My lap top has power. I've tested the board with a voltmeter. THe lights come on, but no fan action, no disk, no go. There was no warning, it just stopped one day. The lights on the front change as usual like it is going to crank up, but never does.

Not trying to be condesending but start simple and work your way up.
1. strip dow board to;
a. known good older processor
b. known good single memory stick
c. known good power supply
move memory one slot over
Move memory over one slot
move memory to last slot
You have tested the variables if still not working you have a bad mother board.
contact foxconn for replacement.
1) The bracket is a simple push fit one - it just pops in and locks in there when pushed.
2) Simple test (assuming that the processor , video card and the memory have been tested in another motherboard and are good): remove all the disks and try to start it up into the BIOS - if you can't then the problem is in the motherboard. As a last hope reset the BIOS and remove the battery for one hour. If it doesn't starts even after that then the board is dead. The DVD burner will power up and seek even if it's not connected to anything else - all that it says is that the unit is working normally.
Good day sir, let try to test first the power supply, Unplug the power cord, remove the 20 pin (24 pin for the late model) molex power connector from the motherboard, plug in the power cord, get a 2 to 4 inch jumper wire, short the green wire with any of the red or black wire on the molex 20 pin power plug, the result maybe the following:
you will see the power supply fan turn. you power supply is in good order. replug the power supply, and test again.
you will see the fan turn for a few second then stops. you power supply is selective, and may require a different type of motherboard. Get a new one.
you wont see the fan turn at all. get a new one.
If in case you are with #1. uinplug the power cord and remove all the expansion cards, data cables from the hard disk and cd drives. we are trying to isolate the problem. make sure that the only connected cables on the motherboard are as follows:
20 pin power cable.
4 pin 12 volt power cable (if applicable)
Test the pc once more. plug in the PC. If still the board wont power on. problem with your motherboard. Note:make sure your RAM is good. Hope this helps.
Try choosing the 'Exit Without Saving' option in the BIOS menu. If this kicks you to the boot media search, then 99.99% the BIOS is corupt. If not, try to replace the CPU cooler (don't forget to apply the thermal grease).
check the back of the power connector to see if it is loose. I have known alot of situations were, if not carefully removed, that power connector in the can free itself from the sodder on the Mother board therefore you wont be able to charge the battery nor boot up. hope that helps
There must be a short between the board & case. All motherboard mounting screws should have red fiber washers. The bottom of the board should not be touching the case. The board should be mounted on stand-offs. These brass looking stand-offs screw into the back plate of the case & the board is screwed into these. If you feel the board is still touching the case. Cut a piece of paper and place it between the board & case. Memory not seated correctly or defective memory can also resulte in such problems. The red light on most Pc's is a hard drive light. If your PC have two dimms remove 1. Other cards not needed for this testing should be removed even sound cards. Connect only mouse & keyboard & monitor. It's all worth it if the pc works.
it could be your power switch, veriy that it isnt the power supply by
1.) un-plug it from the main board
2.) look at the main board connector(one coming of the power supply)
3.) you should see green wire and next to it a black one
4.) using a paper clip bridge the too wires
5.) if it works proceed to net step if not get a new power supply
to check case switch and board switch
1.) plug in power supply to main board
2.) look at the pins where the power button connects to
3.) using a metal object (blade screw driver) bridge the pins
if the board should start up>
then its your power button on the case that is bad, you can try to repair it, chage it or buy a new case,
if it doesnt work.
1.) ensure that jcms(jumper to flash the bios) is set correctly
2.) unjack each drive one at a time to see if any is causing stalling
3.) get a new main board
try removing the power plug at the back of your PC then the processor and memory for 10 sec. and then put it back...power on and observe...if you got same problem try to test each caps, fuse and transistor of the board probably around the proc.and mem. area...you might point out which piece to replace.I hope that would help you..
