Hello, for some time now few of the keys on my laptop (model AN515-55-538D) stopped or struggle to work, f.ex. 2, 4, 5, 0, Backspace, k, o. Sometimes it is all fine, then suddenly they are not responsive or react after a while. I looked over the internet for some answers but none gave a solid solution. I even did EC Reset (25 seconds Power Button with disconnected power supply) but it only helped for a while. Uninstalling keyboard in Devices Manager didn't help either. Please help.

    Hi, try the On-Screen Keyboard option (OSK) if that works OK Open Device manager and disable the Standard PS/2 keyboard device in Keyboards and just reboot.

    I have both disabled and uninstalled the PS/2 keyboard and rebooted the laptop. Solution was only temporary. The symptoms appear and disappear whenever they want to

    Try using PowerToys to remap the keys to the same value. See if that works.

    Tried that. In PowerToys I can't remap keys to the same values, the program prohibits that.

    I just checked which keys are faulty: ~,2,4,5,7,+,o,k, from thr main keyboard and: 2,4,7 on the numeric keyboard. No idea what it is, especially that it is not a permanent issue, like it has a will of its own

    In this online keyboard test, are the keys in question not recognized either?

    Right before I entered the Key-Test website the keys started working again but they behave like they have some kind od latency or react after a while and when they finally do, they work fine. Problem is, that this is only temporary situation cause it happened a lot of times now. They will cease to work in a while - no permanent solution. Before I just opened a text file and checked them key by key

    Have you tried cleaning the keyboard connector with isopropyl alcohol?

    You mean the pin cable? Yes already did that. Key connectors on the other hand require complete disassembly of the laptop because keyboard is only accessible from the bottom of the computer. By the way, if I would want to get a new keyboard, could you tell me how many pins should it have for this exact model?
