Well you can either buy a replacement button that will just connect to your motherboard easily. Or you can cut the wires to the button and connect them with electrical tape. But by doing that it will stay on, and I don\'t know how safe that is. Also you could cut the wires off and connect them to a switch or button that you can buy at a car shop like advanced auto parts or something. Just be careful make sure your computer is unplugged and use the same caution as you would with any electrical stuff.
Although its possible that the on/off button is physically damaged, chances are greater that you have a power problem on your PC motherboard. The simplest way to determine which of the two is true is to open the case up, look for the wire which runs from the on/off switch and see where it connects to the motherboard. Once you have located this connection unplug the switch wires and, with a small screwdriver, short out the 2 pins where the on/off switch wires were connected. Your PC should turn on. If not, you need to message me again in order for me to assist you further in diagnosing the problem. Best wishes, Graemevm
Hi Raul, Try this following instruction to isolate the problem. 1. Check the power outlet/AVR if it has an output, if okay, 2. Check the wire if okay, often times, the wire is damage or open. try to use another cable. 3. If the wire is okay, try to isolate the power supply, remove the power supply connection to the board and short the color gray and green wire to see if the power supply is working, if the power supply turned on then its ok. 4. It the power supply is working, try to check the power on button, it might have a problem. to override the power on button you can short the pins inside the board where the wire from power button is connected to motherboard.
The power button connects onto the motherboard with a jumper. One end of those cables probably go to the button the other end should connect to the motherboard where it says pwr with a few little pins.
The most common reasons for this are:
1. Switch failure (the button is broken)
2. Power Supply not working
If you can go inside the case of your PC (if confident that you won't mess up with any other thing).
First of all remove all power cords (even the monitor's wire)
open up your case again if confident but its better if you get it checked by a technician.
By the way to check the switch the method is given below (i expect that you have a reset button)
There must be a wire on which PWR would be written it will be directly connected to the mother board. To get to it look for the button inside the case and follow the wire, when you find the wire carefully take it out and carefully search for the wire of the reset button and connect the reset wire in the place where the power wire was connected.
Plug in all the wires back again cautiously and then press the reset button and check whether now it turns on or not.
If the above method works it means you have a faulty power button and if not then you have either a power supply problem or
In some extreme cases the mother board can be burnt.
I suggest that you will open the cpu and look for wire that will connect from the restart button to the motherboard. If you have set up manual of the mother board, just follow color code of the wire that will be plugged in to motherboard. ASUS and other motherboards have connection of the wires located below the circuit board just in line with the tiny colored wires entwined by pairs.
The motherboard in your computer is an MSI MS-7145, which is also called RS480M. You can download a copy of the manual here. The front panel connections are on page 2-20.
Looking at the header JFP1, pins 1 through 9 (odd numbers) are the front row, pins 2 through 10 are the back. Pin 10 is the missing pin. The power switch connects to pins 6 and 8. The power LED connects to pins 2 and 4. The HDD LED connects to pins 1 and 3. The reset button, if used, connects to pins 5 and 7.
If you know where the two connection came from then You can solder it vice versa because can be connected either. That is reversible connection as long as connected parallel from the motherboard. there is no problem with that just connect onto post1wireblack, post2redwire.
