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.

my Toshiba laptop screen stays black, my laptop turns on but the screen stays black, I have tried many steps and none has proved, I wonder if it has to do with a cable or is the screen that needs to be replaced.

View 1 Replies View RelatedMy 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This does not have to do with an outdated driver(Most likely) It happened when I decided to decrease the brightness.
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!

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.
View 4 Replies View RelatedI'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.
View 2 Replies View RelatedLast week I took my laptop into Best Buy for a diagnostic due to some issues. After I picked it up, I noticed that every time I restart/turn on the computer, the wireless adapter turns on for a couple of seconds then shuts back off, and I have to manually press the adapter button twice for it to turn back on. I've never had this happen before.... and I reinstalled the OS last night at the recommendation of Best Buy because of the other issues, yet this adapter thing is still happening. The wireless works perfectly fine after I turn it on, but normally my adapter turns on automatically.
Does anyone know why this might be happening and what I can do to fix it? Right now it's just more of an annoyance that I have to turn the adapter on every time, but I'm worried that means something is wrong? Like I said, this didn't start happening until a week ago.
The laptop is an HP G60, running windows 7 home premium. The adapter is an Atheros AR5007.
Whenever my Sony laptop is turned back on and I choose IE, I am unable to connect.After I choose the diagnose connection problem button, I receive the message wireless capability is turned off and then a button to apply the fix..When that is chosen, it then turns the wireless on and provides access to the internet. I am using Windows 7 & Norton Internet Security. How can I correct it so that it starts with wireless capability.
View 8 Replies View Relatedi am having a weird wireless adapter problem. first of all the model of wireless adapter is tp- link ( tl-wn722n 150mbps ) and i am connected to tp-link router ( tl-wr740n ). so for the problem it's whenever i am surfing internet the wireless adapter just turns off.. it's either it's stuck on green light or no light ( it flashes green every 2 seconds when its normal ) sometime i can stay on the internet for 1 minute to 5 hours, but it's mostly few minutes. i noticed when i am reading news on internet or something like that it doesn't disconnect, but when i turn on Internet and watch a vid it suddenly drops signal. i have to unplug and plug it in again to get the connection back.
i have tried alot of things..i have changed ports,reinstalled all drivers in router, updated drivers, restetted settings to factory defaults, changing security, channels..nothing worked. the signal is pretty good i can still download with at least 1mbps of speed + the signal bar is full or 1 lower. another weird thing when i am downloading a file it doesn't dissconect i think it's just fine when i'm away from the computer.. but when i start googling,chatting on steam watching videos it just looks like it lost signal or something. also this is not the wireless adapter, because i had one before it started having same problem.. i bought this one at start it had same problem but it was 1 day, but after 2 weeks it started happening.. it's not overheating, i can be connected to internet in safe mode without a problem. also i am using a pc not laptop there are no viruses or malwares on my computer i have used avg and norton antiviruses for scanning, i also got 2 other computers one is loptop and other is pc none of them got such a problem.
I keep having to go back and adjust color and contrast every time my laptop wakes up from sleep. I keep hearing it's something to do with the drivers, but I tried going to device manager, right clicking on display adapter and seeing if there are updates and it says i have the latest installed.I just got this computer too, so you'd think it'd come with all the new drivers?
View 2 Replies View RelatedI have a Packard Bell Easynote TJ74, i bought it will a defect screen as i was planning to use my tv as the external monitor. For a few months it has worked perfectly. One morning i turned the laptop on and the laptop turned on with certain lights, but did not boot up and the screen which usually just has a white light did not show either, the hard drive lights did not light up but the heat sensitive buttons do work and light up but it's almost like the laptop is on but nothing is happening inside :S. I have the power supply constantly plugged in but the battery is not being used as don't want to over charge. After turning the laptop on and off multiple times it will finally start up correctly and the screen will light up just with a white screen and it will change over to the TV correctly.
View 1 Replies View RelatedI've got a HP Pavilion g series laptop, which has recently, when being turned on, powering up as normal by turning the light of the power button on and lighting the screen, then quickly shutting these off again, and then continuing to turn on as normal.It hasnt been doing this for very long, I have no idea whether it is a serious problem or not as I don't know anything about computers. I must add that I don't use my laptop with the battery in; I use it with the battery out as I mostly use it plug into the mains.

