Well BigAkita got to review this wonderful mouse, click here to view the review, and I guess I’m going to teach you how I modded mine.

**BEWARE! THIS WILL VOID YOUR MOUSES WARRANTY. NIETHER PIMPRIG.COM STAFF NOR I WOULD BE RESPONSIBLE FOR ANY DAMAGE DONE TO THE MOUSE, OR ANY HARDWARE. PROCEED AT YOUR OWN RISK.

This mod is pretty simple, but I saw a lot of questions asking what kind of LED to use, or how it works. Well guess what folks; today is your lucky day. Right now this mouse is probably the most expensive mouse out there, so trust me; I wouldn’t be doing this if it didn’t work.

We will start this modification with parts/tool list. You’ll need

• Sharpie Permanent Marker
• Flat head, and Philips screw drivers
• Hobby knife
• Pair of pliers and cutters
• Soldering iron
• Solder Extraction tool (vacuum tool) *
• 3.7 v, 5mm, 2600mcd > Blue LED…or whichever color you prefer
• solder
• heat shrink/electrical tape *
• hair dryer/ heat gun *

*optional, depending how you do the mod

First we have to open up the mouse, you have to locate 2 (or more depending on mouse) screws that hold the bottom and top together. In my case one screw is located under the batteries, and another at the tip of the mouse, covered by a sticker.

By taking a flat head screwdriver, pop open the battery cover, and then take out the batteries. Now take a Philips head screwdriver and unscrew the screw. Once that’s out of the way its time to unscrew the screw under the sticker; you can just stick a screwdriver in and unscrew, or cut around the sticker…or whatever way you prefer to do it.

Now gently lift the top portion of the mouse off. Now place that top somewhere you wont scratch it, melt it or whatever. On the left hand size, closer to the end of the mouse you should see the LED. (And again, if you’re not modding the MX700 mouse, then your LED is probably somewhere else.)

Now grab the little green PBC board, and pull it out of the plastic clip…be gentle, don’t jerk it; if you do you’ll snap the LED holder clip. Now, there are two ways to go here:

1. Unsolder the LED and take it out, using the vacuum tube. Then put in a new LED, and solder it back into place. 2. Cut off the PBC board and solder the new LED to the wires.

I tried to do method 1, but I really can’t figure the vacuum thingy out…so I went with choice 2. The methods basically explain it all, but ill chew it up more for you. Take a pair of wire cutters, and snap of the wires that are attached to the PBC. Cut as close as you can. Now take the hobby knife, and strip off as much plastic coating from the wire as possible. Now take your soldering iron, and melt off the rest. I would really recommend melting plastic with a soldering iron, but there’s just inst much wire to mess around with wire strippers, so melting is ok. Since I am on the subject, now take the hobby knife, and clean off the plastic from the soldering iron.

By now you should have a wire with bare ends. It is time to cut off a small piece of heat shrink, or a small piece of electrical tape. Put the piece of heat shrink over the LED legs (if you’re using electrical tape, hold on just a bit). Pick up the LED by the shorter leg, get a soldering iron; dip it in solder. Now holding LED in one hand, and soldering iron in another, and heat shrink on the LED legs, solder the longer leg of the LED to the red wire…or wire that has a red stripe on it. Do the same for the other leg. Now put the batteries back in the mouse, if LED lights up, your good to go. If not, unsolder the LED, and solder it back with LED legs the opposite of how you attached it the previous try.

If LED lights up, were basically set. Get a hair dryer or heat gun, and shrink the heat shrink. If you’re using electrical tape, wrap it around the LED legs. Now take the LED by its legs, and bend it a little, and put it back in the LED holder, push it in, so you hear the clip snap, or the LED doesn’t go anywhere. Now try to move the mouse around, and see if it works. If you see the cursor moving on your screen, you have successfully modded your mouse. If not, try to push the LED farther in, or bend a bit to the side and such.

NOTE: My mouse stopped responding; it took me rebooting and then a reconnect in windows. You do this by getting another mouse, going to control panel, and clicking mouse options, going to Cordless tab, and clicking connect. With other mice I have modded this never happened, so I am guessing this happened to this one because its wireless. If you’re using a regular mouse ignore the reconnecting, reboot should just do it.

If your mouse works perfectly, its now time to reassemble the mouse together. Take out the batteries from the holder. Put the top part back on; and screw the 2 screws back in. Put the batteries back in, close the battery holder. Congratulations you have successfully modified your Logitech MX700 mouse.
