MacBook not charging. Charger showing green light!
My MacBook died on me a few days ago. I can't seem to boot it up. At first I thought it was the battery and I replaced it and it seemed to work fine, but the green light on my magsafe adapter stayed on and the battery drained. The battery I replaced has 114 cycles, so I thought maybe it was just a bad battery, but realized it wasn't the battery, but my mac. I noted my magsafe port was melting and peeling off so I replaced the a few days ago, but my MacBook still wont turn on. It will if I put in a fully charged battery, but it's basically useless every time it dies. I bit the bullet and contacted apple and was told my mac was considered "vintage" and "obsolete" so they wouldn't be able to fix it for me.
I want to at least get it so I can back up my hard drive to my external one. I know I should have been keeping up with backing it up periodically, but I didn't.
Things I've tried was new batteries, changing out the magsafe port, resetting the SMC.
Could it possibly be the logic board and is there a way for me to fix it without loosing all my data? I would like to salvage my mac is possible, I've had it for years and until now it hasn't given me issues.
Update I ran a diagnostic on my Mac and it came up saying 4xxx/4/4000005: oòyä “battery”
This is another new battery in place.
UPDATE: this is my info from rubbing coconut battery. It says battery failure even though this is a newly purchased battery....
