Dimension 5150 will not power up.

Hi Billy,

Welcome to the Community.

Do you not see any light at the front or even at the back of the system?

Did you try a different power supply?

Also, let me know if you get any of the diagnostic indicators mentioned below:

LED pattern	Code Translation
	System POST complete – LED timeout has occurred
	BIOS Checksum Failure – Recovery Mode
	CPU configuration activity or failure
	Memory subsystem configuration activity or failure
	PCI device configuration or failure
	Video subsystem configuration or failure
	Storage device configuration or failure
	USB subsystem configuration activity or failure
	No memory detected
	Fatal system board failure detected
	Memory detected, configuration or compatibility error
	System activity preceding video initialization
	System resource configuration
	Reserved
	POST complete – Onscreen error message
	POST complete – OS handoff complete

Thanks & Regards

Hi Manshu S,

There is a blinking light at the off-on switch and a greenlight on the motherboard near the ATX power input.

How will I see the diagnostic indicators as I have no diagnostic equipment.

BTW - Since posting I was told to use a paperclip alongside  the green and black wires of the ATX Main Power cable and the fan/power startsup when I  do this. .

Hi Billy,

Let me know the color of the power led as well.

You don't need any diagnostic equipment to see diagnostic indicators. Please refer to the picture below to know where the diagnostic lights are:

 

Also, please check if you have replaced the system board correctly. You may refer to the manual below:

NOTE: System board replacement is advised to be done by a professional only.

Dimension 5150 would not power up so purchased/installed a new motherboard. Will still not power -up. Any thoughts/ideas??

Have you replaced the power supply? If not and your 5150 still has its original power supply, I suggest a new one.

This is a good budget choice that is superior in quality to the OEM unit.
