Yoga 900 - does not display on external monitor when awaking from sleep / energy save

Q: Yoga 900 - does not display on external monitor when awaking from sleep / energy save

Hi, I'm using my Yoga 900 on the desktop for longer periods of time. When it awakes from sleep it does not always "remember" that it was last displaying on the external monitor. Sometimes I have no picture at all, sometimes I have the picture on the internal monitor. When I switch to external only with F10, it won't do that, so the external monitor (HP 24es) won't wake up. Up to now my only solution is to plug out and back in the Type C adapter (Apple 3x multi adapter). That's definitely not what I want to do several times a day. Thanks for any hint...!

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

I routinely use a second monitor but these last few weeks either the laptop doesn't recognize the 2nd monitor or else it does breifly and then the monitor blanks and goes into low power/power saving mode.  Same issue with two different monitors.  There is no problem with the laptop's built-in display. After researching, I suspect it is a by-product of the recent Windows 10 update.  Mixed advice on solutions.  I tried updating all my drivers from Windows Device Manager.Several posts recommended going to manufacturer (intel) and downloading drivers. Its automatic utility did not detect a current driver, but under older versions there was one from about a year ago. (I didn't try to install.)I've changed power settings so have monitor "always on". No difference. What else can I try? This is really frustrating.

Hello all,

I've set my external monitor as primary because the laptop screen is broken, via Q&A: How do I make an external monitor my laptop's primary display?.

However, when waking from Sleep the primary display is switched to the broken laptop screen instead of the external. If I hit Window+P on my external wireless keyboard, I am able to select the external monitor and then it will come on, most of the time.

Is there a way to set the external monitor as the primary after sleeping? Perhaps a third-party program or registry tweak? I've googled around and searched this forum, but have not had much luck. All drivers are up-to-date

I found this forum post which looks promising, but not sure if the solution proposed is applicable to my case.

Thank you.

For a couple of years I've my Yoga 900 laptop with 2(!) Dell P2415Q 4K monitors using a USB-C to MiniDP dongle. I was shocked the laptop could handle both of these monitors (combined resolution 7680x2160!), but it did just fine. I recently sold them and am now using the laptop with a single Dell U3417W widescreen monitor (resolution 3440x1440). For some reason, even though the new monitor has FAR fewer pixels that the two 4K monitors did combined, the laptop will now frequently get into a state (often after a sleep/wake cycle) where the screen starts blanking out every 3-5 seconds. Usually I can't get it to stop until I do a shutdown and cold restart of the laptop. I have the latest display driver available on Lenovo.com for this laptop. What's going on here, and how can I fix it? Thanks in advance for any help!

I run 3ds max and photoshop on my computer. I have an Nvidea 7300 GS graphics card and a Dell 2007 WFP 20". For two months now I've been trying to diagnose why my monitor keeps going into energy save mode. The monitor has both VGA and DVI. It started with the DVI plug and the computer would need a restart to get it back on. So I switched to VGA and that worked for a little while and then it started happening again. I then opened up the computer , took out graphics card cleaned it and fastened it back into its slot...no improvement. I set it to the lowest refresh rate, still nothing. I did a video card stability stress test and the results turned out fine.

I switched my monitor with my other dell 17" monitor to test if it was the monitor, which only has a VGA plug and it never turned off...it worked fine. And the 20" Dell did fine on the other computer as well. I could continue working with the monitors switched but I would like to do my 3D work on the bigger screen with the DVI connection (since thats what I bought it for)

Unfortunately, I don't have another video card to test it out but I"m at my wits end. Is it the graphics card? Is it the cable port on the graphics card? Is it both the DVI and VGA cable itself? Is it the motherboard? Is it the temperature? WOuld changing my NVIDEA settings help? Do my BIOS need to be changed? Any advice or suggestions would be greatly appreciated!

