Hope this will help you

Hi careyfraser,




1. There are 8 wires from the front panel's casing, excluding USB connectors and front audio cable.

2. Just plug the front panel switch headers to the F_Panel main board connectors. 1 & 2 are positive, if the led do not light change polarity but Im sure it will.

Note:The mainboard provides a front panel connector for electrical connection to the front panel switches and LEDs. JFP1 is compliant with Intel® Front Panel I/O Connectivity Design Guide.


Hopefully this information helps.

Thank you for using FixYa.

I would double check the connections to the main board. Some power supplies have two power connectors to the mother board, a 20 pin connector and a 4 pin connector. Sometimes the four pin connector is in a different location from the 20 pin on the board. Make sure both connectors a plugged in.

Make sure the connector for the power switch is plugged into the board. Dell's usually have all the wires for the front pane in one connector.

You should also unplug everything from the board except the power supply and front panel. There could be a hard device causing the board to hang up.

I have had power supplies die and short the main board. I hope that isn't the case here.

The actual Processor fan connects to the CPU Fan header on the mainboard. It's 4 small pins. It plugs in right near the CPU socket on the mainboard. Check the user manual for exact placement, you may download it from the AOpen website if you don't have one already.

Plug in the 20Pin connector if that is the most Pins that the mainboard will allow. Cable tie the other 4Pins back onto the 20Pin connector.

Then if there is additional 4Pin connector required by the mainboard for CPU power and you don't have that connector on you power supply, you will need to purchase a Molex to 4Pin CPU power connector. When you go to the computer store check with them that all is correctly connected.

Take care!

Thank you, you are most kind.

I would wish that you would take a moment, and join FixYa. It is free to join, and we'd love to have you on board.

Hi res0m9hv,

HERE's the maintenace manual that lists all the p/n on the board.

Good Luck

measuring 12v at the psu is not enough. the psu have several voltage outputs ranging from 12volts to 3.3 volts and maybe even 2.2 volts.. firstly, check all onboard USB ports, a bent or shorted pin in a USB port will prevent the psu from operating. next, the psu has a safety connection to the mainboard, this is called the power good signal ( pwrgd) and it is a signal from the psu to the mainboard and tells the mainboard that everything in the psu is functioning correctly. If the powergood signal is lost ( drops from 5volts to zero volts) the mainboard will issue an interuppt to the cpu and the cpu will shut down, this will also shut the board down to prevent damage and data loss. mainboards all use pretty much the same connectors so your board will have either a 20 pin power connector or a 24 pin one. It may also have an additional 4 pin connector to power the cpu and northbridge functions. use a known good psu and plug this into your board along with the 4 pin connector and attempt a switch on. If the system begins to boot, replace the psu. if not, try unplugging or removing everything connected to the board, pay special attention to expansion cards and usb ports. remove the ram sticks and video cards if fitted, then attempt to boot again. if the system does not respond, replace the main board. if it now begins to boot, refit everything one item at a time and try starting the machine. turn off before refitting the next item and start the machine up again. when you get to the problem item, the machine will stop starting. If all else fails, replace the mainboard or take the machine to a reputable repairer..

Sorry in the 1st instance for my lack of specific knowledge when it comes to ACER hardware.

Is the model of your MOTHERBOARD - Acer m464?

If so do you happen to still have a manual that came with the motherboard?

Sometimes you can see the pinout in white writing on the mainboard itself near the connector block... have a close look and see if it is there.

The pin out for the connector block will definately be in the mainboard manual. If you don't have the manual then you'll need to do a little searching for it... I'm sure a .pdf of it will be floating around... i guess start at the ACER site.

On the rack mount chassis, are the plastic chassis connectors grouped (ie. 2 wires into 1 connecter for pwr led, etc) or are they individual single pin connectors?

Either way for each group, one should have a little TRIANGLE on the opposing side to the writing. Conventionally this is your positive (+) pin when looking at the pinout diagram. Ensure you have correct polarity for all ur connections obviously.

See how you go mate.
