the start of 2016 and then a BIOS update was released to fix the issue. The Yoga 900 wakes up from sleep when picked up and rotated. Previously, the issue was with the screen hitting the buttons and waking the laptop up. Now, I think it might have to do with rotating it when it is asleep. I do not have this problem if I rotate the laptop as it is going to sleep, only if I pick it up after it has gone to sleep. I have been having this issue since the last BIOS update was released. Is there some way to fix this problem? If not, can an update be released to fix the issue? If I need to clarify something about the problem, please let me know.

I cannot get the Y2P to shutdown or sleep. When I try to shut down it powers off but after about 2 seconds it turns itself back on and boots up. Same thing happens when I try to sleep. Please help! I've tried pretty much everything I could find online including the following: Turn off wake on lan on the network adapterTurn off auto restart on windows errorsUpdated biosUpdated driversDisabled all non microsoft servicesFactory reset of the OSWent through every device in device manager and turned off "Allow this device to wake the computer"powercfg /lastwake (shows nothing) Anyone have any other suggestions on fixing this problem? Shutting down isn't a huge deal as holding down the power button will eventually turn it off. But not being able to sleep the laptop when I close the lid is a deal breaker as the battery constantly drains.

I just spent the last 30 minutes searching for this issue and can't seem to find anyone else who is having this problem.  The issue I'm having is that whenever I flip the lid to go into tablet mode, the machine seems to go into sleep or hibernate.  It doesn't do it 100% of the time, but it will always do it when I really need to go into OneNote to take some quick notes but instead waste time having to flip it around again, log in, and flip back into tablet mode a second time.  Occasionally, it will shut down completely instead of going to sleep, or resume but with a blank screen, forcing me to manually power it off by holding the power button, but these occurances aren't nearly as frequent as it going into sleep.  Another thing I noted is that when it resumes from the sleep mode it goes into, sometimes the Lenovo Battery Guage will show up with a red X, as though a battery isn't detected.  I find it odd because the machine functions just fine on battery.  If I plug in the AC power in this state, it will recognize the AC power as plugged in, but the battery gauge's status of "no battery" does not change.  If I open the battery app, it properly detects the battery and its charge level.   Things I have done to attempt resolution:* Disable all sleep/hibernate mode options in Windows Power Manager* Checked all applicable settings in the Lenovo Settings app* Ensure system was up to date with all Windows Updates, as well as...

A:X1 Yoga going to sleep after flipping lid

I guess I've come up with a diagnosis and a partial solution.   The problem apparently was the computer constantly failing to see the battery installed.  It would randomly detect the battery as not being installed, even when I was on battery and the machine stayed on just fine.  The battery has been functioning perfectly in the sense that I could operate off of AC power without issue, but the Power Gauge would show no battery being detected, then eventually it would come back and be fine, showing the proper charge level.   The reason the machine kept "turning off", or in this case Hibernating, was because Windows is set to either go to Sleep or Hiberate when it reaches the "Critical battery action" percentage in the Power Manager.  Because the battery would no longer be detected, the "Critical battery action" would kick in because it would think the battery is completely out of juice.  Unfortunately, Windows does not allow you to set this action to "Do nothing", offering only the options of "Sleep" or "Hibernate".   The partial solution:I followed a procedure I found for another model.  It involved the following steps: 1) Go into the BIOS2) Disable the battery3) Shut down machine and disconnect the battery4) Plug in AC power and boot into the OS5) Shut down the machine, disconnect AC, and press the power button 10 times6) Reconnect the battery and AC and boot into Windows So far, after doing that proce...

Despite all my tryings, I get no sound from the speakers... So I hope I will be able to reboot it and find a suitable solution (BIOS, driver update ?).The Yoga is new (one week old) and I'm yet already struggling to bring it back to life !!!!! Question :Is there any way to manually shut down the computer (the power switch for 60 sec doesn't work, the battery can't be taken out, no reset pin hole...) ? LENOVO, please HELP !!!!!I was so happy of this computer, don't let yous customer down. PS : As soon as the battery turns off, I'll try to save the PC and let you know how it goes.Sadly, I'm already considering to turn it back.

