I have a late 2009, macbook white, which up until a couple of days ago worked perfectly - now, every time I’m attaching the magsafe connector to the laptop, the connector itself heats up quite a lot in a matter of minutes. It works ok if I try to recharge the battery whilst the laptop is powered off, however every time I’m trying to recharge the battery with the laptop powered on the connector heats up to the point that I can barely touch it. I can’t figure out what is to blame here; is it the connector from the cable at fault, or is it the connector inside the laptop, or the battery? Also now, the connector only charges the battery if I fiddle with its position a bit. Any input into the matter would be much appreciated: Thank you! Update (06/11/2014) oh and does anyone know how I can safely dismantle the MagSafe connector? I’d like to check the wiring, before buying a new charger.
Sounds like the DC in board needs to be replaced in your MacBook. As you didn’t tell us which model you have I can’t supply you the part number. Review the IFIXIT guides for your system to learn how to replace the part. Some people have encountered issues with the insulators breaking down in the connector in the system. I would also recommend you inspect the contacts to see if they are damaged (melted plastic) on the charger as well, you may need to replace it as well here.
You are risking a fire, and damaging your laptop. Get a new charger there’s a short in the connector block of the magsafe. If this answer is acceptable please remember to return and mark it.
Thanks @pareshradadiyayuvi it worked !!!
