MacBook air won't startup unless power button held on for long time.

MacBook air won't startup unless power button held on for long time.

I was working on my MacBook air . Suddenly the screen went to sleep mode. When I tried to put it back by pressing the power button the keyboard lit but the screen did not. So I forced shutdown by holding the power button but then I could not start it normally until I had to long press the power button and kept it pressed till the apple logo comes on the screen. If I leave the power key before The apple logo appears it does not turn on . Now after turning on it takes !&&*.lot of time to boot(around 5 mins) after booting the system is too slow.
