I never had green lights on my motherboard, they have always been red and it runs fine. the mother board was made with red led lights. if its not working right, it's probably the switches on the mother board, normally make the first switch on, and the other 3 off.

My xbox 360 had gotten the red ring, so I heated the mother board with a heat gun and then replace the thermal paste, now the power brick is orange/yellow when plugged in, turn on the box it goes green for...


We STRONGLY recommend you not to use heat gun as it can heat other components, when your system have 3 red light and no fan are spinning it means that one of your fuses has gotten damaged and no power can go through your GPU chip.
Thanks

WII DOES NOT TURN ON AT THE POWER BUTTON


remove the power cord from the wii. hold the power button in for 15 seconds.
plug the power back in. if the power light comes on check the color.
green is on, yellow is standby and red is totally off.

if there is a light press the power button and see if it turns on. if it does not then from a Wiimote, press and hold the power button on the remote. this should turn the console on. if the console does not turn on and the remote batteries are good you can try one more thing IF the light is on.

press and hold the reset button for 10 seconds on the system. disconnect power and replug. if you still cannot turn it on then your system is bricked or damaged and needs replacement.

in any case the power button is broken you can turn the console on and off from any remote

My printer will not turn on


First, try pressing and quickly releasing the Power button to start a Power On/Off cycle. Do not hold down the button. If this resolves the problem your done; if not continue on.

Inspect the power cord for visible damage; if damaged will need to contact HP to replace.

Disconnect the power supply (power module and cord) from the power source (wall socket) and the printer.

Test the power source, wall socket with or without your power bar or surge protector in place, with a small appliance you know works to confirm you have power. You may want to test the wall socket first and then test the power bar, etc. to make sure each component is not the problem.

If the appliance works then need to investigate the power supply. If the small appliance does not work you may need to check your electrical panel for a tripped breaker and possibly consult an electrician to check your electrical wiring.

To test the power supply plug in to the working power source; if the green light on the power supply does not light up you will need to contact HP to replace the power supply.

If the green light on the power supply lights up; reconnect to the printer.

Press and quickly release the Power button to turn the printer on. if the printer does not turn on you will need to check the USB cable.

Disconnect the USB cable from the printer.

Press the Power button to turn on the printer; if the printer turns on you will need to replace the USB cable.

If printer does not turn on, check the battery if your printer has one. A red light means the battery requires recharging; if it is still red after recharging, replace the battery.

If none of these steps resolve your issue before replacing the power supply try plugging the power supply directly in to a different working wall socket with no power bar or surge suppressor.; Press the power button.

If still no power to the printer you need to replace the power supply.

Will not power up. Green light on power source


Red battery light means battery is charging. It should start up even if battery is low. Try pressing on the area above and to the right of the power button, while you are pressing the actual power button.

Powering on


OK ... after a lot of trial and error, I got mine to work. I think it may be a really low charge or something. I had to press the power button until it was completely dark ... no flashing faint green or any colors. Then when I plugged it in, I got a solid red and left it for awhile. Then when I pressed the power button I got yellow, red and green ... the computer recognized it and then got a solid yellow.

Before when I had it plugged in, I'd get a lot of red random flashing ... and it just didn't seem to charge at all ... even after a full day.

I think the issue was that it was in this "flashing state (red when connected, very faint green when disconnected)" It wasn't easy to get it to turn off completely. Most of the presses of the power button didn't change the state at all. But if I got it just right, I could see the faint green light go off. That's when I plugged it in and got a solid red light, and eventually a good charge.

Hope this works for some others.
