I can’t believe it. Just a plain sheet of paper. Great tip!!!

My keyboard also has the hex head on the outside. The T5 worked well.

Were you able to repair your keyboard trace ? I was able to repair all the problematic keys except the spacebar. All the keys around the spacebar are working perfectly, no other breaks on the traces and no lines crossed. I spent a full month staring at it!

This is a very good guide. I had one spill after another and a few keys on left side no longer worked. I cleaned the keyboard and left it disassembled to dry out for a week. I was hoping a simple cleaning would help. It didn’t. Since conductive pens are a bit pricey in Canada I decided to test by using tiny bits of foil where I knew I had a faulty key or break to be sure a pen would work. With the foil I can get most of the keys to work but not all. Do you think a pen will produce better results or is it done ?
