Charger dead after Macbook got hot while using it

Hi all,

Last week I was using my laptop and some apps were working hard, and the Macbook got quite hot. The charger was plugged in, and suddenly I noticed it sopped working because the screen light was dim. The light in the charger went Off. As I had enough charge, I disconnected it (it felt really HOT!) and went on with my work. Later I plugged the charger again but it was dead, it didn't work or light up at all.

So I had to rush to an Apple reseller and buy a new one. I already had another one for emergency, but I like to have two, one I use always in a fix place near the TV set in a Henge dock, and other one I can use while in the sofa.

Both chargers are connected to a UPS to avoid any problems.

Now I was deleting a lot of old emails in Apple Mail, and it got hot again, I installed iStats Menus and I know CPU Die sensor was 93ºC. The charger I was using (the second old one I have) just disconnected itself! Just as soon as I noticed, I unplugged it from the Mac and the UPS to let it cool.

Fortunately it still works 😀

My question is, What is happening in my Mac, is this normal or happened to you? This shouldn't be normal at all. I know it can get hot as it disipates the heat through the metal body, but burning chargers like this is a little bit of a problem to me.

Computer is the one in the signature: MacBook Pro (13-inch Late 2011), OS X Mountain Lion (10.8.4).

Please bear with me, as English is not my mother tongue and sometimes I make mistakes.

Your English is just fine.

You might want to examine the power adapter connection on the MBP and the power adapter it self. Look for any debris or discoloration.

Try a SMC reset:

Run an Apple Hardware test and see if it picks up any clues;

You may need to use OPTION and D keys to start it.

Open Activity Monitor and set it to show ALL PROCESSES and %CPU to display values from high to low. When the MBP gets hot post images of Activity Monitor and iStat menus temperature readings,

Post this from System Information:

If we cannot identify the problem, then the Apple store or AASP will be the place to go.

Ciao.

Well if the second charger is working for you then thats great news.

You can also download Fan Control for mac. and you can select manually your highest and lowest temp, and fan speed. I have it installed on my mac. I set all my parameters to the lowest possible.

Adding more ram will make your system perform better, with lower power consumption. With too little ram (4gb is not that much these days) you system goes into virtual memory to make all your programs work. also called swap files, or paging files. Once your system starts to access those paging files, you start using your harddisk, which slows it down, as it is not nearly as fast and effecient as ram itself. so you for sure would want to avoid your system from usng virtual memory. If you look at your memory consumption, don't be fooled by the number you see. Your system allocates a certain percentage of memory for other things rather than the program thats demanding more ram. So even though the system may say theres suffcient ram, there really is not. 8gb of ram should do the system good, like milk does the body good 🙂

If you're going to upgrade your system, to SSD etc. why don't you wait, save that money, and buy a new updated mac, with 802.11ac wireless performance, and updated graphics cards usb 3.0 inputs etc. I think your money will take you into the future that way.

I hope this all helps.
