Can WindowsXP turn off a monitor completely?

[Richard]

I know that my PC can make my PC go into a standby condition. What I mean is
that the indicator light go from green, to orange. But, what is hapenning is
that after a short while my monitor turns off completely. I mean, the
monitor state indicator light goes completely out, it does not just go to
orange from green. Can WindowsXP be causing this? This morning I put the
monitor on without turning on the PC. Naturally, the monitor indicator went
from orange to green because of no signal. Then I put the PC on and the
monitor state went to green. But, after a short time, the monitor was
turned off. And I mean turned off, not just "in the orange state". TIA.

Try a different monitor as a test to see if the monitor has a problem.
It could be that the signal's too weak, or there's no signal. But you
didn't say there was no signal to the monitor after you started XP.. If
no signal, the monitor could be turning itself off to save energy.

There is a good signal.

I left the monitor switched on overnight and of course, with the PC off, the
monitor was in standby. What I mean is the monitor indicator was orange all
night, not green. I switched on the PC this morning and after a very short
time, the monitor light goes out completely, and of course a totally blank
screen.

The only other way to get the monitor indicator to go out completely is to
press the on/off button on the monitor. Like I say, it's like the PC is
causing the monitor to be switched off. And I don't mean off as in putting
the monitor into an orange condition from green. In fact, to get the monitor
working, which I can after several attempts, I have to use the on/off button
on the monitor. Because when it goes off, it's like I touched the on/off
button. I have to physically switch the monitor on after the PC made it go
off, by pressing the monitor's on/off button.

The following Kelly registry tweak isn't a solution for your problem; it
just suggests that, if after Standby the computer goes to the logon
screen where XP shuts off the monitor. Try turning off this feature as
a test. This might be done in the Power settings in Control Panel.

Also try a different monitor. Try a different graphics card.

What kind of a turn off is it, when the monitor indicator is made to go
blank? I understand putting the monitor in a standby condition, which might
be considered turning the monitor off. When that happens, the monitor
indicator is made to go orange, from green. But, that is not happening here.
To get the monitor on, I have to press the on/off button. Usually several
times before finally the monitor stays on showing green on the monitor
indicator.

Type of monitor? LCD or CRT?

It's an LCD monitor Packard Bell FT700.

Power cord have a transformer on it?

No.

Mains lead pluds into monitor.

If I unplug the video cable, picture goes (obviously) and when I plug it
back in picture comes back.

If the backlight had gone, I'd not be getting a picture, the monitor would
be totally useless.

I can tap he monitor, and stays on okay.

I just don't know what is is, that causes the monitor indicator to go out
and the PC to totally shut off, when the PC starts up. I don't even think
it's totally consistent either that the monitor turns totally off when the
PC is switched on.

How the heck can the monitor indicator go off. That's only suppossed to
happen when I hit the monitor on/off button!

I re-read the entire thread. The computer or Windows XP cannot in any way
cause the power to shut off on the monitor.
Some how the monitor is failing or you have a loose connection on your power
cord..

The only thing I can think of is this:

The monitor is on, and with no video, it's in power down mode. That state
can be maintained indefinitely.

I put the PC on, and after a few moments, when video is available, the
monitor seek to power up, but there is an intermittent fault in the monitor
and on power up the power suppy or whatever fails. Thus the monitor
indicator light goes out. But, if I mess about with the mains supply to the
monitor, (toggling the switch on the mains socket, not the switch
on the monitor), I can get it to be on. Thing is though, once it's on,
it stays on for hours no problem. I'm using the monitor now.

Then MS wasted their time adding "Turn off monitor" to the Power
Options.. if they'd only known there was no way to turn off the monitor,
they could have dropped all that "Energy Star compatibility" crap.

 

[Unknown]

If, as you say, you mess about the mains supply to the monitor, can you get
the monitor to come on? Orange indicator?
If so, you've found the problem.

 

[Unknown]

Not quite. The monitor turns off as far as displaying goes but the power
stays on. There is a switch on most all monitors for main power. It will
power the monitor on but you'll only have a black screen if the computer is
off..

I switch the monitor on. First indicator is green, then orange. I put the PC
on. I think first the monitor indicator then goes green, (as it would) then
the monitor indicator goes out before Windows is loaded.

Okay, now I press monitor on/off button. Nothing. So, I turn off mains
supply, then on again and then press monitor on/off button. Monitor comes on
now after having removed power to the monitor and restored it, but very
shortly indicator goes blank again. I may repeat this cycle 2 or 3 times and
eventually monitor stays on. For hours.

I've no idea what's wrong really. Whether the problem is the monitor or
something arising from the PC. I wondered if recent turning off mains
power to the monitor by cutting mains to it, caused something.
Before that, I just used to switch off the monitor using the monitor's
on/off button, but leave mains supply to the monitor on all the time.

I'll do more tests tomorrow.

Do you have an on/off switch on your monitor?

[Richard]

Yes I do.

BTW, I've had no problems today. Maybe it just cleared itself up.

 

[Unknown]

Sorry Richard, that question was meant for Elmo in response to his sarcastic
post.
Sometimes intermittent problems seem to clear themselves. An example would
be a loose power connection.
they will generally arc and in effect weld themselves together.
