There are different types of cmos bat on different motherboard. Some are coin-type. If you have coin type bat for your cmos, get the part number and replace it.

It seems like it that you have a faulty power supply. Also the motherboard may be damged aswell, But most probably you can fix your PC by changing the power supply.

You may need to replace the cmos battery, its a cr2032 3v button cell
Make sure all your expansion cards and memory are reseated.
Make sure all cables are reseated.
your power supply could be bad

If that doesn't work try this


Here is my fix for the dell dimension 4400 amber light problem. It works!
replace cmos battery.
then unplug power cord form wall about 5-10 secs.
then plug it back in, wait 5 secs.
If amber light comes on, press and hold power button until it goes out.

(with light out, press and hold power button while amber light comes on and goes off again holding power button 2-3 secs after light goes out.) repeat whats in parenthesis until computer turns on
it should only take about 6, 7 tries.

After the computer boots, you may want to setup cmos or boot into windows.
After you shutdown, unplug power cord for 5-10 secs then plug it back in.
Press and hold the power button, computer should come on.
I found that's the only way to turn on the computer.
If you shutdown and don't unplug power cord the computer may not boot, mine didn't.
Strange I'd say

Dell Dimension 4100 won't stay switched off


Well try this to check some settings.
1. Reboot computer and hit F2 to go to the BIOS settings.(you may have to keep pressing F2 until you see that it is going into setup)
2. Once in the BIOS you will have to use the arrow keys to move around and there is a key at the bottom. Move to the Power section and hit enter.
3. Check and make sure that the settings for Power up on PCI/PCIE Devices is off.
4. Check and make sure that Auto Power On is Disabled.
5. AC Recovery is off.
6. If all the settings are done, hit ESC to exit the menu.
7. Arrow key over to Exit.
8. Hit enter and comfirm save settings.
If all the settings are correct, then you are quite possibly correct in it being the power supply.

Hope this helps.

One of my computers says that my "System Battery is dead" and I don't know what to do


system batery refers to a watch bater on the mother board used to keep time
it is as easy to eplace as a watch batery

Instructions Difficulty: Challenging Things You’ll Need:
  • Replacement Battery
  • Electronic Or Printed Backup Copy Of CMOS Settings
  • Backup Utility
  • Grounding Wrist Strap
  • Phillips Screwdriver
Restore the CMOS settings Step1If you've never made a backup copy of your CMOS settings (by using a backup utility program such as Norton Utilities or by printing a hardcopy out on paper), look them up in the printed documentation for your system or call the vendor of your PC. Restoring your CMOS settings from a backup will help determine whether the battery is the problem. Step2If you're using a backup utility to restore the CMOS settings, insert the emergency startup disk and follow the prompts. Step3Use the Setup utility that's built into your PC's BIOS to re-enter your CMOS settings manually. Restart your computer and wait for a screen that tells you what key or key combination to press for Setup. Step4If re-entering or restoring your CMOS settings solves your problem, then it's possible your battery is fine and the settings were corrupted by a virus or some other anomaly. If, however, your PC "forgets" the CMOS settings you just re-entered or restored after you turn the machine off (and then back on), you probably have a bad battery. Locate the dead battery Step1Turn off your PC. Step2Before opening your PC case, put on a grounding wrist strap to prevent discharging static electricity onto any sensitive components. In fact, throughout this procedure it's a good idea to frequently touch something metal (other than your PC) that's resting on the ground, to make sure you discharge any static electricity. Step3Open the PC. For most PCs, this entails removing a few screws with a Phillips screwdriver and sliding the case off. Step4Locate the battery on your PC's motherboard. This is trickier than it sounds because PC manufacturers have used many different types of batteries for CMOS settings. The most common are lithium, like the kind in watches, but they could also be a pair of AA batteries. Or they could look like two cylinders encased in red plastic: a silver box or a red and black box. Step5Draw a picture of the battery, showing its exact position on the motherboard. Remove and replace the battery Step1Examine the battery carefully to see how it's attached to the motherboard. Most likely, the battery is attached by a clip or with Velcro. Some older PCs might have the battery soldered to the motherboard. Unless you're confident with a soldering iron, don't attempt to replace one of these. Step2After you've removed the battery, take it to an electronics store to match it with a replacement. Step3Replace the new battery in exactly the same position as the old one, referring to your drawing (see Warning). Step4Restart your PC and re-enter or restore the CMOS settings.

Dell Dimension power problem


There are several different solutions for this as posted at this Forum.

http://www.tomshardware.com/forum/51352-2-dell-dimension-8400-wont-boot

1) A lot of people have just removed the Jumper for the CMOS and turned the Power back on and back off and replaced the jumper and/or removed the battery.

2) Several people have reseated the Memory and after booting back up it worked.

3) A few had to replace the Mother Board and CPU but in this instance they had to also replace the Case because the Dell case wasn't really fit for the heat of from the CPU.

4) I had the exact same problem and luckily replacing the Power Supply fixed this for me. I had to cut out the back of the Dell case for the toggle on/off switch but when I tested the old Power Supply it was only getting 5amps and this was causing the Amber/Orange/Yellow light to constantly flash.

I hope this helps!

Dell 8400 boot up problems


Hi,
There could be problem with the motherboard. You can try resetting the same.
1.Press F2 to enter the system setup.
2. Use the down arrow key and go to the option that says maintaince
3. Press enter and key down to the option CMOS defaults
4. Hit enter and reset defaults
5. Press escape and save changes and exit
6. check if the system boots up.


Before you perform the steps given above, unplug all external peripherals from the system like printers and webcams speakers etc. Your information is safe and there would not harm done to the information stored on the hardrive .


Thanks

Computer doesn't come on.


Easy check is: power the system off. Unplug the power supply from the outlet. Hold the power on button in for at least 10 seconds. Remove the CMOS battery. Reconnect the power supply to power. Attempt to power up. See what happens. If it comes up and asks for you to set config, power down, unplug the power supply and hold the power on button for 10 secs. Replace the CMOS battery with a new one (CR2032 button battery...about $5 for 2 in the Wal-Mart photo dept) and power on. The reason for the repetition is to reset the BIOS.

Sounds like you need to replace the CMOS battery on the motherboard. It will be a round silver disc about the size of a nickel.
