Today I noticed a strange problem with my Aspire A515-51G-53JT laptop which I bought almost a month ago.
Some keys randomly stop working and it's always the same keys. So far I've discovered that the periodically shutting off keys include 1 3 - q t p ] j 3(num) 5(num) righ arrow
I have never dropped the laptop or poured any liquids on it, I got it new and unopened. It worked flawlessly prior to this problem.
I tried uninstalling the keyboard drivers and resetting the computer but the problem returned almost immediately. The keys stop working for a few seconds and then work again but it's very annoying.
Ironically, prior to buying this laptop I wanted to buy a Lenovo Legion y520 but what stopped me was the revelation that many people encounter a keyboard problem with them (same as mine but lenovo users have different keys stop working). I heard that they solve the problem by unscrewing some screws from the base of the laptop because there are three of them that are too long so they ram against the motherboard or some other components. Anyway, tangent over.
I just tested this problem by plugging in an usb keyboard and waiting for the keys to stop working. The keystrokes from the laptop's keyboard didn't work while the usb keyboard worked just fine.
Did anyone else encounter this problem?

@Srijit4Real If your machine is still under warranty get the KB replaced. The problem is probably that the ribbon cable connector from the KB to the mainboard is either loose or needs to be re-seated a few times to clean it's contacts. Requires removal of the back cover to access the KB ribbon cable and its mainboard connector as shown in the large circle and arrow below. Jack E/NJ
Howdy. I'm having the exact same problem, it inspired my screen-name lol!
I had to use Word to type this comment so the spell checker could fill in the keys that don't work! VERY ANNOYING! My new lappy worked great for a month then this keyboard issue kicked in. I called support, they suggested the BIOS reset. That worked for 24 hours then back to missing keys!! @Srijit4Real you said you returned your Acer for a fix. How long were you without your machine for? I'm dreading having to take mine in, as I need it for work and study!
But I doubt that will solve the keyboard problem, as I checked with USB keyboard, that works perfectly fine, If this keyboard problem is occurring due hard disk problem, then USB keyboard must also not work fine...
Lets see if it solves or not, Otherwise I am gonna ask for full unit replacement...
gaufchamp This seems to be the most likely explanation. The very short and stiff keyboard ribbon cable is often difficult to tightly clamp and secure on the mainboard connector while at the same time affixing the keyboard itself to the case. As a result, the ribbon often partially slips out of the connector when usuing the keyboard causing weird key responses. Long tweezers sometimes have to be used to keep the clamp closed while trying to align the keyboard with the case. You should alert your service support technican know this is a possibility.

Sorry. You don't have to open the back cover. Did my images fail to load in this link? https://community.acer.com/en/discussion/comment/622383/#Comment_622383 Jack E/NJ
Can you suggest any tutorial video or website?
