I dont know if its only me but I have moved my computer to another location and when I turned it on everything worked out just fine but the power button LED doesn't light up and I hope there are no other issues but I was wondering if I can turn the LED up through the bios or is it just some wires that need reconnecting ? Also do you think any other components were affected except from the LED light ?

Page 23 (1-7 in your manual) shows the diagram for your board.

You're going to need to check the connections for header #12 (bottom right part of the board).

Page 52 (1-38 in your manual) shows the diagram for the header.
The one labeled PWRBTN is the pin for the power button. The two to the left of that light the power button.

Those can come unplugged easily when the case is moved. Check those and see if they're all connected correctly. If they are, report back and we'll see if we can figure out another option.


The plug that connects your power button LED to your motherboard is really tiny and it's usually only held in by friction. In other words, yours probably came unplugged.

If you let us know what kind of motherboard you have, I can tell you exactly where to look to see if it came unplugged. Otherwise, you can look in your case for a wire coming from the back of your power button. It will look like the one in this picture that says "POWER LED".

There will be a small header on your motherboard where that's plugged in. This picture will help you see what it looks like.

Yours may have a different layout than that. Sometimes the layout is printed on the motherboard while sometimes it can only be found in your manual.