View 1 Replies View RelatedI have rebuilt my system twice now and my system is still turning off the display and powering down randomly. I have followed all the guide lines for disabling sleep mode and it still randomly stops running by turning off the display and powering down. I have to push the power button again and then Windows start up in diagnostic mode where I can select safe mode if I want.
View 9 Replies View RelatedI'm not sure if this is the right section to post this but, ever since I reformatted my laptop, it randomly freezes for about a second and a stuttering noise comes up. Then the screen turns black. It doesn't shut off because I could see the back light, it just turns completely black. What's causing this problem and how do I fix it? I checked the Event Logger and there are tons of errors and some critical kernal-power things.

View 5 Replies View RelatedI got my hard drive replaced a few weeks ago (dropped my laptop) and had an OEM version of Windows 7 installed. After getting home and re-installing all my drivers /programs, I used it like I normally do. Fast forward 2 weeks. I wake up and press the power button but the laptop is dead (this is odd because I usually put it in hibernate on a full charge before I go to bed). This continued to happen every day, my computer s dying overnight. Since last week I have been observing it overnight. Whether it be hibernate or sleep, my computer will turn itself on and become completely unresponsive (sounds like it's on but the screen is off. My test to see if it's frozen is to hit the 'num lock' key to see if it lights up). This event is a 100% occurrence. The only way to turn it off is to hold the power button for 5 seconds. Basically if I leave my laptop in sleep or hibernate, it will turn itself on at a random interval and immediately freeze. It will stay this way until it dies or I do a hard shut down. Also, if I leave it alone and go afk while working, it will go into sleep mode and freeze completely.
View 3 Replies View Relatedi have a hp pavilion dv6 6123cl with windows 7 home premium. since last week, it crashes randomly and the led that indicates whether wifi is on which is on f12 button turns red (wifi off). it has happened surfing on the web (in mozilla firefox) watching Internet videos or playing games with wifi on. after the laptop freezes, i turned it off with the power button, turn it on and the wifi does not reconnect.
only if i turn it off and leave the laptop for say, half an hour and then turn it on, then wifi is able to connect. i have been looking at event viewer near the time of the freezes and there's an error that indicates that a service called trueservices stops with event id 7034. also there is a warning that 'wlan autoconfig service has successfully stopped' with event id 4001. i am quite newbie with windows 7.
Just today i read a post stating that java has a bad virus. Know that i ran a malwarebites scan and it found 1 harmful item and i deleted the item. After restarting my computer from a prompt, my lenova v570 laptop now turns on with a black screen and a movable cursor right after the windows "welcome screen".
ctrl + alt + delete does not work
I have tried in safe mode and it turns on properly. So, i tried to do what others sujjested on other forums, which was to " roll back my graphics driver" after that, nothing has change.
i am able to turn my computer on for a few seconds but then it automatically shuts itself off after a few seconds but the thing is after letting it sit for a couple seconds it says something about how the clocks on my processor have been overclocked too high and asks if it wants me to restore them, so i do that and then the computer works fine, but then when i turn it off and turn it back on it does the exact same thing until i get that message again.i've tried manually reducing the clocks on my cpu even though they were already at stock clocks and that didnt work

windows 7 ultimate 64bit

View 2 Replies View RelatedI have three PCs that connect to my home network wireless and two others that connect wired through a hub. Periodically one of the wireless PCs will see the other wireless devices but not the wired ones. This morning I installed some Win 7 updates and after the restart my laptop can't see the wired devices. My wife's Win 7 laptop sees everything. So the problem is intermittent. I have fiddled with Advanced Settings in Network Sharing, such as turning Network Discovery off and back on again. I can't seem to find the silver bullet that will cure this problem when it occurs.
View 9 Replies View RelatedThis 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.

View 7 Replies View RelatedMy 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.

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.
View 7 Replies View RelatedIt 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..
