Why do half of the Acer Aspire e15 keys stop working all of a sudden?

Question

Keyboard

Hello!

Yesterday, during the layout of the site, some keys on the laptop keyboard just for no reason stopped working (1, 3, Q, T, U, right arrow) , and the number 3 is not pressed both in the upper and in the right part of the keyboard.

Today I went to the site for an online test of the keyboard, to write down which buttons plow and which do not, and while I was pressing everything in a row, all the keys suddenly worked (at that moment I was pressing shift, ctrl, windows, caps lock, alt), then again walked through clave and again the problem returned.

Who knows, maybe there is some kind of key combination that includes such a "xs for the mode" of the keyboard, or is there a problem in the hardware?

Answer 1

The flexible cable of the keyboard breaks. A slight movement restores contact.
Change Claudia, what to do.

Answer 2

I think it's worth trying to hold the Fn key in this mode and pay attention to the third marking on the "problem" keys (the same color as Fn)
Well, then look for the combination Fn + ScrlLck / Fn + NumLck to switch)
