Was the MacBook dropped or exposed to liquid?

Press and release the power button and then hold down CMD+option+P+R?

Reset NVRAM on your Mac - Apple Support

If one or more settings stored in NVRAM don't work as expected on an Intel-based Mac, resetting NVRAM might help.

If you have the pentalobe screwdriver to remove the bottom cover, disconnect the battery, wait about 30 minutes, connect the charger and see if the Macbook powers up on its own without pressing the power button.

Are the charger and battery working? if I remember correctly the air will not start without a battery.

 

[Audit13]

The air and pro can boot to the desktop with a battery, it will just be sluggish because the OS will throttle the CPU is a battery is not connected.

Sorry for delay in reply i could not found the screwdriver , but i connected it without battery same thing is happening fan suns for 2-3 seconds but nothing on the screen. Is there anything else that i can try ?

 

[Anjul_01]

here's how it is happening without battery connected , same is with battery connected @Audit13 ,@mba2015

 

[Audit13]

The Air powers up by itself when the battery is disconnected and charger is connected?

Turn the Air on its side and look to see if the fan starts and stops or it starts off at full speed and then slows down.

 

[Anjul_01]

it just starts at full speed and keep on running at full speed with some jerks in middle . i think its just broken now n i should try to find another . But really really Thanks for trying to Help , appreciate it @Audit13

With the fan running at full speed, the Air may need an SMC reset.

 

[Anjul_01]

i unplugged the battery for 1 hour, wouldnt it have reset SMC?

 

[Audit13]

Nope, unplugging the battery doesn't reset the SMC.

 

[Anjul_01]

Nope, unplugging the battery doesn't reset the SMC.

but i tried combinations to reset SMC and also to reset NVRM , both didnt work, what can i do now to must sure it resets ?

 

[Audit13]

If the MacBook doesn't chime, it's not possible to reset SMC as far as I know.

 

[Anjul_01]

so basically only choice i have now is to either buy new or take it to proper service center right ?

Looks like a trip to the repair shop is in order.
