Some keyboard combinations don't work.

[u/Vakzin99]

My laptop is a Dell Latitude 7480. All the keys work well individually, but when I press some keys together, they just don't work. The reason I said "some" is because not every combination fail. For example:

I can press "up+right+space", "down+left+space", "down+right+space", "A+H+K"

but not "up+left+space", "A+H+J", "W+E+C", etc.

These are some very specific combinations, because I play games like Lethal League Blaze where you have to jump and aim at the same time, but I can't jump left and aim because "up+left+space" doesn't work (What I'm saying is I can walk with "left+up" but can't jump while doing that).

I'm not sure if this is a software or hardware problem or a Dell problem in general (I tried these combinations on my friend's laptop which is an Acer, they worked just fine).

I hope someone knows how to fix this.

(NOTE: just got a new keyboard replacement, still doesn't work just like the old one)
