From my experience of disassembling and fixing several keyboards with fully or partially not working keys I can say that just cleaning contacts will not work. The membrane part of the keyboard, where the contacts for the keys is printed on, is prone to deterioration. Since the keyboard module is riveted to the top palm rest - the best chance to fix it, is to get a new keyboard assembly. It can be either salvaged from another base, or bought on ebay or aliexpress.
Try unplugging the the keyboard than cleaning the connectors and plugging it back in.
I have an Acer Aspire e5 476g. Same problem here,happened when i clean my keyboard with 70% IPA, after I assemble it back, the del,power button,ins, and backspace key are malfunctioning (dead). But then I let it rest in front of a fan to dry it off, all of the key works except the backspace key. Was frustated, have tried reinstalling the driver, reinstalling new Windows 10, and even reseated the keyboard connector to the motherboard. I then dissasamble the backspace key to inspect, but there was no broken hardware, it was bone dry, I even tried to jumped the 2 pads, but it still doesn’t work. Until today, the backspace key is still not working. Haven’t bothered to replace the keyboard since I have an external Logitech USB keyboard. TL:DR Tried to clean the laptop’s built in keyboard with IPA, ended up with a malfunctioning backspace key.
I have had some success with this problem. I found that bringing up a Word Document and fiddling around with the keys, that eventually the keys would work, but only temporarily. Shortly after the keys would stop working again. But just now, with a Word Document up, and the problem-keys working, however temporary, I held down the problem-keys and held down the on/off button till the laptop shutdown. On turning the laptop back on, the keys have been working fine. That was 30 minutes ago. I’ve been typing away with no problem. Only time will tell if this solves the problem.
