Wow, that amazing story.
that is journey of life, to be come an active person, person have to work hard to get a peaceful life.
That remind me my passes when I started repairing laptop too, I don't have idea but I put my full focus and attention to get it right, I got my repaired kits and I stated processing the board, I stated guesting if these or that chip bad, I only gest right if the chip burnt or heating, if I couldn't able to repaired I gave the pro to help me repaired it and pay them, so before I couple the board I will take a look what and what they touch and what they change on the board to know if I gest it right, gradually I started making board's to work.
Now the most challenging is bios and Badcap has being taking impact of it.
