PC Wakes But Monitors Don't?
Apr 7, 2012
This problem started a few months ago when I updated the video drivers on my NVIDIA card. What happens is that when the pc goes to sleep, either by my command or after timing out for inactivity, the pc will wake up when prompted by mouse or keyboard, but the monitors don't. I know the pc wakes because when tapping on keys or clicking the mouse button I will occasionally hear pings from the pc. I'm not convinced that the problem is NVIDIA's, but this does coincide with an updated driver of theirs.Ultimately, in order to get my machine working again I have to press the power button and restart cold. Also, and I'm not sure if this is worth noting, upon cold start, my Kaspersky and clock gadgets, which are normally placed in the upper-right corner of the right monitor, display in the left monitor somewhere off-center.
I'm diligent with keeping drivers updated, but I really have no idea what to do now. I'll post the stuff that may be relevant:Logitech wireless mouse M310 (unified w/ keyboard)Logitech wireless Solar keyboard K750 (unified w/ mouse)(2) LG monitors E2050NVIDIA GeForce GTX 460 video cardWindows 7 Home Premium (service pack 1)64-bit OSAMD Phenom II x4 945 processor 3.00 GHz8.00 GB ram

Every night I put my laptop to sleep but lately the laptop wakes up on it's own in the middle of the night every night. Anyone knows what might cause this phenomena ?

My computer wakes from hibernation.I�m using windows 7 x64. My BIOS doesn�t support any configuration settings about wake, and the LAN device driver states that it doesn�t support wake on LAN.It�s a Dell Lattitude laptop, about 2 years old.No events are relevant.This started about 6 months ago when I went out and updated all my drivers, so some driver is apparently having fun. I had already run for long enough when it started that I didn�t want to roll back, although I have tried earlier versions of the LAN, WAN and WLAN drivers. None of them have an option for disabling wake on LAN that can be checked.
C:>powercfg -lastwake
Wake History Count - 1
Wake History [0]
Wake Source Count � 0
C:>powercfg -devicequery wake_armed
gives no output.

My laptop wakes up for no reason after I put it to sleep. I unplugged my USB things and it still doesn't solve. When I do powercfg -lastwake it gives me this:
Wake History [0]
Wake Source Count - 1
Type: Fixed Feature
Power Button
This does not have to do with an outdated driver(Most likely) It happened when I decided to decrease the brightness.

Every few days my computer will wake from sleep in the middle of the night and to find out why I check lastwake from the command prompt and got this in attachment. I looked in WMC and didn't find any auto updating turned on. How do I turn this off? I really don't use WMC that much and don't need it waking my computer to update.

It is the most bizarre thing. Either it goes to sleep by the timer setting or I can use the "Start button" then select sleep. It closes up properly and looks all hunky-dori. Then between 30 and 45 seconds later, it wakes up again.
I heard it happening enough last night that I had to turn the computer off. I joke that it only needs 45 seconds of sleep and is ready for work again..

Obviously my problem is my pc wont sleep, it wakes a second or two after I press sleep. I checked google and this forum for a few hours and come up empty handed. Event viewer has no record of the pc even going into sleep mode, through the filter "power - troubleshooter".

My computer occasionally wakes up from Standby. I have a USB-based KVM switcher providing mouse and keyboard. When I want to put it in Standby, I first switch the switcher to my other computer, then I go into Standby by pressing the power button. When I want to use the computer again, I first switch the switcher back to the computer, then press the power button. Waking up from Standby spontaneously is not a major problem, as it is set to go back to Standby after several minutes. But I'm curious as to what might be happening.

I am having a most unusual problem where my system wakes itself from sleep when I walk by.. Sometimes randomly also but most times when I walk over to my desk it will wake by itself for no reason. This is quite annoying and i would greatly appreciate any help in identifying the cause.

When my laptop wakes up from sleep mode, my wireless turns off for about 2-5 minutes. The screen also flashes, the task bar switches from black to clear. When wireless starts working again, the screen flashes a second time and the task bar returns to black.

I have a small network consisting my work system and a HTPC. The HTPC spends all day sleeping, or at least that's the plan. It has a couple of maps to shares on my work machine, but not vice versa. Whenever I open an Explorer window on my main system it wakes up the HTPC, annoyingly. There doesn't appear to be a don't wake on LAN option (it's an Intel DH67GD motherboard). I could understand it if I had mapped some drive letters on my main system to shares on the HTPC, but that's not the case.

I have a laptop with a monitor attached. I use to be able to come in and move the mouse to wake up the system. Now, I need to open the laptop and push the power button. I have gone into System/Device Manager/Mice.... and there is no option to "allow device to wake up". My knowledge is limited, but I do understand some things. I just don't see what could have caused this change. It just happened out of the blue!

I have a computer running 7 Pro 64x that won't wake from sleep when the keyboard or mouse is pressed. I checked in device manager and both are selected to wake the computer and not allow it to power down the devices. They are both PS/2. The only way to wake the computer is by hitting the power button on the case.

Whenever I try to put my laptop into sleep mode, it wakes back up a few seconds later without me touching anything. Has anyone come across this before? I just reformatted my computer and this didn't happen before the reformat.

I've looked through the Advanced Power Settings options and not found something that appeared to be an issue to me. It still auto wakes up with Allow wake timers set to Disable and When sharing media under Multimedia Settings set to Allow the computer to sleep.I also ran powercfg -lastwake in cmdafter an automatic wake up and these were the results:

when I wake up my computer from sleep, it will turn on (all of the fans and lights start running) but there is nothing displayed on either of my monitors.I have my hard drive set to "never turn off" and this hasn't helped the problem.

