Logitech K750 keyboard disassembly guide

Schwierigkeitsgrad

Easy

Schritte

Zeitaufwand

15 - 20 Minuten

Einleitung

Half disassemble the keyboard for deep cleaning.

Werkzeuge

Schritt 1

Carefully remove the battery by levering it with a flat screwdriver

Schritt 2

With a hair dryer, heat the cover and pull little by little with your hand so as not to break it.
Note: Some marks may appear on the plastic if it is pulled incorrectly.
Do not heat excessively

Be careful - it’s really easy to melt the keys! The glue doesn’t need much heat so go easy. Once I got one edge lifted I didn’t use heat for the rest, just levered it up with a plastic spudger.

I did not need heat to remove the top layer. Once my pry had loosened the corner and left edge I was able to smoothly (SLOWLY) pull up the covering plastic. It went back into place with no issues. Be careful as the spot above the arrow keys will be a tough spot as well as the logo potion at the top center.

Schritt 3

After removing the cover, the screws are visible

Schritt 4

Note: Consider placing the screws in the same order that they have on the keyboard to help you with the reverse process later.
Unscrew the 28 "PHILIPS" screws, order according to output order as they have different heights and diameters.

Schritt 5

Carefully pry up the tabs around the keyboard body. Between the F8 and F9 keys there is another tab. To open it, raise it a little from below and lever it with the screwdriver, as if we were going to screw.

The keyboard is flexible enough that you can loosen the tabs at the top and bottom edges of the keyboard and lift from the middle to release it from the outer end tabs. From there you have full access to the underside of the keyboard for cleaning. A little canned air and isopropyl alcohol cleaned mine right up.

Schritt 6

Once the previous steps are completed, we would find the keyboard half disassembled.
Warning: Be careful to center the plastic cover on the keyboard perfectly.

Schritt 7

To reassemble it, follow the same steps in reverse. Watch out for the plastic, it has to be completely centered.

Abschluss

Recommended to remove that dirt that remains between keys, and that cannot be easily removed, it is very easy to do, and with simple tools.

May I ask if the keyboard was opened with a repair in mind or simply to illustrate the process?

A few keys have stopped being very responsive on my keyboard and I am looking if they can be fixed.

Hi Georgios,

I also had a button that wasn’t working well. This is why I tried to disassemble it. Since these days of confinment I did it again but followed a little more, I can recommend you that you won’t see anything since it is like a laptop keyboard also you also can damage the black label that is very sticked. This 2nd time when I did this process, I melted down one button (the left arrow) and now it is deformed and I had to repair it.

Since the keys mechanism is same as on laptop keyboards, you can try to pull it up by the one side and then the other side with care to don’t damage it.

In my case, the problem was dirty under the button that was sticking the membrane each pushin. I cleaned with alcohol and a small brush and restore it’s functionality.

Muchas gracias por el tuto!!! aunque me da algo de yuyu el tener que despegarlo... pero me veo que me tocará hacerlo, no se pq la F8 me da pulsaciones sola… Una duda… con que lo has vuelto a pegar?

hola,

l primera vez use su propio pegamento recalentando pero la segunda vez, quite que lo que habia original y use cintas finas doble cara. a mi me ha quedado mal pegado. la proxima vez usare cola de contacto como para las pantallas de los moviles. creo que debe de ir mejor
