WE HOOKED UP MY OLD DESKTOP YESTERDAY AND THE MONITOR KEEPS FLASHING POWER SAVE MODE. How do we get out of it? I am on my husband's computer now.

read the monitor manual.. Did you try unplugging it and see if it reset to default when you plugged it back in?

all monitors worked new ,yours is 2007 made,
and most old ones are dead now, for sure older than 2010
and used 10 hrs a day the CCFL tubes are now DEAD or odd as H3LL.
blinking means sleep mode
is PC on , are PC fans all spinning?
turn on PC first, then after 30second (now) turn on Monitor last
if monitor is ok (PC not)the monitor tells you PC is dead.
so monitor is bad. what's new there? nothings ever.

CCFL are dead.
test and proof is here.

does it go into power save mode with your actually doing something. Like for instance if your typing does it go into power save mode? If its going into power save mode when your not doing anything on it then its as simple as a setting either on the monitor itself or in the power settings within your computer accessible by the control panel and screensaver

you can find it in safemode press f5 in boot up.

Prevent the laptop/desktop monitor from going to power saving mode:

Click on Start | Control Panel | Power Options.

In the Power Option properties window, click on the Power Schemes Tab

Set the Turn off Monitor/ Turn off Hard Disks option when on Power (and also Battery for laptop users) to Never.

Now click on the Save as... button and assign a name to this power scheme... Let us call it 'Presentation' and then click on OK.

That's it congrats!

Are you using usb keyboard and muse. if so your usb ports are dead

two options it is bust, get a new one, before it blows away your desktop unit as well, it has locked into system shut down and you might be able to restore it if connections and desktop software OK ... the latter may be dangerous ... get advice servicing please ... I blew up two computers and the notebook blew up itself and a computer ... power shocks ... the notebook was guaranteed repaired ... I just found out the charge cable was shorting but then it had been 10/100 base cable connected to the desktop !!!!! Mike

Hey there Celius,

Chances are the 'Refresh Rate' somehow got set too high for the monitor. On flatscreens , the result is a black screen.

If you have an old monitor (crt type) hook that up temporarily and reboot.

• Right Click the Desktop
• Click Properties
• Click Settings
• Click Advanced
• Click Monitor
• Lower the refresh rate or set at optimal
• Check the box 'Hide refresh rates this monitor can't display'

Shutdown, Switch back monitors and try it now.

Good luck
Mike

Most monitors will say "Power save mode" when they can tell through residual voltage that the signal lead is plugged into a machine, but there's no picture being transmitted. The four states of a monitor are:

* Off entirely.
* Switched on, plugged into a computer but no video signal being received - usually displays "analog power save mode" or "digital power save mode" for a few seconds, then blanks. Comes back to life the moment a video signal is received. This state is the default in full power saving mode.
* Switched on, not plugged into a computer. Some monitors don't display anything, some go into power saving mode, some fly "CHECK SIGNAL CABLE" or a similar message around the screen. Picture is restored when the signal cable is plugged back into the computer
* On fully, receiving an image, and displaying.

Hope this helps.

yeppers..that video card sounds bad..open up machine first, and make certain it's still seated properly.

got backup for that E machine?