I am running a Windows 7 HTPC, which connects to an LCD TV. Unfortunately, I keep getting automatic screen resolution and aspect ratio changes all the time.Each time I start the PC from from a complete powered off state, I have to go to the TV settings and change the aspect ratio. Many times, not each time, when I wake up the PC from from a sleep state, the resolution of the screen changes automatically from 1200 x 720 to the lowest 800x600.

I've had an HP dv5t laptop for about a year and a half (see specs), and so far (knock on wood) it's been pretty much perfect EXCEPT for one problem that has been happening on and off for the last several months. It occurs about once or twice a month for no apparent reason --- and I don't know if this this is a hardware or a software problem. What happens is that all of a sudden, for no reason my keyboard and touchpad/mouse are completely non-responsive -- and the only thing I can do is use the power button to shut down. When I reboot everything seems fine, until the next time it happens, a week or two later. It can happen when the laptop is running, but more often it happens when I open the lid after the system has been in Sleep mode. (I keep the laptop in 'Sleep' mode all the time when the lid is closed, and only fully "shut down" once in a while.) Everything seems to load properly --- the Desktop looks perfect and all my apps/icons are there, but the mouse won't move and the keyboard doesn't respond.

I am using a very cheap receiver from Amazon with the PC Remote Control drivers provided by Eventghost. From my other readings the best way to identify the remote is the presence of [URL] in the GUID. My problem is this. When I put the computer to sleep and begin watching another source, the commands from the television remote are detected by the IR receiver and wake the PC. Is there any way to select which signals would wake the computer?I currently have the power management settings configured to not allow the IR receiver to wake the computer and use the power button to wake it?

I've got a pretty regular and predictable usage pattern with my computer - quick logon in the morning to check emails, go to work, use computer at night, restart before bed.The computer is set to sleep after three hours of inactivity. So in the morning it will be sleeping, then when I get home from work same thing. Sometimes not; never figured what wakes the computer, but 90% of the time, that's how that works - it sleeps after three hours, and stays sleeping for several hours.However, this week I noticed that the computer seemingly never sleeps. It's always on when I come by it, including in the morning, and when I get home from work.Checked the system log in the event viewer for events 1 (wakeup) and 42(sleep), and I noticed that, into the morning of 9/16, the normal pattern of several hours of sleep was adhered to. Since 9/16 though, every sleep period lasts about 2 1/2 minutes. That is, it goes to sleep (event 42), and then within 2-3 minutes, it will wake up (event 1).There have been no Windows updates in that time that would affect this. Definition updates for Windows Defender on 9/18 and 9/21, and KB2744842 (security update for IE 9 on x64 systems) on 9/22, but nothing happened, including no new software installations, on 9/15 or 9/16.So why is my computer suddenly waking from sleep almost immediately?

When Windows awakens I have sound only from the right side. If I do a restart the sound comes from both right and left. I have reinstalled audio drivers (onboard Asus N4A78 Pro VIA). But when it falls asleep and awakens, same problem no sound from left side. I originally thought it was my 2.1 speakers and replaced them but have same problem with these.

I'm positive that I'm not bumping into the mouse or anything to accidentally wake it as I make sure to turn my wireless mouse off once I've finished a session on the computer. and often times the computer will wake in the middle of the night. I will select sleep mode before going to bed and when I wake up it will be running like normal

I have windows 7 Home Premium and I am facing some problems with Hibernate and Standby. The first Problem is that my system doesn't hibernate but instead it just perform a log off. The second problem is that when I put the system in standby, it wakes up automatically after 2 to 3 hours which makes a serious problem if my laptop is in the bag.

My desktop won't stay asleep. It consistenly wakes back up after approximately 50 seconds.This happens regardless of whether I manually select Sleep from the start menu, or if it goes to sleep on its own.

I've had this problem every since I built my new rig - the thing either won't go to sleep, or will wake back up if I put it to sleep manually. It doesn't do it all the time, but it happens enough to be an annoyance.
Here's what powercfg says after it wakes up:
Code: C:UsersCharles>powercfg -lastwake
Wake History Count - 1
Wake History [0]
Wake Source Count - 1
[Code].....

This has been an ongoing issue with my computer only waking from sleep half the time. The other half I need to actually power cycle my machine in order for it to wake. I know when it is going to wake properly because I hear the DAC on my Asus Xonar Essence STX Sound Card click on and if it's not going to work obviously I don't hear the click.I have tried the following:
- Complete system rebuild with new hard drives, reinstall of windows
- All drivers updated and bios updated (I have been through a fair few driver updates because this has been an issue for over a year)
- New Memory installed
- Played with as many power settings in the bios as possible
I am really starting to think it is a hardware issue with either my motherboard or video card but don't have a spare of each of these and don't want to buy new stuff just to test it.
Here are my Specs:
Motherboard: Asus P8Z68-V Pro
CPU: Intel i7 2600
Video Card: Gigabyte 6950 (in eyefinity with 3 Monitors)
Sound Card: Asus Xonar Essence STX
HDD: 2 x 240GB Sandisk Extreme SSD (Raid0)
Memory: Kingston Hyper X 4x4GB (16GB Total)
PSU: Seasonic X Series 750w
Monitors: Samsung MD230x3 (3x23") 2 connected via DVI and 1 via DisplayPort
As mentioned the hard drives and memory were replaced so it can't be either of those. Also it can't be any settings because it does wake via my keyboard/mouse half the time. It is also hard to troubleshoot as it may work 3 times ok and even wake form sleep overnight but then I could leave it for 30 mins come back and it won't wake that time, there is no pattern that I can make out, not sure what else I can do to troubleshoot this but it is really annoying as my computer gets a lot of use and would rather put it to sleep than continually turn it off and on.
