Vaio desktop blinking power supply


Remove the side pane to access your motherboard cables, etc. Locate the connector on your motherboard that contains the wires going from your power supply to your motherboard. It will be a large, rectangular connector with a lot of individual wires It is not a ribbon cable but should be located next to a ribbon cable connector and next to a green blinking light on your motherboard (when the power supply is plugged into the wall). Note: This green blinking light is in addition to the green blinking light on the back of the PC.

This next step is important: You have to disconnect the connector noted above from the motherboard WHILE the power suply is plugged into the wall. Wait a few seconds and plug it back in. The blinking reen light on the motherboard should now be a solid green light. The PC should now power up.

If the steps above don't work you will need to get a new power supply.

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?

Hello,

If the outlet is good and the cord is good, you may have indeed blown the fuse in the power supply. That is the only fuse. The fuse in the power supply is usually "hard-wired". Not necessarily, but usually. You would need someone familiar with them to replace it if it is blown.

Some computers have a green LED on the back of the computer near the power cord. Do you have one? Is it on? You can also look to see if the small green LED is on on the motherboard.

If you get no indication of power, the power supply is probably gone. A new on is about $25 and pretty simple to replace.

Hope this helps.

Thanks for using Fixya.

Removed power cord from back of pc and after plugging it back in I suddenly had no power. Replaced original power supply (Bestec 300 W 24 pin main connector) with a new Dynex 400W 20+4 pin and still...


Before calling it quits on the motherboard, try disconnecting ALL non-essential devices from the motherboard.

This includes drive cables, all slot mounted cards, etc.

Leave the processor and ram in place. Make sure ALL power cords from the power supply to the motherboard are properly plugged in. Some power supplies have 2 cords to the motherboard, a large plug and possibly a separate 4 pin that plugs in near the CPU. After checking your plugs, see if the board will power up. If so, you should get some beeps or status lights. If not, then it is likely the board has failed. Since you have replaced the original power supply, (assuming the replacement is compatible), it is not likely you have 2 bad power supplies.

If the board DOES power up, then plug in 1 internal device at a time to determine what might be "killing" the boot. A bad hard drive or DVD/CD drive can cause this as well as a shorted USB or firewire device.

Green light flashing on back of unit near power cord also green light flashing on motherboard near power supply plug in.


I would suggest trying to replace the power supply. If that does not fix the issue, i would need to hear more about the computer.

Blinking green light front and back. Clicking sound from inside.


Do you mean the little green LED light near where you plug the power cable into the back of the computer? If that's the blinking light then unfortunately, this means that power is getting to the power supply but it is not going from the Power Supply to the Motherboard/Devices. The power supply is broken and is not converting the power from the wall to the proper voltage for the Motherboard/Devices. You will have to replace the power supply.

Call HP, and I hope you are in warranty and get it replaced for free or you can order the exact same one from HP that originally comes with that model. 1-800-HP-INVENT for their tech support line.

it sounds like the hardrive you installed overloaded the system and cause a low power operation on the computer the motherboard may be bad because of this as well as anyparts that were connected to it i have had this happen to me before and well i know it sucks but your best bet is to just buy a new computer and make sure you power supply can handle extra 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).
