The only blinking orange light is located on the Network RJ45 connection

If you're talking about the Power light on the Front panel:

If the Power light is blinking green the computer is in a sleep state: The computer is in standby mode. Press a key on the keyboard, move the mouse, or press the power button to resume normal operation.

If the Power light is blinking amber indicates that an internal power problem might exist; The computer is receiving electrical
power, but an internal power problem may exist.
Ensure that the voltage selection switch is set to match the AC power at your location (if applicable).
Ensure that all components and cables are properly installed and securely connected to the system board.

SOURCE: Heatsink for Dell Precision T5400

Actually what you need is a Heatsink & Fan for a Intel "Xeon" Processor. I believe some of these came with dual core and quad core CPU's. So make sure as to EXACTLY what type processor you have and look for a heatsink for that.

Or, you can call Dell directly and purchase it from them. Dell sometimes uses Fan tunnels in there machines, instead of directly mounting the fan on the CPU.

I hope this info helps, please rate my solution. Have a great day!

Dell desktop won't power on, orange light blinking


Try removing the battery for a few seconds and putting it back in again.
If that doesn't work. It could either be that the battery is flat, or the battery is not an offical Dell battery.

Solid orange light on my vostro 200


If your fans come on full blast then you have a bad motherboard. If the amber light blinks, you have a bad power supply.

My pc is not turning on (all the light does is blink orange)


Woops -the blinking amber light of doom is a common fault on dells -
usually a solid amber is the Power supply while a blinking one indicates Motherboard problems. If machine is still under warranty dell will replace it.
If not then it will cost you to have them replaced.
