Dell Inspiron 1501 Keyboard has 11 keys that don't work. Spread all over the keyboard in small groups. I'm assuming it's a standard X-Y matrix with an open trace somewhere. Haven't found any hints that there's a standard for such things.
If I had five hands, I could probe the thing in place. Not much chance of connecting the cable otherwise.
Been thinking about measuring capacitance at each line and watching it change as I poke a key. Or injecting RF and tracing it around with a current probe on a spectrum analyzer. I once fixed a matrix by hitting it with a stun gun and looking for the arc.
Any clever ways to figure out where the line break might be?
Yes, I know I can buy a used keyboard for $8, but that's 8x what the laptop is worth, and I wouldn't have nearly as much fun.
Thanks, mike
