No Signal Monitor Going To Sleep
Sofie Kovalcheck
Hi BarbEl,
I'm sorry to hear that the CD installation did not resolve the issue. I would like to assist you with this, and come to a resolution. I would just need to know the full model number of your computer. I have included the 'Guide to finding your product number'.
Thank you.
My problem is rather silly - my monitor is brand new, has been working well for the past 2 days and I went to switch it to HDMI. Instead of HDMI, I accidentally switched it to VGA. I don't have a VGA cable so it is stuck at "No signal" then shuts itself off into power saving mode before I can even access the monitor menu again. I am going to attempt a 15 second hard reset on my tower. Hopefully it works.
I understand you accidentally indicated you wanted to use VGA instead of HDMI. The best thing to do if you cannot fix it on the Monitor menu. Use f11 on start-up and do a system restore. It should be Ok to restore it back to when it was working correctly.
I have read many threads on many forums and see everybody helping with instructions on how to change your settings. For those of us that just has one monitor on the computer we are trying to work on it didn't really help.
I am having the same problem with my HP 2511x as many others (as I have now researched). The monitor does not detect a signal to the pc. I have switch the DVI cables suspecting there was an issue with the cable, but had the same results. I then switched the DVI cables and replaced with HDMI cables and again ran into the same issue. I then bluggeda different monitor with DVI connection to my PC and immeidately had an image. Therefore the issues exists with the monitor and not the PC or the graphics card within the PC. I purchased this monitor about 10 months ago and certainly did not expect to get a LEMON from HP.
What I do not undertand for the life of me is why HP has not issued a recall for this model as there are a MULTITUDE of troublsehooting requests out there which all reflect the SAME problem. I suspect HP is quite aware of an issue with this model and I truly hope that they will either repair or replace at no additional charge to me.
Have subject 2270 Monitor. After 3 years suddenly black screen and sleep, and check video cable message if monitor was manually awakened. Tried unplug reset of monitor . . . no solution. Unplugged power to turned "on" (at CPU plug end) CPU for about 10 minutes. Monitor power was left "on".Plugged power back into CPU, activated On/Off switch to "ON" (old USAF trouble shooting wording), and everything spooled up, and is back to Normal. It took about 2 minutes for everthing to get to normal "start up" screen (HP Vista crap), then another minute+ for E-mail, and another for the Nets. But so far all is well after the CPU Power RESET technique.
The previous time I could bypass this problem by connecting from my laptop to my Z230 HP desktop with RDP/MSTSC. The monitors (2) would then receive the signal again. But now even this trick does not work anymore. Both monitors are permanently sleeping and i can only work on my HP desktop from my laptop with remote desktop.
we have 3 desktops that we know work, we just moved and are trying to hook them up and 2 of the 3 are saying no input signal and then immediately say monitor going to sleep. we bought new vga cables last night nfor them and are still getting the same thing.
Sleep mode is a power saving state that stops all actions on the computer. Any open documents and applications are moved to the system memory (RAM) and the computer goes to a low-power state. This is similar to pausing a movie DVD. The computer is still powered on, but uses less power. Devices such as monitors also use sleep or standby mode to reduce power consumption.
So just today, I have this problem where my monitors does not display anything after start up. I would turn on the CPU and everything runs fine (fans, power supply, etc) but my monitors stay undetected as if my computer was never turned on.
So far nothing has worked and I'm completely stumped. Everything was working fine until my computer randomly crashed darker today and then froze in start up to now not displaying anything. Any help would be highly appreciated and thanks beforehand.
All i've done is switched on gaming boost and A-XMP in my bios settings and got a blank screen showing no signal. I've tried everything mentioned in that question but haven't succeeded. Help me please.
It could be your PSU. My monitor would intermittently should the desktop but thengo black with the words "NO SIGNAL" and the monitor followed by going to sleep. Sometimes rebooting cleared it up but when my furnace went dead a few days ago the house temperature dropped from 70 to 37 degrees. At that temp the monitor never came on. I switched out the monitor with another and had the same results. Thinking the temperature was a factor I ran a hair dryer on high for a minute and suddenly the picture on the monitor came on. The picture stayed on for about 5-10 minutes then went black as the power supply cooled. I warmed it again and the picture resumed. At that point I felt very confident it was the PSU so I ordered and installed a new one and the monitor and computer are both working like new.
Are you getting post beeps on startup ? If not you may be dealing with a power issue . Just because your fans are running and your motherboard light comes on doesn't mean you have enough power in the power supply to run the machine .Power supplies can die slowly and still appear ok .If you have access to another power supply try changing it out . You may also want to try a different monitor or test your old monitor on another computer. depending on your motherboard you could try resetting the mem button common on Asus boards. Also you mentioned you've disconnected the power and that you've held down the power button for extended periods . Did you do this together? if not try unplugging from power and holding the power button down for roughly 60sec then plugging in and rebooting. Finally as dumb as this is going to sound but it happens to the best of us... is your monitor turned on and plugged in? Just sayin Hope something here helps and good luck
It could be your PSU. My monitor would intermittently show the desktop but then go black with the words "NO SIGNAL" and a few seconds later the monitor followed by going to sleep/powered down. Sometimes rebooting cleared it up but when my furnace went dead a few days ago the house temperature dropped from 70 to 37 degrees. At that temp the monitor never came on. I switched out the monitor with another and had the same results. Thinking that temperature was a factor I ran a hair dryer on high for a minute, blasting the hot air on the PSU and suddenly the picture on the monitor came on. The picture stayed on for about 5-10 minutes then went black as the power supply cooled. I warmed it again and the picture resumed.

Pc show display after removing battery or change cmos setting but when i shutdown and start again then again no signal error everytime when i remove battery or change cmos pc show display but only for one time
This is the first time I've ever decided to post a piece of advice to any website/message board because I think it would really help a lot of people. I had the exactly same problem after installing a new motherboard. I tried everything I could think of and all the tips I found online; to list just a few: updating my BIOS, reinstalling Windows 10, changing from DP cable to HDMI, reinstalling all my drivers, reinstalling just graphics drivers, plugging and unplugging my Nvidia graphics card several times, cleaning/vacuuming every single component (my comp is as clean as a whistle - looks brand new, trying all kinds of combinations in BIOS settings, etc - nothing worked.
And here is how I SOLVED IT! After reading some unrelated advice about the "turn on fast start-up" function in Windows 10 and reading about how it can cause certain booting problems, I thought I might as well give it a try, nothing left to lose. So, I went to Control Panel/Power Options and under "change setting that are currently unavailable" turned off the fast start-up. Voila, problem solved! I'm guessing there is was kind of incompatibility between my motherboard (Intel Desktop Board DQ77MK) and this particular Windows setting. After spending a week dealing with this issue and going out of my ever-loving mind, you can imagine my relief. I'll make sure to post this advice on as many message boards I can to help other miserable souls like myself.
@jayeff there are 2 different issues here, but the symptoms are the same. One is purely a hardware issue(RAM, PSU cables and other) the ohter one is a software issue. Iv'e eaten my nails over this. I swapped everything, mobo, psu, monitor, gpu, cpu bios update etc.. all of it and was still experiencing this when the system needed to auto reboot, for an update for example. NOTHING WORKED. The only thing that remained unchanged was Win10. This change in power options has worked for me. Finally..
