I have a dell dimension E521 and it no longer powers up. When turned on rather than booting it up the light just flashes orange. The advanced troubleshooting says # If the power light is blinking amber,...


You are correct. According to the Power LED it diagnoses this as:
The power supply is receiving power from the source but is unable to properly distribute it to the components. Reseat all power connections to the system board.
It's either the power supply or the motherboard. Power supplies run anywhere from 50 to 100 dollars. Motherboards for the Dell can run anywhere from 200 to 300 dollars plus labor. Also check your USB ports to see if any are damaged. They can short out your power supply if broken.

My power led connector (green,white) power sw connector (black,white) got out of place and i dont where they go


The eMachines T3302 desktop computer, uses an FIC K8M-800M motherboard.
(First international Computer, Inc.)

Where those wires go on the motherboard, is termed a Front panel header.

The Front Panel is the plastic front bezel of your computer.
(Where the Power On button is, Power On LED light, and so on)

Looking at the motherboard with the Processor to the Top, Ram Memory slots to the Right, the Front Panel header is at the bottom right corner, and over to the left.

Look at the jumper block in the bottom right corner. Right in the corner.
This is the LED type selector, jumper block.
Has 6 pins.
3 across the Top, 3 across the Bottom.

(This jumper block is to set whether you are using a Power On LED light, that has Dual Colors, or a Single color.
The default setting of the jumper on the block, is set to use a Dual Color LED light, for the Power On LED)

Move to the left of this jumper block. The Front Panel header is to the left of this jumper block.

(FIC terms it a Front Panel Block Connector)

It should be White in color.
Is right against the bottom edge of the motherboard. (Parallel to the outside edge of the motherboard)

Has two rows of pins sticking up.
5 across the Top.
4 across the Bottom.

The pins are numbered from the Right, going towards the Left.

(From the Power On LED jumper block, towards the Front Panel header)

On the Top row going from Right, towards the Left,
Pins 1 ,3, 5, 7, and 9.

On the Bottom row going from the Right, towards the Left,
Pins 2, 4, 6, and 8.

A) Pins 1 and 3 are for the Power On LED light.
Pin 1 is for the Positive ( + ) wire.
(Green)

B) Pins 5 and 7 are for the Power On switch.
Pin 5 is for the Positive ( + ) wire.
(Black)

[Although it really doesn't matter which way the wires go. It's a SWITCH]

C) Pins 2 and 4 are for the HarDDrive activity LED.
Pin 2 is for the Positive wire ( + )

D) Pins 6 and 8 are for the Reset switch.
(IF used)

If any of your LED lights are dim, after attaching the Positive wire for each LED, it's because the Positive wire is on the wrong pin.
Switch the wires around

Packard Bell Easynote - not powering up


If this is a notebook , hold the power button down for about 6 seconds to make sure this is not just in hibernate. Make sure it is plugged directly into the wall power outlet , not a power strip.
Some laptops have a power increase when plugged into the wall and less when running off batteries.
