Lenovo G500s laptop monitor doesnt recover from power saver mode

Hii everybody,
i have been using this G500s laptop for an year or so...recently my laptop has started showing troubles with the screen saver or the power saver that comes by if i dont use my laptop for few mins..! when i dont use my laptop it goes to power saver mode and the monitor doesn not return back to power when i try to resume my work...!!! and interestingly i could hear the cooling fan running at high speeds and my laptop heating up... and it sounds like my whole laptop is working other than my monitor..!! my monitor is just a black screen..... and my system has began to slow down nowadays.. desperately need help on this..!! it has started becoming frequent

hi Murali993,
Welcome to the Forums.
Just to verify, when the machine goes into Power Saver Mode (Standby / Sleep), can you check if the power button is blinking (this is an indication that the machine successfully entered Sleep State).
If the power button is just a solid light and it's not blinking then the machine is likely not entering Sleep. In this case, consider doing the following:
1. Turn off Hybrid Sleep under Control Panel (Icon Views) > Power Options
    - Link to picture
2. Set the computer's power setting to HIgh Performance and disable the HDD's power management settings (see this guide)
3. If you have external devices plugged-in (eg. Flashdrives), unplug them then perform a clean boot (this procedure temporarily disables background services/apps that are running in the background that's possibly hanging up the system as these are normally terminated before the machine goes to sleep).
Let me know how it goes.
Regards

  • My Andoid Devices wil not wake up my printer from Power Save Mode

    I have an HP LaserJet Pro 200 color MFP M276nw istalled as a wireless network printer. I have various computers with XP and Windows 8 operating systems that wake up  the printer from Power Save mode without problems. I also can print wirelessly from my Windows 8 phone. The problem arises when I try to print from my Android devices. I have installed the HP All-In-One Remote App from the Android Store and they seem to have installed correctly. They recognise the network printer, tell me that it is Power Save mode but are unable to wake it up. Can anyone help with this one please?
    The Andoid version on the Tablet is 4.2.2
    This question was solved.

    Hello Jerends and thank you for your attention to my printer problem. My printer already has a fixed IP address so no need to go down that road. I managed to get around the problem by deleting the HP All in One App from my Android devices and replacing it with the HPePrint App. It's not perfect but does the job.
    Thanks again.

  • Dell U2414H Waking from Power Save Mode

    Hi,
    I recently purchased the Dell U2414H 24" monitor and have encountered some issues relating to my MacBook Air Mid-2013. When the monitor is connected to the notebook and the notebook is placed into sleep mode, the monitor flashed a note saying "Entering Power Saving Mode" then proceeds to Power Saving Mode. Yet when I come back an hour or two later, the monitor is continually cycling through this process. It will come on, display this message, proceed to Power Saving Mode and then repeat. Below I have embedded a video displaying the problem. I have the notebook connected using the included Mini-DP to DP cable connected to the ThunderBolt port of my computer. I'm running the notebook on OSX Mavericks 10.9.4. I have tried disconnecting the cable at both ends, restarting the computer and disconnecting power from the monitor.
    Hope you can help.

    How about if you open System Preferences Displays pane Display tab... Click on +Gather Windows+ on the display that is working. Then try adjusting things like resolution and +color depth+ on the non-working display to see if that has any effect.
    Have you tried disconnecting the power cord on the display for a few minutes and reconnecting it? Does the display have an on-screen menu, and a command to reset the settings on the display to default?
    A few more tests, if it still does not work.
    Create a new admin user account in System Preferences Accounts pane
    http://docs.info.apple.com/article.html?path=Mac/10.5/en/8235.html
    Log out and log in to the new account. In the new account, does the display work or not work properly? If it works in the new account, that would indicate some problem in your regular user account.
    Also try starting up from your Mac OS X installation disc. Does the display work when you are starting up from a different system? If so, that would indicate some problem in your current installed system.

  • W520 - now changes to "projector only" whenever display turns off in power save mode

    I have my W520 in a dock with an external monitor. The display is configured to Extend - the external monitor is primary, and the desktop extends onto the W520 screen. I don't have a screen saver. I turn off the display after 30 minutes of inactivity. Until recently both the laptop and monitor screens would turn off after 30 minutes, and then both resume when I moved the mouse or pressed a key.
    Recently, the system has started changing to "Projector Only" when the display turns off. After resuming from power save mode, only the external monitor activates, and the W520 screen is disabled. I have to use Fn-F6 to switch back to "Extend" to re-activate the laptop screen.
    I have rebooted and re-saved the power plan.
    Why has this happened, and how do I fix it?

