Re: Macbook heating problem
Check if the rear exhaust vent is blocked. This is the most common reason for over heating in mac books. Apple has given this statement regarding this. Also, MacBook Pro owners still experiencing overheating issues may want to update their firmware. Information Weekwrites about the mysterious update that fixed overheating issues onMacBook Pro notebooks. I have to say my notebook is running a lotcooler since the update.

Dammage caused by water only can be limited by a special service centre. By heating the system only will have more damage. And even with a scheme you won't be able to repair the macBook. You could try to order the part that is damaged. To see how to open an macbook and how to replace parts, goto ifixit.com. They did lots of repairs. There are moors sites where you can see how to opener (and close) a Mac, but star with them.

It sounds as though the IO Board is bad. Personally I would sell it on eBay for parts or Repair only. Take the money and buy another working unit. Or you can go here MacBook Air 13 Mid 2013 Heat Sink Replacement and check out this iFixit repair site . This is going to be a lengthy repair, but following the instructions you should be able to do it. I used the HeatSink repair, but you can choose any of the listed repairs for this item.
All laptops warm up during normal usage due to the moving parts in a hard drive and the system heating up doing what you want it to do, for the most cases this is normal but when the macbook gets too hot and feels like it wrong could be a problem with your fan is blocked up and un-able to blow cool air into it due to the blockage, to fix this problem you would have to download the service manual on how to access your fan to give it a clean or by taking it to a computer repair shop for fan maintenance
although this is chargeable and if you are comfortable doing it yourself then you will need to be careful,
If you need further help please ask and if i have helped you please rate me.
The green light on your power adapter is normal, this indicates that it is charging the battery. The fan within the MacBook is controlled by an internal heat sensor. The fan inside will speed up and slow down based on the internal temperatures.
The X icon for where the battery is, indicates that the battery is not connected or the system doesn't recognize the battery anymore. Meaning, you will need to buy a new battery for your computer.
The real issue seems to be that the system firmware designers haveoptimized for a quiet machine at the expense of the temperature. Theeasiest way to fix this? A firmware update,perhaps not unlike the one released recently with almost no details.Several reports from users indicated this update increased the use oftheir fans and fixed their heat issues. Isn't that an astonishingcoincedence?
Although Apple said that the update was to "System Management Control(SMC)" firmware, it was up to MacBook Pro (MBP) users to figure outthat SMC is the specialized controller that manages thermal and power conditions, and is in charge of running the portable's fans. Within hours of the update, users began reporting that the updateseemed to increase the MacBook Pro's use of its fans, and usingdiagnostic tools, claimed that their machines were running up to eightdegrees cooler.
