Apple MacBook Air 13 mid 2012 1.8GHz intel core i5 processor and 4gb ddr3 ram. 128GB SSD drive, boot time is around 6-9 seconds. This was left outside while raining the lid was open however the MacBook was turned off. When the charger is plugged in the green led blinks once every 30seconds or 1 minute, it doesn't show any leds on the MagSafe when it is not plugged in but switched on at the wall, once it is plugged in you have to hold the power button on the keyboard untill the charger blinks green which is every 30-60 seconds as I said, once it blinks it changes to fully green however you have to wait until you get the first startup screen to release the power button otherwise it just shuts down. The MacBook never fails to start and I have had it running for hours and it does not cut out. The things I have noticed while the laptop is on is that it says no batteries available and the time also resets every time you restart it, the fan is also on constant however the fan is blowing very cold air.. from the back vent. I have tested the keyboard with a online tester and all keys function correctly. This could be a very easy fix as easy as either replacing the battery or the MagSafe!. Once the laptop is shut down and the MagSafe is still plugged in it will boot perfectly off 1 press of the button until the MagSafe is removed and you have to carry out the procedure again..
