My 873 n will not turn on


if you are refering to a computer

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your "((MOTHERBOARD TO YOUR HARD DRIVE))" make sure they have a secure connection and are not faulty or just replace them they could be faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error even something as small as a faulty electrical extension or fan lead can cause this problem

follow the troubleshooting procedure a computer needs all of the data and electrical current to travel through every device and to have an end to be able work properly

a motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail check all electrical extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working also it could be a dirty computer clean all of the dust from your computer you could use a vacuum cleaner but whatever you use make absolutely sure there is no moisture gets to anything in your computer and before you touch anything be sure to wear an earth strap hope this helps

Computer will not turn on....how do I check to see if power supply is faulty? I have power supply removed and have a tester to check for dc voltage etc


I just went through a heap of troubleshooting with power supply issues before swapping psu's and finding this was the solution to my problem. Had a closer look at my psu that was faulty, the green light was flashing on the psu, unplugged all components and thought that I now had a non-flashing green light on my psu, on closer inspection the light was actually flashing very fast so appeared to be an almost solid light...the psu was stuffed so replaced it and no more issues. If your power supply has a green light check to see if it is flashing when plugged into voltage with nothing connected to it. If it is a solid light then it is probably ok.

Hi

Thank you for your query

It would seem you have a possible DCf jack problem, causing the mentioned issues

If the DC jack is faulty it can cause the problems mentioned above.

I would recommend that you book the laptop into a reputable PC shop for them to replace it

I hope this has been useful

Protection light blinks and beeping


it has been through an overload (hence the protection light) and needs its breaker to be reset (look for a poped out button and push it back in) or it needs a new fuse (replace ONLY WITH THE EXACT SAME MODEL OF FUSE or it will either blow too early or too late (or not at all) when there is a surge.

I have an IBM 74P4410 power supply on which the DC led does not light up. There is no signs of damaged or heat stressed components. Any idea?


To make sure that your PC is working, try to check the CPU Fan is working. If not then no power supply going through into your Motherboard. At this case see to it that you connect properly your power supply into your motherboard and with all the power buttons are correctly connect. Look at it inside your CPU ok! then tell us what is next problem on your unit.

Push button small light in middle comes on fan on power pack turns 1/4 turn and that is it


i have this problem with my E Machines W 3104 and i unplugged it and still i could make the fans turn on like you said for maybe a quarter turn, plus the lights would basically flash once every time i pressed the power button. after the little death beep noise from inside when it loses power completely i plug it in again and it will turn on just fine . the first time it did that i thought it was because it had too much power built up in the power supply, and maybe it did but it ussually turns right back on after "draining it". try that and see if it helps at all

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!
