How to Open the Logitech G502 Lightspeed

Difficulty

Moderate

Steps

Time Required

20 - 30 minutes

Introduction

Follow this guide to open a Logitech G502 Lightspeed.

Opening the mouse requires removing its feet (skates/pads). If you plan to reuse the feet, you’ll need to apply heat to loosen the adhesive and avoid bending the feet. Bent or torn feet may require replacement.

Step 1

Before you begin, flip the power switch into the OFF position.

Step 2

Heat an iOpener and apply it to the mouse feet for one minute.
You may use a hair dryer or heat gun. If you do, set it to the lowest temperature setting and apply heat for 10 seconds.

Step 3

Insert the tip of an opening pick underneath the front foot at the gap in its recess.
The mouse feet are made of two layers. Make sure you insert the pick under the bottom layer to completely remove the foot.
When possible, grab with your fingers and slowly pull to peel it off completely.

Step 4

Insert the tip of an opening pick underneath the tiny front right foot at the gap in its recess.

Step 5

Insert the tip of an opening pick underneath the rear foot starting at the gap in its recess.
When possible, grab with your fingers and slowly pull to peel it off completely.
When installing a new foot:
Use a spudger to carefully scrape up and remove any remaining adhesive bits.
Use isopropyl alcohol and a microfiber cloth to thoroughly clean all adhesive residue from the foot recesses. Allow the surface to completely dry.
Remove the feet from their backing and firmly press them into place.

Step 6

Use your fingers to remove the weight hatch by pulling the bottom part of the thumb rest straight down.

Step 7

Remove the four 5.4 mm long Phillips screws at the underside of the mouse.

Note: The beginning of this guide says to use Phillips #00 but my iFixit #000 fits correctly.

Step 8

Insert an opening pick between the bottom plate and the upper shell starting at the rear of the mouse.
Slide the opening pick along the gap between the two halves towards the outer flank of the mouse.
Twist the opening pick to disengage the clips holding both halves together.
This might require more force than anticipated.

Step 9

Again insert the tip of an opening pick between the bottom plate and the top shell starting at the rear.
Slide the pick along the gap between the two halves towards the thumb rest.
Make sure to follow the curved geometry to keep the pick in the gap.
Twist the opening pick to unhinge the remaining clips.
This also might require more force than anticipated.

Step 10

Flip the mouse over on its (removed) feet and hinge the top shell open towards the right side.
Don’t remove the top shell all the way yet. It is still connected to the bottom plate via cables.

Step 11

Hold the battery cable close to the connector and carefully "walk it out" by pulling parallel to the motherboard rocking the connector side to side.
Grip the cable as close to the head as possible to avoid damaging the socket.
You can also use a pair of angled tweezers to grip the connector head and pull it straight out of its socket.
If you're having trouble, insert the points of your tweezers into the small rectangular holes on top of the socket and push the connector out.

Using a hard sewing needle and pushing the connector out by inserting the tip in the two rectangular holes, alternating. Mine has really soft cables and wouldn't come out by "waking it out". I was afraid to not rip the cables out.

Step 12

Use a spudger or your fingernail to flip up the small, hinged locking flap of both ZIF connectors to disconnect and free the interconnect cables.
If the cables don’t pop out by themselves use your fingers to lift them out of the sockets.

This is great to open the case.. be careful if you want to disassemble further.. there are at least 20 more screws if you want to completely tear these down

Conclusion

To reassemble your device, follow these instructions in reverse order. Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).

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

Needs top half disassembly for micro switch swap

Adrian Kennedy -

Check my link at the bottom

Lloyd-Steinar -

This helped so much! I had the button to turn on infinite scroll for the scroll wheel stuck and this allowed me to get it most of the way taken apart so I could take the rest apart myself.

Gerry Porter -

Well, we've got it half way apart... Now where's the second half of the guide? lol

trevorsklar -

comes in a paid dlc

Artemiy Bzhedugov -

Check my link below

Lloyd-Steinar -

DLC for second half of the guides is in development (waiting to be baught like Blizzard or Bungie—jk)

Try scrolling up backwards through the guide to to close it ;)

"To reassemble your device, follow these instructions in reverse order, …"

Or if you need to replace the battery, check the device page.

I somehow fixed my scroll wheel for about 20 mins, then it broke again. Did plenty of searching online and found this Reddit guide. It's so insanely helpful, especially for someone who is terrible small parts. I managed to fix my mouse again, but not sure it will last and I also broke the infinite scroll option while tinkering with the parts. Regardless of my situation, the Reddit guide is incredibly helpful!

This is only 30% of the disassembly, not helpful. Especially because it comes above actual tear downs in Google results, congrats you covered the obvious steps...

Simon Schwierzeck -

Great guide, now just need to find the teardown of the board so I can replace switches, etc. I seen your battery replacement but havent found the board one. Thanks anyways