    Hi, timg11
    I have a few questions so that I may gain a better grasp of this issue:
    1) What is your machine type and model? You can find this information on the bottom of your machine. It should be in format XXXX-XXX.
    2) What is your operating system?
    3) Does this issue occur is the computer is not in the docking station? (Please try if you haven't already).
    Thanks in advance,
    Adam

  • Mirroring LG Monitor stuck in Analog Power Saving Mode

    I have a macbook from 2006, and just attained an LG L1900J LCD monitor. When I connect the monitor to my macbook using a DVI to VGA Cable attached to a Mac mini DVI to VGA adapter I get no picture on the monitor and the message "Analog Power Saving Mode" appears before the monitor goes black and then switches into sleep mode.
    I have used the Switch application to try and fix the issue, and I have also adjusted the resolution many times as it appears my Macbook recognizes the monitor but an image just won't appear on its screen. I just ordered a Male to Male DVI cable and mini DVI to DVI adapter to see if a digital connection would work. Does anyone know if this will work or of another solution to my problem? Thanks.

    So I ordered a Mini DVI-DVI Dynex adapter and Male to Male DVI Cable off ebay for very cheap, and to my surprise, this set-up seemed to shake the monitor out of "Analog Power Saving Mode" into "Digital" since its a digital set-up and now I have a fully functioning, mirroring monitor. So I would suggest switching to DVI to correct your issue.

  • Dell 2407 Monitor entering power save mode immediately!!! :(

    I have a Dell 24" 2407 Monitor hooked up to my 24" iMac (white 2.16GHz core 2 duo). Problem free for the past couple of years, until recently, my monitor keeps going into power save (when the iMac screen is active.
    It's connected via DVI, and the funny thing is, is that the iMac still detects the monitor, but it's in power save mode.
    I plugged the monitor into the MacBook Pro and it worked fine. So I'm guessing it's either the Mini DVI to DVI converter is stuffed OR something is wrong with my iMac. I'll try another dvi cable, otherwise will have to go to shudder VGA until I get a new Mini DVI to DVI converter. Unless anyone else has an idea as to what's going on?

  • New LG Monitor Screen Image Keeps Shifting a few pixels left and right / goes into power save mode

    I just purchased a new LG Computer Monitor from Best Buy today and hooked it up to my PowerMac computer. Shortly after setting it up, the entire screen image started sporadically shifting left and right a few pixels. And then, at seemingly random times, it'll shut itself down, going into power save mode. I checked the cables to make sure they were secure and they seem to be. Could there be some sort of interference that's causing it? Or would it be the graphics card? My computer is only a couple years old. Please help!

    Do you have another computer you can plug the monitor into to test?

  • Monitor won't enter power save after playing You Tube videos...

    Hi
    An issue has  developed on my system in the last couple of months for which, after having done  a lot of research and testing, a solution has not been found. After playing  a video in You Tube, my monitor won't go into power save mode after the  prescribed time. It tries to go off for a second and the screen goes blank but  then comes straight on again. This happens after playing the You Tube videos in  Firefox, Google Chrome and Internet Explorer. I am running Windows XP  Professional and I have the latest version of Adobe Flashplayer installed,  the latest graphics card drivers, the latest version of direct x 9.0c.
    To clear this error, I have to go into my XP  power schemes settings and change it to another power scheme and then change it  back to my default power scheme. However, as soon as I play another you tube  video the same problem re-occurs.
    I have tried turning off hardware acceleration but this makes no difference. My graphics card is a Gigabyte gv-nx86t512h: http://uk.gigabyte.com/products/product-page.aspx?pid=2604#ov
    This never used to happen  until recently. It seems that there is something with the Flashplayer that is  not compatible with Firefox, Chrome, Internet Explorer etc.
    Any ideas as to what may be  causing this and what can be done to overcome it would be greatly appreciated as  it is a real nuisance.
    Many  thanks.
    D

    thanks for your suggestions.
    i found the solution/workaround from somone else on the adobe forums:
    Go to control  panel, display, screen saver, choose a random screen saver, set a long time  (i.e. 60 min, but always longer than your monitor shut off time), then select no  screen saver, and save! Simple as that…

  • Can I read Windows OS properties in LabVIEW (ex: Is monitor in power save mode?)

    Is it possible to read any properties from windows OS.  I would like my code to know if the monitor is in power save mode or not.
    I am using a touch panel and after the screen goes blank (power save mode), I don't want the user to accidentally push the wrong button (since he cannot see them).  The user has to touch the screen once to waken it up.  As far as I know there is no way for me to disable the touch screen while in power save mode so I wanted to try and disable the buttons when the screen is in power save mode.
    Thanks,
       Javier

    Look here.  At a bare minimum, it loks like you need DevicePowerEnumDevices and GetDevicePowerState.

  • Macbook pro goes into power save mode with dell sp2208wfp monitor.

