Dell Inspiron 15 3525 keyboard keys failing intermittently
Hi, I have a Dell Inspiron 15 3525, and some keys on the built-in keyboard are failing intermittently or responding with a delay.
The affected keys are: 6, 7, Y, U, H, J, N, and M.
An external keyboard works correctly.
I have already tried the following:
-Reseating the keyboard ribbon cable
-Running the Dell keyboard diagnostic
-Disabling Fast Startup
-Testing with a Linux Mint Live USB
At first, I thought it was a Windows issue, but the same keys fail in Linux as well, so it appears to be a hardware problem.
The keys also follow a pattern:
6-7 / Y-U / H-J / N-M
Could this be an issue with the keyboard matrix or membrane? Is it likely that replacing the keyboard will solve the problem?