Hi there, I'm not sure if this topic's been brought up since I couldn't find it. But I recently purchased the Yoga 920, and everything works fine except that the laptop goes to sleep after some time on it's own. I've changed the power settings for both screen lid down as well as the "put computer to sleep" to "nothing" and "never" respectively and it still happens. Even in my advanced power settings, there's only a very limited power menu. Also possibly related, there's only a "balanced" power plan, no battery saver or high performance. Regardless, it's driving me insane and any help would be appreciated, thanks!

My 14" Yoga (non-pro) seems to jump out of sleep mode whenever I put it into sleep mode. This even happens when the Yoga has been folded up and put in by bag, giving a high chance of damaging the laptop or even causing other kinds of damage. Currently I'm working around it by putting it into Hibernate (which, I admit, is also pretty fast). But that's obviously not a nice workaround. Does anybody know how to fix this? I tried to find out what causes the event but the system logs are rather strange: I do get: The system has returned from a low power state.Sleep Time: ?2016?-?07?-?23T21:07:12.012475900ZWake Time: ?2016?-?07?-?23T21:07:21.793067400ZWake Source: Power Button But I certainly haven't touched the power button, and it seem to be working fine otherwise.

I want to demonstrate aproblem I have had with my Yoga 900 to see if others have had similar issues. I discovered this when I put my Yoga, (which was asleep) in my backpack, and then later noticed it was awake. It took me a while to figure out what was happening, but I finally determined that it had nothing to do with the backpack. My Yoga 900 would wake up when picked up by the short edge (as I did to put it n my backpack). You can see this in the video:Yoga 900 Waking when pickedup (BTW -- I am not squeezing the laptop, I am just holding it as needed to pick it up by the edge. This does press down on the lid and there is upward pressure on the bottom. It is the pressure on the cover that seems to be the cause of the laptop waking) Note that Lenovo has been great, and is sending me a replacement laptop. But I am curious if others see this same problem. Is this a common Yoga 900 Issue?

I have a yoga 900 and have set the power options to make the laptop sleep when the lid is closed. When I close the lid the laptop/tablet thinks that its been switched into tablet mode and prompts you to change to tablet mode in windows. Its as if I flipped the screen all the way around the other way. The unit does not sleep and just sits there eating up battery. Has anyone else encountered this?
 
Thanks,
Landon.

You seem to be saying that you yourself have "set the power options to make the laptop sleep when the lid is closed". If this is so, I don't understand, because the Yoga 900 should be set this way in the factory by default.
 
This screenshot shows what the settings should be by default:

The Yoga 900s refuses to come back from sleep in 90% of the time. The power led is on but the screen stays black. I have to force shutdown and start the Yoga. After a couple of time doing this Windows will end up in KERNEL_SECURITY_CHECK_FAILURE and than no longer boots. After doing a reset Windows works again for about 3 months and than the whole thing starts over. Latest drivers are installed .

Hi everybody. This is just a public service message regarding an issue I've encountered. I've found that my Yoga 900 does not "wake up" after it has gone to sleep while connected to an external monitor. I'm connected to an HP 27VX monitor through a USB Type C to HDMI adapter. I found that my Yoga wakes up without issue if the display has turned off (power options turn off display settings) but it doesn't wake up if it goes to sleep when connected to the monitor. The issue though is not that it doesn't wake up, the issue is that for some reason when connected to the monitor it never truly goes to sleep (slow blinking white light). I think it gets hung up somehow when trying to go to sleep. When it enters this mode the power light is solid white and the only fix is to power cycle the Yoga. I'm not sure why it won't successfully go to sleep when connected to a monitor but my guess is some type of driver/hardware issue between the USB type C, HDMI adapter, and the monitor. I've verified that all works as intened when I'm not connected to the monitor. My workaround is to go to power options and turn my sleep option (when plugged in) to "Never". Not a solution by any means, just a workaround until all players involved (Lenovo, HP) figure out how to work with the new USB Type C port. Hope this helps. Rob

I worked with Lenovo support and the issue was resolved after we updated the Intel HD Graphics 520 Display Adapter driver

Question says it all for the most part.  Just got my Yoga 260.  Works great expect it will NEVER wake from sleep.  this is a huge problem obviously as I have to do a hard reboot by holding hte power button in until it dies then press again to boot the machine. power light blinks just as it should in sleep but nothing will allow it to wake except holding power button down doing a hard shutdown then reboot.  Anyone have a fix for this?  Thanks.
