Question about Dell OptiPlex GX260 PC Desktop

Optiplex 560 Power Intermittent

Hi,
We have a Dell Optiplex GX560 that is used only occasionally. This is the only Optiplex GX560 we have in house. When trying to power it up recently, it wouldn't power. We did see a yellow light lit, on the motherboard.
After trying to locate a substitute power supply (and failing to locate one), our tech tried resetting some of the cable connections between the motherboard, the power switch, and the power supply. The system powered up, then later wouldn't power up, then did.
Any recommendations on where we might find a replacement skin (power supply, case, motherboard)? I realize this is an old unit, but it's used to build images for our DR site.
Thanks!

IN dell optiplex sx280 model system we are using in this amber power led blinking continuly yellow color because of this not able to boot the system. kindly give the solution for the same


Hi there!

A blinking amber/orange light on the power button of your Dell Optiplex means a hardware failure. If you know how to strip down your computer to basic component, then I suggest you turn on with only the motherboard, processor, memory and PSU. If you are not familiar with this, I suggest you bring the computer to a qualified technician.

Hope this helps

My Dell Optiplex 330 does not turn on,there is a yellow led light blinking


Hi,
If the power light is blinking amber, the computer is receiving electrical power, but an internal power problem might occur.

Ensure that the voltage selection switch is set to match the AC power at your location, if applicable.

Ensure that the processor power cable is securely connected to the system board.

My dell sx270 optiplex doesnt powerup somtimes after i unplug power supply


Chances are it's going to be slightly oxidized contacts on a supply part, but it's not broken, just intermittent. Some power supplies use relays to supply the voltage, and their contacts can get oxidized. The fix for this is to take it off it's mounting, open it up, and use paper or a very fine emery cloth to clean the contacts. You can also change the relay, if that doesn't work out. It's not something that will hurt your computer, just a nuisance.

Hi my power in my house went out today. When I got home my computer is off, no lights no nothing. Help


Hi there,

Check if the power cable was properly plug into the power outlet.

If you are using a AVR, or a voltage regulator, double check if the unit fuse was not busted. Due to some power outage and any abnormal power input on your area, the fuse will be the to down cause this parts will be the one absorb the power failure and not directly to the appliance.

Let me hear from you here again.

Thanks
