Sounds like you only have power going to your motherboard.

The power supply might be bad on it, that or maybe the power cord is going bad and is only letting a small amount go through. I don't see why there should be a problem if you have even a little bit of power going though.

Optiplex 755 blinking amber light, simple solution, I'm no IT professional.


If the power light is blinking amber, the computer is receiving electrical power, but an internal power problem might exist.A power supply or system board failure has occurred. Try to isolate the problem by removing or disconnecting all cards, i.e. video, sound cards and disconnecting CD/DVD and hard drives.

OptiPlex 755 flashing orange light only


An Amber blinking power button indicates a low voltage problem. This can be caused by a defective power supply or a defective motherboard. Since you replaced the power supply, my guess is that the motherboard has a problem.
Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

Optiplex 755 showing orange colour light on power button.. how can i fix this problem


A Blinking Amber or Yellow power button means that the power supply is receiving power from the source but is unable to properly distribute it to the components. This can be caused by a defective power supply or a defective motherboard. Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

I got dell optiplex 755 desktop computer in the power supply unit at the back there is a small button and a green light what are these for??


It help diagnose problems with your computer

A solid green light means the computer is operating normally.

A solid yellow:- the power is operating fine but your computer not processing data. This could mean there is a problem with the CPU or another component on the motherboard.

A blinking yellow light: power supply is receiving power from the wall, but not functioning properly. This generally means the power supply itself is bad and should be tested or replaced.

A blinking green light means the computer is in standby mode

I recently worked with a couple of used Dell desktops that someone got from work. Sound familiar? I couldn't get them to come on because the plastic bracket that holds down the CPU heatsink was broken. The heatsink was also covered with a carpet of dust. The new owner could've bought a new heatsink/bracket online, but they declined to spend money. Open it up, make sure everything is in order to diagnose the problem.
