Have tried everything, motherboard, dell techs, resetting the cables, boards, memory, you name it. dell computer model 4400. mouse and keyboard fail to wake up the system and can't see anything except black. removed cmos battery, lights in back are green, green green amber. whick is listed as other in dell talk. someone suggested i press F8 and reboot while holding down. did no good. computer useless like it is. guess i will have to use only the computer at work, i can't afford a new one.
The pressing of the F-8 key while the computer boots up is called entering the Computer into the "Safe Mode". The F-8 key needs to be pressed several times at the second the computer powers on. When you get a DOS screen, go to "Last known good Configuration", this should help with the problem. The other solution i can offer is ounce you can get the computer up, go to System Restore, Restore to a previous point.

First off, we'll need to reseat most of the parts connected to the motherboard. That includes memory, video card, audio card and the others. What you need to do is to remove everything from the motherboard, connect them one by one. Once you have connected a part/device, try to boot it up. Do this until you have isolated the problem.
The hardware that is common to this issue that you're having is the memory stick. But, we really need to isolate the cause of the problem.
If your monitor is going in Power save mode it can be cause by following reasons.
>Check the data cable going from monitor to your Dell Dimension 4600 Tower is connected properly.The connector will be blue or white in colour.
>If the Dell Dimension 4600 Tower is powering on.
If still in power save mode then try to shutdown Tower and monitor,disconnect power cable from tower and monitor.Hold the power button on tower for 15 seconds.Then again try to connect monitor and check,if still nogo,and if tower has no lights then issue with motherboard or video card or power supply.If possible try connect spare known good monitor.
Your monitor is most likely fine. That message is the monitor telling you it's not getting any video signal from the computer.
If you're hearing all the sounds that go with a normal startup (usually a beep from the motherboard, then hard drive activity, finally the normal Windows startup sound through the speakers), and seeing that message, then you may have a monitor problem. You can try another monitor as a test.
The trouble is probably that the computer is turning on, but not actually starting up. This may be due to power supply, memory, processor or motherboard problems. Or one of the drives or expansion cards connected to the motherboard may be keeping the system from starting.
Make sure the memory modules are firmly seated in their sockets, and disconnect everything else but the power supply. If the motherboard, processor and memory are working, the system will start and you'll see something on the monitor. Then you can start reconnecting parts and see when the problem returns.
For that first open cpu cabinet then reattach the RAM memory. Pull cmos cell from motherboard for 10 minutes. Make sure motherboard is not ground with cabinet. Remove pci cards from motherboard if any . Reattach vga card if installed. reattach processor and its fan. Then when you power up the computer press F8 key then enter in enable vga mode then go to display property and set screen resolution to 1024*768 then apply and ok. Let me know if you need further assistance. Thanks for using FixYa.
I would look for the CMOS reset jumper on the motherboard, if there is one, and while PC is off take of the jumper, then put it back in place. But the more easier option is to just simply remove the CMOS battery from the motherboard, unplug PC completely first, leave it out for a few seconds, then replace it. If that works, you may come across some operating system start options to start the os, depending of what version you have make sure you select the Delete sleep mode data/hibernation data(something along those line), and start OS normally. By the looks of it you've tried everything possible, but last resort would be to try the resetting CMOS/removing CMOS battery. If all fails, try testing using a different power supply.
huh, so you did tried reseating all the components, memory, hdd, modem, if its still not working. the motherboard has gone bad, make sure for the future donot install more than 1 gb of ram in this machine. replace the motherboard.
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.
