Power led is connected wrong..need manual for

1. Identify the headers: Locate the front panel headers on the new case and on the motherboard. Make sure that you have identified the correct headers and that they are compatible with each other.
2. Check the pinout: Refer to the manual for the new case to determine the pinout for the front panel headers. Make sure that it matches the pinout listed for the motherboard, as mentioned above.
3. Connect the wires: Use the pinout information to connect the wires from the new case to the appropriate pins on the motherboard. Make sure that each wire is securely connected and that there are no loose wires that could cause a short circuit.
4. Connect the HDD LED: The HDD LED can be connected to pins 13 and 14 of the front header (LEDH1).
5. Connect the power LED: The power LED can be connected to pins 3 and 4 of the front header (LEDH1).
6. Connect the reset switch: The reset switch can be connected to pins 7 and 8 of the front header (LEDH1).
7. Connect the power switch: The power switch can be connected to pins 10 and 11 of the front header (LEDH1).

Make sure that you connect the wires correctly and securely, as an incorrect connection can cause damage to the motherboard or the front panel components.

You will need the user's manual for your machine to make sure that you are hooking the wires up correctly. However, most motherboards label these connections directly on the motherboard next to their pins.
Look for an area on the mother motherboard with two rows of six to eight pins. Next to them you should labels such as PWR_SW (power switch), RST_SW (reset switch), HDD_LED, PWR_LED, etc. You won't mess anything up connecting something to the wrong pins, but it isn't that hard to figure out as the wires are usually labeled in the same manner as the pins. So HDD_LED would plug into the HDD_LED pins, PWR_SW to PWR_SW, etc.

Connect the front panel leads to the motherboard connector marked "JFP1" using the following pins as indicated by the markings on the motherboard and the front panel leads: HDD LED on Pins 1 and 3; power LED on Pins 2 and 4; reset switch on Pins 5 and 7; and the power switch on Pins 6 and 8.

Good luck.

Printed on the MB
HD LED +1 -3
PWR LED +2 -4
RESET 5- 7+ (Why the changed order? & there's no reset button on this computer.)
PWR ON +6 -8

There are nine pins with a little triangle pointing at one and a 2 next to another.
The pins on the MB look like this:

Found some info on the 506GR. Unfortunately Gateway is keeping the service manual a big secret.

This will help. Thanks please keep updated. please do rate the solution positively .Thank you for using Fixya

If you no longer have the manual for you're Intel D815EEA motherboard, open the link provided and download it; http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=17793&ProdId=385&lang=eng
You will also need Adobe reader installed to view the manual; http://www.adobe.com/products/reader/
Read over pages 65 to 68.
Once completed turn to page 68 Figure 23. Front Panel connectors. Figure 23 shows two views.
View - (left figure), shows J9C1 as you look down at the front panel pins. The right figure will not be needed. Connect each jumper or each pair as shown.
Wire colors are important and do vary from case to case. The common color of each pair will most likely be used for negative. Wire colors such as blue, light blue, green, light green, red and light red are commonly used as positive.
Pin 1 will be positive and pin 3 will be negative. This is letter - C. Hard drive activity LED.
Pin 2 is positive and pin 4 is negative. Case power LED, and so forth.
As mentioned on page 65, the case front panel pins use 5 volts DC. If you make a mistake and place a jumper backwards (No LED light), just power off the switch on the back of the power supply and correct the jumper by turning it 180 deg. If you’re case’s LEDs do not light up than you will need to connect letter G and letter H. The electronic circuits under the motherboard should supply all 16 motherboard pins with the 5 volt DC and ground needed.

The manual for your computer is available from emachines, p.168 shows the info you need (replacing the front I/O panel)

The good news is that you can't harm the computer by connecting the wires wrong and the bad news is they just won't work the way they are supposed too if not connected properly. The LED's must have the correct polarity to work.
In general, if you look real close (as in magnifying glass and flash light) you will see the ID for each set of pins is printed on the motherboard (pwr,rst,HDD,pwr sw,speaker) Just match what it says on the motherboard to what it says on the wires. Don't worry if you get the polarity wrong. If a light doesn't work just swap the two wires. The colored wires should be positve (+), though. The reset (rst) and power switch (pwr sw) wires don't require polarity.
These instructions are for most computers in general, YMMV.

Try shorting the power pins on the Motherborad. (establish contact manual. use screw drivers such that they touch both the pins). The power pins are the one the Start button are connected to. Remove this connection alone. If this powers up the system, you would have to get the Button replaced. Else there's something wrong with the motherboard. Kindly get back for any clarifcation.

Pin arrangment is Industry Standard Architecture.....

pwr led pwr sw N/C
X X X X O

X X X X O

hdd rst N/C

translated this is top row left to right ...... power led, power switch no connection

Bottom row is left to right........ hard drive, reset, no connection

Note: not all computer cases have a reset button, also the connectors for power led and hard drive produce a light, if the light does not show, power off the pc swithc the cable rooun 180deg on the connector pins and reconnect.

Hi sjcrofts,
The most common problem for most people is knowing what wire color is positive & which wire color is negative. The colors blue, red, green, light blue, light red & light green are normally positive. The color white & black are negative. Your board uses only 2-pin connectors. The 3-pin power connector can be turned into a 2-pin connector to work with the M848ALU pins.
(Page 13, PANEL1). How to? Take the three pin connector, on the back side of the connector you'll see a small tab that holds the wire into the connector. Use a needle & pull tab up while pulling the wire out at the same time. The wire should slide out. Insert the wire back into the connector next to the other wire. You do not need to hook up the SUS led which stands for suspend.



Pin 1 is positive & the manual shows this by adding the _P = positive.
Pin 3 which is to the right of pin 1, is negative for the hard drive led. Pins 9 & 10 are not used.

Good luck sjcrofts!

Usually indications are printed beside proper connection Pins . Find your model number and posta comment to look for your motherboard data sheet on web.
