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.

Do you mean the monitor's power light starts green and then turns orange when you turn it on? Most monitors will go to a power saving mode when they do not get a signal from the computer.
The Dell GX260 has a green power light when on. When the computer is off, the light is off. If it is green and blinking, then the computer is in a power saving mode.
Diagnosis: start with the obvious: is the monitor cable plugged into both the computer and the monitor (if not permanently connected to the monitor)? Are you connected to the active port? (You can add a video graphics card in most desktops. The motherboard video port usually needs to be disabled to use the card ports. If you plug in the monitor cable to the disabled port, it won't work.) Is the monitor set to the correct input? (This applies if the monitor has several ports. In that case, there will be a Source or Input button on the monitor.) Is the computer on? The GX260 has the power button on the front. (Other computers have the power button on the top.) There is also the power supply switch on the back which needs to be on.
Next try a different data cable between the monitor and the computer (if you can). Try a different monitor. If a second monitor works, than the monitor has a damaged main board. If the second monitor doesn't work, then the video graphics adapter has probably failed. Replace the add-on card, if in use, then boot in the safe mode to remove the old graphics driver. Then install the correct driver for the graphics adapter.
Note: the computer and the monitor should both be off when you connect the cables. Then turn on the monitor first and set it to the correct source before turning on the computer.)
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.
try unplugging vga cable and connect it back then try reseating the memory chips if system has two memory chips try with one memory . if that doesnt work reseat the grahpic card if u have any and reseat the cmos battery .
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.
