Introduction

Use this guide to open a Logitech G703 wireless gaming mouse for cleaning or repair.

Tools

Step 1

Before you begin, flip the mouse's power switch into the red OFF position.

Step 2

If you’re planning to reuse your existing mouse feet, note that the adhesive needs to be thoroughly heated to cleanly remove them.
Heat an iOpener and apply it to the bottom mouse foot for two minutes.
A hair dryer or heat gun may also be used, but be careful not to overheat the mouse—the internal battery is susceptible to heat damage.

Step 3

Slide an opening pick under an edge of the bottom mouse foot.
Go slowly, and make sure the pick is underneath both the foot and its adhesive layer if you want to reuse the foot. It's easy to separate the foot from its adhesive.
If the foot feels stuck, apply more heat before continuing.
Slide the pick under the rest of the foot until you can lift it off the mouse.
Remove the foot.
Repeat the procedure to remove the top mouse foot.

Step 4

If the adhesive separated from the foot:
Slide the flat end of a spudger under an edge of the adhesive. If the adhesive seems stuck, you may need to heat the adhesive further.
Peel the adhesive off.
Before installing new feet or reinstalling old ones, wipe away any adhesive residue from the mouse with a lint-free cloth and high-concentration isopropyl alcohol.

Step 5

Use a Phillips screwdriver to remove the four 5.4 mm screws securing the two halves of the mouse together.

Step 6

There are clips in front of the mouse wheel holding the two halves together. It is easiest to pull the halves apart at the back of the mouse and to open the clips in the front afterwards to separate them.
Don't completely separate the two halves yet—they're still tethered together by a delicate cable.
Grasp the mouse case at the back and pull the two halves apart slightly, so there's a gap at the back of the mouse.

Step 7

The front of the mouse is held together by plastic clips. They can be particularly stubborn and may require some force to pull apart. Apply steady, slowly increasing pressure to force the halves away from each other.
Insert a spudger into the small gap between the top and the bottom mouse case right above the charging port.
Pry open the mouse clips by tilting the spudger upwards to separate the two mouse halves.
The mouse halves are still tethered together by a delicate cable.

Step 8

Use the flat end of a spudger to gently lift the black sliding lock on the interconnect cable socket until it stops and the cable is no longer locked in.
Slide the interconnect cable out of its socket on the motherboard.

Step 9

Remove the top half of the mouse.

Conclusion

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.

To reassemble your device, follow the above steps in reverse order.

Take your e-waste to an R2 or e-Stewards certified recycler.

Thanks for this guide :)

It helped me diagnose the issue in my mouse and order the correct replacement parts.

One thing that I did find helpful is removing the ribbon cable before trying to unclip the top half