A:Monitor keeps going into energy save mode

Have you checked your bios settings and made sure the bios isn't causing the problem.
Disable the power settings inside the bios. Check to make sure your power settings in the OS itself aren't set to turn off at 5 minutes and change them. Jazz

When I boot up without a connection to an external monitor I experience some display issues with text sizing of certain objects within certain applications (e.g. Microsoft Visual Studio).  In these applications parts of the User Interface display perfectly.   Other parts of the same application will have vastly oversized objects and text.  And, in another application the text is greatly undersized in certain portions of this app. When I boot up while connected to an external monitor everything displays perfectly on the external monitor.   This happens without making any changes whatsoever to system display setting or application configuration settings.  If I disconnect the external monitor the X1's internal monitor still displays everything perfectly.   But if restart while disconnected from an external monitor I experience the same display issues as described in the 1st paragraph. I don't think this problem was always there, but  I cannot say for sure.  It just got so annoying that I finally decided to write to the forum today.   I would guess that the problem has been this way for 1-2 months. The Lenovo System Update app tells me that everything is up to date.    Is there some setting or perhaps driver that needs to change? Tim

Lets enable the MiniDump Click Start, point to Settings, and then click Control Panel.
Double-click System.
Click the Advanced tab, and then click Settings under Startup and Recovery.
In the Write debugging information list, click Small memory dump (64k).

To change the folder location for the small memory dump files, type a new path in the Dump File box

Hi guys,

I'm kindly asking for some help around the above-mentioned issue. This is happening on an old Toshiba laptop (model: A200-1M8). The install is basically fresh, since it was done about a month ago. Or two. Everything is working smoothly. Except when I want to give the machine a bit of rest.

When I put it to sleep, everything goes as it's supposed to. But after awaking it with the power button, the locked screen appears for a few seconds, and then the BSoD shows up. The error code is:
0x00008086 (0x00000101, 0x00000338, 0x0000001B, 0x00000000)

When I put it to hibernate, the error code is a bit different:
0x0000007E (0xC0000005, 0x88F7EFC5, 0x8B357C24, 0x8B357800)
iaNvStor.sys - Address 88F7EFC5 base at 88F7B000, DateStamp 4a4c052e

Now I've done a ton of reading about this, but found no real answer. I know the .sys file points to a driver from Intel, so I went and installed the Robson Package, which has the Intel Storage and Turbo Memory driver. The funny thing is, it worked normally the first time after the install, but that was it. The next time it happened again.

Any ideas? I've spent the better part of the day trying to solve this.

A:Blue Screen after awaking pc from sleep mode

The bottom line seems to be this:

Probably caused by : nvlddmkm.sys ( nvlddmkm+12b10 )

That's your Nvidia display drivers.

Nothing to suggest but try updating, reinstalling or a different version.

If you are overclocking, reset to defaults and take pains to ensure you are not overheating.

There may be a problem with the card itself.

If you are using a "SLI" configuration, try disabling that for test purposes if necessary.

A:BSOD I think, laptop restart after awaking from sleep

BSOD's blame your Atheros wirelss network device. Please:
- download a fresh copy of the latest, Win8 compatible version of this driver
- un-install the current version from your system
- install the freshly downloaded copy
- monitor for further BSOD's

Daemon Tools (and Alcohol % software) are known to cause BSOD's on some Win7 systems (mostly due to the sptd.sys driver, although I have seen dtsoftbus01.sys blamed on several occasions). I suspect the same issues with Win8 also.

Please un-install the program, then use the following free tool to ensure that the troublesome sptd.sys driver is removed from your system (pick the 32 or 64 bit system depending on your system's configuration): [S] DuplexSecure - FAQ [/S] Link broken as of 21 Jul 2012

Please update these older drivers. Links are included to assist in looking up the source of the drivers. If unable to find an update, please remove (un-install) the program responsible for that driver. DO NOT manually delete/rename the driver as it may make the system unbootable! :

Having this issue with Windows and in Radeon Catalyst, in power options for monitor sleep settings this will not save if I set it to never. So invariably it turns off monitor after 15 mins, in movies and playing music this turns off sound. Really annoying it started doing this awhile back and seems no way to save the setting. Always defaults to turn off monitor after 15 mins. I have it set both in windows and catalyst to never but never saves (on a restart).

