MacBook Air won't turn on, charger appears to be working

My MacBook Air won't turn on at all. Last night, I closed the screen and then when I woke up it wouldn't turn on.

I have tried the basic methods like holding the power button, holding shift with the power button and the other key combos with no success.

The magsafe charger is plugged in, once it first enters the port the light is green and then becomes orange to indicate charging. However, when I do hold the shift option ctrl keys and then press the power button the magsafe changes to green for a few seconds before returning to orange. But still the laptop won't turn on.

Now for the unfortunate circumstances - I'm currently a volunteer on a remote island so my options are severely limited. I have the ability to open up the laptop, but almost no ability to check the charger other than via the light when plugged into the laptop.

Any tips on what I should try next would be greatly appreciated, and there is a chance I could get spare parts brought to the island if I need to replace some hardware (I have experience in doing that for other laptops).

Review this Apple T/N: Apple Portables: Troubleshooting MagSafe adapters check the MagSafe connectors for damage or dirt. If the cord is damaged don’t use the charger!

Let the system charge if the MagSafe cord LED is Amber. It may take a good 8 hrs to charge. If it doesn’t then you need a new battery.

If you can get it to come on at all install this app CoconutBattery so you can check your battery, it maybe just a worn-out battery.

This is probably due to the OS crashing. If your sure the battery’s working *try double checking?* hold down the power button for 10 seconds. Or you could reset the firmware:

Plug in the power cable. Along with the power button, press Shift + Control + Option  key at the same time. Release all the four buttons at the same time. Press the power button and see if your Mac turns on.

If none of this works try getting in touch with a service executive

Not sure if I wasn’t clear in my question, but the MacBook isn’t turning on... and I have tried the key combos... they don’t work. How do I double check the battery’s working when it won’t turn on??? Also I can’t get in touch with a service executive at the moment. This answer doesn’t really address the question at all.

I have just come across this problem as well. I’m not sure if you’ve noticed but your Macbook may run so quietly, when turned on, that you don’t notice it’s on. You can try the control+alt+shift+power button for 10 seconds. When you let go the computer will be shut down completely. Press down on the track pad and you will notice it has no give. Press the power button and try pressing down on the trackpad. If you feel it click a little, that means the Macbook is turning on. Chances are the display is dead at this point. Easiest and cheapest thing you should try is connecting it through HDMI to a display or TV. If it comes on, this reinforces the fact that the display is dead. You can just use a display/TV, which will inevitably make it an at home computer instead of a take anywhere you want laptop. That is the cheap option, as you can also purchase a display for it to replace the current screen. This may come out to $400-$500 depending on your model though.
