What are some cases in which a magsafe board might be damaged and require replacement?
Magsafe connectors seem to arc a little bit when connected/disconnected. Over time, they degrade and eventually can need replacing.
Unbelievable how little thought is put into the replacement of parts that are likely to fail in these machines.
Thank you a thousand times!!!!! This guide was fantastic. Followed every step and my MacBook is back in action.
Awesome guide, thanks! My magsafe connector started getting very hot when charging and eventually stopped working entirely.
Full functionality restored. One thing that needs a better explanation is how the hinged ZIF connectors are opened, such as that for the keyboard.
i broke all of the speaker hinges on the motherboard any fix around this ?
