This problem seems to be getting progressively worse. When I'm on the computer the screen sometimes breaks up, looking a little bit like I'm looking through a venetian blind with bands across it. The computer will freeze up and sometimes then go into Power Save mode. When I try to reboot, 7 out of 10 times it will go immediately into Power Save Mode and nothing I try gets it working.

Re: Monitor goes into Power Save mode unexpectedly
What are your settings in Control Panel, Performance and Maintenance, Power Options? Do you leave your pc on all of the time or do you turn it on just when you need it? If you are getting lines on your monitor, it is possible that it's starting to give out on you. Please don't try to fix a monitor unless you know EXACTLY what you are doing. It can be very dangerous.

If that's the case, first check if your computer itself is on. If it is, then you need to check the connection from the monitor to the computer. If the connection is secure, then there is another issue going on. At this point, I would recommend reseating your RAM and your graphics card (if you have one). If you need help on that simply ask another question or try Google.If you follow all of these steps and the computer still isn't working, I suggest having a IT Professional look at your computer.
Dell monitors automatically go into power-save mode after a preset
amount of time when the computer is inactive. The Dell monitor will go
completely black, instead of showing a screensaver. This doesn't mean
that your Dell computer
has shut down. Instead, this allows your monitor to essentially turn
off until it's needed again. You can change how long it is before the
Dell monitor goes into power-save mode by changing your display
any key on your keyboard or move your mouse. Either will turn off
power-save mode. Alternately, you can press the power button on your
Dell computer tower or laptop.
any key a second time if the monitor goes from power-save to stand-by
mode. Stand-by mode allows the screensaver to appear.
your user name and password into the login prompt if your computer
requires a login. Press "Enter" to begin using your Dell computer.
the display settings on your Dell monitor to prevent your monitor from
going into power-save mode prematurely. Right-click anywhere on your
desktop and choose "Properties." Click the "Screensaver" tab and press
"Power." Beside "Turn off Monitor," choose a time amount from the
drop-down list and press "Apply."
The reason your computer is in power save mode is because the little battery inside your tower is going dead. It needs to be replaced. It is a small battery about the size of a nickle inside your tower. Change the battery and it will solve your problem.
Try tapping the F8 key while booting the computer, you will get the start up menu, choose safe mode, when you log on, go to the display settings, that is right click on the desktop, properties, screen saver, advanced and make sure that hibernation is off, along with turn off disks or whatever , probably see turn off monitor after XX minutes, I make ours 15 minutes (150 computers and servers), I don't let the disks turn off. Choose always on also, not home/office. Try this and see if these settings help.
Actually, it most likely is not the monitor which is in "power save mode", it is the computer itself.
When you cannot get a computer out of "power save mode" by any other means, typically the cause is that the button-cell-type battery of your computer, which is located on the motherboard, is empty.
Usually, this happens on a computer which is a few years old, since its batteries will have run out after such a long time. (The motherboard battery is used to store various settings when the computer power is off, such as date and time. When your computer detects this battery is empty, it goes into a low-power mode).
The solution is to replace the button-cell battery on the motherboard of your computer:
open the case of your computer;
visually locate the motherboard (the main electronic circuit board) of your computer;
visually scan the motherboard for a button-cell battery (it looks like a digital watch battery, but a bit larger);
remove this motherboard battery from your computer;
restart your computer: it should now power up normally (you may get some warning messages during the start-up sequence, but ignore them);
set the date and time of your computer using the "Date and Time" control panel;
you can now use your computer normally, but you will lose date and time settings when you disconnect the computer power cord, since there is no motherboard battery present to store them;
take the motherboard battery to an electronics store and get a replacement;
install the new battery in your computer;
restart your computer, and set the date and time again; the settings will now be saved using motherboard battery power.
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.
