Question about HP Pavillion s7420n PC Desktop

1 Answer

My computer went into sleep mode and will not wake up. When I turn the monitor on it says it is asleep and then goes black. I connected the monitor to an old laptop and it worked, so the problem seems to be my computer.. it is not sending a signal to the monitor or the keyboard. The mouse light is on when the computer is on, so it appears to be receiving a signal. HELP!

My monitor won't come out of sleep mode


when the computer enter the sleep mode, it is possible that the computer remove the check mark from this output activation.

When you have multiple ouptut like a internal LCD and output on a monitor, when going into sleep then waked up, laptop reactivate the internal LCD without reactivated the secondary monitor.

you could need to go in desktop property and reactivate the secondary monitor with the check mark listed : Activate.

If you only have one monitor but still a dual output card or two separate video card same thing can happend. try to connect the monitor on the second VGA or HDMI output and see if the video goes there.

then reactivate your secondary output and make it principal.

Does also happend when your computer is connected to a UPS power and your monitor is directly on the sector. (laptop issu also)

if a brief power outage arrive then the monitor shut down (no power) and the computer continu, as there is no monitor on the output any more Windows will automatically deactivate this monitor. when power goes back, this output is no longuer providing video. I suggest putting the monitor on a UPS as well.

You might have put the computer into hibernate; have you tried pressing the power button? It should wake the computer up if it is asleep or hibernating. It is also possible that your monitor cable is unplugged.

Sleep mode wakes up on it's own


turning off all the power saving items does not help this- it just ensures that it doesn't automatically power down your hard drive or shut off power to your monitor automatically when you aren't using it.
May I suggest Hibernation Mode as an alternative? this mode saves everything you are doing to disc and shuts your computer down completely. when you turn it back on, it will restore what you were last doing onto the screen, so you can pick up where you left off.
you can find more information on this and sleep mode from here: http://windowshelp.microsoft.com/Windows/en-US/Help/335c6a5d-0304-4af1-b135-6bf6c124dc111033.mspx#EZAAC

AOC Monitor says "no signal" and won't wake up!


This monitor refuses to wake up because it cannot find the signal from the computer.

When the light is amber, force the pc to shut down by holding the power button until all lights go off. Then, after about 10 seconds, power the pc back up again.

If this does not start your monitor, unplug all the monitors connections and plug them back in again. These things should reform the connection from the pc to the monitor.

good luck

Works when it wants to then turns whie with grey line in it


Hi

If only the monitor is going to sleep, then it could be a problem with the connection from the monitor to the computer or with the cable.

If the computer goes to sleep and if you are not able to wake it from sleep then check the sleep mode settings and also the power management settings for the keyboard and mouse.
You may also do a system restore if you are not able to wake the computer from sleep.
