No Power, Not Charging

My Macbook Air A1369 wont power on. My battery died already, so whenever I want to use it, I need the AC power connected. Then this morning when I tried using it, the magsafe indicator light wont turn on. tried using another 45W magsafe adaptor and still wont work. I used both magsafe adaptors on another Macbook Air and they both work. Does anyone know why my Macbook wont turn on?

I would replaced the DC-In board first. There are five different units in the A1369 line, to get you to the correct part and installation guide we need the last three figures of your serial number: http://everymac.com/ultimate-mac-lookup/...

you can do first is SMC reset by pressing and holding 4 buttons on the keyboard to reset all the system hardware . press and hold ( Left Shift+option+command+ power button ) for approx 5 seconds then put the charger inside then check its charging or not . if still not light in the charger remove the charger . hold the power button and put the charger in after pressing and holding power button after 10 sec release the power up button and press it again . your system will boot up may be . if boot up donot remove the charger . use it for a while and check its charging or not . if not then restart it from the mac osx . if still not power up then your have to open it up for checking whats wrong inside .

I fixed the MagSafe charger no light no power issue. (I cleaned the plug and reset SMC before.)

1. Unplug the power adapter from power source.

2. Waiting for 1 minutes.

3. Uninstall the fuse from power adapter (check it is work or not)

4. Install the fuse into power adapter.

5. Using power meter, set it to "10k Ohm".

6. Use red line connect to first point. black line connect to second point. Until you got data.

7. Use red line connect to first point. black line connect to center point. Until you got data.

8. Use red line connect to first point. black line connect to fourth point. Until you got data.

9. Use red line connect to first point. black line connect to fifth point. Until you got data.

10. Please plug to power source and your mac again. It will have light and power.

How about creating your own question with all of your details as this question is quite old and I'm sure you don't have the same problem.

I had same issue with my macbook air. No boot and no charging. SMC reset didn't work. Unpluging charger and heating with dryer didn't work either. The solution was to open it up, unplug the battery from main board, wait half an hour and I could boot macbook. I noticed that battery was already 40% charged when it started up again, so macbook not being able to start was not due to low battery. It was due to some kind of crash or soft malfunction which entirely prevented macbook from booting until battery was unplugged from motherboard.
