For the 6th time on the forums, my dad's dell makes its appearance. This has been a clear issue since its, *episode*; None of the backlight keys on the top of the keyboard work, the only one lit is the volume mute button, it will not turn off.
I do beleive this to be some sort of error code, because as I was messing with it, it would show different lights as it started (with the fan clogged, volume increase was lit). However, after I was finished fixing it, I ran bios diagnostics for a whole 3 hours. It came up with nothing.
I need this fixed because I am getting paid to fix my dad's laptop(needs to be "better than new" to impress him, so broken buttons won't cut it).
