Keyboards and Keyboard/Mice Combo Sets

Is there any information for disassembling the K750 keyboard? Mine has had a spill on it. It's still working fine, but I would like to take it apart and clean it up.

Any help would be greatly appreciated.

Hello mordraid,

I would not recommend disassembling your keyboard.  You will void your warranty.  I would recommend letting your keyboard dry thoroughly (if it hasn't already) and continue to use it.  If your keyboard begins to malfunction, then contact Customer Care in your region.

I hope this helps you out.

Sincerely,

Um... thanks but the OP didn't ask your thoughts on whether or not she should disassemble his keyboard. He simply asked if anyone knew how.

I as well have spilled something on my K750 keyboard that makes the keys sticky. I as well need to know how to disassemble it so I can clean it.

It is NOT a warranty issue. I have clearly voided the warranty by spilling coca cola all over it.

So in the future, if you don't have anything helpful or on topic to say, then please refrain from responding.

Hello Radwarrior,

I cannot advise anyone on how to disassemble their products as it will result in a voided warranty.  Even though something has been spilled on your keyboard, I would still advise you to contact Customer Care for your region to see what options are available to you.  Even though this may not be a result of a defective piece of equipment, Logitech may still be able to replace your keyboard. 

I hope this helps you out.

Sincerely,

Thinking the keyboard may be assembled like an iPhone, I tried prying it apart from the edges. I pretty quickly realized this was wrong.

The keyboard is held together mostly by glue, but there are about 24 small screws that hold the top frame around the keys, down to the bottom case. They go through two metal layers that are sandwiched in between and lend support to the whole thing.

Unfortunately the screw heads are covered by the shiny layer that goes over the top, and it is glued permanently to the top of the keyframe. Any attempt to disassemble the keyboard will result in the complete destruction of the keyboard.

So, though I love the Logitech K750, it is a disposable keyboard. If you spill on something on it and the keys get sticky, just throw it away.

Thanks for that Radwarrior.  I was considering taking it apart until I read your post.

So instead I just turned the power switch off, poured rubbing alcohol into the keys an ounce or so at a time, pressed the sticky keys a lot and let it drain out the end by holding it vertical.  Did that a couple times and after leaving outside on a hot day and with the sun on the back while vertical to dry, it worked fine.  I left it overnight since it was a windy, dry summer night and I wasn't worried about condensation.  Had to repeat it a month or so later as a couple keys were still sticky and finally annoyed me enough to repeat.

Some alcohol got in between the solar panels and the glass both times, but didn't cause any problems and evaporated, leaving no trace.  Has been working fine for months.

A bit harshly put. I actually managed to remove the quite loosely glued cover from my keyboard without destroying anything. Yes, you'll probably have to glue it back using your own glue, but that's about it.

Actually, after spilling a nice 4dl cup of coffee on my keyboard, the hardest part in cleaning it was about deciding whether I should use a piece of moist, soft cloth or a small sponge to clean up the sticky coffee from between the layers. After wiping the silicone layer (the one that looks like a circuit board) clean and letting the keyboard dry for the night, all my double key problems were gone (boy, was I relieved. Tossing a whooping 90e keyboard away would have been hard).

So, if you spill anything on it, don't be afraid to take it apart, it's quite possible. The top cover comes off quite nicely with a sharp knife (I removed mine starting from the top right corner just above the solar panel) and the rest is just about screws and stuff. Of course, you'll have to remove the keys to be able to clean between the layers,  but just being careful is enough here, too.

Don't disassembly your keyboard!!

There's no need to disassemble the keyboard... I figured this out after I pulled mine apart.
 :-(

Simply lever each sticky key off from the middle bottom edge, one by one, then VERY carefully remove each hinge.

DO NOT ATTEMPT TO DISASSEMBLE THE HINGES!!! They will break.

Wash the keys and hinges in hot water, and clean the newly exposed parts of the keyboard, let them dry, then reassemble.

Thanks GlenSullivan! This is exactly how to do it. You don't even necessarily need to remove the hinges completely (to avoid snapping them).

How I did it:

1. Gently pry up the bottom of each key with a knife (right side instead for the function/media keys).
2. You will hear a slight pop as the key snaps out of its slot - don't worry.
3. Lay the key horizontal without pushing it back in.
4. Lift the key out of its slot.
5. Soak a Q-tip in rubbing alcohol.
6. Thoroughly scrub down the back of the key.
7. Gently lift the top edge of the remaining scissor hinge and scrub on/around/beneath the top area of the scissor.
8. While still lifting the top edge of the scissor gently insert the Q-tip through the gap at the bottom edge of the scissor and scrub as much as you can on/around the scissor and the rubber button.
9. Place the removed key back on and snap it back into place.
10. Repeat with all other keys.

Good luck to all!

Thanks for the info. I have another kind of issue which I will try to sort out by disassembling the keyboard. After a couple of months of use, the battery refuses to recharge fast enough. I returned my first K750 for this reason, but the replacement behaves in the same way. It takes 1-2 hours of charging at green levels just to keep it going the rest of the day.

Since the ML2032 batteries are not available for purchase, I will try to disconnect the solar panels and use CR2032 batteries instead. It's not exactly what I bought the keyboard for, but it completely fails to deliver what it promises to someone like myself who has to type a lot everyday. CR2032's are very cheap and in theory they should work if you disable the recharging.

It's a great keyboard. I love the slim form factor and the feel of typing on it, but it simply doesn't recharge enough. As it is winter in Finland, there is no good sunlight available for many months to come. The place I bought it from say they can't keep on giving me fresh keyboards, and as it apparently works as intended in their view, they will not reimburse me. So much for warranty. I hope this little experiment works.

Logitech: Please sell replacement batteries. Better yet, give me one since this keyboard apparently needs more than one.