    I have a macbook pro and am trying to connect it to a dell sp2208wfp monitor, I am using a hdmi cord and it goes straight to power save mode. My mac works on my roommates monitor and his PC works on my monitor but my mac doesn't work on my monitor. I've read the other forums and have found nothing. One guy suggested plugging the mac into a power source still nothing, any solutions before I try and sell this thing on craigslist?

    Had the same issue a few months ago when I tried connecting to external monitor, it is only possible to run external displays from a Macbook Pro while the power cable is attached, if you try and connect to external display without having the charger attached the external display will flash your desk top for a second and then your Macbook Pro will go to sleep.  Hence connect your charger every time you wish to connect to external display, its not a problem with your Macbook Pro, it's just the way of Apple. Hope that helps.

  • Monitor enters power save mode on start up

    PC keeps crashing in game, after it crashes it shows the message DVI power save mode on my monitor. Sometimes it even crashes on boot.
    It all started when i tried to update my bios with live update(yes I know wrong choice, after I did this is read all the wrong things about live update on google)
    So i flashed my bios with an usb drive to 1.8, but it's still crashing
    Setup:
    MOBO: Msi Z87-g45
    CPU: Intel I7-4770K
    GPU: EVGA GeForce GTX 770 4GB Dual SC w/ ACX Cooler
    memory: Corsair Vengeance LP CML8GX3M2A1600C9 4x4gb
    PSU: corsair HX750
    So I tried everything I could read about this problem on google, I even rma'ed my gpu and it still crashes.
    Anyone that can help me? or is the board bricked and should I rma it?

    Nope,  didn't do an oc,  sometimes after restarting several times i can run something. Like a game but after some time it freezes and gives a gray screen with 'dvi power saving mode'  after that nothing works,  no caps/numlock.
    I was thinking it was the gpu,  so i rma'ed it but when i had it back,  it gave the same thing.
    I thing it's the board,  pci slots or something
    Edit: it doesn't freeze with integrated gpu so it must be something with the slots?  Evga tested my gpu in another system.

  • U2312HM and second monitor = Entering Power Save Mode

    So, my monitor has not been able to turn on for about a week now. It shows that it's getting power, but after 3 seconds I get the message that it is going into power save mode. I am able to press some buttons on the monitor and a message pops up that there is no signal and to try typing or moving the mouse which doesn't work. I've attempted to change the input source which only leads to "No DisplayPort Cable - The display will go into Power Save Mode in 5 minutes.".  I have tried a separate monitor which is extremely less powerful and I get the same message that it's entering power save mode. Could this be a fried video card or what's happening here?

    Thanks for the reply Chris.  I do have both DVI and VGA out ports and I will be testing that today.  Not sure if this has anything to do with my issue or not but I might as well mention it.  I have 4 2 GB ram sticks which came with my pc.  I purchased two new 2 gb ram sticks due to some memory issues I was having.  The problem is, the two new ram sticks I had were not the correct size but I attempted to use them anyway.  Now prior to inserting these new ram sticks I cleaned my pc using air duster and a light suction vacuum cleaner, not sure if I got all of the dust.  Once I found that the ram sticks were not the right size I then reinserted my older ram sticks and this is when the monitor issue occurred.  A couple people had mentioned that this sounds like a bad video card, but could inserting wrong ram sticks affect the motherboard and in turn mess with the videocard?
    Also, roughly 3 weeks prior to the monitor issue, the lights on the side of my case are generally dark blue (but can not confirm if this is normal as I rarely pay attention to it.)  The only reason I bring this up is because the lights began to turn red, then a sortof clear light color progressively throughout the next couple of weeks, eventually not turning on at all.  Again, I've never really noticed the lights on my pc to begin with so this could not mean a thing.

  • PCI-GPIB does not like returning from computer power-save mode. I need to restart the application. Uggh! Customer not happy.

    It seems volatile memory is lost on the PCI GPIB Card. When the system returns from power-save, I cannot get to my GPIB instruments. I have to close the application and restart it. I've tried unregistering and reregistering the gpib globals and resetting the device interfaces (reissuing the ibdev command) without luck. I am using Visual Basic 6, but I also get the Measurement and Automation Explorer to fail in the same way, so I don't think it is my development environment.

    Can you change your power save settings? What operating system
    are you running?
    Also, some BIOS's have options for power save. For example, recent
    IBM's can be set to maintain power to all peripherals, or only to main
    memory. Of course, you would want it to maintain power.
    I suspect the GPIB board and its driver are completely unable to
    handle power save operation. It probably was never considered while
    it was being designed.

  • My iMac does not wake from power safe mode

    My iMac does not wake from power safe mode when addressed over the network from my Apple TV, until I send a "wake on LAN" command from a utility on my iPad. Is there anyway this can be done directly from Apple TV?

    Tons of similar reports all over the web - especially on ATV3 - but no solution, seemingly. Hopefully a software update will fix it one day soon. Sorry.
