Hyyker X Range E Keyboard: Issues with Keys Not Responding - Causes & Solutions

Hello, as in the title, nwm, what is caused by the fact that sometimes they are used, I do not write, I am terribly irritated, formerly it wasn't: / greetings and please help

Buy a new keyboard, do not throw away the old one but dispose of it at an electronic waste collection point. This is very important because it helps to care for our natural environment in which our grandchildren will grow up one day. greetings

I want to fix it

If you want to fix it, go ahead, put a screwdriver in your hand and get to work.

Nwm, and what can it be caused by? I have no guarantee but there is a lot of dust, maybe because of it? I cleaned it with dust and I heard that the keys were rinsed with running water and the keyboard thoroughly cleaned with sticks and if a button broke, give some alcohol inside. How much truth is there?

It is necessary to unscrew it gently and carefully, clean it from dust and wash it under running water (a little detergent for the brush can help remove old dirt) the case - hello with the keys first of all. There is a plate under the keys (two foils with dusted paths and contact fields most likely) - keep water away from it. This plate (but if it is dirty) can be tried to gently rinse with IPA (isopropanol) an ear stick or a cotton swab in wetted IPA. Dry, fold and check if it works. Like this - I will work the same as before, and there will be problems - the films are worn and you will do nothing; or utilization.
You can try.

PS When washing the paths on foil (if it's such a construction) be careful - contrary to appearances, they are quite delicate.
My current keyboard is already 6 years old on the meter and works after washing three times. The trouble is that the inscriptions on the keys begin to wipe, and "from memory" to write I have not learned and probably will not teach. In any case, thanks to periodic cleaning I extended her life by a few nice years - which is not without significance for the environment ...

PS 2.
Now I just looked - it can be a problem, because there is no foil in yours and there are mechanical buttons with contact plates shortened with keys ... You can replace these switches (provided that it gets ...) but the works ... pile. In addition, the cost of such an operation (buying retail switches are more expensive than wholesale) is unprofitable, and with the cleaning of switches even more work and (contrary to appearances) the cost is also considerable.

Seriously the whole keyboard because one thing sometimes doubles, come on.

Added after 7 [minutes]:

I meant to wash the covers on the switches under running water, clean the keyboard after the baskets with a soaked cotton swab and touch the switch with an alcohol-soaked ear stick because I did not understand your speech. with the rest of the problem that it repeats once every 10 times but it is annoying, what can it be about, it is mechanical on blue switches, I will add that as a downloadable overlay from the switch on e this problem disappears, maybe you need to wash it / replace? can I wash it under running water?

So for anyone with a similar problem, take apart the switch, preferably desolder with a tin sucker, but I just pulled it out, and see if such a metal protruding post is not bent or something, it should enter the hole, if it is not straighten it and put it back in the keyboard, ready.
