When I first started repairing things a mentor said always unplug anything you are working on. I found this to be a number one rule. You just don't know what still has power even though it says it's off. I've made this mistake too by not checking.
Okay. So...
Hopefully the power supply is just shutting down due to a drain on it's voltage and will be okay. Take out whatever you tried to install. Try it again. Take out anything not necessary to boot your computer. You'll need the video card if not integrated. If you have a bootable floppy, Unplug the hard drive. See if you get to a screen where you can go into the bios setup mode. You also might want to write down where things go back. This is especially if doing this with little sleep. Let me know..'ask me.'

Just dead, no power. not green light indicator power on rear


If there's no light on the power supply when you plug it in and you know that there's power to the cord then you have to replace the power supply. They are cheap and easy to replace. If you took it in to a computer repair shop it should only cost you no more than $75 with installation fee for a cheap replacement power supply. This machine doesn't need anything more than a low priced 400 to 500 Watt power supply since it's original one was only 200W. If you get a used one you should be able to get it for around $40 installed. Not sure where you are located but that's the norm in most of North America. Cheers

Precision T7400 power supply sounding an alarm


Did you open the case on your computer? It may have an open case alarm which is a small switch typically located near the edge of the cover you removed. Make sure the case cover is completely installed, then see if the alarm goes off.

Have the HP-D3057F3H power supply - plug it in an the green light is flashing quickly - PC wont turn on - Is the power supply buggered or is it something else


Most computer testing facilities will test your current power supply for free. A replacement is very inexpensive to replace. Bestbuy, MicroCenter, small computer shops and buy replacement from Amazon.com, newegg.com.. Just make sure you have the correct information for your replacement. The model number on the power supply would be your best bet in most cases. Good luck and have a great day. I buy power supplies as low as $15 dollars Generic

Power cord isn't working for Acer 5720


I have had good success with this notebook universal power supply. Just make sure that the clip you need is included with the item. Or you could buy an OEM (original equipment manufacture) model.

Hope this helps.

When the PC is turned on the light turns green for a second and then turns off. Nothing appears on tthe monitor. The monitor has an orange light steady


Since your green light comes on momentarily, you may have hope. Look in your manual or on Dell website to how to reset your BIOS chip to the default. You do this with the power off, unplugged. There is a 3 pin jumper which should now be in the normal mode. Moving the jumper to the clear mode for 30 sec. should bring the Bios to default. Should the monitor stay on, you will have to set the time and date and maybe a couple other tweeks. Good luck.

Mac Ibook Power supply problem


On Mac iBooks the orange light comes on when it charges the battery. Once the battery is charged it turns green. Im guessing the other powersupply was aftermarket or broken. EIther way, if it starts out green - recognizes the battery isnt full - turns orange for a while - then turns green when the battery is full, then the computer and powersupply are working perfectly. Enjoy your iBook!

Flashing Green Light on Power BESTEC Power Supply


Hi. NO, *********** board is not fried. I am not sure what the problem is but I do know how to fix it. It is usually casued by power outages (even if you have UPS supply).

1. TAKE OUT THE ELECTRICITY LEAD TO THE COMPUTER. Look inside the computer and find the bunch of wires coming from the power supply unit (the box thing at the top with the fan and all those colouted wires!).

2. Find where these wires run into a plastic connector and plug into the mother board. Unplug it.

3. Now plug the electicity lead back into the computer. The light should now stay ON.

4. Plug in the connector again... and boot up. Leave it run a while to convince it!

5. Repeat this process if it does not work first time.

This should fix your problem . It works for me when I get this problem.

Flashing Green Light on Power BESTEC Power Supply


This is an easy fix so here you go nice and simple:

Problem: Your motherboard circuit has been cut.

Causes: Power disconnected during operation. Power outage or short in the surge protector.

Symptoms: Flashing green light on both motherboard and power supply. System will not power on.

Solution:

Step 1: Ensure that both the power supply and the motherboard lights are flashing green, not solid or off.
Step 2: While the power is on, disconnect the power supply from the motherboard. This connection is the largest of the connections and should be listed as the 'P1' or 'Primary' power connection.

Step 3: Wait until the green light on the motherboard stops flashing and check to ensure that the green light on the power supply is now solid. If it is not solid, disconnect the power to the power supply and wait until the light turns off completely. Then reconnect, it should be solid now.

Step 4: While the power is on, reconnect the P1 connection to the motherboard and you should now see that the light on the motherboard is solid.

Step 5: Power on your PC. The problem should not persist.

Warnings: If the power supply light remains flashing after you have restored power to it while it is disconnected from the motherboard, it may be a system failure in the power supply itself requiring replacement. Always be careful when working with an active or live power machine.

I hope this helped! Good luck!

green-white for front panel Power indicator LED , Blue-white for RESET Switch , Orange-white for POWER BUTTON , Red-white for HDD LED . The berg pin header on the motherboard will have these legend printed just beside the connector or due to lack of space slightly away from it .
