My SMC reset isn’t working and the battery is also not charging, I tried changing the battery to see if it was faulty but the other one still wasn’t charging and I also changed the MagSafe but still it wasn’t charging The battery is now dead and it won’t start up, the MagSafe light is green, and the battery meter by the side (the one that has a tiny button) blinks 3 times then the last one fades out It also starts itself automatically when i plug the MagSafe and doesn’t boot up but it keeps beeping continuously (this started happening after I unplugged the battery indicator from the inside, i returned it but still) Please help!!