Well usually I don't get these after awakening from sleep mode; maybe only a few times in the 8 months I've been using my computer.

This morning, after waking my computer from sleep in the morning (it was probably in sleep mode for about 8-9 hours), I got a BSOD.

I let everything run its course, however when my computer booted back up I realized that I had no internet connection. I turned off my router, waited a bit, started it back up, and then I was able to connect again.

However, I had to go out, and let my computer go back to sleep. Alas, once again when I woke it up my internet was gone. A reboot/reset of router/modem was required for the internet connection.

Later, I had to go eat dinner, and of course let my computer go back into sleep mode. Once again when I woke my computer from sleep mode, my internet connection was gone.

TL;DR BSOD after sleep mode one morning, now every time my computer comes out of sleep mode, I have no internet.

I am connected to the internet via a local area connection from an ethernet cable. (Desktop PC).

Do you have System Restore point that predates these problems? Make sure to show dates more than 5 days old when checking.

I can run a debugging utility on the dump files if you do this:

1 > create a new folder on the desktop and call it "dumpcheck" or whatever you like
2 > navigate to c:\windows\minidump and copy the last few minidump files to that folder. *this assumes 'c' is your boot drive, if it is not, subsitute accordingly
3 > close the folder and right click on it and select Send to Compressed (zipped) Folder.
4 > use the "manage attachments" in the "advanced" reply window to upload that zip file here as an attachment.

This might point us to a non Microsoft driver causing the error, if one exists for it.

When I awake my computer from sleep mode, one of the data drives is missing (it is gone from This PC (formerly My Computer)). If I go into Device Manager and select Action > Scan for hardware changes then the drive is found and added back to This PC.

The controller is configured to RAID instead of AHCI in the BIOS (because I have a RAID 0 attached). The affected drive is not in a RAID array.

So I built my computer like last week and I was trying it out Crysis Warhead on max. Then saw my temperature thing on my case and it said 43degrees celcius, and I thought, woah thats hot, and i opened my side board but when i did, my whole computer shut down. I think i might have tripped the motherboard 24pin wires some how and it lost power and everything went down. Then when i tried booting my computer again, my monitor says in powersave mode, please move mouse or something. i moved my mouse key board and everythign and even rebooted my computer several times. I've tried many things but it won't work. Im having someone look at it in a few days, but you guys might know whats going down.

I've tried rebooting countless times.
I've repositioned my ram.
I replaced my video card with my old one, plugged vga in nothing.
i tried my monitor on my lap top, monitor works. not the monitor's fault, though i hoped it was because its easier to replace that then a mobo or whatnot.
and sometimes, when i boot, it shuts off after like 5 seconds and re-boots it self.
My keyboard light and mouse lights are off. my fans and psu and cpu fan are on and my graphics card fan is on.
maybe its harddrive malfunction? >< i hope not. but i dont think so, the monitor doesn't even turn on!

My Yoga 710 laptop puts my external monitors to sleep once I connect them with a cable and adapter.  Each external monitor I have tried recognizes they are being plugged into a computer, because its display window will change from "no cable/computer detected" to "monitor is going to sleep".  The laptop, however, stopped recognizing that it is being plugged into an external monitor.  In addition to trying different monitors, two different microHDMI adapters, and three different cables.  I have worked with Microsoft, Lenovo, and Geek Squad to update the drivers and replace the motherboard.  Is anyone else experiencing this? Any suggestions?  This error began soon after I updated the laptop's drivers for a problem it had communicating with my wireless printer.

