Re: Gateway power supply

Switching unit in powersupply sounds shot, if you want to test primary switching, un plug power from back, take main motherboard power socket off the board, take a paper clip and put it in the GREEN wire in the socket, and any BLACK wire, now (without touching the socket or having it touch anything else) plug power into the PSU, if the fans all fire up and spin, then the switching is fine, i would look at a fault on the board

Nothing happens when ON button is pressed, only green light on power supply is on. The fan is not running either. Preceeding this event, computer will run only whe I kept ON button for several seconds.

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 hope this helps

Gateway yellow power button, nothing starts, no fan, nothing. opened up computer and see mobo led light is lit. newton ps has a test button. tried to test with various components plugged in and the test...

Power supply has several voltages. Just because the 5v power is active doesn't mean all the voltages are OK. You need to have the power supply tested for 12v and 3.3v. A quick test is to unplug all the wires from the power supply. There is a single green wire on the motherboard main plug. Connect (use a bent paper clip) that green switch wire and any black wire. Plug in the power supply and it should run (fan starts)

Tower problems

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

Bestec atx-250-12z rev d hp model 5187-1098 pc will not start up when pushing button on front of machine green led on back of p/s flashes with power cord plugged in. does this indicate a p/s failure?

I have already replaced mant Bestec ATX-250-12E power supplies because they have an internal failure. Consider yourself lucky if the thing doesn't power up your computer because it has a problem of imposing the +12 volt line onto the +5 Volt line then blowing out the mother board. Sometimes you aren't so lucky because once the damage is done then it is to late to just simply replace that piece of junk. I was lucky with my daughters E-Machine because if she tried pressing the start switch on the front of her computer it would sometimes come on and sometimes not. She just mentioned this to me and I immediately replaced that Bostec ATX-250-12E before it could do any damage to her computer. If anyone has an older E-Machine or an older Gateway machine then it would be a good idea to see if it uses that Bostec-ATX-250- 12E. If it does then go order another power supply, anything but a Bostec, and instead of a 250 watt order a 300 watt or better. I hope that this has helped those that might have this problem before it destroyes *********** boards. Marty
