Laptop gives different no.of beeps when trying to power on the laptop Studio 1555

While I was using my laptop it went off and afterwards, when I press the power button while connected to the power adapter, the laptop gives 3, 4, 5 and 7 beeps randomly and does not on.

Also the power adapter indicator is on but the Laptop power indicator and charging indicators are off.

I tried removing the battery and also cleaned the RAM.