Hi, I am using the default settings in the Power and Sleep settings. The notebook is plugged in to AC Power. It is plugged into the thunderbolt docking station with mouse, keyboard and ethernet connected. The display is supposed to turn off after 10 minutes and the computer is supposed to sleep after 30 minutes of idle time. It I do not connect an external display, everthing works fine. If I connect an HP27sv monitor to an HP DVI-to-DisplayPort adapter, and plug that into the docking station, then I get the following behavior. After a reboot, everthing works fine up till the first time the computer sleeps: The display turns off after 10 mintues and wakes up fine. After 30 minutes the computer goes to sleep.  However, once the computer has woken up from sleep mode, then it always goes back to sleep after two minutes. No matter what I do with the Power and sleep settings the computer goes to sleep after two minutes of idle time. I can also reproduce the bug using the sleep button on the keyboard: Connect external display Press sleep button on keyboard, computer goes to sleep Wake up computer and sign in Wait two minutes with no activity, computer goes to sleep again (should be 30 minute wait) This system has the NVidia Quadro M1000M display adapter for the docking station display ports. NVidia driver version is 354.86

Hi, my external display lost ability to fall into sleep after inactivity timeout is reached. It just turns to black screen, apparent the display is active (I don't use the blank screen screensaver). The display only switches to standby if I unplug the signal cable. Withal it was able to switch into full standby earlier. So something had to change.

I did walk through monitor menu to find if there's some settings for power saving mode, there's none.
Connected via HDMI. Have searched a bit for this problem and found only this be closest to my problem: windows 7 - Monitor doesn&#39;t sleep on power off - Super User but the topic doesn't have a solution for me (I don't see any DPMS or power off options, probably for that BIOS is in UEFI mode).

powercfg /availablesleepstates gives this report

The following sleep states are available on this system:
Standby (S3)
Hybrid Sleep
Fast Startup

The following sleep states are not available on this system:
Standby (S1)
The system firmware does not support this standby state.

Standby (S2)
The system firmware does not support this standby state.

Standby (Connected)
The system firmware does not support this standby state.

Any resolution on this issue?

A:External LCD display won't fall into sleep (only blank)

Do you have another monitor to try? It sounds like the graphics card realizes the computer is idle, and so it stops sending data to the monitor, but the monitor seems not to understand it needs to go into standby mode.

Swapping monitors with another computer will reveal if the problem is with your monitor, or your computer, depending on if the problems moves to the 2nd computer with your monitor, or stays with your computer with the 2nd monitor.

I am using a brand new Lenovo P51 with 64-bit Windows 10 with a NVIDIA Quadro M1200 video card along with an external monitor (ASUS VS228H-P) connected through HDMI. When my computer goes to sleep, my second monitor turns off. When I wake up the laptop, but 2nd monitor is no longer recognized by the machine and I am unable to use the display. I have tried a number of solutions already:1) I have tried selecting "extend display" under F72) I have tried using the detect display button in System/Display Settings3) I have updated my drivers for both display adapaters (intel graphics 630, and NVIDIA Quadro M1200)4) I have turned the monitor on and off,5) I have cycled through the input options on the monitor while it is on6) I have plugged and unplugged the HDMI cable The only solution to reconnect the monitor I have found is to reboot the computer which is impractical for me while I am using the machine (I am running programs over multiple days and rebooting is not impossible). It is also impractical to turn off sleep mode on the machine - the whole point of having sleep mode is to save my screen and reduce power usage. I also use sleep mode for security - I want my laptop to lock so that someone can't just pick it up any time and use it. I also read somewhere that someone was able to turn off and then turn on the display adapters to reconnect - but this is a ridiculous fix I won't repeat over and over again. Outside of these solutions, has anyone found a way to make Win...

Hi everyone, when I wake my Yoga 900 from sleep mode, it takes around 6 seconds for the screen to turn back on. That's reasonable. My girlfriend's Yoga 900 however takes only 2 seconds, we bought them around the same time, same system etc. Also, since yesterday, when the screen goes black after the set time (e.g. 5 min) and I touch the touchpad or press any key it also takes around 7 seconds before the screen goes back on which is way too long since before it reacted alost instantaneously. What might be the issue? Could both things be connected somehow? Thanks for any help!

