OK, so, here’s a bit of an interesting problem. I have a 13” MacBook Pro 2009, that’s had light fluid spill. Starts up, but got really hot around the area where the charger plugs into the machine (not the area where the battery is). I thought it might be the charging port, so I cleaned that out, and am somewhat afraid I might have cleaned it too well, as I’m not sure the bare metal is supposed to be showing (see picture below). Anyhow, it gets slightly less hot now, but during install still gets a bit warm on the quarter of the machine that’s on the corner where power plugs in. (not super hot, maybe 35-37*C) During install, power seems to indicate battery is charing, but without percentage, and I’m not even sure system recognizes battery. When charger is removed, all power dies. Does this system sound like it’s safe running? Mainly asking as I don’t want anything to explode in my face. No signs of fluid spill damage inside as far as I can tell. Thanks :)
HI @opux , The problem you are having is probably due to the liquid spill and the issue could be the following; The battery charging circuit is damaged, suspecting that the diode on the input that merges the battery and the charger line is faulty. It happens on older Macbooks, seen that before. Sometimes it can even occur without any exposure to liquid.Faulty battery (due to water spill or age) The bare metal showing is not a huge issue, you only removed the contact damper plastic/silicone stickers that hide the bare magnets. You should feel that the charging connector holds stronger on the magnets now. I would take out the whole motherboard and have a closer look to make sure that there are no other parts liquid damaged. If I were you, I would take out the battery until you diagnosed where the fault lies, in case you (further) damage your battery as it might be saved.
