 Hi my name is Bobby and my hobby is fixing broken Mac’s and then donating them to people in need and our troops that need a laptop while on deployment. I live in the southern US and look forward to asking you for help in obtaining board views and schematics for problems I have trouble finding. Thanks to all in advance!Comment

 Hello Everyone, Im a fresh-from-college kid that has always had an interest in computer repair, I do it mostly on the side as I program PLCs as a career. Today as I am posting this I have an HP Probook that is unable to use a regular windows account as it was previously owned by a compony who made it so only people with their email subdomains can sign up. Im still relatively new to this so if anyone has any tips or tricks of the trade that they wish to bestow upon a raw mind like mine I would appreciate itComment