There are countless threads and posts with consumers/owners expressing issues with Lenovo ThinkPad workstations which are not delivering on expected (marketed) features/functionality, due to software related issues. Namely:
- ThinkPad Workstations lose support for external monitors when 'awoken' from Sleep mode and/or Hibernate mode
- Switching the graphics card leveraged by the system has no impact on performance (issues persist)
- It seems the only recourse is to restart the affected laptop and/or not use the features and functionality available on the device
--- this is also the most common "solution" presented to users in threads and/or users are advised to not to use multi-monitor configurations outright
Although many systems may be impacted, this post focuses on issues on the ThinkPad P50, the latest Workstation, which happens to have a NVIDIA Quadro M2000M graphics card.
- All BIOS/Firmware/Software is up-to-date as of writing, however, the issue persists
This sort of performance from a modern business-grade workstation is unacceptable.
As an owner of the Thinkpad P50, I would like to see this issue investigated & fixed before 2017 -- given there are threads/posts that go back, even beyond this year. This seems to be a known issue that's being willfully ignored by Lenovo and/or Think Engineering. If the issue cannot be resolved, then Lenovo needs to assume responsibility.

And what is the problem?
I use Thinkpad P70 with M3000 and WIndows 10 between two locations daily, each with different number monitors and different DPIs (one with 3 x 1920, one with 2 * 4K), sleeping while in the backpack, and no major problems. Rebooting maybe once a week, for non related reasons.
BIOS is set to Discrete only.

i have an external display connected via dcmi port. when computer awakes from sleep mode, the display is not recognized. even if i disconnect/reconnect the device from port, it is not seen. i must restart computer before device is recognized again. i also have similar problems with 10 port usb hub, but disconnect/reconnect fixes it.  Both fixes are overkill.  I didn't have any problems with these connections on old laptop. please advise.thx.

I have a Y2P which I upgraded to Windows 10 a few months ago.  I have updated all the drivers and the BIOS, done the registry fix for the DPTF driver discussed here to fix degraded performance in non-laptop mode, and turned off adaptive brightness.  Most of my use is plugged in with the machine in stand mode, with a second monitor and BT mouse and BT keyboard. After doing the DPTF driver fix, I noticed that a few times when I was away from my desk, the machine rebooted spontaneously due to a critical error which seemed to be from overheating, so I set the power mode to sleep after 10 minutes idle.  Most of the time, now, it has no difficulty waking up.  But so far twice when I have woken the machine, the primary monitor is off, and can't be found by any setting or control panel, and the auxilliary monitor behaves as though it is the primary one.  This can be fixed by rebooting or by unplugging the second monitor, and then plugging it in again. Also, a couple of times now, when the machine wakes, the primary monitor is very dim.  The first time it happened, I went into settings and made it brighter.  But when it happened today, despite my increasing brightness to 100% (through the keyboard, through the display settings, through whatever I could find) the screen stayed very dim.  I finally rebooted, and the screen returned to normal. Does anyone have any suggestions for keeping these things from happenin...

I am using a 2013 Ultraslim Docking Station with my Elitebook 1040 G3 and have a Dell P2417H monitor. When I put my laptop on the docking station, almost without fail, the local display turns black with just the mouse cursor on it and the external display stays in sleep mode.  Most of the time, if I send the laptop to sleep, then wake it up again, the external monitor wakes up.   Why do I have to go through this process twice EVERY time I put my laptop on the docking station? Is there anything I can do to resolve this? I have replaced the docking station and the issue is still present. A co-worker uses the old docking station and experiences no problems.

HiI have a Dell monitor P2419HC and using it with Lenovo T480s via USB-C port. (it both charges the laptop and display)But, when waking up the Lenovo T480s from sleep mode, the P2419HC won't recognize the signal and says "no USB Type-C signal from your device".Reconnecting the USB-C cable from the Lenovo T480s solves the problem. When asked in Dell forums i got the following response:"By disconnecting/reconnecting the USB Type-C cable from the Lenovo T480s, you are forcing the Lenovo T480s operating system to "initiate" the USB Type-C handshake to the P2419HC. The Lenovo T480s hardware and operating system are responsible to make the connection handshake to the P2419HC. The P2419HC just waits for the handshake. The P2419HC does not "initiate" the handshake." link:https://www.dell.com/community/Monitors/P2419HC-Lenovo-T480s-no-USB-Type-C-signal/td-p/7279448 Is it fixable? Thanks!
