Introduzione
This is a full, non-destructive disassembly guide of the Logitech Spotlight.

-
-
This teardown is a result of the main button being indented permanently.
-
I hope it can also be used as a guide for battery replacement, PCB repair and all the things you might imagine.
-
Enjoy!

Removing the back cover:
-
The plastic cover with the "logi" logo is mainly glued on. on the top of the remote, there is a little tab.
-
Start prying with a soft plastic plectrum or a sharp knife at the bottom edge.
-
Be careful to not damage the plastic like I did - it's very soft!
-
Removing the top cover:
-
Just like the back, the top plastic cover is also just glued on and is very easy to remove.
Best way to remove the back cover is to press down firmly on the bottom left edge. This slightly lifts up the bottom right edge. Then try to get under the edge with a spugder and shove a pick under it. Get the pick under and across the whole bottom section and then work your way up from that position.
The bottom right edge ist the best to start with because the plastic is thinner than on the left edge. Try to do this whole thing with plastic tools if you don't want to damage the paint.

This is by far the most tricky part. Other teardowns describe this as destructive, however, it is possible to get it out in one piece:
-
Remove the USB-dongle.
-
For that, slip a very small flat-head screwdriver between the aluminium housing and the plastic piece.
-
I was able to wiggle it loose and get under a small lip to then remove it fully
-
Pay attention that two more plastic pieces will fall out. These are not broken of, they are there so the piece you just removed can be clipped in, whilst still having a "smooth" inside for the recepticle and USB-C charging port.
How can I position the small black plastic parts easily?
I think I just took fine tweezers, illuminated part where they have to go and just fitted them back in place.
You can see how it looks like a few pictures later. There are slots to fit them in and then you just add the cover back on top.

(1/2) This is hard primarily because the bottom of the hooks of the yellow marked plastic piece have glue under them. If the whole thing is removed, you can see that there is quite some wiggle, where the yellow piece is hooked into. Unfortunately, when the piece is inside the aluminium shell, it's a tight fit and there is no more wiggle.
The best position to insert a tool here are tthe short sides of the remote and then slightly off-center. There is a little plastic bridge at the center of each side. Best way to do this in hindsight would be:
Insert a tool at one of the shorter sides (edges) slightly off-center, lift it up a little, then damage or break the little plastic bridge. While still lifted up, insert a screwdriver or something like that into the bigger hole where the usb cable is inserted to and push in the direction where you broke of the platic bridge. By that you should probably be able to lift the plastic piece ontop of the aluminium case edge and create enough space on the other side to insert a
(2/2) tool and lift up this side and release the hooks. By Breaking the plastic piece and lifting it over the edge, the hook on the other side has less contact area and therefore pyring should requre less force.
This is probably not possible without leaving some visual damage on the aluminium case and the platic piece.
DISCLAIMER: dont know if that actually works!

To remove the inner plastic sled containing the actual remote, remove the following screws:
-
2 very small screws at the top.
-
2 screws where you just removed the USB dongle recepticle.
-
Remember the two plastic pieces that fell out? This is where you later have to place them again
-
When you removed these 4 screws, you are able to slide the inner sled out of the top of the housing.
-
-
-
The PCB is attached with three screws to the plastic sled. Remove them to get the PCB, including the vibration motor and LiPo battery out.
-
-
-
On the top of the PCB, there is not much going on except a lot of testing points.
-
You can also see the connection points of the tiny vibration motor.
-
-
-
This is now the interesting side of the PCB:
-
You can see the 3D antenna here
-
The device is powered by a Nordic Semi N51802. These Nordic Semis are quite common on Logitech peripherials.
-
In addition to that, a SkyWorks 2438T Zigbee and Smart-Energy Module is right next to it.
-
The Gyro and Sensing Unit is a IC268G from InvenSense
-
Last but not least, the LiPo battery is a 80 mAh jobby with 4.2V and 0.3 Wh
-
-
-
The main button is secured with two very low-profile screws.
-
Remove these.
-
The metal plate is additionally secured with a little bit of sticky tape.

Hi Dennis, awesome teardown! I wish I would've found that one a year ago :D
Btw can you your teardown to the Logitech Spotlight device page? (Logitech Spotlight Wireless Presenter)
Hi Nils, I assume you mean something like "can you add your teardown" - I unfortunately don't know how, but feel free to add it to your page :)
Dennis -
Thank you for the teardown.
This was my first ever attempt to repairing an electronic device and you guide helped greatly in replacing the battery.
Nothing broke and it worked on the first try. :)
