Standby mode Something happened to the monitor. It stopped going to the standby mode or "save energy" mode after the computer been switched off (not the monitor). Normally it would go black in a minute! Now it keeps on, just a message comes out "No signal". Is there any way to troubleshoot?

Which operating system ?

Sleep mode on a Windows 7 PC saves power without you having to turn your computer off and without losing any work.

This option cuts the power to your monitor, powers down the hard drive and pauses all functions until you awaken the computer from hibernation.

Whether you have a laptop, desktop or workstation, putting your computer into sleep mode will lower your electric bill and save money!

Click the "Start" button in the lower left corner of your desktop. In the lower right corner of the Start menu, next to the "Shut Down" button, is a button labeled with a small, right-pointing arrow. Mouse over the arrow.

The Shut Down menu appears.

Point at "Sleep" and click on this option.

Your Windows 7 computer goes into sleep mode.

Wake your computer from sleep mode by jiggling the mouse.

There may be a delay of a few seconds before your hardware powers on.

All of your open programs are still open and your work is intact, just as you left it before the computer entered sleep mode.

Configure your Windows 7 PC to go into sleep mode automatically when it is not used for a certain amount of time.

Click "Start" and select "Control Panel." Click "System and Security."

Click "Power Options."

A menu opens.

Click on "Choose when the computer sleeps" and select the number of minutes of inactivity. You can also set a separate time interval to put your monitor into sleep mode.

If you set both to 10 minutes, then your PC and monitor will automatically go into sleep mode after 10 minutes of inactivity

Your Computer in sleep mode

First, save all of your work. Information in computer memory is not saved while your computer is on standby.

From the Start menu, select Settings, then Control Panel, then Power Management.

Automatically Putting Your Computer on Standby

Save all work before leaving your computer.

From the Start menu, select Settings, then Control Panel.

Double-click Power Management.

Set the times that you want your system to go on standby, to shut off the monitor and to shut off the hard disks.

Click OK. Your computer will go on standby according to the schedule you have entered.

Putting Your Computer in Hibernation

From the Start menu, select Settings, then Control Panel.

Double-click Power Settings.

Click on the Advanced tab.

At the When I Push the Power Button On My Computer screen, click Hibernate.

Click the Power button.

Hope this helps.

this only happens when computer is on standby or there is no activity by a human like movement of mouse. it is a built-in energy saving formula on all such monitors

The simplest thing to do, as it is a desktop computer, is go to the control panel, power options and set everything to never so the computer never goes into standby mode.
If this does not prevent the machine going into standby mode then we need to perform further troubleshooting.

DPMS (Display Power Management Signaling) is a standard developed to save energy and maximize the useful life of computer displays. By switching the horizontal and vertical sync lines on or off, a DPMS compliant video card provides the capability to place the monitor into one of four modes (Normal, Standby, Suspend, Off).
Each mode puts the display into a different powered state from fully powered up, to the Off mode. In the Off mode, only a small auxilliary circuit is running which monitors the horizontal and vertical signals to wake up the monitor.

1 check your power settings on your computer - your computer may go to standby after so many min of inactiveness. 2. check you monitor hardware setting (refer to your monitor manual) it might have built in energy save mode.

have you tried turning it on in safe mode? The F8 key at the top of the keyboard should give you that mode. Once you turn the computer on, continuously press F8 until it switches to safe mode-then go into 'control panel' and check settings for your monitor.

Hi,

Go to "start>settings>control panel>Display>Screen saver>Power>

Turn off monitor : Never
System Standby : Never

I have tested and its working fine.

Thanks,

There are 6 (reduced quality) capacitors in the BenQ Q9W5 which cause the screen over time to 'fail to sync' when turning on or resuming from standby.

They are;
4x 470uF 35v, and
2x 1000uF 16v.

I recommend the following replacements if you are in Australia (the ones I purchased from Jaycar only lasted 12 months);
(470uF) http://www.altronics.com.au/index.asp?area=item&id=R4865
(1000uF) http://www.altronics.com.au/index.asp?area=item&id=R5182

Hey,

I think this is more of a problem on your computer instead of the monitor, ofcourse you could try another monitor and see if the same happens. I suspect your computer goes into standby or hibernation on its own, and it does work fine if you reset the computer right?

if you go into power management again, disable or turn off hibernation completely, its on one of the pages.
Make sure its not set to standby, and also disable your screen saver.

Right click on desktop - properties - then screensaver. turn it to none.

Also you could look into the computer bios and make sure its not set to standby or hibernation from there. thats unlikely but you could check.

how to get into bios.. depends on the computer, right when you turn it on, on one of the corners of the screen you will get a message, press button to enter setup or bios. press that to enter bios when its presented.

look around the bios and poweroptions.


Let me know if you need anything else.


Thanks,
Ekse

yes it saves power.
