Hi everybody, I´ve been reading this forum for a while, but never felt like contributing something though I like your posts and ideas. This might be a long one but I think this is the best place on the web to get a good answer. Anyway, I have a question about my 2010 Macbook Pro 13 Inch. Since last Tuesday I continue to have connection problems with my Magsafe Power Adapter. This wouldn´t be a big problem but as I use the computer for DJing, I don´t feel safe showing up anywhere with this anymore. The Connection Problems are quite minor and wouldn´t be noticed by a standard user but I really care for my Mac so I might be a bit into details. Up until Tuesday, everything was fine. I could plug and unplug the Magsafe and everything would work, charging, normal use without battery, all is ok. The problem is quite simple: When I plug in the MagSafe, sometimes the LED´s don´t light up. Then there are two cases, when in use, the system sometimes shows me that the System is on the MagSafe but not charging the battery (which isn´t full). Sometimes, the System doesn´t notice the Magsafe at all. When it goes into charging, charging is really slow (For example, the Battery is at 97% and the charging takes 15 Minutes). When I shut the computer down, connect and disconnect the Magsafe, the same phenomenons appear. Sometimes, no recognition, sometimes no charging. The direction in which I use the adapter doesn´t matter. I have already ruled out several problems: I checked the two Connectors on the Magsafe, no change. I checked the power source (of course!). I also ran an Apple Hardware Test (bootup with the system disk + press d and in the "long", detailed version) for three times in a row and all went well, so I rule out any problems with Drives, RAM or the Logic Board. I also cleaned out the Magsafe and the Magsafe Connector using Isopropyl Alcohol (>90%), no change. I read the Apple Support Page about the topic and my adapter looks quite similar to the examples. A bit used, but I´m a poweruser and the MBP runs for about 10-20 Hours a day (every day !), I used to switch power sources about 3-4 Times a day. Coconut Battery Output is as follows: Currrent / Maximum Charge = 5019 mAh. Current Capacity = 5019, Percentage: 87% . Age of Your Mac: 29 Wks, Battery Temperature: around 30° Celsius, Battery Power Usage: between 15 to 30 Watts, sometimes 60 when under full load and on battery only. Battery Loadcycles 203. There is nothing that ever happened to the system, it was used in Clubs and other Party Events, involving higher temperatures, humidity and artificial fog, everything went like a charm. The Performance is still perfect, there are no errors, just a longer boot time but I think the reason for that is that a good 75% of my internal drive is full. I never opened the Mac and there were no accidents. I would love to go to a genius bar or Apple Store but all I have in reach is "certified dealers", I don´t trust them and don´t want to send the MBP to Apple as this would take at least a month. What should I do? Do you think this is rather a Adapter-Related Issue, or is it something that needs serious repairs? Thank you and all the best!
