Razer DeathAdder on and off help!

Sounds like a disconnect/short in the usb cord. I had the same thing happen to my mx300, and it eventually stopped working completely. Does wiggling the wire or holding it in place fix it temporarily? You can fix it by finding the problem area (usually where the cord leaves the mouse), cutting it out and splicing the two sides back together.

It's not too hard, I ended up repairing it in about 30 mins(works perfectly now), and I had very little soldering experience. It'll cost about $15-$30 for all the materials (soldering iron, solder, electrical tape). If you decide to do it and need advice, I can post more info.

Yea that doesn't always fix it, but I'd say they problem is definitely the cord. So you have two options, either buy a new mouse since you can't RMA it, or try and fix it yourself, and gain some useful soldering experience in the process.

I'd definitely recommend that you google "how to solder" and watch a few tutorials on it. It's not overly complicated, and the videos are all fairly short, but there a few things that you should know.

Then buy a soldering iron, solder, a wire stripper, and electrical tape.

Look at the picture below. See the blue circle? That's most likely where the problem is, so what you'd have to do is cut the cord where you see the blue lines. Then take some scissors or a knife, and carefully make a nick in the outer insulation so that you can peel it off to reveal the 5 individual wires inside(the white,green,red,and 2xblack that you can see going into the white socket). Only peel it back about an inch or so.


Do this for both ends. Then take your wire stripper and strip each of those 5 smaller wires back, for both ends again. If you've never used a wire stripper before, watch a quick tutorial. After you strip off this inner insulation, you'll see a bunch of tiny copper wires all bunched together. Twist each one a little bit so it doesn't fray everywhere.

Now all you have to do is twist the matching sides together http://www.advrider.com/forums/showthread.php?t=281500, solder and then wrap the soldered joints in electrical tape so that they don't touch. You could actually skip the soldering if you wanted, and just use electrical tape, but the strength of the splice would be pretty weak.

Then you'll likely have to push the soldered cord in further than it would be normally, so that the spliced portion is inside the mouse, not hanging near the opening. You may also have to find superglue the opening or something, as it seems to be rather big normally, with the bulky plastic portion (that you would have cut off). Or maybe not since there might be an L-shaped indention in the bottom half that holds the cord in place, like in the Mx300 I fixed. Hard to tell from the pic.

Hope that made sense.

Like I said I've never opened one before, but many people have. Are you sure you found all the screws? You need to remove the feet first.
