Question about Dell Dimension 4600 PC Desktop

1 Answer

Computer will not turn on

I push the button and nothing happens. I opened the case and the small green light on the motherboard is lit. No lights come on on the front of tower and no diagnostic lights come on on the back of the tower. I got out the multimeter and the first thing I checked was the button/switch. There is continuity when the on/off swithed is in the depressed position. I then unplugged the power supply from the motherboard. Power supply unit looked good with the green wire jumped to ground the fan came on and the voltages looked good at 3,5,12volts at the different colored wires. Is there anything else to check? Is it a bad motherboard?

    power supply switch in 115v position - ok

    front panel button passes continuity test if held in manually. If released no continuity.

    plug from switch to motherboard is in good.( is that what you mean by switch jumper?)



    Don't know if this helps? about a week or two before it died, when turning off computer, it would start shutdown but it could take anywhere from 5 to 15 minutes or more to completely shut down. you could hear it. The same type of sound like on startup.



    Power supply fan will only come on when disconnected from mobo when green wire jumped to grnd. rechecked all voltages -they are good.

May sound strange, but is the power supply switch in the correct position?
If the button is pressed, makes your continuity test, and not even the fans come on, check that the switch jumper has not come loose from the motherboard, and finally, if the motherboard is plugged in and no fan comes on when you push the power button, there may be chipset damage from an electrical surge or overheating.
In this case, a new mobo is your only option.

Green light on my power supply stays lit after unplugging


Usually the light will time out after the capacitor has drained. Your machine is getting a bit old , your PSU may be the problem. If you plug it in and push the on/off button and it blinks, fans spin and shuts down, it's most likely the PSU. Look for a in-line fuse on the Motherboard, if blown, replace. Look at the motherboard closely for damaged components, capacitors, etc.

No power to my desktop computer HP A1330N and no green light in the back of the power supply


You replaced power supply and your made sure you plugged everything back into the motherboard snuggly and in it's proper place? If so it might be your motherboard is bad.

Make sure you have the new power supply turned on. Sometimes there's a O/I switch on the back of the power supply. Flip it and try to boot and see what happens. You might have another bad power supply.
If so your motherboard might be burning them out.

Try removing the power cord for 30 seconds and press and hold the power button. After 30 seconds put the power cord back in and press the power button to see what happens.

Do your fans work when you press the power button? Do you hear any fans running?

Your computer power button may not be working, or the CPU may be bad and it can also be the motherboard is faulty.You need a new case or fix the power button or try another CPU in the computer or replace the motherboard.

Getting power but wont boot up or anything


pull out everything in the computer except what's required to boot...so any pci cards or video cards (if you have onboard video). you can also try pulling out the ram (while unpowered AND unplugged) and then booting to hear beeps...if you pull the ram out and the computer doesnt make a sound, its probably a bad motherboard and needs to be replaced. if you hear beeps, try replacing the ram or disconnecting other parts...like harddrives, optical drives, modems and what not.

Gateway 500xl pc will not turn on power button is lit up yellow


A LOT of Gateway computers will go into this catatonic state because of a dead battery. The battery is on the motherboard -- it looks like a metal disk about 1" in diamter. Check it or replace it. This applies to laptops too (not the actual laptop battery, the CMOS battery -- a laptop will have one on the motherboard too)

Hope this helps

GT5014 won't boot


Generally this means there is a problem with the power suppy as it is not giving a correct voltage to the motherboard to start the computer. check your fans on the power supply, make sure they start when you try to start the computer . A power suppy may be purchased and installed fairly easy. and you should spend no more than 50 dollars on the parts.

Computer will not turn on at all. Dell Dimension 5100 desktop


I would unplug the power supply from the motherboard, wait a little while and then plug it back in.
Try to power everything back up and it should come up.

I am assuming you are getting a light on the motherboard that indicates power is being supplied?

Dell e510 won't make it to post


Unplug computer, disconnect all usb/monitor/internet, open it, hold power button until green led on the inside on the motherboard turns off, pop out the BIOS battery (looks like a big watch battery and use a small flathead screwdriver to depress the spring lock on one side), plug in computer, hold power button for about 20 seconds (must reset BIOS), let up on power button, wait 10 seconds and push power button. The computer should turn on. Wait for it until activity seems stable (1 min. or so). Push powerbutton to shut off.

If this has worked you have proven that it's not the power supply (it turned on). If you purchased a non dell power supply, you might try this with the original one installed.

Go buy a new battery (CR2032 3 volt). Unplug computer, open it, hold power button until green led on the inside on the motherboard turns off, pop in new battery, plug in (you should notice the power button blinking amber again), hold power button until it stops blinking (about 20 sec....again must reset BIOS), wait 10 sec., push power button. the computer should turn on. Wait for it until activity seems stabe (1 min. or so). Push powerbutton to shut off.

Now, close case, plug in all usb/monitor/internet/etc. Power up computer. You'll get an internal floppy drive error. Push F2 (maybe F1) to get into the BIOS settings and go to "drives" and turn off the internal floppy. Save and exit. The computer should boot properly now.

This seems to be a big problem with the e510, my theory is that this one small battery is the root of most of these failures (as these computers usually fail after 1-2 years), not the power supply or the motherboard (heck, when you replace the motherboard it comes with a new one of these batteries...a several hundred dollar piece of hardware, with a $5 battery that will actually fix it).
